Insoles to improve balance
Wyss Institute and Boston University researchers have discovered that random vibrations, too gentle to be felt, can improve the sensory feedback system and may restore stability through a mechanism known as stochastic resonance. By incorporating vibrating elements in insoles and footwear, it has been shown that stochastic resonance improves balance and gait.
Mechanical actuators, designed to be inserted into any type of footwear, are embedded into the insoles. A signal generator and a small battery are also integrated within the insole to provide sensory enhancement stimulation to the user’s feet. A smart phone app controls the stimulation level and can inform the user of device status such as stimulation and battery levels.
When used by elderly individuals, this sensory enhancement insole could potentially improve their sense of balance and walking stability, which is understood clinically to be related to the risk of falling. For diabetics, who suffer from peripheral neuropathy, this kind of device may increase the sensitivity of their feet and might eventually decrease the risk of ulceration.
Researchers at Harvard University say this technology can modify gait to improve balance and even enhance agility for athletes
