📖 Static demo — read-only snapshot

You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:

  • Global search (sidebar) is disabled — it queries the API.
  • The JSON API and the API “Try it” playgroundaren’t included.
  • The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.

Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.

Neuromuscular Exercise (Step-Downs / Single-Leg Balance)

Draftbalance85%intermediate⬤ strong evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
standing on the involved leg on a step or floor, pelvis level, kneecap tracking over the second toe, opposite foot lifted
End
single-leg stance maintained through a slow step-down until the trailing heel lightly touches the floor, hip and pelvis staying level
Range of Motion
controlled single-leg knee flexion through the step-down descent (~0–45°) with proprioceptive/perturbation stance holds

How to Perform

Neuromuscular exercises improving sensorimotor control, functional stability, and fall risk in knee OA. Includes step-downs from various heights, single-leg balance, and perturbation training. Addresses proprioceptive deficits and mimics activities of daily living.

Coaching Cues

  1. 1

    Stable hip, level pelvis — glute med locks the alignment

    (verbal)
  2. 2

    Lower the trailing heel slowly to kiss the floor

    (verbal)
  3. 3

    Keep the kneecap aimed over the second toe

    (verbal)
  4. 4

    Hand on standing hip — feel it stay level

    (tactile)

Evidence-Based Dosing & EMG Data

Recommended Dosing

Progressive program over 12 weeks; step-down height and balance surface progress

Muscles Involved (5)

Primary Movers

Quadriceps Femoris— Eccentric control during step-downs
Gluteus Medius— Pelvic stability during single-leg stance

Secondary Movers

Hamstrings (Group)— Co-contraction for joint stability

Stabilizers

Gastrocnemius— Ankle strategy for balance
Soleus— Postural ankle stabilization

Easier Variations ↓

1

Double-Leg Mini Squat

Bilateral mini squats to build baseline quad strength before progressing to single-leg work.

2

Tandem Stance Balance

Stand with one foot directly in front of the other (heel-to-toe). Builds balance before single-leg stance.

Harder Variations ↑

1

Step-Down with Perturbation

Have a partner apply gentle pushes during single-leg stance or step-down. Trains reactive stability.

2

Single-Leg Squat

Full single-leg squat to chair depth. Advanced lower extremity control challenge.

3

Progress to single-leg-squat-pistol

AUDIT: Progress single-leg balance/step-down control to a full single-leg squat.

Research Notes

Evidence: neuromuscular exercises improve sensorimotor control, functional stability, and reduce fall risk in knee OA [Sharma 2021, Zeng 2022, Roos 2025]. Address proprioceptive deficits and mimic ADLs [Roos 2025].
