Biofeedback Balance Exercises in Parkinson's Disease

Biofeedback system is a center of pressure-controlled video game-based exercise system designed for patients with neurological and orthopedic diseases and provides balance training using auditory, visual, and pressure biofeedback. The system contains several games, each designed to focus on a different component of balance. Biofeedback is provided by means of a monitor in front of the patient. The balance exercises program was involved a total of 18 sessions, each lasting 20 min, three times a week for six weeks, and was individually tailored based on the patient's tolerance and current motor and sensorial capacities. All patients performed conventional exercises.

Classic balance exercises were performed (two-leg stance, semi-tandem stance, tandem stance, standing on one leg, tandem walking, turning completely around, heel-to-toe stance, and standing with the eyes closed). Patients with balance disorder first could be commenced balance training in a seated position before progressing to standing exercises, to the extent that these could be tolerable.
