The GET /analysis/{analysis_id}/results response includes a search_key in each biomechanical item (under texts). Use this stable key for internal mapping (e.g. to your own labels, content, or translations) instead of relying on the human-readable position or title, which may be localized. The tables below list all possible search_key values per analysis type, with the associated position and a short explanation (from the English content assets).

Back view

Back view analysis returns analysis_content with knee_adduction, pelvic_drop, and pronation. Each side (left / right) has a texts.search_key.

Pelvic drop

search_keypositionexplanation
PelvicGPelvis alignedRight and left sides of pelvis are at the same height; ideal position.
PelvicOMild pelvic dropRight and left sides of the pelvis are not aligned; strengthen gluteal muscles, hamstrings, adductors and hip flexors.
PelvicBExcessive pelvic dropRight and left sides of the pelvis are not aligned; same strengthening and awareness as PelvicO with higher severity.

Foot posture (pronation)

search_keypositionexplanation
OverpronationOverpronationAbnormal pronation; foot moves inward; risk of injuries (e.g. shin splints, plantar fasciitis).
PronationPronationFoot moves inward; natural during contact; if excessive, risk of pain and need for proprioception work.
NeutralNeutralFoot straight, no pronation or supination; good position, can reinforce with proprioception.
SupinationSupinationFoot moves outward; natural when leaving the ground; excess can cause IT band, Achilles, foot issues.
OversupinationOversupinationAbnormal supination; risk of leg injuries, increased stiffness and impact.

Knee adduction

search_keypositionexplanation
ExcessiveAbductionExcessive abductionTibia away from midline, knee collapses inward; strengthen adductors, glutes, quadriceps; linked to knee valgus.
MildAbductionMild abductionSame direction as excessive but milder; knee inward relative to hip–ankle line.
KneeAlignedKnee alignedTibial movement parallel to midline; ideal knee position and efficiency.
MildAdductionMild adductionTibia toward midline, knee shifts outward; strengthen hip, gluteal, abdominal muscles; can be linked to knee varus.
ExcessiveAdductionExcessive adductionSame as mild adduction with higher severity; linked to knee varus.

Side view

Side view analysis returns analysis_content with arm, back_cycle, foot, forward_cycle, head, and trunk.

Arms position

search_keypositionexplanation
ArmBDOver-extensionElbow too open; loss of efficiency; maintain appropriate amplitude.
ArmBTExcessive flexionElbow too closed; risk of muscle tension; loosen fists and relax shoulders.
ArmGIdeal arm positionGood body stability and elbow angle; keep working on this position.
ArmODModerate extensionElbow too open; strain on back muscles; slightly bend the elbows.
ArmOTModerate flexionElbow too closed; increase arm swinging; relax shoulders and loosen fists.

Back knee angle at foot landing

search_keypositionexplanation
BackCycleBLow heel kickRestricted leg cycle; need more energy to maintain speed; sprint exercises to improve amplitude.
BackCycleGIdeal PositionGood spring effect of the leg; stride naturally wider; back knee angle is ideal.
BackCycleOOkay heel kickLimited propulsion; back knee too open; work on amplitude of hips and leg.

Front knee angle at foot landing

search_keypositionexplanation
ForwardCycleBExcessive flexionFront knee too closed; limited running efficiency; improve leg lift (e.g. skipping).
ForwardCycleGIdeal PositionFront knee angle is ideal; optimal running efficiency.
ForwardCycleOModerate flexionFront knee too closed; work on amplitude (e.g. stair climbing).

Head position

search_keypositionexplanation
HeadBDGaze too focused toward the groundGaze too low; lift gaze to improve posture; risk of slouched posture.
HeadBTGaze too much skywardGaze too high; align with horizon; risk of cervical pain.
HeadGGaze in ideal positionGood body balance; maintain this position.
HeadODGaze slightly toward the groundGaze too low; overuse of neck muscles; lift your gaze.
HeadOTGaze slightly skywardGaze too high; align head, neck, and back; risk of muscle tension.

Back position (trunk)

search_keypositionexplanation
TrunkBDThe torso is too leaned forward.Excessive tension in lumbar muscles; lift gaze to raise the torso.
TrunkBTNot leaning forward enoughTorso too leaned back; overload on lumbar and gluteal muscles; brace with neutral pelvis.
TrunkGThe torso is in an ideal position.Stride balance favored; stay braced.
TrunkODThe torso is slightly leaned forward.Slightly too far forward; straighten the torso.
TrunkOTNot sufficiently forward-leaningTorso too far back; engage abdominals to stabilize the back.

Using search_key in your integration

  • Prefer search_key for logic, routing, or mapping (e.g. to your own copy or assets).
  • Use position and title for display when needed.
