Corticospinal Excitability and Rehab in Knee Osteoarthritis

Knee Osteoarthritis Clinical Trial

Official title: Corticospinal Excitability and Rehab in Knee Osteoarthritis

Status Completed

Clinical Trial Summary

To determine differences in thigh muscle function in individuals with and without knee arthritis, and also determine the effectiveness of common physical therapy interventions on clinical and patient oriented outcomes.

Clinical Trial Description

The primary objective of the proposed research evaluates the concurrent changes in corticospinal excitability and central sensitization of pain pathways for their influence on quadriceps voluntary activation. A secondary objective is to establish the feasibility of an intervention study to determine if changes in the excitability of these supraspinal motor and sensory processes can be modified by physical therapy interventions targeting pain and muscle strengthening. We hypothesize that patients with knee osteoarthritis will show measurable deficits in quadriceps voluntary activation that can be explained by lower levels of corticospinal excitability and increased pain sensitization. A 1 week physical therapy intervention will improve voluntary activation and reduce pain with concurrent changes in underlying motor and sensory processes. We further hypothesize that part of this improvement will be attributed to positive treatment expectation. ;
