Passive Range of Motion in degrees
Laxity and circumference measurements
Target: Delta ≤ 3mm
Circumference 4 inches above patella
Seated knee extension at 90° | Target: 1.0 ft·lb/lb BW
Prone knee flexion at 90° | Target: 0.6 ft·lb/lb BW
Side-lying hip abduction | Target: 0.65 ft·lb/lb BW
Side-lying hip adduction | Target: 0.8 ft·lb/lb BW
TTBW = Torque to Bodyweight: A conversion using limb length, bodyweight and force output to compare to normative data. Formula: τ = Force × (Distance × 3.28084) × sin(θ), then TTBW = τ / Bodyweight
Calf strength as percentage of bodyweight
Target: 1.5x Bodyweight
Endurance and motor control assessments
Reps in 30 seconds with 10% bodyweight external load to ~70° knee flexion
Target: >90% LSI
Reps to failure with fixed distance from hip to floor
Reps to failure - bottom hip taps floor, same foot taps bar each rep
Max reps in 30 seconds using 20% bodyweight and 12 inch box
Strength and power output comparison
Gross strength output without consideration of speed | Target: >90% LSI
Power (watts) when speed is controlled/constant | Target: >90% LSI
Dynamic balance assessment (reach distance in cm)
Target: >95% LSI
Jump testing and reactive strength
Total force from bottom of jump until leaving plates | Target: >90% symmetry
Peak speed from standing to bottom of jump | Target: 1.2 m/s
Target: 0.4 m/s
RSI (Reactive Strength Index): A measure of explosiveness, calculated by dividing jump height by ground contact time.
Change of direction and reactive agility
Resisted lateral bounding - 90 sec test, scored 5 pts per 30 sec | Target: 14/15
3 cone drill - lead hand/foot contact line each direction | Target: 4.5 sec
Forward sprint with 10yd entry, timing last 5yds | Target: <2.5 sec (Males), <2.8 sec (Females)
Testing Protocol: 3 attempts each direction with 2 min rest between attempts. Report best time.
