Summary

Based on the purpose of this study, the following hypotheses were established:

There will be a significant difference in balance changes within and between groups following balance training with progressive intermittent visual occlusions compared to general balance training.

There will be a significant difference in instability changes within and between groups following balance training with progressive intermittent visual occlusions compared to general balance training.

There will be a significant difference in muscle strength changes within and between groups following balance training with progressive intermittent visual occlusions compared to general balance training.

There will be a significant difference in functional performance changes within and between groups following balance training with progressive intermittent visual occlusions compared to general balance training.

BIOLOGICAL

Balance Training with Stroboscopic Glasses

The difficulty level of intermittent visual occlusion was structured from Level 1 to Level 8 based on frequency. As the flicker speed of the lenses decreased and the frequency lowered, the difficulty increased. For example, a setting of 6 Hz means the lenses flicker six times per second, whereas 1 Hz indicates one flicker per second. Levels 1 to 5 are suitable for dynamic movements such as catching or hitting a ball, while Levels 3 to 8 are appropriate for balance and proprioceptive training. In this study, participants wore stroboscopic glasses (Senaptec Strobe, Senaptec, USA, 2016) and began at Level 1 (6 Hz). The difficulty was gradually increased each week, with the setting adjusted to Level 3 (4 Hz) in Week 2, Level 4 (3 Hz) in Week 3, and Level 5 (2.25 Hz) in Week 4 (see Table 5). The training was conducted using the standard Mode A, in which both lenses flicker simultaneously.

BIOLOGICAL

Balance Training without Glasses

The exercise program consisted of six types of exercises and was conducted in a 30-minute circuit training format repeated twice per session. Participants took part in two sessions per week for four weeks, totaling eight sessions. The six exercises were completed as a circuit, repeated twice per session. A 30-second rest was provided between exercises and a 2-minute rest between circuits. All exercises were conducted by a licensed physical therapist to ensure safety.
