Negative Work Exercise for the Treatment of Knee Arthritis

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to develop a negative work exercise regimen as an intervention for posttraumatic osteoarthritis (PTOA). "Negative work" is the force produced by muscles as they lengthen, and regularly occurs with common activities such as lowering an object from a shelf or walking down stairs. In this study, the investigators are examining the effectiveness of negative work exercise over a 12-week period in older, male, Veterans.

Clinical Trial Description

Purpose: To develop a negative work exercise regimen as an intervention for posttraumatic osteoarthritis (PTOA). Given that the medical management of chronic PTOA is similar to idiopathic OA, the investigators propose a randomized, clinical trial to pilot negative work exercise in Veterans with knee OA as a proof-of-concept study for a subsequent investigation for people with PTOA.

Research Setting: DC VAMC, Physical Medicine & Rehabilitation Laboratory

Participants: Men between the ages of 50 and 70 years with a history of bilateral knee osteoarthritis will be consecutively recruited from the DC VAMC Rheumatology Service, Geriatrics Service, and Primary Care Medical Service.

Implications/Significance: The use of negative work exercise to enhance the force attenuation properties of muscle is an innovative approach to the treatment of OA and PTOA, and represents a significant departure from previous rehabilitation studies concerning arthritis. Use of a negative work paradigm may prove to be beneficial for older Veterans with OA and active military personnel with PTOA since similar muscle mechanics are involved in the energy absorption at the knee joint during gait. Despite the functional importance of lengthening muscle actions in protecting weight-bearing joints affected by arthritis, the authors are not aware of a study that involves the sole use of a negative work intervention for OA or PTOA. Addressing the aims of this proposal would lay the ground work needed to justify larger clinical trials featuring the negative work paradigm for soldiers with PTOA. ;

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.
