Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized controlled trial was conducted by the CONSORT guidelines for non-pharmacological treatments. Participants were randomly assigned to control, gaming, or aerobic groups using the closed-envelope randomization method. All groups received conventional physiotherapy for 8 weeks. In addition, the gaming group played active video games 3 days per week, while the aerobic group engaged in cycling-based aerobic exercise (20 minutes per session) 3 days per week. The control group received only conventional physiotherapy and continued their daily activities. Evaluations were performed by the same assessor at the baseline and after eight weeks.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Gaming

The gaming group played active video games via Xbox kinect 3 days per week, addition to conventional physiotherapy for 8 weeks.

Group Type EXPERIMENTAL

Active video game

Intervention Type OTHER

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.

Conventional treatment

Intervention Type OTHER

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.

Aerobic

The aerobic group engaged in cycling-based aerobic exercise (20 minutes per session) 3 days per week addition to conventional physiotherapy for 8 weeks.

Group Type EXPERIMENTAL

Aerobic exercise

Intervention Type OTHER

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.
