Test Analysis

The current study aimed to determine the effects of neuromuscular electrical stimulation (NMES) on equine rectus abdominis using surface electromyography (sEMG) and ultrasonographic muscle thickness evaluation. Five horses were trained with NMES for 12 weeks; muscle thickness and sEMG evaluations were obtained before and after the training period. Three different tests were carried out for sEMG evaluations: Test A tried to elicit a voluntary maximal isometric contraction (VMIC); Test B used NMES to elicit a muscular contraction; and Test C used 1 ms repetitive electrical impulses to elicit a series of M-waves. Muscle strength was evaluated from the root mean square (RMS; Tests A and B) and peak to peak (PP; Test C) values obtained from the sEMG data. Measures related to amplitude (RMSa; RMSm; RMSa; PP) were normalised with their pre-training values for every muscle prior to statistical analysis, leading to values as a proportion of the initial value. The evaluation of muscle fatigue was performed using a Fourier test analysis of the frequency range, obtaining the median frequency (MF) for all tests. Muscle thickness (MT) was measured by ultrasound of left and right sides of the rectus abdominis. Data were analysed using non parametric test of Wilcoxon (Test A RMSa; Test A RMSm; Test B RMSa; Test B RMSm; Test C PP; MT; P<0.05) and t-test (Test A MF; Test B MF; Test C MF; P<0.05). Statistical differences were observed between baseline and trained horses. Muscle force increase following NMES training in Test B (RMSa 2.50±0.69; RMSm 2.59±0.76) and Test C (PP 5.20±1.76). Fatigue of the rectus abdominis decreased in Test A (168.33±55.19 vs 232.63±44.15 Hz) and Test C MF (187.93±20.76 vs 236.98±52.39 Hz), but not in Test B (363.98±45.48 vs 327.95±50.84 Hz). The difference in muscle thickness between the two groups was not significant (10.96±0.64; 11.78±0.79 mm). The results suggest that NMES training could be used as an effective method to increase muscle force and fatigue resistance of the rectus abdominis muscle in the horse.

Abstract Objective To examine the effect of neuromuscular electrical stimulation (NMES) combined with core stabilization exercises (CSE) in patients with chronic low back pain (CLBP). Methods Thirty-six patients (mean age 33.6±12.6 years) with CLBP were randomly assigned to 4 weeks (12 sessions) of NMES group (NMES combined with CSE) (n=18) vs. Control group (sham NMES and CSE) (n=18). After the 4 weeks, same exercises were given as home exercise program without NMES. The outcome measures were Oswestry Disability Index (ODI), Visual Analog Scale (VAS), Nottingham Health Profile (NHP) and ultrasonography. Ultrasonography was used for measuring transversus abdominis (TrA), internal oblique (IO), external oblique (EO) muscles thickness and lumbar multifidus muscle thickness and area. Assessments were performed at baseline and 4th week and eighth week follow-up. Results In both groups, the change of ODI, VAS and NHP values of the first measurement according to the values of the 4th week and the eighth week were found statistically significant (p=0.001; p<0.01). There were no statistically significant differences in ODI, VAS and NHP scores between the 4th week and the eighth week in both groups (p>0.05). None of NMES and control group measurements with US showed a statistically significant increase in the TrA, IO, EO thickness and multifidus thickness and area (p>0.05). Conclusions It was shown that NMES can be tolerated by patients with CLBP, but the addition of simultaneus NMES to CSE had no contribution to the clinical outcome measures.

