ANTERIOR
Anterior Cruciate Ligament (ACL) plays a crucial role in proper knee function and stability [Wii Fit™ is an exergaming video game released by Nintendo Wii™(Nintendo Co Ltd, Kyoto, Japan) with 48 exergames [The Nintendo Wii Balance Board (NWBB) is a unique accessory for the Wii console designed to train and also evaluate the center of balance [In the review of the use of NWBB in ACL rehabilitation, Karakoc et al. found no significant differences in pain, functionality, and balance between Wii Fit and control groups [Expert System (ES) has recently been introduced in rehabilitation with the capacity to replace the specialist. ES is used to solve problems with explicit knowledge but without any special algorithm [This research has focused on developing an ES for providing a rehabilitation program using NWBB exergames compared to the conventional rehabilitation on balance and physical function of ACL-reconstructed athletes.In summary, this study aims to develop an expert system (ES) for ACL rehabilitation using the Nintendo Wii Balance Board (NWBB) exergames and compare its effectiveness with conventional rehabilitation methods on ACL-reconstructed athletes' balance and physical function. The current literature suggests that the use of NWBB without an ES may not result in significant differences in rehabilitation outcomes compared to conventional methods. This study's original and innovative aspect is the development of an ES for ACL rehabilitation using NWBB exergames, which has not been extensively studied in physiotherapy. The study will enroll 20 ACL-reconstructed athletes, randomly assigned into two groups, one using the ES-based Wii Fit exergames program and the other using conventional rehabilitation. The study's outcomes will include pain, knee effusion, knee flexion range, thigh circumference, and single-leg hop for distance and time, as well as static and dynamic balance tests. The results of this study may contribute to improving ACL rehabilitation outcomes and provide a new approach to physiotherapy rehabilitation.
