Knee OA study: does doing two things at once change strength test results?
NCT ID NCT05893706
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 60 people with knee osteoarthritis to see if testing muscle strength while doing a second task (dual task) gives different results than testing strength alone. Participants were between 40 and 65 years old and had moderate knee OA. The researchers measured leg muscle strength, function, pain, and stiffness using standard tests and questionnaires.

Who is studied
A second assessment will be done 48 hours after the initial one. It will be completed as a dual job for the second evaluation. The patient will be given activities involving colors and numbers as part of the dual evaluation, and concurrently, after the isokinetic device has assessed the patient's muscle strength, the 30-second sit-and-stand test will assess the patient's function and balance.
