Training to reduce oxidative stress in knee OA

Official title: The Effect of Training on Oxidative Stress in Patients With Osteoarthritis of the Knee. A Study of the Effects of Supervised Exercise Therapy on Oxidative Stress.

Run by Vrije Universiteit Brussel · NCT07845838 · Data updated 2026-11-12

A six-week program compares supervised knee-strengthening training with a daily 6,000-step walking plan to see if it improves pain, function, and blood markers of cellular stress in people with knee osteoarthritis.

Is this trial a fit for you?

Likely a good fit

Adults with diagnosed knee osteoarthritis who can walk at least 6,000 steps per day.

Probably not a fit

Individuals unable to perform the 6,000-step walking requirement or participate in supervised training may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study tests whether 6 weeks of guided exercise or a walking-based routine can improve symptoms and daily-life function in knee osteoarthritis. Participants start with a screening blood sample and complete symptom questionnaires, with follow-up assessments after the training period. The trial involves two groups: one receiving supervised training twice weekly, and another walking 6,000 steps per day. Outcomes include pain scores, functional measures, and blood markers of oxidative stress. The goal is to determine if physical activity can strengthen knee muscles and enhance overall fitness in this population.

Why it matters

Potential benefit: If successful, participants may experience reduced pain and better knee function, with improved biomarkers of cellular stress.

How similar studies have gone: Previous research with exercise programs has shown benefits for knee OA, though this exact comparison of supervised training versus structured walking and its impact on oxidative stress is less established.
