Analysis response reference

The structure returned by POST /api/protocols/v2/analyze, per activity type.

Every family is documented, and the field lists have been verified against the live API. One assessment is documented from its result definition only, because no recording of it was available: posture pictures.

The envelope

Every analyse call returns the same outer structure, irrespective of the activity types involved.

POST /api/protocols/v2/analyze?detailed=false
[ "f8055bc0-…" ]

→ {
    "protocolsResults": [
      {
        "protocolCode": "f8055bc0-…",
        "activitiesResults": "{ … }"      ← stringified JSON, shape depends on activity type
      }
    ]
  }

Reading `activitiesResults`

This field is a string containing JSON, not a nested object. It must be parsed a second time before use:

const results = JSON.parse(protocolResult.activitiesResults);

The contents of the parsed object depend on the exerciseType and activityType of the activity analysed. A strength test and a balance test return different measures, so no single schema covers all of them.

The `detailed` flag

Value	Returns	Use when
`false` (default)	Summary values per activity	Lists, dashboards and progression over time.
`true`	Adds the per-repetition breakdown	Rendering a single session in detail. The response grows considerably.

Result families

A family corresponds to an interface — the measurement method chosen when an activity is created. Every activity built on the same interface returns the same result structure, whichever body part or assessment it belongs to.

A practitioner arrives at an interface in one of two ways:

By picking a ready-made assessment — Assessments, then the sensor. Choosing K-Grip there offers Grip Strength, which is built on the Max Evaluation interface.
By building a custom activity — the creation wizard's Interface tab lists the interfaces available for the selected sensor. With K-Grip selected, Max Evaluation is one of them.

Either route produces the same result shape, so the interface is what determines how a response should be read.

Families divide the same way the application does: assessments, which measure a participant's current capacity, and training, which prescribes work against a reference an assessment has already established.

Family	Sensors	What the interface assesses
Assessments
Max Evaluation Endurance	K-Grip, K-Pull, K-Move, K-Bubble, K-Myo	Max Evaluation — the maximal capacity in a specific situation. The max corresponds to 100% of the participant's abilities: a short, strong effort, useful as a work reference. Endurance — the ability to keep a physical effort over time: a long, sustained effort, described best by the average.
Jump Analysis	K-Plates, K-Deltas, K-Deltas 3D	Jump height together with the propelling parameters, thrust and rate of force development.
Stance Evaluation	K-Plates, K-Deltas, K-Deltas 3D	Centre-of-pressure parameters while standing: surface, displacement and amplitude.
Dynamic Report	K-Plates, K-Deltas, K-Deltas 3D	Ground reaction forces measured while moving: squats, hops, landings and changes of direction, including the single-leg hop, skater jump, forward horizontal jump and drop and side jump.
Total Evaluation	K-Plates, K-Deltas, K-Myo	A single effort measured across both limbs at once, such as the isometric mid-thigh pull. Includes the body-weight measurement.
Nordic Hamstring	K-Pull, K-Deltas	The Nordic hamstring test, in a standard and an advanced variant.
K-Power field tests	K-Power	Sprint, long sprint, agility, ADA and 3-hop field tests. Barbell lifts recorded with K-Power are not here — they are a Dynamic Report.
Timed functional tests	K-Move, K-Plates	Timed up and go, climbing nine stairs, and tests combining two device types.
Records without a measurement	no sensor	Posture photographs, free-timer activities and free-mode records.
Questionnaires	no sensor	Answers scored into an index: WOMAC, IKDC, VISA, ODI, FAAM and related instruments.
Training
Rep Count	K-Grip, K-Pull, K-Power	Work in a targeted way against an assessment reference, over a set number of repetitions and a target expressed as a percentage of the max.
Isometric	K-Grip, K-Pull, K-Myo	A sustained, static contraction held in an unchanged position, over a number of repetitions and against a target.
Tempo	K-Grip, K-Pull, K-Myo	Repetitions performed to a controlled speed, with the eccentric, isometric, concentric and rest phases timed separately.
Static Distribution	K-Plates, K-Deltas	Holding a target weight distribution for as long as possible, scored on time spent on target.
Games	K-Plates, K-Deltas	Rehabilitation games, scored by the training mode the game was configured with.

Family names below the documented one are provisional and will be revised as each is written.

