Video Game-Based Electromyographic Biofeedback Interventions in Patients With Knee Osteoarthritis: A Clinical Trial

Area of Science:

• Orthopedics
• Rehabilitation Medicine
• Digital Health

Background:

• Knee osteoarthritis (OA) significantly impacts pain and mobility.
• Exercise is a primary non-drug treatment for knee OA.
• The study evaluated a novel biofeedback game for knee OA rehabilitation.

Purpose of the Study:

• To compare the efficacy of the Knee Biofeedback Rehabilitation Game for Osteoarthritis Therapy (KneeBRIGHT) with traditional exercises.
• To assess improvements in quadriceps strength, knee function, and balance in knee OA patients.
• To explore patient motivation and adherence to rehabilitation programs.

Main Methods:

• A 10-week randomized controlled trial with parallel, prospective, single-blind design.
• Participants were divided into KneeBRIGHT (n=17) and control (n=17) groups.
• Outcome measures included quadriceps strength, KOOS, IKDC, and balance, assessed pre- and post-intervention.

Main Results:

• The KneeBRIGHT group showed significant improvement in KOOS quality of life (QOL).
• The control group improved in KOOS symptoms, pain, ADL, sports, and QOL.
• Interviews revealed KneeBRIGHT games enhance motivation and serve as an effective exercise alternative.

Conclusions:

• KneeBRIGHT games improved perceived knee function and quadriceps strength compared to traditional exercises.
• Gamified rehabilitation can enhance patient motivation and independent home-based exercise adherence.
• Biofeedback gaming presents a promising adjunct for knee OA therapy.
