Context: Knee osteoarthritis (OA) is an important cause of pain and functional limitation in older people. Several short-term studies state that walking and resistance exercise reduce pain and disability and improve physical fitness in people with knee OA. Aims: To compare the effect of walking and resistance exercise on pain and function in older adults with knee OA. Materials and Methods: A quasi-experimental study was conducted at the physiotherapy department of General Hospital. Twenty one males and females in the age range of 60-75 years, diagnosed with knee OA by the orthopedic department according to the American College of Rheumatology criteria were randomly allocated into three groups. Conventional physiotherapy treatment remained common for all the groups. Group A subjects additionally walked at a self-paced speed. Group B subjects received resistance exercise for hip and knee muscles. Group C subjects received conventional physiotherapy treatment alone. Intervention was given 5 days/week for 2 weeks. Pain intensity at rest and during activity was assessed using visual analog scale (VAS) and physical function was assessed by Western Ontario McMasters Arthritic Index (WOMAC). The level of significance was set at 5%. Results: There was a significant difference in VAS at rest within group A and group B. The difference in VAS during activity and WOMAC scores was significant within each group. Mean difference in VAS during activity revealed a significant difference between group B and group A and between group B and group C. The mean difference in WOMAC scores was significant between group A and group C. Mean difference in VAS at rest showed no difference between the groups. Conclusion: Resistance exercises are more effective in reducing pain during activity and walking is more effective in improving physical function in older adults with knee OA.