An activity records which of the two it is in its activityType: EVALUATION or EXERCISE. The grouping above reflects how each interface is normally used rather than a restriction — the result structure a family returns is the same either way.

Max Evaluation and Endurance K-Grip, K-Pull, K-Move, K-Bubble, K-Myo

One sensor, one effort at a time. Max Evaluation captures the strongest moment of a short effort; Endurance captures how well an effort is held over time. Both return the structure below, so they are documented together.

The built-in Grip Strength assessment is a Max Evaluation on K-Grip, and is used as the worked example throughout this section.

Which activities land here

Any activity built on the Max Evaluation or Endurance interface, on any of these sensors:

Device	`_device`	What it measures	Unit
K-Grip	KFORCE_GRIP	Grip force. This is the sensor behind the built-in Grip Strength assessment.	Kg
K-Pull	LINK	Pull and push force, for manual muscle testing against a fixed point or a strap.	Kg
K-Move	SENS	Joint angle, for range-of-motion measurements.	°
K-Bubble	BUBBLE	Force applied through an inflatable tool. The tool is already accounted for during measurement, so the value arrives as a force.	Kg
K-Myo	EMG	Muscle activation. Values are carried in `_emgChannelsData`; the force fields read zero.	see EMG

The field that selects the family is the activity's exercise type — here METER or METER_ENDURANCE. That field will be documented alongside the protocol structure; it is named here only so the routing can be traced in full.

Units depend on the device

The primary measurement carries a different quantity per device. The same fields hold force, angle or pressure depending on the sensor used:

K-Grip, K-Pull and K-Bubble report kilograms-force. K-Move reports degrees of rotation. K-Myo reports zero in every force field and carries its values in _emgChannelsData instead.

The tables below write this shared unit as Kg | °. The sensor is identifiable per repetition from _device.

_deltas	array	—	Delta stream stored alongside the samples in the measurement cache.
_syncedSamples	array	—	Samples aligned across devices, for activities recording from more than one sensor.

Jump Analysis K-Plates, K-Deltas, K-Deltas 3D — five variations

Jump height and the propelling parameters behind it, measured from a force platform: how the participant unweights, brakes, propels, takes off and lands.

Which activities land here

Activities recorded on K-Plates, K-Deltas or K-Deltas 3D with a jump interface. The analyzer is chosen by the jump performed and by whether it is done on one leg or two — never by the platform, so all three record the same structure.

The jumps

Three single jumps are recognised, reported in the jumpType field:

`jumpType`	Jump	What the participant does
CMJ	Counter Movement Jump	Starts standing, dips into a countermovement and jumps straight up in one continuous action.
SJ	Squat Jump	Starts from a held squat with no countermovement, so the propulsion is measured without the stretch-shortening contribution.
DROP	Drop Jump	Steps off a box, lands, and rebounds immediately. This is the jump the reactive strength fields describe.
MULTIPLE_JUMPS	Repeated jumping	Continuous jumping over a set duration rather than a single effort.

The five variations

Variation	Covers	Result shape
Jump Analysis	CMJ, SJ and DROP performed on two legs, together with custom single jumps.	22 summary fields, then one entry per jump with the full breakdown.
Unipodal Jump	CMJ, SJ and DROP performed on one leg.	The same measurements per side, with the two-platform fields removed.
Multiple Jumps	Repeated jumping on two legs over a set duration.	Fatigue and pace across the set, then one short entry per jump.
Multiple Single-Leg Jumps	Repeated jumping on one leg.	One entry per side, each summarising that side’s set.
Skipping	Skipping over a set duration.	Skip count and airborne time, then one entry per cycle.

On K-Deltas 3D each foot is recorded by its own sensor, reported as DELTAS_3D_LEFT and DELTAS_3D_RIGHT. The per-side fields are populated the same way as for a pair of platforms.

How the field names are built

The jump result carries a large number of fields, but they are combinations of a smaller set of measurements with four consistent modifiers. Learning the modifiers makes the whole set readable.

