Relevance – Strength curves have typically been measured with isometric and isokinetic dynamometers, which are expensive and cumbersome for clinicians.

Seated subjects performed 1 consecutive shoulder abduction-adduction movement while holding 1 kg dumbbell. Strength curve relative to shoulder abduction movement was assessed using wireless IMU fixed to upper arm.

Clinicians could easily apply this method in ambulatory settings and, hence, use it as routine diagnostic tool for assessing functional joint recovery.
