Muscle Strengthening Device for Knee Osteoarthritis
Osteoarthritic Knee Isometric Exerciser for Home Use
Study Overview
Detailed Description
Previous studies have shown that isometric strengthening is beneficial in managing osteoarthritis of the knee. This type of exercise can decrease joint-related pain and stiffness while increasing strength and functional measures. However, individuals rarely adhere to isometric exercise for any lengthy period of time because there has not been a way to measure applied force and performance over time in the home setting. In addition, this type of exercise has often been described as "boring." We believe that being able to monitor one's progress is essential in maintaining adherence to an isometric exercise program. This study will examine the effectiveness of a portable isometric exercise device for home use that guides the user through an exercise protocol by means of various forms of feedback.
We hypothesize that individuals exercising with the device will achieve better outcomes in pain, stiffness, strength, and functional measures than a control group or a group exercising according to printed material from arthritis advocacy groups. We will randomly assign study participants meeting eligibility criteria to the exercise device group, exercise according to printed material group, or control group. We will conduct measures in all groups during a clinic visit at baseline, 2, 4, 6, and 8 weeks. As subjects in the exercise device group strengthen their leg muscles, a physical therapist will likely need to adjust upward the target force for different leg positions during every clinic visit, 2 weeks apart.
