Effect of a Village Doctor-delivered Exercise Therapy for Knee Osteoarthritis

2026년 6월 4일 업데이트: Guanghua Lei, Xiangya Hospital of Central South University

Effect of a Village Doctor-delivered Exercise Therapy for Knee Osteoarthritis: a Pilot Feasibility Study

The goal of this clinical trial is to test the feasibility of village doctor-delivered exercise therapy for knee osteoarthritis in rural China, and to preliminarily explore its treatment effects. The main questions it aims to answer are:

  1. Is the exercise therapy delivered by village doctors feasible with satisfactory participant adherence?
  2. Can this intervention produce preliminary benefits in this small pilot sample? Researchers will compare village doctor-delivered exercise therapy to usual care to see if the intervention leads to greater pain relief and functional improvement in this pilot study.

Participants will complete village-delivered exercise therapy three times a week for 12 weeks, then maintain independent exercise for another 12 weeks or receive usual care for a total of 24 weeks.

실험적: Village doctor-delivered exercise
Participants allocated to the intervention group will receive village doctor-delivered exercise therapy.
행동: Exercise
The village doctor-delivered exercise program will be conducted over 12 weeks, with participants engaging in three sessions per week, each lasting approximately 50 minutes. To prevent excessive fatigue, each session will be scheduled with at least a one-day interval. Each session will consist of three phases: a warm-up phase, an exercise phase, and a cool-down phase. Following the 12-week exercise program supervised by village doctors, participants in the intervention group will be encouraged by researchers and village doctors to continue the exercise program without supervision until the 24-week follow-up.
가짜 비교기: Usual care
Participants allocated to the control group will receive usual care, which means treat their knee condition as usual.
행동: Usual Care
Participants will seek medical attention and address their knee pain issues according to their past habits, but should not increase the use of previously unused treatment methods or adopt invasive treatment methods during the study period.

기간: From baseline to 12-week follow-up
Changes in grip strength from baseline to 12-week follow-up. Grip strength is measured using a calibrated JAMAR hydraulic hand dynamometer (Lafayette Instruments). Participants are positioned sitting upright in a stable four-legged chair (no armrests) with thighs horizontal and at 90°. The assessed arm is bent with the upper arm vertical, lower arm horizontal, elbow tight into the waist and the non-assessed arm placed relaxed in their lap. Three measurements are taken at 10-second intervals for each hand and the averaged value of the three measurements is used as the final grip strength for each hand
From baseline to 12-week follow-up
Quadriceps muscle strength
기간: From baseline to 12-week follow-up
Changes in quadriceps muscle strength from baseline to 12-week follow-up. The maximum voluntary quadriceps contraction is assessed for each participant in a standard fashion using the 'Nicholas Manual Muscle Tester' (Lafayette Instruments). The participant is positioned sitting upright on a stable flat surface (no arm rests) with thighs horizontal and knees at 90° flexion. The instrument is then positioned at the bottom of the participant's tibia just above the ankle and they are asked to push against it as hard as possible in an attempt to raise their lower leg forwards, with resistance provided by the research metrologist. This is carried out three times on each leg and the mean value for each side is recorded
From baseline to 12-week follow-up
Hamstring muscle strength
기간: From baseline to 12-week follow-up
Changes in hamstring muscle strength from baseline to 12-week follow-up. The maximum voluntary hamstrings muscle strength is assessed for each participant in a standard fashion using the 'Nicholas Manual Muscle Tester' (Lafayette Instruments). Participants are tested in prone for three repetitions with the test knee at 90° flexion and with the dynamometer placed immediately proximal to the level of the prominence of the lateral malleolus. Tests are performed alternating between the dominant and non-dominant limb. The mean value of three testing for each side is recorded
From baseline to 12-week follow-up
Quantitative sensory testing (QST)
기간: From baseline to 12-week follow-up
Changes in QST from baseline to 12-week follow-up. Pressure pain threshold (PPT) is assessed to represent quantitative sensory. An algometer (1 cm2 rubber tip; Wagner, FDIX25) is applied at a rate of 0.5 kg/second on each anatomical site and determining the point at which participants verbally indicated the pressure first changed to slight pain. Participants are familiarised before testing by twice PPT testing on sternal notch. The PPT testing is conducted at 9 sites: sternum (3-cm caudal to the sternal notch), the medial and lateral tibiofemoral joint lines adjacent to the patellar ligament of each knee, the proximal tibia (5-cm distal to the tibial tuberosity of each leg), and the centre of the patella
From baseline to 12-week follow-up
Hip abductor muscle strength
기간: From baseline to 12-week follow-up
Changes in hip abductor muscle strength from baseline to 12-week follow-up. The maximum voluntary hip abductor muscle contraction is assessed for each participant in a standard fashion using the 'Nicholas Manual Muscle Tester' (Lafayette Instruments). The participant is positioned on a clinic couch lying on their side with the lower leg bent for stability and the upper leg out straight. The instrument is then positioned above the lateral condyle of femur and the participant are asked to push against it as hard as possible in an attempt to raise their leg up towards the ceiling with resistance provided by the researcher. This is carried out three times on each leg and the mean value for each side is recorded
From baseline to 12-week follow-up
Appendicular skeletal muscle mass
기간: From baseline to 12-week follow-up
Changes in appendicular skeletal muscle mass from baseline to 12-week follow-up. The participant had their appendicular skeletal muscle mass measured using bioimpedance analyses (InBody 770 analyser, InBody Japan, Tokyo, Japan). With bare feet, the participants are instructed to stand with heel and forefoot placed on the metal plates of the instrument and grab the handle. A sub-threshold electrical current is then transmitted through the body from foot to foot. The impedance-based appendicular skeletal muscle mass is determined as per the manufacturer's imbedded equations
