Effect of Video-based Game and Aerobic Exercise on Knee Osteoarthritis

The participants played the video game using an Xbox 360 Kinect console connected to a 55-inch Full HD television. The video games were planned with the assistance of a physiotherapist, 3 days per week, with 8 repetitions during the first 4 weeks and 12 repetitions during the final 4 weeks. The warm-up and cool-down periods were designed and applicated.

Aerobic exercise training was performed on a stationary bike, 3 days per week, for 20 minutes per session. The intensity of the aerobic exercise was determined using the Karvonen method. For the first 4 weeks, the intensity was set at 30-50% of the maximum heart rate (MHR), corresponding to light intensity, and was then increased to 50-70% (moderate intensity) for the following 4 weeks. A pulse oximeter (ChoiceMMed, China) was used to monitor the target heart rate. During both the warm-up and cool-down phases of the aerobic exercise, participants performed hip abduction and adduction, hip-knee flexion, heel raises, and mini squats while standing for 3-5 minutes.

Convetional treatment included Hotpack, Transcutaneous Electrical Nerve Stimulation (TENS), and Ultrasound (US) modalities, were applied to the symptomatic knee(s) for a total duration of 30 minutes. Following this, the exercise program outlined below was performed with 3 sets of 10 repetitions each. The session lasted approximately 45 minutes.