Pattern	Meaning	Example
relative…	The same measurement normalised to the participant. Where the base field is in newtons the relative form is in N/kg, and where it is in watts the relative form is in W/kg.	relativeMaxForce
…Left / …Right	The value from one platform only. The unmodified field is the combined total.	maxPowerLeft
…L / …R	The same per-side split, in the shorter form used by a few older fields.	rfdAverageL
…Pair	An object `{"_force", "_time"}` carrying a value together with the moment it occurred.	maxValuePair

The base measurement maxPower therefore appears as maxPower, maxPowerLeft, maxPowerRight, relativeMaxPower, maxPowerPair and so on. 217 per-jump fields reduce to roughly 87 measurements once the modifiers are set aside.

timeOnAirBothSides	number
totalSkips	number

With `detailed=true`

Each jump additionally carries the raw platform signal: _totalForces, _leftForces, _rightForces, _velocities, _accelerations, _displacement, _powers, _powersLeft, _powersRight, _deltas and _syncedDataPerDevice. Multiple Jumps adds _syncedForces at the top level instead; Skipping adds _leftForces and _rightForces.

Stance Evaluation K-Plates, K-Deltas, K-Deltas 3D — five variations

How steadily a participant holds a position. The measurement follows the centre of pressure — the point under the foot through which body weight acts — and describes how far and how quickly it wanders while the position is held.

Which activities land here

Activities recorded on K-Plates, K-Deltas or K-Deltas 3D with a stance interface. The analyzer is chosen by how many feet are being measured and how many sensors are used:

Variation	Setup	Result shape
Bipodal stance	Standing on two sensors, one per foot.	36 fields per repetition, with centre-of-pressure measures for each foot and for both combined.
Bipodal drop-land	The same, landing from a drop rather than standing still.	As above plus `_dropLandResults`.
Unipodal stance	Standing on one foot, one sensor.	18 fields per repetition, with a single set of centre-of-pressure measures.
Unipodal drop-land	Landing on one foot.	As above plus `_dropLandResults`.
Heel-tip and lateral stance	One foot across two sensors, separating heel from forefoot.	A shorter, differently named summary. See below.

Every variation returns _repResults, one entry per repetition, and includeAllFields. Everything else sits inside the repetition.

Dynamic Report K-Plates, K-Deltas, K-Deltas 3D, K-Power — eleven variations

Ground reaction forces measured while the participant moves. Where the stance family describes standing still, this one covers movement: squats, push-ups, barbell lifts, hops, landings and changes of direction.

Which activities land here

This is the broadest interface in the API. Eleven analyzers sit behind it, chosen by the assessment selected, and they produce three quite different kinds of result.

Repetition sets

A set of repetitions of the same movement, described by how load was shared and how the set progressed.

Variation	Covers	Shape
Limb distribution	Squats analysis, push-up analysis, flywheel squats — anything recorded on two platforms without a more specific assessment.	39 fields per set, describing the left/right split at several load intensities.
Single-leg distribution	Single leg squat and single leg squats, with a motion sensor recording joint angle alongside the platform.	13 fields per set.
K-Power velocity-based training	Barbell lifts recorded with K-Power: squat, bench press and Bulgarian squat.	17 fields per set, described by bar speed rather than by force.
Advanced analysis	Squats Advanced Analysis and Push-up Advanced Analysis.	no sample available

Ground-contact tests

A single effort measured from contact to take-off, or through a landing. Five of these six share a core set of fields and add their own measures on top.

Variation	Covers	Adds
Change of direction	Planting and pushing off in a new direction.	Entry and exit impulse and velocity, medio-lateral and anterior-posterior peak force, reactive strength index.
Single-leg hop	Hopping forward on one leg.	Distance, take-off angle, three-axis peak force, rate of force development.
Skater jump	Bounding sideways from one leg to the other.	Flight time, distance, entry and exit measures, separate horizontal and vertical peak forces.
Forward horizontal jump	Jumping forward for distance.	Distance, horizontal impulse and velocity, a horizontal reactive strength index.
Drop and side jump	Dropping down then jumping sideways.	Entry and exit impulse and velocity, vertical and lateral peak force.
One-two vertical jump	A two-step vertical jump, each foot landing separately.	Reports per foot rather than per effort, so it does not follow the shared core.

Single-leg hop returns two arrays, _resultsModelsTakeOff and _resultsModelsLanding. Every other variation returns a single _resultsModels.

Gait on K-Deltas 3D

Gait analysis recorded on K-Deltas 3D also routes here. no sample available

Total Evaluation K-Plates, K-Deltas, K-Myo — three variations

A single effort measured across both limbs at once, with each platform reporting its own contribution. The isometric mid-thigh pull is the assessment this family was built for.

