- PublicationAn investigation into the acute effects of electrical muscle stimulation on cardiopulmonary function in a chronic obstructive pulmonary disease patient - a pilot case study(2010-04)
; ; ; ; ; Chronic obstructive pulmonary disease (COPD) patients commonly find it difficult to participate in conventional aerobic exercise training owing to limited cardiopulmonary reserve, excessive dyspnoea and muscle fatigue. Recent studies have shown that significant improvements in oxygen consumption can be gained post 6-week electrical muscle stimulation (EMS) training. Low frequency currents elicit a sustained and significant aerobic response and may be appropriate for COPD patients, who cannot exercise in a conventional manner. A recent study compared the acute metabolic response among COPD patients during resistance training and EMS, using a tetanic frequency of 75 Hertz (Hz), however no investigations have reported on the acute effects of EMS on cardiopulmonary function in a COPD population, using low frequency stimulation current.322 - PublicationThe effects of electrical muscle stimulation training in a chronic obstructive pulmonary disease population – a pilot study(2010-04)
; ; ; ; ; Exercise training is currently advocated as a therapeutic modality for improving the systemic manifestations of chronic obstructive pulmonary disease (COPD) -including peripheral muscle dysfunction, decreased exercise tolerance, weight loss, depletion of muscle mass and muscle strength and poor health status. Owing to a limited cardiopulmonary reserve, COPD patients are frequently physically unable to tolerate sufficient training intensities which would afford them with the benefits associated with conventional exercise training interventions. Electrical muscle stimulation (EMS) appears to have a limited demand on ventilatory requirements and dyspnoea, and may be a promising exercise training alternative for patients with COPD.345
