Electrical muscle stimulation – wikipedia gasbuddy nj

#########

Electrical muscle stimulation ( EMS), also known as neuromuscular electrical stimulation ( NMES) or electromyostimulation, is the gas natural inc elicitation of muscle contraction using electric impulses. EMS has received an increasing amount of attention in the last few years for many reasons: it can be utilized as a strength training tool for healthy subjects and athletes; it could be used as a rehabilitation and preventive tool for partially or totally immobilized patients; it could be utilized as a testing tool for evaluating the neural and/or muscular function in vivo; it could be used as a post-exercise recovery tool for athletes. [1] The impulses are generated by a device and are delivered through electrodes on the skin near to the muscles being stimulated. The electrodes are generally pads that adhere to the skin. The impulses mimic the action potential that comes from the central nervous system, causing electricity voltage used in usa the muscles to contract. The use of EMS has been cited by sports scientists [2] as a complementary technique for sports training, and published research is available on the results obtained. [3] In the United States, EMS devices are regulated by the U.S. Food and Drug Administration (FDA). [4]

In medicine, EMS is used for rehabilitation purposes, for instance in physical therapy in the prevention muscle atrophy due to inactivity or neuromuscular imbalance, which can occur for example after musculoskeletal injuries (damage to bones, joints, muscles, ligaments and tendons). This is distinct from transcutaneous electrical gas 87 89 91 nerve stimulation (TENS), in which an electric current is used for pain therapy.

The FDA rejects certification of devices that claim weight reduction. [13] EMS devices cause a calorie burning that is marginal at best: calories are burnt in significant amount only when most of the body is involved in physical exercise: several muscles, the heart and the respiratory system are all engaged at once. [14] However, some authors imply that EMS can lead to exercise, since people toning their muscles with gas x while pregnant electrical stimulation are more likely afterwards

Strength training by NMES does promote neural and muscular adaptations that are complementary to the well-known effects of voluntary resistance training. [1] This statement is part of the editorial summary of a 2010 world congress of researchers on the subject. Additional studies on practical applications, which came after that congress, pointed out important factors that make the difference between effective and ineffective EMS. [15] [16] This in retrospect explains why in the past some researchers and practitioners obtained results that others could not reproduce. Also, as published by reputable universities, EMS causes adaptation, i.e. training, of muscle fibers. [17] Because of the characteristics of skeletal muscle fibers, different types of fibers can be activated to differing degrees by different types of EMS, and the modifications induced depend on the pattern of EMS activity 9gag. [18] These patterns, referred to as protocols or programs, will cause a different response from contraction of different fiber types. Some programs will improve fatigue resistance, i.e. endurance, others will increase force production. [19] History [ edit ]

Luigi Galvani (1761) provided the first scientific evidence that current can activate muscle. During the 19th and 20th centuries, researchers studied and documented the exact electrical properties that generate muscle movement electricity usage by country. [20] [21] It was discovered that the body functions induced by electrical stimulation caused long-term changes in the muscles. [22] [23] In the 1960s, Soviet sport scientists applied EMS in the training of elite athletes, claiming 40% force gains. [24] In the 1970s, these studies were shared during conferences with the Western sport establishments. However, results were conflicting, perhaps because the mechanisms in which EMS acted were poorly understood. [25] Recent medical physiology research [26] [18] pinpointed the mechanisms by which electrical stimulation causes adaptation of cells of muscles, blood vessels [27] [28] [29] and nerves.

The U.S. Food and Drug Administration (FDA) certifies and releases EMS devices into two broad electricity inside human body categories: over-the counter devices (OTC), and prescription devices. OTC devices are marketable only for muscle toning; prescription devices can be purchased only with a medical prescription for therapy. Prescription devices should be used under supervision of an authorized practitioner, for the following uses:

The FDA mandates that manuals prominently display contraindication, warnings, precautions and adverse reactions, including: no use for wearer of pacemaker gas 1981; no use on vital parts, such as carotid sinus nerves, across the chest, or across the brain; caution in the use during pregnancy, menstruation, and other particular conditions that may be affected by muscle contractions; potential adverse effects include skin irritations and burns

From the 1950s, the company marketed the device for use in weight loss and fitness. Electrodes from the device were attached to the skin and caused muscle contractions by way of electrical currents. [33] The device caused 40 muscular contractions per minute in the muscles affected by the motor nerve gas 10 ethanol points in the area of each pad. The directions for use recommended use of the device at least 30 minutes daily for each figure placement area, and suggested that the user might use it for longer periods if they wished. The device was offered in a number of different models which were powered either by battery or household current. [39]

Relax-A-Cizors had from 1 to 6 channels. Two pads (or electrodes) were connected by wires to each channel. The user applied from 2 to 12 pads to various parts of their body. For each channel there was a dial which purported to control the intensity of the electrical current flowing into the user’s body between the two pads connected to that channel. [39]

The device was banned by the United States Food and Drug Administration in 1970 as it was deemed to be potentially unhealthy and dangerous to the users. [33] [39] The case gas bubble disease went to court, and the United States District Court for the Central District of California held that the Relax-A-Cizor was a device within the meaning of 21 U.S.C. § 321 (h) because it was intended to affect the gas bloating after eating structure and functions of the body as a girth reducer and exerciser, and upheld the FDA’s assertions that the device was potentially hazardous to health.
