adaptation and validation of the exercise adherence rating scale of knee osteoarthritis patients (gonears)

Conditions: Knee Osteoarthritis

Summary: the origin of knee osteoarthritis is multifactorial but the disease is strongly related to age. the pain and functional disability are the main reasons for consultation. non-pharmaceutical treatment is always indicated. the rehabilitation will reduce the pain, maintain or partially recover the amplitude of the movements as well as fight against vicious analgesic attitudes and strengthen the muscles to stabilize the joints. a program of self-rehabilitation exercises performed at home may be prescribed to people with knee osteoarthritis. it must include exercises adapted to the patient's functional abilities and painful level and requires education to improve the patient's motivation to practice a regular exercise program. however, adherence to such exercises is low, and until 2016 there was no objective way to find out the reasons for patients' lack of adherence to self-workout programs. the ears ("exercise adherence rating scale" or adhesion to physical exercise programs) is validated in 2016 and reliable to evaluate the physical activity of patients with low back pain. as far as we know, this questionnaire is the only one validated in the international literature, a validation for french patients is currently underway. we believe this tool can be used for patients with knee osteoarthritis after minor changes.

ears ("exercise adherence rating scale" or adhesion to physical exercise programs) assesses in the first part what type of physical exercise was recommended for patients with common chronic pain, as well as their frequencies and the date until which they were prescribed. the patient can also inform how often he can do his exercises, or otherwise, if he has completely stopped them, to mention since when and why. a second part of the questionnaire explores the behavior of patients towards adherence to exercise programs and a final part examines the reasons for or not performing these exercises. inclusion and the first questionnaires period at the beginning of the knee rehabilitation program (program for 6 weeks). clinical and demographic data questionnaire that will be completed by the investigating physician. the second questionnaire will be done at 48 hours from the inclusion (only the ears questionnaire will be filled at 2 days). the third time the patients will complete the questionnaires at the end of the rehabilitation program and the last time at 4 months end half.
