Participants in the experimental group engaged in a home-based exergame program for 50 minutes per session, three times per week, for eight weeks. The program focused on enhancing lower extremity strength and balance.

The control group participated in weekly online education sessions for 50 minutes over an eight-week period. The topics covered included fall prevention, musculoskeletal health, aging, and fracture risks. No physical exercise intervention was given.

The home-based exergame program was conducted using the Nintendo Switch and Ring Fit Adventure program at participants' homes. The program included a 10-minute warm-up, 30 minutes of main exercise, and a 10-minute cool-down, lasting a total of 50 minutes per session. Sessions were held three times per week for eight weeks. The exercises targeted lower extremity strength, balance, and flexibility and included yoga, leg exercises (e.g., squats, knee lifts), and other activities performed in a gamified virtual environment. Participants received guidance on using the console, and family members were involved to support proper execution of the exercises.

The one-leg standing test was used to evaluate static postural balance. The one-leg standing test is a simple, reliable, and valid test for assessing balance and fall risk in older adults.

To evaluate dynamic postural balance, the Berg balance scale was used. It has a perfect score of 56 and consists of 14 items, with a perfect score of 4 for each item.

Functional reaching test was used to evaluate movement limits.

Timed up-and-go test was used to assess functional movement and mobility.

Five-times sit-to-stand test was used to evaluate lower-extremity muscle strength.

Falls efficacy was evaluated using the Modified Falls Efficacy Scale (MFES), which was specifically developed for older adults. The MFES consists of 14 questions, each scored from 0 (not confident) to 10 (very confident). The total score ranges from 0 to 140, with higher scores indicating greater confidence in performing activities without falling, which is considered a better outcome.
