“…38 In contrast with these results, a recent systematic review based on data from 14 trials investigated the evidence surrounding the use of abdominal electrical stimulation on respiratory function after spinal cord injury. 48 Although functional electrical stimulation was effective in improving respiratory function, the authors emphasized that further randomized, controlled trials, with larger samples and standardized protocols, were needed to fully establish the clinical efficacy of this interventions. Thus, the present results, which are based on only 2 trials of moderate methodological quality, cannot affirm the effects of electrical stimulation on respiratory function after stroke.…”

This systematic review reports 5 possible interventions used to improve respiratory function after stroke. Respiratory muscle training proved to be effective for improving inspiratory and expiratory strength, lung function, and dyspnea, and benefits were carried over to activity. However, there is still no evidence to accept or refute the efficacy of aerobic, breathing, and postural exercises, or the addition of electrical stimulation in respiratory function.

“…The Cochrane Library, MEDLINE, CINAHL, PEDro, Embase and PsycINFO databases were searched for relevant articles published up to June 2018. Manual searches of the reference lists of the selected studies and two previous systematic reviews were also conducted [10,11]. No restrictions were imposed in regard to language or year of publication.…”

“…Furthermore, ES appears to be well tolerated and has been studied in regard to its effects on preventing skeletal muscle atrophy as well as improving skeletal muscle volume and function. Although the effects of ES on muscle volume in patients with SCI remains unclear [7][8][9], a recent meta-analysis has suggested that ES of the abdominal muscles is an effective technique for improving respiratory function in such patients [10]. The only other meta-analysis found describes the possible effects of ES on increasing bone mineral density below the level of the injury in patients with chronic SCI [11].…”

Study design This work is a systematic review with meta-analysis Objective Evaluate the effect of electrical stimulation (ES) on skeletal muscle volume and spasticity in individuals with spinal cord injury (SCI). Setting University of Brasilia, Brazil Methods Searches were conducted of the Cochrane Library, MEDLINE, CINAHL, PEDro, PsycINFO and EMBASE electronic databases for relevant articles published up to June 2018. No restrictions were imposed regarding the year of publication. The inclusion criteria were randomized controlled trials involving adults with SCI comparing ES to an active or passive control. Two independent reviewers extracted the data from the selected studies and methodological quality was assessed using the PEDro scale. Results The initial search led to the retrieval of 164 studies, seven of which met the eligibility criteria, but only six were included in the meta-analysis. The six studies comprised 104 patients with complete or incomplete SCI. In the two studies that investigated the use of ES on muscle volume of the lower limbs, the overall effect was statistically significant in patients with acute SCI (mean difference: 0.86; 95% CI: 0.04 to 1.69; p < 0.04). Among the four studies that examined the use of ES for spasticity of the lower limb, the overall effect was non-significant (mean difference: 0.55; 95% CI: −0.31 to 1.41; p = 0.21). Conclusions Electrical stimulation was found to be an effective method for increasing muscle volume in SCI patients, but had no effect on spasticity. Further investigation of the effect of ES on spasticity in SCI is needed.

“…Previous studies have shown that abdominal ES might have an acute effect on cough peak flow and maximum expiratory pressure. [41][42][43] One could imagine that the effect of continuous abdominal ES on respiratory function might also influence wheelchair performance. Future studies should pay attention to this aspect.…”

Objective: In wheelchair rugby (WR) athletes with tetraplegia, wheelchair performance may be impaired due to (partial) loss of innervation of upper extremity and trunk muscles, and low blood pressure (BP). The objective was to assess the effects of electrical stimulation (ES)-induced co-contraction of trunk muscles on trunk stability, arm force/power, BP, and WR performance. Design: Cross-sectional study. Setting: Rehabilitation research laboratory and WR court. Participants: Eleven WR athletes with tetraplegia. Interventions: ES was applied to the rectus abdominis, obliquus externus abdominis and erector spinae muscles. For every test, the ES condition was compared to the non-ES condition. Outcome measures: Stability was assessed with reaching tasks, arm force/power with an isokinetic test on a dynamometer, BP during an ES protocol and WR skill performance with the USA Wheelchair Rugby Skill Assessment. Results: Overall reaching distance (ES 14.6 ± 7.5 cm, non-ES 13.4 ± 8.2 cm), and BP showed a significant increase with ES. Arm force (ES 154 ± 106 N, non-ES 148 ± 102 N) and power (ES 37 ± 26 W, non-ES 36 ± 25 W), and WR skills were not significantly improved. Conclusion: ES-induced trunk muscle activation positively affects trunk stability and BP, but not arm force/power. No effects were found in WR skill performance, probably due to abdominal strapping. More research is needed to assess different ES (training) protocols and longitudinal effects.
