Adherence and Feasibility of Remote Rehabilitation for Chronic Patellofemoral Joint Pain: a Randomized Controlled Trial

Sponsor

Peking University Third Hospital

Enrollment

63 participants

Start Date

Sep 10, 2023

Study Type

INTERVENTIONAL

Conditions

Patellofemoral Pain

Summary

This study is a prospective, single-center trial involving 66 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 measure was exercise adherence assessed using the Exercise Rating Scale (EARS) after 6 weeks of rehabilitation. Secondary outcomes included knee pain severity, muscle strength, knee function, fatigue levels, and a qualitative research questionnaire. An isokinetic strength testing system was used to measure the open-chain strength of the quadriceps muscle.

Eligibility

Inclusion Criteria5

(1) Anterior knee pain or retro-patellar pain caused by at least two of the following activities: prolonged sitting with knee flexion, bilateral squatting, ascending and descending stairs, kneeling, running, and jumping;
(2) presence of one of the following signs: patellar tenderness, friction pain, or twitching pain, positive single-leg squat test, or positive knee extension resistance test;
(3) knee pain lasting more than 3 months;
(4) knee pain score greater than 3 out of 10 on the VAS;
(5) unilateral pain and symptoms.

Exclusion Criteria7

(1) acute injury of the knee ligaments, joint capsule, bursa or meniscus;
(2) knee extension or flexion contracture deformity, thus being unable to perform normal lower limb flexion and extension;
(3) patellofemoral joint dislocation or subluxation;
(4) any traumatic, inflammatory or infectious disease of the lower limbs;
(5) a history of knee surgery;

Interventions

DEVICEone 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.

DEVICEThree 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.

DEVICESix 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.
