Study Overview
Brief Summary
The goal of this clinical trial is to compare effects of retro walking exercise versus forward walking using lower body positive pressure on knee pain, physical function, and quadriceps muscle strength in people with mild to moderate knee OA. The secondary aim is to compare effects of retro walking exercise versus forward walking using lower body positive pressure on mobility function, balance, and self-reported health outcomes in people with mild to moderate knee OA. The main questions it aims to answer are:
- Does retro walking exercise improve knee pain, physical function and Quadriceps muscle strength compared to forward walking exercise using lower body positive pressure in people with mild to moderate knee osteoarthritis?
- Does retro walking exercise improve Mobility function, balance, and self-reported health outcomes compared to forward walking exercise using lower body positive pressure in people with mild to moderate knee osteoarthritis?
Participants will walk (retro versus forward) on a lower body positive pressure treadmill.
If there is a comparison group: Researchers will compare [retro walking compares to forward walking] to see if [improve in knee pain, physical function, and quadriceps muscles strength]

Outcomes
Primary Outcomes
Thigh muscle strength test
Time Frame: Change from baseline thigh muscle strength at 6 weeks.
A Biodex isokinetic dynamometer (Model 4Pro) connected to a computer will be used to assess bilateral knee's flexor and extensor isometric muscle strength.
Numeric pain rating scale
Time Frame: Change from baseline pain at 6 weeks
The NPRS is an 11-point scale with "0" representing "no pain" and "10" representing "most imaginable pain" used to assess pain intensity.
Knee injury and osteoarthritis outcome score (KOOS)
Time Frame: Change from baseline pain, symptoms, and level of disability at 6 weeks.
The KOOS is a self-reported, knee-specific questionnaire that is aimed to measure knee pain, symptoms, and level of disability during the last week.
Secondary Outcomes
- Functional reach test(Change from baseline static balance at six weeks)
- Patient Health Questionnaire -9(Change from baseline depression at six week)
- 10-Meter Walk Test(Change from baseline walking speed at six weeks)
- Rapid Assessment of Physical Activity(Change from baseline physical activity at six week)
- 4 square step test(Change from baseline dynamic balance and coordination at six weeks)
- 6 minute walk test(Change from baseline aerobic capacity and endurance at six week)
- Five times sit to stand test(Change from baseline balance at 6 weeks.)
- 3-M Backward Walk Test(Change from baseline backward walking at six weeks.)
- Timed up and go test(Change from baseline Functional mobility at six weeks.)
- Medical Outcomes Study Short Form 12 (SF-12)(Change from baseline quality of life at six weeks)
