This study examines the effects of a 5-week program of neurofeedback combined with somatosensory exercises on balance and physical performance in older adults, with the goal of addressing age-related declines in sensory processing and motor function. Sixty older adult men with balance disorders were randomly assigned to one of three groups: neurofeedback combined with somatosensory training, somatosensory training alone, or a control group. The interventions were administered over 5 weeks, with participants attending three sessions per week. Assessments were conducted both before and after the intervention period, including measurements of static balance using the Stork test, dynamic balance using the Timed Up and Go (TUG) test, and physical performance using the Continuous Scale Physical Functional Performance-10 (CS-PFP-10) test. The findings revealed significant improvements in balance and physical performance among participants who received either neurofeedback combined with somatosensory training or somatosensory training alone. Specifically, the Stork test (with both open and closed eyes) showed significant increases in duration, while the TUG test indicated reductions in completion times for both intervention groups (p = 0.001), suggesting enhanced balance and mobility. Additionally, the CS-PFP-10 test results demonstrated a significant difference following the interventions (p = 0.001). These findings suggest that incorporating neurofeedback training into somatosensory exercises may provide additional benefits for older adults in improving balance and mobility.