Which activities land here

Activities on the Total Evaluation interface. Three variations, selected by the assessment and by whether an EMG sensor is attached:

Variation	Covers	Shape
Total evaluation	Bilateral force tests such as the isometric mid-thigh pull, on two platforms.	10 summary fields, then 42 per repetition.
Total evaluation with EMG	The same test with a K-Myo sensor attached.	Muscle activation only: 4 summary fields, 4 per repetition.
Body weight	Standing on the platforms to record body weight.	A single value. No repetitions.

Relationship to Max Evaluation

The main variation reuses the force and rate-of-force-development vocabulary of the Max Evaluation family. Of its 42 per-repetition fields, 20 carry the same name and meaning as they do there. The remaining 22 are the per-side splits this family adds, together with the force-at-100 ms measures.

Fields present in Max Evaluation but absent here: device provenance (_device, _serialCode, _measurementVersion, _frequency), torque, _netMaxForce, _rfd20To80FMax, _maxTimeOnTarget, and the rate and impulse series.

There is no _maxRightValue. Every other measure has an explicit Left and Right pair, but the right-side peak is not serialised. It is derived, and a client needs to compute it:

right peak = _maxValue − _maxLeftValue

Total evaluation — summary

Aggregates across the repetitions, per side.

Field	Type	Unit	Meaning
_deviationsOfMaxForceLeft	number	Kg	Standard deviation of the peak across repetitions, left.
_deviationsOfMaxForceRight	number	Kg	The same on the right.
_deviationsOfRfdLeft	number	Kg/s	Standard deviation of the rate of force development, left.
_deviationsOfRfdRight	number	Kg/s	The same on the right.
_meanOfMaxLeft	number	Kg	Mean of the per-repetition peak on the left.
_meanOfMaxRight	number	Kg	The same on the right.
_meanRfdLeft	number	Kg/s	Mean rate of force development on the left.
_meanRfdRight	number	Kg/s	The same on the right.
_resultsPerRep	array<object>	—	One entry per repetition.
includeAllFields	boolean	—	Mirrors the detailed query parameter.

Total evaluation — per repetition

Shared with Max Evaluation

Same names, same meanings. See that family for the full descriptions.

Field	Type	Unit	Meaning
_averageRfd	number	Kg/s
_averageValue	number	Kg	Mean force across the repetition, both sides.
_forceAtRfdEndTime	number	Kg
_forceAtRfdStartTime	number	Kg
_forceAtRfdStartTime200MsBefore	number	Kg
_forcesAtSteps	array<number>	Kg	Force at 50, 100 and 250 ms after the pull begins.
_impulse	number	N·s	Area under the curve, both sides. Converted to newtons.
_maxValue	number	Kg	Peak force from both platforms combined.
_repOrdinal	number	index	Position of the repetition, starting at 1.
_repSide	string	—	Side recorded. BOTH for a bilateral test.
_rfdEndTime	number	s
_rfdFromMax	number	Kg/s
_rfdStartTime	number	s
_rfdStartTime200MsBefore	number	s
_rfdToMax	number	Kg/s
_rfdToMaxEndTime	number	s
_rfdToMaxEndTimeForce	number	Kg
_rfdToMaxStartTime	number	s
_rfdToMaxStartTimeForce	number	Kg
_timeToMax	number	ms	Time from the start of the pull to the peak.

Added by this family

Field	Type	Unit	Meaning
_averageLeftValue	number	Kg	Mean on the left.
_averageRfdLeft	number	Kg/s
_averageRfdRight	number	Kg/s
_averageRightValue	number	Kg	Mean on the right.
_forcesAtStepsLeft	array<number>	Kg	The same on the left.
_forcesAtStepsRight	array<number>	Kg	The same on the right.
_impulseLeft	number	Kg·s	The same on the left, not converted.
_impulseRight	number	Kg·s	The same on the right, not converted.
_maxLeftValue	number	Kg	Peak force on the left platform.
_rfdFromMaxLeft	number	Kg/s
_rfdFromMaxRight	number	Kg/s
_rfdToMaxLeft	number	Kg/s
_rfdToMaxRight	number	Kg/s
_timeToMaxL	number	ms	The same on the left.
_timeToMaxR	number	ms	The same on the right.
_valueAt100ms	number	Kg	Force reached 100 ms after the pull begins.
_valueAt100msLeft	number	Kg	The same on the left.
_valueAt100msRight	number	Kg	The same on the right.
_valueAt100msToMaxValuePercentage	number	%	Force at 100 ms as a share of the peak.
_valueAt100msToMaxValuePercentageLeft	number	%	The same on the left.
_valueAt100msToMaxValuePercentageRight	number	%	The same on the right.
_weight	number	Kg	Participant body weight recorded with the test.

