Influence of Virtual Reality Games on Knee Proprioception After Anterior Cruciate Ligament Reconstruction (ACLR)

Study Overview
=================
Brief Summary
-----------------
Influence of virtual reality games(Wii Fit) on knee proprioception after anterior cruciate ligament reconstruction (ACLR) will be measured in 30 postoperative patients. The age of participants will be ranged from 20 to 30 years old. Subjects will be randomly assigned to Group A is the study group and Group B is the control group.

Detailed Description
-----------------
Group A will receive the Wii fit protocol of virtual reality games, in addition to the regular exercise rehabilitation protocol, for 3 non-consecutive days per week, for 8 weeks , 40 minutes for each session. Group B will receive the regular exercise rehabilitation protocol only for 3 non-consecutive days per week for 8 weeks, 40 minutes for each session. A Universal Weight and Height Scale: will be used to measure the patient's BMI. Biodex Isokinetic Dynamometer: will be used to assess the knee proprioception of the affected operated leg at three target angles (30,45,and 60 degrees).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Group A: Study group<br>They will receive the Wii fit protocol of virtual reality games for 40 minutes, 3 times per week, for 8 weeks, in addition to the regular exercise rehabilitation protocol according to the criterion of Adams et al. (2012). | Procedure: Wii fit protocol of virtual reality games<br>* the Wii fit session by standing on the Wii fit board with bare feet, hands on hips and both eyes open. Pretest on Wii fit was done to make the subject familiar with the board and tasks of weight shift .<br>Procedure: Regular exercise rehabilitation protocol<br>* It will be according to the criterion of Adams et al. (2012).<br>|
| Experimental: Group B: Control group<br>They will receive the regular exercise rehabilitation protocol only for 40 minutes, for 3 days per week, for 8 weeks. | Procedure: Regular exercise rehabilitation protocol<br>* It will be according to the criterion of Adams et al. (2012).<br>|
