Mobile-Based Telerehabilitation With Sensors for Adherence and Efficacy in Chronic Patellofemoral Pain: A Randomized Controlled Trial
Sponsor: Peking University Third Hospital
Summary
This study is a prospective, single-center trial involving 174 patients diagnosed with patellofemoral pain. The study adhered to ethical guidelines and obtained informed consent from all participants. Participants were randomly assigned to receive face-to-face remote rehabilitation guidance either 1 time, 3 times, or 6 times. The primary outcome was device-recorded training adherence, defined as cumulative total training time (hours) and mean weekly training time (hours/week) over the first 6 weeks of independent home-based telerehabilitation.Self-reported adherence was measured using the Exercise Adherence Rating Scale (EARS) at week 6 (i.e., 6 weeks after the participant completed their final face-to-face tutorial).ain intensity during daily activities and squatting at 60° was measured using the Visual Analog Scale (VAS; 0-10);7 quadriceps muscle strength (concentric and eccentric peak torque) was evaluated using isokinetic dynamometry; knee function was assessed with the Kujala Patellofemoral Score (0-100); fatigue was measured using the Fatigue Severity Scale (FSS; 9 items, 7 points each). Additionally, a closed-ended adherence survey captured participant perceptions of factors influencing adherence

Interventions
one session of face-to-face telerehabilitation tutorial (OST)
The first group participated in a face-to-face tele-rehabilitation session in the hospital on the use of sensors and rehabilitation software before the home-rehabilitation session. Thereafter, the tele-rehabilitation program included muscle strengthening, flexibility stretching, and movement quality training every Tuesday, Thursday, and Saturday.
Three session of face-to-face telerehabilitation tutorials (TST)
The second group participated in three face-to-face tele-rehabilitation sessions in the hospital on the use of sensors and rehabilitation software before the home-rehabilitation session. Thereafter, the tele-rehabilitation program included muscle strengthening, flexibility stretching, and movement quality training every Tuesday, Thursday, and Saturday.
Six session of face-to-face telerehabilitation tutorials (SST)
The third group participated in six face-to-face tele-rehabilitation sessions in the hospital on the use of sensors and rehabilitation software before the home-rehabilitation session. Thereafter, the tele-rehabilitation program included muscle strengthening, flexibility stretching, and movement quality training every Tuesday, Thursday, and Saturday.
