Table 5 Isometric muscle strength testing: protocol for child positioning, joint fixation, joint positioning and dynamometer resistance
Muscle group | Child position | Joint fixation | Joint starting position | Position of dynamometer resistance |
|---|---|---|---|---|
Knee extensors | Sitting | Pelvis and thigh | Knee flexed 90° | Anterior tibia, 5 cm proximal to malleoli |
Knee flexors | Sitting | Pelvis and thigh | Knee flexed 90° | Posterior calf, 5 cm proximal to malleoli |
Hip flexors | Sitting | Pelvis | Hip flexed off surface | Anterior thigh, 3 cm proximal to patella |
Hip abductors | Supine | Pelvis | Hip slightly flexed off surface using a knee roll | Lateral thigh, 5 cm proximal to the knee joint |
Ankle plantarflexors | Supine | Pelvis and lower leg | Hip flexed 90°, lower leg stabilized on a bench, ankle in neutral position. | Plantar surface of foot, across metatarsal heads |
