Functional Electrical Stimulation

Artificial Life and Robotics, 2000
If a motor nerve is stimulated from an external electrode, the resulting action potential will propagate to the innervated muscle and a twitch will be produced. The muscle responds to the artificially initiated nerve signal just as it would a naturally occurring signal.

Functional electrical stimulation

Physiological Measurement, 1997
In the health-care professions, electrical stimulation is used for three purposes: to aid diagnosis; as a therapeutic tool; and to restore lost or damaged functions. Functional electrical stimulation (FES) and functional neurostimulation (FNS) are terms which are more or less interchangeable, and which encompass the third of these purposes.

Neuromodulation for Functional Electrical Stimulation

Physical Medicine and Rehabilitation Clinics of North America, 2019
This article describes the application of neuromodulation in different ways to motor recovery, to replace lost function, or to improve function of organ systems for those who have experienced spinal cord injury or stroke. Multiple devices have been developed and are currently available for use whereas others are still in the experimental stage ...

Functional Electrical Stimulation

2021
The activation of excitable biological tissues such as nerves and muscles by external electrical stimulation follows well-studied neurophysiological principles. Similar to the physiological condition, the nerve membrane is depolarized by the stimulus until the activation threshold is reached and action potentials are triggered for generation of muscle ...

Functional Electrical Stimulation

IEEE Control Systems, 2008
It is important to evaluate closed-loop FES (functional electrical stimulation) control systems using standard time- and frequency-domain performance metrics to facilitate the discussion of results between research groups. Moreover, uniform reporting of the performance of control methods expedites the process of developing clinically useful controllers

Functional electrical stimulation for stoke rehabilitation

Medical Hypotheses, 2012
tion. Also, regardless of the orthotic benefit of FES, the process of ‘‘learning-relearning’’ could vary from one individual to another depending upon the person’s inherent ability, and the type of neurological disorder and its severity. In general, this hypothesis therefore explains why individual might have short-lasting effect or no overall ...

Functional Electrical Stimulation Bicycle Ergometry

American Journal of Physical Medicine & Rehabilitation, 1989
Forty-seven patients who had participated in a clinical electrical stimulation ergometry program were administered a questionnaire to determine their perceptions of the therapy. Improved endurance was reported by 62% of paraplegics and 65% of quadriplegics. Sixty-two percent of paraplegics and 56% of quadriplegics reported improved self-image, while 54%

NEUROENDOCRINE CHANGES DURING FUNCTIONAL ELECTRICAL STIMULATION

American Journal of Physical Medicine & Rehabilitation, 1992
This study examined the effects of a computerized functional electrical stimulation exercise program on plasma beta-endorphin-like immunoreactivity (BEP-ir), cortisol levels and depression parameters in spinal cord-injured individuals. Nine subjects from 1.2 to 33.5 yr postinjury with both motor and sensory complete lesions between C5 and T12 ...
