Poster 198: Forward flexion can reliably be measured with a front-facing camera used for at-home physical therapy

Objectives: Accurate assessment of shoulder range motion (ROM) is important for both initial evaluation and evaluating rehabilitation progress. Recently, digital platforms have been developed which assess ROM with the use a front-facing camera available on smartphones. Such tools allow to be objectively assessed monitored remotely but require validation. The purpose this study was, therefore, compare forward flexion (FF) measured health platform (PT Genie, Orlando, Fl) ( Figure 1) in-office measurements hand-held goniometer (Halo Medical Devices, Australia) 2) Methods: A prospective was performed consecutive patients evaluated in single specialist practice. Thirty -two patients, including 16 males females, aged 58.5 ± 17.4 years (range 24-80) participated study. All participants completed 3 FF efforts first goniometer, followed by camera. were recorded same examiner. using obtained an iPhone 11 running iOS 15.4.1, PT Genie 1). mean from calculated differences between two measurement options then compared simple Student t- test. Analysis SPSS version 17 (SPSS Inc., Chicago). Results: For groups there no significant within (p > 0.05). Mean 120.1° 24.7° 71.7° - 164.7°) 123.5° 26.0° 74.7° – 173.0°) front- facing camera, difference 3.4° (p<0.001). Conclusions: These findings suggest that comparable While small seen methods, are not likely clinically relevant, more importantly, internally consistent. preliminary help establishing such application remote physical therapy. Further needed other planes obtain data larger cohort.
