Group workout may ease knee arthritis symptoms
NCT ID NCT07073911
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a 12-week group exercise program called Les Mills Thrive can change how muscles work and improve strength, balance, and symptoms in 42 older adults with knee osteoarthritis. Participants will attend weekly classes that include flexibility, strength, and coordination exercises. Researchers will measure muscle activity, balance, and symptom changes before and after the program.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Les Mills Thrive group exercise class
- What this could lead to
- If it works, this could point toward a simple, group-based exercise program to help manage knee osteoarthritis symptoms and improve mobility.
- What could go wrong
- This is a small, early-stage study with no control group, so results may not be generalizable. The exercise may not change muscle activation patterns or symptoms for everyone.

Inclusion Criteria: * Participants must have received a diagnosis of knee OA from a physician and/or meet the American College of Rheumatology Clinical Classification Criteria for Osteoarthritis of the knee. The American College of Rheumatology criteria specify that a participant needs to have pain and fulfill three of the following six items: 1) aged 50 years or older, 2) no early morning stiffness or morning stiffness less than 30 minutes, 3) crepitus, 4) bony tenderness, 5) bony enlargement, 6) no palpable warmth * They must pass the Get Active Questionnaire to ensure that they are safe to begin an exercise program (determined via recruitment email). Exclusion Criteria: * i) severe knee trauma, knee surgery, or intraarticular knee joint injections in the previous six months, ii) active synovitis, iii) concurrent neurological (i.e. Parkinson's disease, Alzheimer's dementia, or polyneuropathy), endocrine (i.e., diabetes mellitus) and/or vestibular disorders which may affect balance, iv) chronic disease that may put them at risk during the exercise classes (i.e., history of heart failure, stroke, chronic obstructive lung disease), v) uncorrected visual impairment which may affect balance, or vi) an inflammatory rheumatic disease (i.e., rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and chronic reactive arthritis).
