Abstract:
OBJECTIVE: To evaluate the effect of neuromuscular electrical stimulation (NMES) on cardiopulmonary function in healthy adults. METHOD: Thirty-six healthy adults without a cardiac problem were enrolled. All patients were randomly assigned to either a control (17 subjects, mean age 29.41) or an electrical stimulation group (19 subjects, mean age 29.26). The electrical stimulation group received NMES on both sides of quadriceps muscle using a Walking Man II(R) in a sitting position for 30 minutes over 2 weeks. Maximum oxygen consumption (VO2max), metabolic equivalent (MET), resting, maximal heart rate (RHR, MHR), resting, maximal blood pressure (RBP, MBP), and maximal rate pressure product (MRPP), exercise tolerance test (ETT) duration were determined using an exercise tolerance test and a 6 minute walk test (6MWT) before and after treatment. RESULTS: The electrical stimulation group showed a significant increase in VO2max (p=0.03), 6MWT (p<0.01), MHR (p<0.04), MsBP (p<0.03), ETT duration (p<0.01) and a significant decrease in RsBP (p<0.02) as compared with the control group after two weeks. NMES induced changes improved only in RsBP (p<0.049) and ETT duration (p<0.01). The effects of NMES training were stronger in females. CONCLUSION: We suggest that NMES is an additional therapeutic option for cardiopulmonary exercise in disabled patients with severe refractory heart failure or acute AMI.
