Lower Extremity Capacity Profile

Research-Informed Clinical-Performance Assessment Framework

Four Domains. One Profile. One Decision.

This framework integrates dynamic balance, mobility, strength capacity, and movement quality into a unified classification model that drives clinical and performance decisions for basketball athletes. Test-agnostic, principle-based, and applicable across clinic, performance, and field settings.

Dynamic Balance & Reach

Multi-directional single-leg reach captures simultaneous demands on ankle, knee, and hip. Composite reach <94% of limb length carries 6.5× injury risk in HS basketball.

  • Anterior asymmetry >4 cm flag
  • Composite reach normalized to limb length
  • Posteromedial & posterolateral reach
↔

Mobility / ROM

Joint excursion required for sport mechanics. Restrictions don't just limit — they redistribute load to adjacent joints.

  • Ankle DF (knee-to-wall) target 9–11 cm
  • Hip IR/ER symmetry
  • Hamstring extensibility
◆

Strength & Force Capacity

Single-limb force production, sustained output, and absorption capacity. Bilateral testing systematically masks unilateral deficits.

  • Single-leg heel raise (norm ~25 reps)
  • 30-second sit-to-stand
  • Single-leg hop LSI
◇

Movement Quality

How force is produced and absorbed — the kinematic signature of stability strategy. Two athletes with identical strength scores can carry radically different injury risk.

  • Frontal Plane Projection Angle
  • Pelvic drop on single-leg squat
  • Compensatory pattern flags

Four Profile Archetypes

Mobility Deficit

Joint excursion is bottlenecking. Force is being redirected to adjacent joints.

Strength / Force Capacity Deficit

Owns positions and controls them — but cannot sustain or scale force under load.

Neuromuscular Control Deficit

Has resources but organizes them poorly. Strategy and motor-learning problem.

Mixed Profile

Two or more domains in deficit. Highest-risk pattern. Sequenced intervention required.

Domain 2 · Mobility / Range of Motion

Weight-bearing ankle DF (knee-to-wall, cm). Hip IR and ER (degrees, prone or seated). Hamstring active knee extension deficit (degrees from full extension).

Right Side
Left Side

Domain 3 · Strength & Force Capacity

Single-leg heel raise to failure (reps each side). 30-second sit-to-stand (total reps). Single-leg hop for distance (cm each side).
