  • Electrical Muscle Stimulation for Chronic Heart Failure: An Alternative Tool for Exercise Training?
    Current Heart Failure Reports, 2010
    Co-Authors: Prithwish Banerjee
    Abstract:

    Conventional exercise training has been shown conclusively to improve exercise capacity, quality of life, and even reduce mortality in chronic heart failure. Unfortunately, not all heart failure patients are suitable for conventional exercise programs for various reasons. The exciting new technique of Electrical Muscle Stimulation (EMS) of large groups of Muscles has been shown to produce a physiologic response consistent with cardiovascular exercise at mild to moderate intensities by increasing peak oxygen consumption, carbon dioxide production, ventilatory capacity, and heart rate. Additionally, there is improvement in Muscle strength. The handful of small studies that exist of home-based EMS training of leg Muscles in heart failure show that EMS produces similar benefits to conventional exercise in improving exercise capacity, making EMS an alternative to aerobic exercise training in those that cannot undertake conventional exercise. The improvement seen in leg Muscle strength promises also to improve mobility in this sedentary population.

  • prolonged Electrical Muscle Stimulation exercise improves strength peak vo2 and exercise capacity in patients with stable chronic heart failure
    Journal of Cardiac Failure, 2009
    Co-Authors: Prithwish Banerjee, Brian Caulfield, Louis Crowe, Andrew L Clark
    Abstract:

    Abstract Background Exercise training can help patients with chronic heart failure but may be limited in its applicability due to age and other comorbidities. This investigation evaluated training responses to prolonged Electrical Muscle Stimulation (EMS) in patients with stable chronic heart failure. Methods and Results In a crossover designed study, 10 patients (age 66 ± 6.5 years, 9 male) were randomized to 8 weeks of training or habitual activity before crossing over to the other limb after a washout period of 2 weeks. Training consisted of Electrical Muscle Stimulation of the major leg Muscles for a minimum of 1 hour, 5 days a week. Peak oxygen consumption, 6-minute walking distance test, body mass index, and quadriceps Muscle strength were the end points. At baseline the mean values for peak oxygen consumption (VO 2 ), 6-minute walking distance, quadriceps strength, and body mass index were 19.5 ± 3.5 mL·kg·min, 415.1 ± 56.6m, 377.9 ± 110.4N, and 27.9 ± 3.1kg/m 2 , respectively. After training, peak VO 2 increased to 21.2 ± 5.1 mL·kg·min ( P P P P > .05). Conclusions EMS can be used in sedentary adults with stable chronic heart failure to improve physical fitness and functional capacity. It may provide a viable alternative for patients unable to undertake more conventional forms of exercise.

  • cardiac cycle synchronized Electrical Muscle stimulator for lower limb training with the potential to reduce the heart s pumping workload
    PLOS ONE, 2017
    Co-Authors: Kenichiro Sasaki, Toshio Moritani, Hiroo Matsuse, Ryuji Akimoto, Shiro Kamiya, Motoki Sasaki, Yuta Ishizaki, Masanori Ohtsuka, Takaharu Nakayoshi, Takafumi Ueno
    Abstract:

    Background The lower limb Muscle may play an important role in decreasing the heart’s pumping workload. Aging and inactivity cause atrophy and weakness of the Muscle, leading to a loss of the heart-assisting role. An Electrical lower limb Muscle stimulator can prevent atrophy and weakness more effectively than conventional resistance training; however, it has been reported to increase the heart’s pumping workload in some situations. Therefore, more effective tools should be developed. Methods We newly developed a cardiac cycle-synchronized Electrical lower limb Muscle stimulator by combining a commercially available electrocardiogram monitor and belt electrode skeletal Muscle Electrical stimulator, making it possible to achieve strong and wide but not painful Muscle contractions. Then, we tested the stimulator in 11 healthy volunteers to determine whether the special equipment enabled lower limb Muscle training without harming the hemodynamics using plethysmography and a percutaneous cardiac output analyzer. Results In 9 of 11 subjects, the stimulator generated diastolic augmentation waves on the dicrotic notches and end-diastolic pressure reduction waves on the plethysmogram waveforms of the brachial artery, showing analogous waveforms in the intra-aortic balloon pumping heart-assisting therapy. The heart rate, stroke volume, and cardiac output significantly increased during the Stimulation. There was no change in the systolic or diastolic blood pressure during the Stimulation. Conclusion Cardiac cycle-synchronized Electrical Muscle Stimulation for the lower limbs may enable Muscle training without harmfully influencing the hemodynamics and with a potential to reduce the heart’s pumping workload, suggesting a promising tool for effectively treating both locomotor and cardiovascular disorders.

