Ambulatory assessment of shoulder abduction strength curve using a single wearable inertial sensor. J Rehabil Res Dev. 2015;52(2):XX–XX. Slideshow Project DOI: /JRRD JSP Aim – Assess reliability of using a single inertial measurement unit (IMU) for determining strength curves during isoinertial exercises. Relevance – Strength curves have typically been measured with isometric and isokinetic dynamometers, which are expensive and cumbersome for clinicians.

Ambulatory assessment of shoulder abduction strength curve using a single wearable inertial sensor. J Rehabil Res Dev. 2015;52(2):XX–XX. Slideshow Project DOI: /JRRD JSP Method 45 men and women without previous/current shoulder impairment and not involved in professional sports participated. 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.

Ambulatory assessment of shoulder abduction strength curve using a single wearable inertial sensor. J Rehabil Res Dev. 2015;52(2):XX–XX. Slideshow Project DOI: /JRRD JSP Results High intraclass correlation coefficient values for range of motion and angular velocity. – Indicates high within-subject repeatability of task. High waveform similarity of torque curves between trials. With respect to isokinetic dynamometer, high IMU accuracy in estimating range of motion. – Error always <1 .

Ambulatory assessment of shoulder abduction strength curve using a single wearable inertial sensor. J Rehabil Res Dev. 2015;52(2):XX–XX. Slideshow Project DOI: /JRRD JSP Conclusion A single wearable IMU can effectively assess strength curves during isoinertial movements. Clinicians could easily apply this method in ambulatory settings and, hence, use it as routine diagnostic tool for assessing functional joint recovery.
