Brief summary
Osteoarthritis (OA) IS one of the most common joint disorders, affecting not only the joints but also the surrounding muscles, which become weak. Resistance exercise reduces pain and improves function in patients with OA of the knee. Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used by patients with OA to reduce pain and thereby maintain the ability to perform daily activities. However, there is accumulating evidence for a negative effect of NSAIDs, thus many patients with OA are treated with dietary supplementations such as glucosamine and chondroitin sulfate, and some studies show a beneficial effects on cartilage and pain. However, their effect on OA symptoms and cartilage remains controversial. Thus, it is important to investigate whether a potentially beneficial effect of glucosamine and chondroitin sulfate with resistance exercise and manual therapy in patients with knee OA.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analogue Scale | 2 weeks | Visual Analogue Scale was used to measure pain scoring from 0-10 cm on a horizontal 10cm line. A greater score reflects higher pain intensity. |
| Knee Injury and Osteoarthritis Outcome Score | 2 weeks | Knee Injury and Osteoarthritis Outcome Score (KOOS) to measure physical function and quality of life. A greater score on Knee Injury and Osteoarthritis Outcome Score reflects good prognosis and outcome and a lower score shows poor prognosis and outcome. the score for Knee Injury and Osteoarthritis Outcome Score is reported in the form of percentage i.e. 0-100%. |
| Knee Joint Range of Motion | 2 weeks | Knee Joint Range of Motion will be measured via goniometry. It is a continuous scale and a greater score reflects greater angular movement possible at the knee joint, which is measured in degrees. |
| Body Composition | 2 weeks | Body Composition was measured via bioelectrical impedance analysis. A greater Phase angle reflects better cellular integrity and smaller phase angle reflects poorer cellular integrity. |
| Fall risk | 2 weeks | Fall risk will be measured via Biodex balance system, and greater score reflects greater fall risk and poorer outcome. |
| 5 repetition sit to stand test | 2 weeks | Time will be measured to perform 5 repetitions of sit to stand activity. Lesser time means a better score. |
| Modified sphygmomanometer dynamometry | 2 weeks | Modified sphygmomanometer dynamometry was used to measure muscle strength. Greater score will reflect greater muscle strength. The unit of Modified sphygmomanometer dynamometry used will be mmHg (millimeter of mercury). |
