| Summary: | A spinal cord injury (SCI) has a severe impact on human life in general as well as on the physical status
and condition. The use of electrical signals to restore the function of paralyzed muscles is called functional
electrical stimulation (FES). FES is a promising way to restore mobility to SCI by applying low-level electrical
current to the paralyzed muscles so as to enhance that person’s ability to function and live independently.
However, due to the limited number of commercially available FES assisted exerciser systems and their rather high
cost, the conventional devices are unaffordable for most peoples. It is also inconvenient because of wired based
system that creates a limitation in performing exercise. Thus, this project is concerned with the development of
low-cost current controlled stimulator mainly for the paraplegic subjects. The developed device is based on a
microcontroller, wireless based system using Zigbee module, voltage-to-current converter circuit and should
produce proper monopolar and bipolar current pulses, pulse trains, arbitrary current waveforms, and a trigger
output for FES applications. This device has been developed as in the new technique of the stimulator development
with low cost and one of the contributing factors in Rehabilitation Engineering for patients with SCI. |
