Therapy-based expert system on function and postural stability after anterior cruciate ligament reconstruction: a...

Area of Science:

• Sports Medicine
• Rehabilitation Science
• Biomedical Engineering

Background:

• Anterior Cruciate Ligament Reconstruction (ACLR) rehabilitation often relies on conventional methods.
• The integration of exergames, such as Wii Fit, into post-ACLR recovery protocols is under-explored.
• Developing intelligent systems to guide rehabilitation programs can personalize patient care.

Purpose of the Study:

• To evaluate the efficacy of an expert system utilizing Wii Fit exergames for ACLR rehabilitation.
• To compare outcomes between Wii Fit exergames and conventional rehabilitation methods.
• To assess the impact of a rule-based expert system on exercise prescription for ACLR patients.

Main Methods:

• Twenty athletes (aged 20-30) who underwent ACLR were randomly assigned to two groups (n=10 each).
• One group received 12 sessions of Wii Fit exergames guided by an expert system.
• The control group received 12 sessions of conventional rehabilitation.

Main Results:

• Both groups showed significant improvements in pain, knee effusion, range of motion, thigh girth, hop tests, and balance.
• The Wii Fit group demonstrated statistically significant superior outcomes in pain reduction (VAS), knee effusion, thigh girth, and knee flexion.
• The Wii Fit group also showed significantly better results in static and dynamic balance tests and hop test symmetry indices.

Conclusions:

• Wii Fit exergames, guided by an expert system, offer a superior rehabilitation approach for post-ACLR athletes.
• This method effectively reduces pain and effusion while significantly enhancing knee function and balance.
• The study provides evidence for the potential of exergames in sports injury recovery.
