Imbalanced Biphasic Electrical Stimulation: Muscle Tissue Damage

[1990] Proceedings of the Twelfth Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1990
The effects of imbalanced biphasic stimulation were studied on cat skeletal muscle to determine if greater charge densities can be safely used than with balanced or monophasic stimulation. The results of the study indicate that imbalanced biphasic stimulation can be tolerated safely by tissue at or below a net dc current density of 35 microA/mm2 and ...

Cardiac assistance with electrically stimulated skeletal muscle

Medical and Biological Engineering and Computing, 1989
This study examined the ability of a skeletal muscle-powered assist ventricle (SMV) to augment cardiac output in ten dogs with pharmacologically induced heart failure under acute conditions. An SMV was surgically constructed in each dog by wrapping the untrained rectus abdominis muscle around a compressible pouch that was inserted into a left ...

Goldfish muscle energy metabolism during electrical stimulation

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1983
Concentrations of key metabolites were determined in goldfish red muscle, while muscle and blood before and after direct electrical stimulation of the myotome (60 pulses/min, amplitude 500 mV, 10 msec pulse duration, during 10 min at 20 degrees C). In white muscle, levels of ATP, aspartate and adenylate energy charge are significantly lowered while ...

Electric stimulation of the upper airway muscle

Current Opinion in Pulmonary Medicine, 1998
In various studies, it has been postulated that pharyngeal collapse occurring during sleep in obstructive sleep apnea may be alleviated by stimulating the genioglossus muscle. Basic experiments have demonstrated that neuromuscular stimulation applied intraorally via electrodes or by direct neural stimulation of the hypoglossal nerve might improve upper

Electrical Stimulation of Muscle: Field Stimulation

1975
Electrical field stimulation, in which the stimulating current is applied uniformly to the tissue, is useful in several experimental situations. All muscle cells are simultaneously, directly, and nearly equally stimulated. Since each cell is excited without the necessity of propagation, field stimulation ensures that all cells become activated in ...

Interleaved neuromuscular electrical stimulation reduces muscle fatigue

Muscle & Nerve, 2016
ABSTRACTIntroduction: Neuromuscular electrical stimulation (NMES) can be delivered over a muscle belly (mNMES) or nerve trunk (nNMES). Both methods generate contractions that fatigue rapidly due, in part, to non‐physiologically high motor unit (MU) discharge frequencies.

Control of Paralysed Axial Muscles by Electrical Stimulation

Acta Oto-Laryngologica, 1977
The function of a paralysed axial (laryngeal, facial, extraocular) muscle could conceivably be restored if it were made to contract again like its contralateral partner. A muscle stimulation device was designed and constructed so that the stimulus delivered to a given paralysed muscle was modulated by a signal reflecting the contractile state of its ...

EFFECTS OF ELECTRICAL MUSCLE STIMULATION ON OXYGEN CONSUMPTION

Journal of Strength and Conditioning Research, 2005
Electrical muscle stimulation (EMS) devices are being marketed as weight/ fat loss devices throughout the world. Commercially available stimulators have the ability to evoke muscle contractions that may affect caloric expenditure while the device is being used.

Electrical muscle stimulation for deep stabilizing muscles in abdominal wall

2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008
Low back pain is associated with dysfunction in recruitment of muscles in the lumbopelvic region. Effective rehabilitation requires preferential activation of deep stabilizing muscle groups. This study was carried out in order to quantify the response of deep stabilizing muscles (transverses abdominis) and superficial muscle in the abdominal wall ...

Static hysteresis loop of electrically stimulated muscles

Medical & Biological Engineering, 1974
The paper discusses the existence of a static hysteresis loop of a functionally electrically stimulated (f.e.s.) muscle. Hysteresis was observed in the relation between the amplitude of the stimulation pulses by which the muscles peroneus and tibialis anterior were stimulated, and the resulting dorsal flexion moment in the ankle joint.
