OsteoarthritisPhase 2NCT00007241
Muscle Strengthening Device for Knee Osteoarthritis
A Phase 2 study testing Isometric exercise in people with Osteoarthritis, run by National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at 6 sites in United States.
Trial summary
Studies have shown that isometric strengthening helps people with osteoarthritis of the knee. Isometric strengthening is muscle-strengthening exercise without movement, in which a person applies a force against a resistant object--for example, pushing against a brick wall.

About this study
Official title: Osteoarthritic Knee Isometric Exerciser for Home Use
Studies have shown that isometric strengthening helps people with osteoarthritis of the knee. Isometric strengthening is muscle-strengthening exercise without movement, in which a person applies a force against a resistant object--for example, pushing against a brick wall. This study will test the effectiveness of a portable isometric exercise device for home use that guides a person through an exercise program using various forms of feedback. We will look at whether people exercising with the device achieve better outcomes (results) in pain, stiffness, strength, and functional measures compared to people who do not use the device or people exercising according to printed material from arthritis organizations.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Isometric exercise in people with Osteoarthritis, run by National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at 6 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Jan 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00007241, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jan 2007.
