Development of a Computer-assisted Foot Pressure Biofeedback Sensory Compensation System in Balance Control for Amputees

摘要: Sub-sensory electrical or mechanical stimulation can enhance the sensitivity of human somatosensory system to improve balance control capabilities elderly was shown in recent rehabilitation articles. In addition, clinical studies suggest that visual-auditory biofeedback sensory compensation for were reported. A computerized foot pressure using sub-threshold low-level combined with developed and proposed study. Three unilateral trans-tibial amputees who consecutively wore prosthetics over 10 years (13plusmn3.6) recruited this Experimental results show reduction all postural sway indices (constant time length, max distance average distance) increase single leg support index during quiet standing by applying sub-sensory stimulation. With providing clue heel contact toe push off condition treadmill ambulation, improvement four dynamic gait performance (double time, stance/swing ratio, constant cadence , sound side index) verified.
