About

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.

Enrollment: 60 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• patients who were transferred to RM after unilateral TKA

Exclusion criteria

• patients cannot freely move the contralat. leg d/t neurologic or musculoskeletal problems
• patients are not enough clear to indicate VAS
• patients cannot look at the virtual reality monitor d/t visual problem
• refusal of the participation
