Table 4 Test modalities for isometric strength measures.
| Test mode and sequence | Position and fixation | Joint angle |
|---|---|---|
| 1. Hip abduction (HAB) |
• Recovery position (lateral) • Belts strapped around pelvis and contra-lateral leg | • 0° |
| 2. Hip adduction (HAD) |
• lower arm on the pillow, upper arm grasps the edge of the examination table • Tested leg in 90° knee flexion, fixed with orthosis | • 20° abduction |
| 3. Hip flexion (HF) |
• Supine position • Belts strapped around pelvis and contra-lateral leg | • 20° flexion |
| 4. Hip extension (HE) |
• Arms are folded • Tested leg in 0° knee flexion, fixed with orthosis | • 60° flexion |
