چکیده
Functional electrical stimulation has been applied to restore the muscle activity of paralyzed patients who suffer from spinal cord injuries and related neural impairments for several decades. In this paper, a direct-synthesized arbitrary waveform stimulator for multichannel FES applications is described. A novel element-envelope method is proposed. A digital signal processor is chosen to synthesize required stimulating patterns with high time-resolution, and it preserves the ability to adjust stimulation parameters dynamically. Also, the system can provide bi-phasic, voltage-controlled constant-current patterns while remaining high-voltage compliance and wide bandwidth. The proposed stimulator can be considered as a full-featured stimulator for various FES applications with its flexibility in pattern generation and feedback processing capabilities.

متن کاملThe design of an embedded spinal cord stimulator
Spinal cord stimulation is a physical therapy methodology utilizing electrical impulses, pulses, or a combination of various standard electrical waveforms to block pain. However, standard forms are not functioning effectively for each illness due to the unique conditions of the patient. Therefore, patient-specific waveforms (or user-defined waveforms) integrated with nondestructive, complete, o...