Context: Neuromuscular electrical stimulation (NMES) combined with blood flow restriction (BFR) has been shown to improve muscular strength and size better than NMES alone. However, previous studies used varied methodologies not recommended by previous NMES or BFR research. Objective: The present study investigated the acute effects of NMES combined with varying degrees of BFR using research-recommended procedures to enhance understanding and the clinical applicability of this combination. Design: Randomized crossover. Setting: Physiology laboratory. Participants: A total of 20 healthy adults (age 27 [4] y; height 177 [8] cm; body mass 77 [13] kg). Interventions: Six sessions separated by at least 7 days. The first 2 visits served as familiarization, with the experimental conditions performed in the final 4 sessions: NMES alone, NMES 40% BFR, NMES 60% BFR, and NMES 80% BFR. Main Outcome Measures: Maximal voluntary isometric contraction, muscle thickness, blood pressure, heart rate, rating of perceived exertion, and pain were all recorded before and after each condition. Results: The NMES 80% BFR caused greater maximal voluntary isometric contraction decline than any other condition (−38.9 [22.3] N·m, P < .01). Vastus medialis and vastus lateralis muscle thickness acutely increased after all experimental conditions (P < .05). Pain and ratings of perceived exertion were higher after NMES 80% BFR compared with all other experimental conditions (P < .05). No cardiovascular effects were observed between conditions. Conclusion: The NMES combined with 80% BFR caused greater acute force decrement than the other conditions. However, greater perceptual ratings of pain and ratings of perceived exertion were observed with NMES 80% BFR. These acute observations must be investigated during chronic interventions to corroborate any relationship to changes in muscle strength and size in clinical populations.

Abstract Background Critically ill traumatic brain injury (TBI) patients experience extensive muscle damage during their stay in the intensive care unit. Neuromuscular electrical stimulation (NMES) has been considered a promising treatment to reduce the functional and clinical impacts of this. However, the time needed for NMES to produce effects over the muscles is still unclear. This study primarily aimed to assess the time needed and effects of an NMES protocol on muscle architecture, neuromuscular electrophysiological disorder (NED), and muscle strength, and secondarily, to evaluate the effects on plasma systemic inflammation, catabolic responses, and clinical outcomes. Methods We performed a randomized clinical trial in critically ill TBI patients. The control group received only conventional physiotherapy, while the NMES group additionally underwent daily NMES for 14 days in the lower limb muscles. Participants were assessed at baseline and on days 3, 7, and 14 of their stay in the intensive care unit. The primary outcomes were assessed with muscle ultrasound, neuromuscular electrophysiology, and evoked peak force, and the secondary outcomes with plasma cytokines, matrix metalloproteinases, and clinical outcomes. Results Sixty participants were randomized, and twenty completed the trial from each group. After 14 days, the control group presented a significant reduction in muscle thickness of tibialis anterior and rectus femoris, mean of − 0.33 mm (− 14%) and − 0.49 mm (− 21%), p < 0.0001, respectively, while muscle thickness was preserved in the NMES group. The control group presented a higher incidence of NED: 47% vs. 0% in the NMES group, p < 0.0001, risk ratio of 16, and the NMES group demonstrated an increase in the evoked peak force (2.34 kg/f, p < 0.0001), in contrast to the control group (− 1.55 kg/f, p < 0.0001). The time needed for the NMES protocol to prevent muscle architecture disorders and treat weakness was at least 7 days, and 14 days to treat NED. The secondary outcomes exhibited less precise results, with confidence intervals that spanned worthwhile or trivial effects. Conclusions NMES applied daily for fourteen consecutive days reduced muscle atrophy, the incidence of NED, and muscle weakness in critically ill TBI patients. At least 7 days of NMES were required to elicit the first significant results. Trial registration The trial was registered at ensaiosclinicos.gov.br under protocol RBR-8kdrbz on 17 January 2016.

Aim: This study investigated the effect of neuromuscular electrical stimulation (NMES) on masseter muscle thickness and maximal bite force among healthy community-dwelling elderly persons older than 65 years. Materials and methods: A total of 40 participants were randomly assigned to the experimental and placebo groups. In the experimental group, NMES was applied to both masseter muscles, and electrical signals were gradually increased until the participants felt a grabbing sensation (range 6.0–7.5 mA) in the masseter muscle. The placebo group, in contrast, underwent NMES in the same manner and procedure as the experimental group with less electrical intensity (0.5 mA). All interventions were administered five times a week for six weeks, 20 min per day. The outcomes were masseter muscle thickness assessed using ultrasound and maximal bite force using a bite force meter. The level of significance was set as p < 0.05. Results: The experimental group showed a significant increase in both masseter muscle thickness and maximal bite force as compared with the placebo group (p = 0.002 and 0.019, respectively). Moreover, the degree of change in the masseter muscle thickness and maximal bite force significantly increased in the experimental and placebo groups (p < 0.001, both). Conclusions: This study demonstrated that NMES could be an effective modality for increasing masseter muscle thickness and maximal bite force in healthy older adults.
