Total Knee Arthoplasty
Conditions
Brief summary
The study is aimed at investigating the effects of action observation and motor imagery training in patients undergoing total knee arthroplasty. Fifty participants will be enrolled during hospital admission and randomized into 2 groups (AO+MI and CTRL groups). AO+MI will undergo 12-minute AO+MI intervention for 3 days (preoperative day, first and second postoperartive days), whereas CTRL group will undergo usual care. At baseline, first and third postoperative days, participants will be assessed for mobility, pain, range of motion, quadriceps acrivation failure and patient's bady-pain representation by a blinded operator.
Interventions
BEHAVIORALUsual care
Participants will be educated about the postoperative rehabilitation program
BEHAVIORALAction observation and motor imagery
Observation and imagination of functional tasks that will be performed during the postoperative rehabilitation program.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in functional mobility | At baseline, at 1 day and 3 days after surgery | It will be assessed using the Timed Up and Go test |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in active and passive knee range of motion | At baseline, at 1 day and 3 days after surgery | It will be assessed using an inertial measurement unit |
| Changes in perceived pain | At baseline and 3 days after surgery | It will be assessed using Numerical Rating Scale (0-10 points), where 0 means no pain and 10 means maximum pain. |
| Changes in body pain representation at the level of the knee joint | At baseline and 3 days after surgery | It will be assessed using the Pain Drawing Body Chart |
| Changes in quadriceps activation failure | At baseline, at 1 day and 3 days after surgery | It will be assessed using the Quadricpes Activation Battery |
