In our recent effort, we introduced a submaximal index that utilized ventilatory efficiency relative to CO2 production (VE/ CO2) to evaluate the cardiovascular effectiveness to functional electrical stimulation lower-extremity cycling (FESLEC) in persons with spinal cord injury (SCI) (Gorgey and Lawrence, 2016). When compared to the resting state, we found that an acute bout of FES-LEC resulted...

Individuals with C5/C6 spinal cord injury have paralyzed elbow extensors, yet retain weak to strong voluntary control of elbow flexion and shoulder function. Previous studies have shown that functional electrical stimulation (FES) of the triceps provides sufficient elbow extension strength and control to greatly improve function. With triceps stimulation applied at a constant level, elbow angle...

OBJECTIVE To compare neurological and functional outcomes between two groups of hospitalised patients with subacute tetraplegia. APPROACH Seven patients received 20 sessions of brain computer interface (BCI) controlled functional electrical stimulation (FES) while five patients received the same number of sessions of passive FES for both hands. The neurological assessment measures were event ...

Abstract The effects of long-term Functional Electrical Stimulation (FES) assisted walking on ankle dynamic stiffness were examined in spinal cord injured (SCI) subjects with incomplete motor function loss. A parallelcascade system identification method was used to identify intrinsic and reflex contributions to dynamic ankle stiffness at different positions with subjects instructed to remain re...

OBJECTIVE Demonstrate brain perfusion changes due to neuronal activation after functional electrical stimulation (FES). METHOD It was studied 14 patients with hemiplegia who were submitted to a program with FES during fourteen weeks. Brain perfusion SPECT was performed before and after FES therapy. These patients were further separated into 2 groups according to the hemiplegia cause: cranial ...

Functional electrical stimulation (FES) has been applied to restore or maintain 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 for flexible waveform genera...

Cycling induced by Functional Electrical Stimulation (FES) training currently requires a manual setting of different parameters, which is a time-consuming and scarcely repeatable procedure. We proposed an automatic procedure for setting session-specific parameters optimized for hemiparetic patients. This procedure consisted of the identification of the stimulation strategy as the angular ranges...

Recent experimental and clinical work gives strong evidence that functional electrical stimulation (FES) is a powerful tool for regeneration, functional restoration and maintenance of denervated musculature, a fact that for various reasons was not recognized in the past. On reason was the lack of associated technology that in comparison to existing FES equipment for nerve stimulation has to mee...

Neurological disorders often manifest themselves in the form of movement deficit on the part of the patient. Conventional rehabilitation often used to address these deficits, though powerful are often monotonous in nature. Adequate audio-visual stimulation can prove to be motivational. In the research presented here we indicate the applicability of audio-visual stimulation to rehabilitation exe...
