“…This technology grants better stability of the conductive lines while maintaining low linear impedance and thinner isolated lines, thus allowing for denser routing on flexible dielectric substrates. Single channel NMES is known to be suboptimal and prone to fatigue [11] compared to physiological muscle recruitment. The use of EAs allows exploitation of spatial and temporal summation effects on the targeted anatomical structures.…”

Reaching and grasping impairments significantly affect the quality of life for people who have experienced a stroke or spinal cord injury. The long-term well-being of patients varies greatly according to the restorable residual capabilities. Electrical stimulation could be a promising solution to restore motor functions in these conditions, but its use is not clinically widespread. Here, we introduce the HandNMES, an electrode array (EA) for neuromuscular electrical stimulation (NMES) aimed at grasp training and assistance. The device was designed to deliver electrical stimulation to extrinsic and intrinsic hand muscles. Six independent EAs, positioned on the user forearm and hand, deliver NMES pulses originating from an external stimulator equipped with demultiplexers for interfacing with a large number of electrodes. The garment was designed to be adaptable to user needs and anthropometric characteristics; size, shape, and contact materials can be customized, and stimulation characteristics such as intensity of stimulation and virtual electrode location, and size can be adjusted. We performed extensive tests with nine healthy subjects showing the efficacy of the HandNMES in terms of stimulation performance and personalization. Because encouraging results were achieved, in the coming months, the HandNMES device will be tested in pilot clinical trials.

“…FES cycling has a low efficiency, 17 but the decrease in submaximal VO 2 in the hybrid cycling group might indicate that it can improve because of training. The reduction in HR rest for both training groups, suggesting an improved cardiorespiratory fitness, 18 and the increased subjectively experienced fitness observed, support previously reported findings regarding the positive effects of hybrid cycle and handcycle training on fitness.…”

“…Despite the higher _ VO 2peak observed in FES-rowing and FES-hybrid exercise, there is still insufficient or conflicting evidence whether the relative aerobic and metabolic demands of these activities are sufficient enough to bring about meaningful change in cardiorespiratory fitness. For example, the utility of FESaugmented exercise with respect to metabolic efficiency and demand has been questioned as the underlying mechanisms resulting in modest increases in _ VO 2peak may not sufficiently challenge the cardiorespiratory system to the extent needed for positive adaptation [103][104][105]. In the case of those with motor-complete SCI, this fact may be inconsequential as any opportunity to increase activity is likely better than none, and the added benefit of FESaugmented exercise as it relates to improved muscle structure and function can still be realized using this technology.…”

The primary aims of this report are to provide a review of current literature pertaining to fitness and healthrelated outcomes following spinal cord injury (SCI), to identify the common and relevant fitness assessment techniques, to describe key evidence-based intervention strategies for improving health-related components of fitness among persons with SCI and to identify emerging and future trends in health-related fitness programming for rehabilitation and research. SCI results in a partial or total loss of neural signal transmission at and below the level of injury, characterized by motor and sensory loss. About 250,000-400,000 individuals have a SCI in the USA with approximately 12,000 new injuries occurring annually. The loss of somatic and autonomic control results in a reduction of physical activity and blunted cardiovascular response to exercise. The consequences of this reduction in physical activity are significant physical deconditioning, altered body composition, and development of detrimental metabolic profiles leading to poorer health outcomes in this population. Over the past decade, much attention has been devoted to understanding the relationship between exercise participation, physical activity, and physical fitness and their impact on health-related outcomes following SCI. Physical fitness interventions are of great importance to the SCI consumer and clinicians whose goals are to halt the deconditioning process, increase functional capacity, and decrease secondary health complications associated with chronic SCI. Exercise risk evaluation and individualized fitness assessments for body composition, muscular strength/endurance, and cardiorespiratory fitness should precede implementation of exercise interventions. Current evidence indicates that both electrically stimulated and volitional exercise strategies have the potential to improve components of fitness, reduce the risk of secondary health complications, and positively impact overall health for those with chronic physical disability. However, given the complexity of SCI with respect to level and severity of injury, a clear consensus on the optimal frequency, duration, and intensity of exercise needed to ensure lasting effects on health-related outcomes has yet to be determined. In addition, as is the case in non-injured populations, consideration should be given to both diet and exercise, not exercise alone, when considering the optimal strategy for improving body composition and cardiovascular health for persons with SCI.