_timeToMaxL and _timeToMaxR use the short per-side suffix; every other pair in this family uses Left and Right in full.

Total evaluation with EMG — per repetition

When a K-Myo sensor is attached the force measures are replaced entirely by muscle activation.

Field	Type	Unit	Meaning
_emgDataLeft	object	—	Per-channel EMG results for the left side.
_emgDataRight	object	—	The same for the right.
_repOrdinal	number	index	Position of the repetition, starting at 1.
_repSide	string	—	Side recorded. BOTH for a bilateral test.

The summary carries _maxPerSideEmg and _minCoactivationIndex alongside _resultsPerRep.

Body weight

The shortest result in the API. No repetition array is returned at all.

Field	Type	Unit	Meaning
includeAllFields	boolean	—	Mirrors the detailed query parameter.
weight	number	Kg	Body weight measured by the platforms.

With `detailed=true`

The main variation adds the raw signal per side — _forcesLeft, _forcesRight, _deltas, _syncedSamples — together with the rate and impulse series that the summary omits: _rfds, _rfdsSince0, _impulses, _impulsesSince0 and their per-side variants. The EMG and body weight variations add nothing.

Static Distribution K-Plates, K-Deltas — one variation

A training exercise rather than a measurement. The participant holds a target weight distribution for as long as they can, and is scored on how much of the set duration they stayed on target.

Which activities land here

Activities on the Static Distribution interface, recorded on K-Plates or K-Deltas. A single analyzer serves the whole family, so there are no variations to distinguish.

The built-in assessment is Weight static distribution. Its activityType is EXERCISE: the result is a score, not a set of biomechanical measures, which is why this family sits under training rather than assessments.

How the score is produced

Each repetition is scored on the time spent above the configured target.

Success is that time as a share of the configured set duration — hold the target for the whole set and it reaches 100%.
Points are derived from the same time together with the difficulty setting of the activity, so the same hold scores differently at different difficulties.

The per-repetition values are formatted strings, not numbers. This family returns display text rather than measurements:

_ordinal is "1st", "2nd", "3rd" — not an integer. _points is a number rendered as a string, "12.5". _success carries its own percent sign, "87%".

Only the two summary fields are numeric. Anything charted from the repetition array has to be parsed first.

Summary

Field	Type	Unit	Meaning
includeAllFields	boolean	—	Mirrors the `detailed` query parameter.
maxPoints	number	points	Highest points scored by any single repetition.
maxSuccess	number	%	Highest success percentage reached by any single repetition. Numeric, with no percent sign.
_repResults	array	—	One entry per repetition.

Per repetition

Field	Type	Unit	Meaning
_ordinal	string	—	Position of the repetition as an ordinal word: `"1st"`, `"2nd"`, `"3rd"`.
_points	string	points	Points scored, rounded to one decimal place and rendered as a string. Derived from the time on target and the difficulty setting.
_success	string	%	Time on target as a share of the set duration, rendered with a trailing percent sign.

Repetitions are padded so the result always holds at least nine entries. The padding entries carry empty strings in every field — skip any entry whose _ordinal is empty.

With `detailed=true`

Each repetition adds _syncedSamples, the raw platform signal aligned across the sensors. Nothing is added at the top level.

Nordic Hamstring K-Pull, K-Deltas — two variations

The Nordic hamstring curl: the participant is held at the ankles and lowers forward under control, resisting for as long as possible. The test measures how much force each leg holds and how quickly that force fades.

Which activities land here

Nordic hamstring activities on K-Pull or K-Deltas, in a standard and an advanced variant. The advanced variant is selected by the assessment chosen.

Standard — per repetition

Every measure is reported for the set as a whole and again per leg, which is what makes this test useful for spotting an imbalance.

