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.

Introduction Neuromuscular electrical stimulation (NMES) could provide an alternative or adjunct treatment modality to induce muscle hypertrophy in the hip osteoarthritis population. This preliminary study evaluates the feasibility and acceptability of NMES to evoke involuntary muscle contractions in adults with advanced hip osteoarthritis. Methods Thirteen adults with moderate-to-severe hip osteoarthritis and fifteen healthy, older adults were invited to a lab-based testing session. NMES was applied unilaterally to the knee extensors and hip abductors for one continuous, five-minute testing session. Data were collected on device acceptability, tolerability and muscle contractile force, and compared between groups. Results Electrical stimulation of the knee extensors elicited a visible muscular contraction in 11 participants (85%) with hip osteoarthritis and 15 controls (100%) at an intensity acceptable to the participant. Electrical stimulation of the hip abductors elicited a muscular contraction in eight participants (62%) with osteoarthritis, and ten controls (67%). Muscle contractile force, pain, discomfort and acceptability did not differ between groups, however NMES of the knee extensors was favoured across all measures of assessment when compared to the hip abductors. Conclusions Electrical stimulation of the knee extensors may be a feasible and acceptable treatment modality to address muscle atrophy in adults with advanced hip osteoarthritis.

Abdominal Strength

Background:  Neuromuscular electrical stimulation (NMES) has been used clinically for many years as a modality to improve muscular strength and endurance.  Recently, equipment manufacturers have developed over-the-counter NMES units to target specific muscle groups, particularly the abdominal region.  Objective:  To study the effects of self-administered neuromuscular electrical stimulation (NMES) on changes in abdominal muscle strength and endurance, core strength, abdominal girth, and subjective measures of body satisfaction and shape.  Methods:  Fifty-three adults were randomly assigned into high intensity (HI: n=27) or low intensity (LI:  n=26) groups.  The NMES device for the LI group had been altered so that subjects felt some tactile sensation, but the intensity was not sufficient to elicit a muscular contraction.  All subjects stimulated their abdominal muscles 5 days per week (30 minutes per session) for 6 weeks.  Subjects were tested at Baseline, 2, 4, and 6 weeks.  Results:  The HI group had a significantly greater increase in strength at 4 weeks (19%) and 6 weeks (29%) compared to the LI group and performed significantly more curl-ups than the LI group at 2 weeks (62%).  Both groups had a significant increase in core strength over the course of the study, with no difference between groups.  There was no change in abdominal girth between groups.  Both groups had significant improvements in body satisfaction from Baseline to 4 weeks and Baseline to 6 weeks, with no significant interaction.  Conclusions:  Results of the current study indicate that high intensity NMES can significantly increase abdominal strength and endurance compared to LI intensity (control) stimulation.  Results for subjective measures tended to favor the HI group, but were less conclusive, since the LI group also had some positive changes.

Interstitial lung diseases are a large group of lung conditions characterized by inflammation and fibrosis. Interstitial lung disease in connective tissue diseases and rheumatoid arthritis is a severe complication of these pathologies. Apart from the pharmacological treatment, exercise training could help reduce breathing difficulties and increase physical strength, lower the burden of disease, help improving self-esteem and fight against depression and anxiety. Exercise training can be done either alone, or enhanced by auxiliary methods like oxygen administration, neuromuscular electrical stimulation or improving the strength of respiratory muscles. Possible associated lung diseases should be always taken into account. Even if exercise training is generally considered safe for this category of patients, there are also risks like exercise-induced hypoxemia, arrhythmia or pulmonary hypertension. Exercise training in this setting should be performed by dedicated physiotherapists after specialist prescription and under surveillance in a safe environment.
