Electrical Stimulation Is Not a Shortcut for ExerciseWhat is the problem and what is known about it so far?Electrical muscle stimulation is sometimes used to help people with nerve damage or disease who cannot move their muscles well. This can help keep under-used muscles healthy. In this sense, stimulating muscles with electricity is similar to exercise. It has been proved that exercising helps control the effects of diabetes. Exercise also helps ward off cardiovascular disease (disease of the heart and blood vessels). Some have suggested that electrical stimulation may provide the same benefits as exercising. Why did the researchers do this particular study?They wanted to see whether electrical muscle stimulation was beneficial for people with diabetes. Who was studied?The study included five people with type 2 diabetes and 33 people without diabetes. How was the study done?Participants had a physical exam and blood tests. Each person used electrical muscle stimulation every day for 12 weeks. At the study's end, participants had another exam and more blood tests. What did the researchers find?Electrical stimulation increased peoples' heartbeats while in use. However, the changes were considered too small to affect health. What were the limitations of the study?The study had a small number of participants. A study with more people may have led to different results. What are the implications of the study?Electrical stimulation is not a substitute for physical activity. People should not be tricked by products that promise improved muscle tone and health without exercise. Doctors should continue to encourage patients to be physically active. |
