Wireless-controlled portable peroneal stimulator

A microprocessor based peroneal nerve stimulator has been developed. Minimum required maintenance, ease of use and the compliance with EC requirements were the main design goals. To enhance versatility and accommodate the device to individual needs, the stimulator features three modes of operation regarding the trigger source and offers seven adjustable stimulation parameters, which can be set by the clinician via a PC computer or a simple external module. In addition to traditional use of foot-switches or other external switches to trigger the stimulation, a wireless RF link to the crutch mounted push-button gives the patient voluntary control over the timing of the stimulation. Cyclic stimulation is provided for training and muscle restrengthening. The stimulator is small, lightweight, battery operated and easy to use.