Field	Type	Unit	Meaning
_average	number	Kg
_averageLeft	number	Kg
_averageRight	number	Kg
_fatigue	number	%	Drop in force from the start of the effort to the end.
_fatigueLeft	number	%
_fatigueRight	number	%
_leftMaxForce	number	Kg	Peak force on the left.
_rfd	number	Kg/s
_rfdLeft	number	Kg/s
_rfdRight	number	Kg/s
_rightMaxForce	number	Kg	Peak force on the right.
_timeToMax	number	ms
_timeToMaxLeft	number	ms
_timeToMaxRight	number	ms

Fatigue is the drop in force between the beginning and the end of the hold, so a higher value means the leg gave out faster.

Advanced

The advanced variant returns a single _resultsModel object rather than an array of repetitions. no sample available for its inner fields.

With `detailed=true`

The standard variant adds _syncedForcesLeft, _syncedForcesRight and _syncedTimestamps — the force trace for each leg against a shared clock.

K-Power field tests K-Power — five variations

Running tests recorded in the field rather than on a platform. K-Power tracks the athlete over the ground and derives speed, acceleration and the force behind them.

Which activities land here

Activities on the Sprint interface, recorded with K-Power. Barbell lifts recorded with the same sensor are not here — those are a Dynamic Report.

Variation	Covers	Sample
Sprint	A straight-line sprint over a configured distance.	—
Agility test	Out, turn, and back — the 505 change-of-direction test.	—
Long sprint	A sprint over a longer distance.	no sample available
ADA test	Acceleration-deceleration ability.	no sample available
3-hop test	Three consecutive hops for distance.	no sample available

All five return _repResults, one entry per attempt.

Timed functional tests K-Move — three variations

Everyday movements timed from a motion sensor. The result is a set of durations, one per phase of the test, rather than a repetition array.

Which activities land here

Timed functional assessments recorded on K-Move. Unlike every other family these return their measures at the top level, with no per-repetition array at all.

Timed up and go

Rise from a chair, walk out, turn, walk back, and sit down. Each phase is timed separately.

Field	Type	Unit	Meaning
durationFirstTurn	number	s	Time for the first turn.
durationSecondTurn	number	s	Time for the second turn.
durationSitToStand	number	s	Time to rise from the chair.
durationStandToSit	number	s	Time to sit back down.
durationTotal	number	s	Total time for the test.
durationWalkBack	number	s	Time walking back.

Field	Type	Unit	Meaning
durationTotal	number	s	Total time for the test.
durationTurn	number	s	Time for the turn.
durationWalkBack	number	s	Time walking back.
durationWalkForward	number	s	Time walking out.
includeAllFields	boolean	—

Two-device test

Records without a measurement no sensor — three variations

Activities that record something against a participant without producing an analysed measurement: a stopwatch, a free-form capture, or photographs.

Which activities land here

Variation	Covers	Returns
Timer activity	An activity timed with a stopwatch rather than a sensor.	`_repResults`
Free mode	A free capture that stores the raw measurement without scoring it.	`_resultsPerMeasurement`
Posture pictures	Photographs taken to document posture.	`_resultModels` no sample available

Each uses a different name for its array. Note in particular that free mode returns _resultsPerMeasurement, keyed by measurement rather than by repetition.

Timer activity — per repetition

Field	Type	Unit	Meaning
_finishTimestamp	number	epoch ms	When the activity was completed.
_startTimestamp	number	epoch ms	When timing began.
_stopTimestamp	number	epoch ms	When timing was stopped.
_time	number	ms	Elapsed time recorded by the stopwatch.

Free mode — per measurement

The only family that returns the measurement itself rather than anything derived from it.

Field	Type	Unit	Meaning
bluetoothDeviceType	string	—	Bluetooth identifier of the sensor.
deviceSerialCode	string	—	Serial number of the sensor.
deviceType	string	—	Sensor family.
emgResults	object	—	EMG results, where an EMG sensor was used.
measurementCode	string	—	Code of the measurement.
order	number	index	Position of the measurement within the activity.
samplesValues	array	—	The recorded samples.
syncedSamples	array	—	The same samples aligned across devices.

Questionnaires no sensor — fourteen instruments

Answers scored into an index. No sensor is involved: the participant completes the instrument and the result is the score.

Which activities land here

Questionnaire activities. Most return a single _score; a few report sub-scores or per-side values instead, which is the only thing that varies between them.

