The Influence of Hip Strengthening Exercises on Walking Patterns & Muscle

Status Completed

Clinical Trial Summary

The purpose of this study is to determine the influence of a home program of exercises for the hip muscles which support the pelvis on walking patterns and hip muscle strength in people with knee osteoarthritis. Following a hip muscle strengthening program, we hypothesize that participants with knee osteoarthritis will demonstrate decreased loading at the knee joint during walking and greater strength of the hip muscles.

Clinical Trial Description

Knee osteoarthritis is a common age-related impairment that may progress to cause significant pain and physical disability. Excessive loading at the knee joint is believed to contribute to the progression of knee osteoarthritis. The hip joint and surrounding muscles have been shown to influence the amount of stress occurring at the knee joint during walking. In particular, the hip abductor muscles may have an effect on the knee joint by controlling the position of the pelvis and/or by acting as lateral stabilizers for the knee.

Research suggests that the function of the hip muscles during walking may be decreased in people with knee osteoarthritis and that greater loads may be placed on the knee joint as a result. Thus, interventions aimed at strengthening the hip abductor muscles may be effective for reducing stress on the arthritic knee and slowing the rate of progression of knee osteoarthritis.

The design of the study is a two-group pretest-posttest design using an untreated control group. Thirty-five individuals with medial compartment knee osteoarthritis will be recruited through newspaper advertisements and from the practices of orthopedic surgeons in Kingston, Ontario. Each participant with knee osteoarthritis will be matched with an asymptomatic volunteer for age (+/- 5 years), height (+/- 5 cm), mass (+/- 5 kg) and gender. Participants in the control group will have no clinical or radiographic diagnosis of knee or hip osteoarthritis or rheumatoid arthritis and no history of hip or knee trauma or pain. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
