“…Other previous studies on EMS, including AHF patients, have mainly used between-subjects comparisons such as randomized controlled trials (RCTs). [17][18][19][20][21][22]36,38) These studies may not be easily adaptable to the actual clinical field because they were targeted at a limited population based on many exclusion criteria and were conducted under specific environmental conditions. In contrast to their findings, our data may be highly versatile in the clinical setting.…”

“…EMS was performed on the right leg using belt electrode skeletal muscle electrical stimulation (B-SES) (General Therapeutic Electrical Stimulator; Homer Ion, Tokyo, Japan). 16,21,22,29) B-SES was applied to all the muscle groups of the right leg, including the quadriceps femoris, hamstrings, tibialis anterior, and triceps surae. The left leg was subjected to the usual rehabilitation.…”

“…The stimulator current waveform had a frequency of 20 Hz, with a pulse width of 250 μseconds, and the duty cycle involved stimulation for 5 seconds, with a pause for 2 seconds to produce cocontractions in the muscle groups of the lower limb. 21,22,29) To induce visible muscle contractions, the output intensity was set to the maximum tolerable value without discomfort or pain. EMS was performed for 20 minutes per day, 5 days per week, for 2 weeks.…”

“…Additionally, Arenja, et al 20) observed that EMS improved the 6-minutes walking distance in older adult patients with AHF. Notably, Tanaka, et al 21,22) reported that after the addition of EMS therapy to early rehabilitation in older AHF patients with frailty, an improvement in quadricep isometric strength and shortening of physical performance battery was observed. Nevertheless, the studies that have investigated the effects of EMS in AHF patients, without exception, have not revealed any changes in muscle volume, which is, consequently, a research limitation.…”

Electrical muscle stimulation (EMS) is expected to be considered as an add-on therapy for the usual rehabilitation of patients with chronic heart failure (HF). However, it remains unclear whether EMS can reduce muscle volume loss in patients with acute HF (AHF) immediately after hospitalization. Therefore, the aim of this study was to investigate if EMS could reduce the lower-limb muscle volume loss in patients with AHF. In this single-center, retrospective, observational study, lower-limb skeletal muscle volume, quadriceps muscle layer thickness, and clinical events (worsening HF or kidney function) were evaluated in 45 patients with AHF (mean age, 77.4 ± 11.6 years, 31 males). All patients underwent EMS on the right leg, in addition to usual rehabilitation, for 20 minutes per day, 5 days per week, for 2 weeks. A two-factor (time × leg) analysis of variance was performed to compare the difference between the right leg (usual rehabilitation and EMS) and left leg (usual rehabilitation only). The skeletal muscle mass decreased by 11.6% ± 19.7% from baseline in the right leg and by 20.4% ± 16.1% in the left leg (interaction; F = 4.54, P = 0.036). The quadriceps muscle layer thickness decreased by 10.2% ± 7.1% from baseline in the right leg and by 13.5% ± 6.0% in the left leg (interaction; F = 10.50, P = 0.002). No clinical events were related to EMS. Results showed that EMS combined with usual rehabilitation for patients with AHF has the potential to inhibit muscle volume loss.

“…[ 9 ] In such situations, EMS presents an opportunity to increase adherence to an exercise program [ 10 ] and improve body composition and physical strength for patients. [ 4 ] Investigators have reported that EMS improves quadriceps strength and lower extremity function in frail older patients with acute heart failure, [ 11 ] preserves muscle mass and function in patients with sarcopenia, [ 12 ] improves balance and reduces fall risk among the elderly, [ 13 ] reduces deltoid atrophy after arthroscopic rotator cuff repair, [ 14 ] and improves quadriceps strength and decreases pain in patients with knee osteoarthritis. [ 15 ] However, there are few studies on the effectiveness of EMS, especially in patients in intensive care settings, which requires further research.…”

Background: Electrical muscle stimulation (EMS) activates muscles through electrical currents, resulting in involuntary muscle contractions. This study aimed to evaluate the immediate clinical effects of superimposing EMS on strength training compared with conventional exercise in healthy non-athletic adults. Methods: This study was a randomised, controlled, parallel-group trial conducted at a single centre. Forty-one healthy young volunteers were recruited and randomised into two groups: strengthening with superimposed EMS (S+E) and strengthening (S) groups. All participants underwent the 30 minutes of strength training program, three times a week for 8 weeks, consisting of core muscle exercises. Additionally, the S+E group received EMS during training, which stimulated the bilateral abdominal, gluteus, and hip adductor muscles. As the primary outcome measure, we evaluated the changes in muscle thickness, including the abdominal, gluteal, and hip adductor muscles, using ultrasound. Muscle thickness was measured in both resting and contracted states. For secondary outcomes, physical performance (Functional Movement System score, McGill’s core stability test, and hip muscle power) and body composition analysis were evaluated. All assessments were performed at the beginning and end of the intervention. Results: 39 participants (S+E group = 20, S group = 19) completed the study. The clinical characteristics and baseline functional status of each group did not differ significantly between the groups. After completion of the training, the S+E group showed more efficient contraction in most of the evaluated muscles. The resting muscle thickness did not differ significantly between the groups; however, the contracted muscle thickness in the S+E group was higher than that in the S group (p < 0.05). Physical performance and body composition were not significantly different between the two groups. No intervention-related complications were reported during the study. Conclusion: EMS seems to be a safe and reasonable modality for improving physical fitness in healthy individuals.

AimsThis study aimed to determine whether there is a difference in the prognostic value of sarcopenia diagnosed using dual‐energy X‐ray absorptiometry (DEXA) and that predicted by prediction equations in older patients with heart failure (HF).Methods and resultsWe included 269 patients (aged ≥65 years) who were hospitalized for HF. We used two appendicular skeletal muscle mass (ASM) prediction equations: (i) Anthropometric‐ASM, including age, sex, height, and weight, and (ii) Predicted‐ASM, including sex, weight, calf circumference, and mid‐arm circumference. ASM index (ASMI) was calculated by dividing the sum of the ASM in the extremities by the height squared (kg/m2). The cut‐off values proposed by the Asian Working Group for Sarcopenia 2019 were used to define low ASMI. The prognostic endpoint was all‐cause mortality. The median age of the cohort was 83 years [interquartile range (IQR): 75–87], and 135 patients (50.2%) were men. Sarcopenia diagnosed according to DEXA, Anthropometric measurements, and Predicted‐ASM was observed in 134 (49.8%), 171 (63.6%), and 157 (58.4%) patients, respectively. During the median follow‐up period of 690 days (IQR: 459–730), 54 patients (19.9%) died. DEXA‐sarcopenia [hazard ratio (HR), 2.33; 95% confidence interval (CI), 1.26–4.31; P = 0.007] was associated with all‐cause mortality after adjusting for pre‐existing risk factors, whereas Predicted‐sarcopenia (HR, 1.68; 95% CI, 0.87–3.25; P = 0.123) and Anthropometric‐sarcopenia (HR, 1.64; 95% CI, 0.86–3.12; P = 0.132) were not.ConclusionsSarcopenia diagnosed using DEXA was associated with poor prognosis in older patients with HF; however, the prediction equations were not.