The instruments

Instrument	Assesses	Fields
WOMAC	Osteoarthritis of the hip or knee.	`_score`
IKDC	Knee function and symptoms.	`_score`
VQ-11	Quality of life with chronic respiratory disease.	`_functional_score`, `_psychological_score`, `_relational_score`, `_score`
EIFEL	Low back pain and disability.	`_score`
ACL-RSI	Psychological readiness to return to sport after anterior cruciate ligament injury.	`_score`
ALR-RSI	Readiness to return to sport after ankle ligament injury.	`_score`
SI-RSI	Readiness to return to sport after shoulder instability.	`_score`
QASLL	Quality of a single-leg landing, scored from observed criteria.	`_hasCheckedHealthySideKneePositionQuestion`, `_hasCheckedInjuredSideKneePositionQuestion`, `_healthyScore`, `_injuredScore`, `_penaltyPoints`
FASH	Achilles tendinopathy in athletes.	`_score`
VISA	Tendinopathy severity, in several site-specific versions.	`_score`
ODI	Oswestry disability index for low back pain.	`_score`
FAAM	Foot and ankle ability.	`_adlScore`, `_sportsScore`
K-Start	A battery of hop tests, healthy side against injured side.	`_crossoverHopHealthyValues`, `_crossoverHopInjuredValues`, `_singleHopHealthyValues`, `_singleHopInjuredValues`, `_tripleHopHealthyValues`, `_tripleHopInjuredValues`
S-Start	A shoulder battery of strength and reach measures, per side.	`_ckcuestMInputs`, `_extensionFlessumLeftInputs`, `_extensionFlessumRightInputs`, `_imvcExternalLeftInputs`, `_imvcExternalRightInputs`, `_imvcInternalLeftInputs`, `_imvcInternalRightInputs`, `_uqYbtLeftInferolateralInputs`, `_uqYbtLeftMedialInputs`, `_uqYbtLeftSuperolateralInputs`, `_uqYbtRightInferolateralInputs`, `_uqYbtRightMedialInputs`, `_uqYbtRightSuperolateralInputs`, `_ussptLeftInputs`, `_ussptRightInputs`

Every result also carries includeAllFields. Scores are numbers; the scale differs per instrument and is defined by the instrument itself, not by this API.

The ones that are not a single score

VQ-11 reports _score alongside three sub-scores: _functional_score, _psychological_score and _relational_score. Note the underscore-separated naming, which is unique to this instrument.
FAAM reports two independent scores, _adlScore for daily living and _sportsScore, with no combined total.
QASLL reports _healthyScore and _injuredScore with _penaltyPoints, plus two booleans recording whether the knee-position criterion was checked on each side.
K-Start and S-Start return arrays of raw inputs per test and per side rather than a score — six arrays and fifteen arrays respectively.

With `detailed=true`

Nothing is added. Questionnaire results carry no signal.

Rep Count K-Grip, K-Pull, K-Power — one variation

Training against a reference established by an assessment: a set number of repetitions at a target expressed as a percentage of the participant’s maximum.

Which activities land here

Activities on the Rep Count interface. Where the sensor is K-Power the activity is analysed as a Dynamic Report instead, so what follows is the K-Grip and K-Pull case.

Summary

Field	Type	Unit	Meaning
_repResults	array	—	One entry per repetition.
_maxForce	number	Kg	Highest force reached across the set.
_average	object	—	Running mean across the set.
_forces	array	Kg	Force trace for the whole set.
_currentCycleForces	array	Kg	Force trace of the repetition in progress.
_repCountCycles	array	—	Start and end of each detected repetition.
_forceTransformer	object	—	Filter applied to the raw signal.
includeAllFields	boolean	—	Mirrors the `detailed` query parameter.

Per repetition

Field	Type	Unit	Meaning
_average	number	Kg	Mean force across the repetition.
_max	number	Kg	Peak force in the repetition.
_pace	number	reps/min	Rate the repetitions were performed at.
_repCycles	array	—	Start and end of the repetition.
_side	string	—	Body side recorded.
_signal	object	—	Force trace for the repetition.
_successRate	number	%	Share of the repetition spent at or above the target.

Isometric K-Grip, K-Pull, K-Myo — three variations

A contraction held still against a target for a set time. The participant is scored on how much of the repetition they kept the force inside the target band.

