Effects of a Perioperative Action Observation and Motor Imagery Training in Patients Undergoing Total Knee Arthroplasty

Not Applicable

• Conditions: Total Knee Arthoplasty
• Interventions: Behavioral: Usual care; Behavioral: Action observation and motor imagery

• Registration Number: NCT05459766
• Lead Sponsor: Istituto Clinico Humanitas

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.

Arm && Interventions

Group	Intervention	Description
CTRL	Usual care	Usual care, consisting of preoperative education.
AO+MI	Action observation and motor imagery	Video-clips observation representing motor contents, followed by motor imagery (12 minutes a day per 3 days).

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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
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
