Wearable motion sensor device to facilitate rehabilitation program in patients with shoulder adhesive capsulitis: a pilot study to assess feasibility
ABSTRACT
Background:
Adhesive capsulitis (AC) of the shoulder is a common shoulder disorder that painfully reduces the shoulder range of motion (ROM) among the middle-aged population. Although physical therapy with home-based exercises is widely advised to restore range of motion in the treatment of AC, clinical results vary owing to inconsistent compliance.
Objective:
This study aims to verify the feasibility of a treatment model that applies wearable motion sensor device (MSD) to assist home-based exercises to improve training compliance and the accuracy of exercises, with the ultimate goal of improving the functional recovery of AC patients.
Methods:
The MSD comprised inertial measurement unit-based sensors and mobile apps for patients and physicians, offering shoulder mobility tracing, home-based exercise support and progress monitoring. The inter-rater reliability of shoulder mobility measurement using the MSD on ten healthy participants and 15 AC patients was obtained using intraclass correlation coefficient (ICC) analysis and compared to assessments by two highly experienced physicians. A pilot prospective control trial was then carried out to allocate 15 AC patients to two groups – a home-based exercise (HE) group and a motion sensor-assisted rehabilitation (MAR) group. Changes in active and passive shoulder ROM, pain and functional scores and exercise completion rates were compared between groups for a treatment of three months.
Results:
Shoulder ROM, as measured using the MSD herein, exhibited good to excellent reliability by comparison the measurements made by two physicians (ICC range from 0.771 to 0.979). The AC patients in the MAR group exhibited better shoulder mobility and functional recovery and a higher exercise completion rate than the patients in the HE group during and after three months of rehabilitation
Conclusions:
This investigation shows that MSD-assisted home-based rehabilitation in the treatment of AC is a useful treatment model for tele-rehabilitation that enhances the compliance of patients with training, improving functional recovery, the overcoming of important obstacles in physiotherapy at home by providing comprehensible and easily accessible exercise instructions, compliance, exercise correctness, and the monitoring of progress.