Which activities land here

Variation	Setup	Shape
Isometric	One sensor, or a K-Myo recording muscle activation.	Success rate per side, then one entry per repetition.
Isometric with EMG	A single K-Myo sensor.	The same shape, with the EMG channel flag.
Isometric, two devices	Two sensors held simultaneously.	A single success rate, and per-repetition entries carrying both devices.

Isometric — per repetition

Field	Type	Unit	Meaning
_averageValue	number	Kg
_bottomBoundTarget	number	Kg	Lower edge of the target band.
_hasSecondChannel	boolean	—	Whether a second EMG channel was recorded.
_maxTimeOnTarget	number	ms	Longest unbroken spell inside the target band.
_maxValue	number	Kg
_repOrdinal	number	index	Position of the repetition, starting at 1.
_repSide	string	—	Side recorded.
_rfdFromMax	number	Kg/s
_rfdToMax	number	Kg/s
_successRate	number	%	Share of the repetition spent inside the target band.
_target	number	Kg	Target force the repetition was performed against.
_timeToMax	number	ms
_totalTimeOnTarget	number	ms	Total time inside the target band.
_upperBoundTarget	number	Kg	Upper edge of the target band.

The target is a band, not a single value: _bottomBoundTarget and _upperBoundTarget are its edges, and _successRate is the share of the repetition spent between them.

Two devices — per repetition

Field	Type	Unit	Meaning
_averageValue	number	Kg
_bottomBoundTarget	number	Kg	Lower edge of the target band.
_leftDevice	string	—	Bluetooth identifier of the left sensor.
_maxTimeOnTarget	number	ms	Longest unbroken spell inside the target band.
_maxValue	number	Kg
_pieEntries	array<unknown>	—	Share of the set spent below, inside and above the target band.
_repOrdinal	number	index	Position of the repetition, starting at 1.
_rfdFromMax	number	Kg/s
_rfdToMax	number	Kg/s
_rightDevice	string	—	Bluetooth identifier of the right sensor.
_successRate	number	%	Share of the repetition spent inside the target band.
_timeToMax	number	ms
_totalTimeOnTarget	number	ms	Total time inside the target band.
_upperBoundTarget	number	Kg	Upper edge of the target band.

This variation reports maxSuccessRate at the top level as a plain number, where the other two report _avgSuccessRatePerSide and _maxSuccessRatePerSide as arrays keyed by body side.

With `detailed=true`

The single-sensor variations add _signal, _deltas and _syncedSamples. The two-device variation adds _forcesLeft, _forcesRight and _forcesTotal instead.

Tempo K-Grip, K-Pull, K-Myo — two variations

Repetitions performed to a controlled speed, scored on how much of each repetition the force stayed inside a target band.

Which activities land here

Activities on the Tempo interface, with or without a K-Myo sensor. Both variations return the same summary, and it is the same summary the Isometric family uses: the two interfaces score against a target band in the same way.

Summary

Field	Type	Unit	Meaning
_resultsPerRep	array	—	One entry per repetition.
_maxSuccessRatePerSide	array	%	Best success rate per body side, as `{_key, _value}`.
_avgSuccessRatePerSide	array	—	Mean success rate per side. The value is an object carrying `_average` and `_numOfItems`, not a plain number.
includeAllFields	boolean	—	Mirrors the `detailed` query parameter.

Per repetition

Field	Type	Unit	Meaning
_key	string	—
_value	number	—

With a K-Myo sensor

The EMG variation returns the same fields with two differences: _hasSecondChannel is added, and _pieEntries is not present.

Games K-Plates, K-Deltas — one variation

Rehabilitation games. The participant plays against a target and the result is a score, in the same spirit as Static Distribution.

Which activities land here

Game activities, scored by the training mode the game was configured with.

Summary

Field	Type	Unit	Meaning
_repResults	array<object>	—
difficultyLevel	number	level	Difficulty the game was configured at.
duration	number	ms
includeAllFields	boolean	—
totalScore	number	points	Score across the whole game.

Per repetition

Field	Type	Unit	Meaning
bodySide	string	—	Side recorded.
metas	object	—	Additional values recorded by the game.
ordinal	number	index	Position of the repetition.
repCode	string	—	Repetition the result belongs to.
score	number	points	Score for this repetition.
target	number	—	Target the repetition was played against.

metas carries values specific to the game being played, so its contents vary by game rather than being fixed by this family.
