Effects of Corporal Visualisation Program of the Static and Dynamic Balance After an Operation of the LCA

Study Overview
=================
Brief Summary
-----------------
The aim of this pilot study is to assess the feasibility of a RCT whose topic would be the effect of a motor imagery program on the postural control in persons who have undergone ACL plasty.

Detailed Description
-----------------
Primary and secondary outcomes will be measured twice at the hospital, a first time six weeks after the beginning of the intervention and a second time eight weeks after the four weeks of the intervention. Twelves home-based motor imagery sessions will occur in four weeks, three times a week, to activate. The training sessions will last between 15 and 20 minutes. During each training session, the participant will note on his/her own Tracking sheet how long they listened to the audio and their comments. The Tracking sheet will document whether or not the patient has participated in each of the twelve sessions. In parallel, a control group will follow a placebo programme according to the same formalities. Twenty-three participants (min.) will take part in this study.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Motor Imagery Group A<br>This group will follow a program of motor imagery. | Other: Motor Imagery Program<br>* The intervention group of the study will undergo standard postoperative physical therapy treatment at their therapist. Beginning on the third day after surgery, the participant will begin an motor imagery program to be performed three times a week for four weeks. A session lasts between fifteen and twenty minutes. It begins with a body awareness phase followed by a series of three to five one-minute exercises to be repeated three times, with a one-minute break between each exercise. The program is performed independently at home using a standardized audio tape.<br>|
| Placebo Comparator: Motor Imagery Group B<br>This group will follow a placebo program inspired from Bodyscan | Other: Placebo program<br>* The control group of the study will undergo standard postoperative physiotherapy treatment at their therapist. On the third day after surgery, the participant will begin a relaxation program inspired by the mindfulness tool called Bodyscan that acts as a placebo mental imagery program. Nevertheless, the program created for this technique does not follow the Bodyscan guidelines (Jon Kabat-Zinn, 2005), as we do not want there to be any effects in favor of improved body perception on the participants, which could bring an additional biai to the study. For the sake of understanding, we have used the term body visualization in the various documents distributed to the participants. The program is to be performed three times a week for four weeks. A session lasts between ten and fifteen minutes. The program is performed independently at home using a standardized audio tape.<br>|