  • low intensity Electrical Muscle Stimulation induces significant increases in Muscle strength and cardiorespiratory fitness
    European Journal of Sport Science, 2016
    Co-Authors: Toshiaki Miyamoto, Akira Tamaki, Hiroyuki Kamada, Toshio Moritani
    Abstract:

    AbstractThe aim of this study was to investigate the effect of low-intensity exercise training using belt electrode skeletal Muscle Electrical Stimulation on Muscle strength and cardiorespiratory fitness in healthy subjects. Nineteen healthy subjects were allocated into control or intervention groups; in both groups the participants kept regular physical activity while the intervention group underwent 30 min B-SES training at 3–4 METs for four weeks. Knee extensor Muscle strength and cardiorespiratory endurance during incremental exercise test were measured at baseline and after four weeks for all participants. The relative change of knee extensor Muscle strength in the intervention group was significantly higher than control group (p < .05). Also, oxygen uptake at ventilator threshold and peak oxygen uptake during incremental exercise test significantly increased in the intervention group when compared with control group (p < .05). This study showed that prolonged low-intensity B-SES training resulted in...

  • Metabolic and cardiovascular responses during voluntary pedaling exercise with Electrical Muscle Stimulation
    European Journal of Applied Physiology, 2014
    Co-Authors: Kohei Watanabe, Yoshiki Taniguchi, Toshio Moritani
    Abstract:

    Purpose We aimed to test the effect of additional Electrical Muscle Stimulation (EMS) during moderate-intensity voluntary pedaling exercise on metabolic and cardiovascular responses. Methods Eleven healthy male subjects performed moderate-intensity pedaling exercise at a constant workload (80 % of ventilatory threshold) for 20 min while EMS was applied to thigh Muscles from 5 to 10 min and from 15 to 20 min during the exercise. Results A significantly higher oxygen uptake ( V O_2), heart rate, and respiratory gas exchange ratio were observed during the exercise periods with EMS despite the constant workload. These changes were accompanied by an elevated blood lactate concentration, suggesting the existence of additional fast-twitch motor unit (MU) recruitment during the exercise with EMS. Conclusion Our data suggest that the use of intermittent EMS during a constant load exercise mimics the high-intensity interval training, possibly due to additional fast-twitch MU recruitment and co-contractions of the quadriceps and hamstrings Muscles, leading to higher anaerobic metabolism and a lower mechanical efficiency.

  • effect of percutaneous Electrical Muscle Stimulation on postprandial hyperglycemia in type 2 diabetes
    Diabetes Research and Clinical Practice, 2012
    Co-Authors: Toshiaki Miyamoto, Kazuhito Fukuda, Tetsuya Kimura, Yasushi Matsubara, Kinsuke Tsuda, Toshio Moritani
    Abstract:

    Abstract Aims The aim of this study was to examine whether percutaneous Electrical Muscle Stimulation (EMS) attenuates postprandial hyperglycemia in type 2 diabetes. Methods Eleven patients with type 2 diabetes participated in two experimental sessions; one was a 30-min EMS 30 min after a breakfast (EMS trial) and the other was a complete rest after a breakfast (Control trial). In each trial, blood was sampled before and at 30, 60, 90, and 120 min after the meal. Results Postprandial glucose level was significantly attenuated in EMS trial at 60, 90, and 120 min after a meal (p  Conclusions The present results provide first evidence indicating that EMS is a new exercise method for treating postprandial hyperglycemia in individuals with type 2 diabetes, especially who cannot perform adequate voluntary exercise because of excessive obesity, orthopedic diseases, or severe diabetic complications.

  • effect of early implementation of Electrical Muscle Stimulation to prevent Muscle atrophy and weakness in patients after anterior cruciate ligament reconstruction
    Journal of Electromyography and Kinesiology, 2011
    Co-Authors: Satoshi Hasegawa, Masahiko Kobayashi, Ryuzo Arai, Akira Tamaki, Takashi Nakamura, Toshio Moritani
    Abstract:

    Objective: Following anterior cruciate ligament (ACL) reconstruction, restricted weight bearing and immobilization results in thigh and calf Muscle atrophy and weakness. The purpose of this study was to assess the effect of Electrical Muscle Stimulation (EMS) on prevention of Muscle atrophy in patients during the early rehabilitation stage after ACL reconstruction. Methods: Twenty patients with acute ACL tears were divided into two groups randomly. The control group (CON group) participated in only the usual rehabilitation program. In addition to this protocol, the Electrical Muscle Stimulation group (EMS group) received EMS training using the wave form of 20 Hz exponential pulse from the 2nd post-operative day to 4 weeks after the surgery. Results: Muscle thickness of vastus lateralis and calf increased significantly 4 weeks after surgery in the EMS group, while it decreased significantly in the CON group. The decline of knee extension strength was significantly less in the EMS group than in the CON group at 4 weeks after the surgery, and the EMS group showed greater recovery of knee extension strength at 3 months after surgery. Conclusions: EMS implemented during the early rehabilitation stage is effective in maintaining and increasing Muscle thickness and strength in the operated limb.
