Development of vibrational foot orthoses by applying electrical noise-based technique with a stochastic resonance application

摘要

Diabetes Mellitus is a common disease which can cause peripheral neuropathy. Most diabetic peripheral neuropathic patients had impairment of the sensory nerve functions, especially tactile sensation. There are several studies revealed the effects of electrical noise or white noise with random resonance in maintaining the tactile perception in diabetic peripheral neuropathic patients. Our study aims to develop a low cost device for applying stochastic resonance in the form of a vibrating shoe insert. Afterwards we will use this device in our further study to justify the effect of this bespoke device for stimulation of tactile sensation in diabetic peripheral neuropathic patients with mild to moderate severity. The results of our study demonstrate that the device can generate low frequency (100 Hz) in a pattern of pseudo-random noise that will be applied with actuators which perform vibrations in the foot orthoses. In conclusion, we successfully developed a low cost device for applying stochastic resonance in the form of a vibrational foot orthosis.
