Ulsan University Hospital60 enrolled

Overview

It was well known that the mirror therapy could decrease pain of upper-limb amputated patients. The mirror therapy is known to make a plastic change some parts of the brain perceiving the painful body part and modulating its signal by feedback of visual information mirrored with the corresponding contra-lateral normal parts. In this study, post-operative analgesic efficiency of the virtual reality using a mirror therapy after total knee arthroplasty will be evaluated. This clinical trial will be performed in the form of prospective, single-blind (i.e. assessor-blind), parallel group, randomized (allocation ratio 1:1), single cohort.

Conditions

Osteoarthritis, Knee Nociceptive Pain Virtual Reality

Interventions

Patients are required to look at the images of both lower extremities ranged from the perineal area to the foot. Virtual reality system records in real-time method both lower extremities. Following the validity assessement mirrored image of the surgeried lower extremity is re-formed using the virtusal reality system flipping the image of lower extremity not-surgeried and being calibration for the symmetricity.

Outcomes

Primary Outcomes

6 minute walk test

The distance walked at a self-selected speed along a 40 cm corridor in 6 min. The distance was measured in meters, and more the meters better the result. A walking aid was used if needed.
