- 205-Electrical Stimulation : Neurophysiological Basis and Application

  title={- 205-Electrical Stimulation : Neurophysiological Basis and Application},
  author={Jerrold Scott},
Electrical stimulation has been used for thousands of years for a variety of purposes including muscle reeducation, muscle strength training and wound healing. However, because it has been used most commonly by individuals in money making schemes, it has been sometimes considered the domain of quacks and charlatans. But electrical stimulation can be a potent tool in the clinical setting if properly used for muscle strength training, endurance training, reducing muscle spasticity, motor… 

Optimal FES parameters based on mechanomyographic efficiency index

An MMG efficiency index (EI) that may indicate most efficient FES electrical parameters to control functional movements is presented and FES profile set to 1kHz pulse frequency, 200εs active pulse duration and burst frequency of 50Hz was the most efficient.

Artificial motor control for electrically stimulated upper limbs of plegic or paretic people

It is concluded that FES with closed-loop feedback and feedforward are the most used and most viable systems for upper limbs motor control, because they perform self-corrections slowing neuromuscular adaptation, allowing different planes and more range of movement and sensory-motor integration.

Preliminary study of functional electrical stimulation: Application of swinging trajectory based on knee-joint range-of-motion (ROM)

Nowadays, research and developments of control system for spinal cord injury (SCI) using functional electrical stimulation (FES) is widely used. Restoring mobility to persons with paraplegia with

The Effects of Electrical Muscle Stimulation (EMS) towards Male Skeletal Muscle Mass

The application of EMS towards body composition can increase the muscle size and strength and this method has been proven to be able to improve athlete strength and thus, may be implemented in the sports science area of knowledge.

The addition of electrical stimulation to progressive resistance training does not enhance the wrist strength of people with tetraplegia: a randomized controlled trial

Voluntary strength of the wrist is not enhanced by the addition of electrical stimulation to progressive resistance training programs in people with tetraplegia.

Cycling induced by functional electrical stimulation improves the muscular strength and the motor control of individuals with post-acute stroke. Europa Medicophysica-SIMFER 2007 Award Winner.

Rehabilitation including FES cycling was more effective in promoting muscle strength and motor recovery of the lower extremity than therapist-assisted SR alone.

Optimization of a FES Cycling Neuroprosthesis on Stroke Patients by Means of the Left and Right Crank Measurements

Results demonstrated that the proposed sensors could be successfully used to monitor online the unbalance of the cycling and could offer a good signal for biofeedback neuroprostheses and for closed loop controllers.

Convex Hull Area in Triaxial Mechanomyography during Functional Electrical Stimulation

The convex hull area can be a candidate to follow muscle fatigue during FES-elicited contractions and analysis of short length epochs during closed-loop FES systems.

Relationship between peak and mean amplitudes of the stimulating output voltage for functional control of the knee by spinal cord patients and healthy volunteers

The FES profile (100 µs - 50 Hz) seems to be the most suitable for both groups, inasmuch as it presents smaller mean amplitudes and peak amplitudes similar to other FES profiles.

Effect of Electrical Stimulation to Prevent Muscle Atrophy on Morphologic and Histologic Properties of Hindlimb Suspended Rat Hindlimb Muscles

Results suggest that short periods of low-intensity, low-stimulation frequency ES of muscle during periods of inactivity could maintain changes in both morphologic and histologic properties of the slow-twitch muscle fibers (soleus).



Electrical parameters for over-the-skin muscle stimulation.

Effects of electrical stimulation on spinal spasticity.

Combining results from two separate but similar studies it is contended that about one-half of randomly selected SCI patients with knee joint spasticity might benefit by electrical stimulation.

The Physiology of Neuromuscular Electrical Stimulation

A brief discussion of the physiology and theory supporting the use of NMES, including explanation of various waveforms, factors influencing fatigue, and stimulus parameters are presented.

Force, Pain and Electrode Size in the Electrical Stimulation of Leg Muscles

The development of devices to make possible the locomotion of patients with totally paralysed lower limbs and the existing musculature might be used as the motor drive if suitably programmed stimuli were applied directly to the muscles or to the motor nerves.

Electrical stimulation to reduce chronic toe-flexor hypertonicity. A case report.

This patient benefitted dramatically from the use of electrical stimulation in inhibiting hypertonicity, and I believe this modality may be helpful in other cases dealing with increased muscle tone.

Optimal stimulus parameters for minimum pain in the chronic stimulation of innervated muscle.

Analysis of voltage and current wave forms for the different stimulus parameters indicated that the sensation of pain was dependent upon the total amount of electrical charge delivered to the tissue with the pulse.

Optimal stimulation of paralyzed muscle after human spinal cord injury.

The occasional spasms occurring in complete spinal cord-injured subjects are not sufficient to maintain normal muscle properties, but these properties can largely be restored by 1-2 h/day of electrical stimulation.
