A typical battery-operated TENS unit is able to modulate pulse width, frequency, and intensity. TENS users need to try the unit for several days with several electrode placements before you decide to buy your own unit. In Britain, prior to the formation of the National Health Service in 1948, most hospitals and asylums were wholly or partly charitable institutions, and until the late 19th century were largely the preserve of the “deserving” poor. There are currently over 150 published articles on the use of CES to treat an array of disorders, and symptoms with positive treatment outcomes.52,53 Many frequencies from 0.5 Hz to 100 Hz have been used in the studies, with different frequencies being used to target different symptoms. Integrated with electrotherapy, electroacupuncture (EA) is traditional acupuncture connected with electric stimulation apparatus, which is conducted by inserting acupuncture needles into the acupoints and then changing electric stimulation parameters, including the stimulation frequency, current intensity, pulse width, and pulse interval. It is suggested that short treatment times are initially adopted especially with an acute case. Another situation in which polarity has been suggested to make a difference involves the use of electrotherapy to retard the formation of edema.

Electrotherapy (also known as electrical muscle stimulation or e-stim) uses an electrical machine that delivers electrical impulses to a patient’s body. It effectively slows down or distracts the message from the nerve to the brain. Although numerous individuals have claimed to benefit from transcranial electrical stimulation, there has been a tendency to downplay these accounts or attribute them to the power of suggestion, because of the professional knowledge and status of doctors, the investment in pain and discomfort made by patients, and also the multisensory drama and power of electrotherapeutic processes. The currents are passed through the skin at the same time, where they are set up so that their paths cross to simply interfere with each other. For example, iontophoresis can be accomplished only with a continuous monophasic current and, even then, only when the drug is applied to the correct electrode. There should be a presumption of sincerity unless evidence suggests otherwise (manufacturers of electrical apparatus, for instance, had a clear incentive to extol and exaggerate the benefits of their machines). If you would like to know how the Physiotherapy team at Cilliers & Swart Physiotherapists can help you live with less pain and get back to feeling great again - we invite you to give us a call. Alleviation of acute and chronic edema (by accelerating absorption rate, affecting blood vessel permeability, and increasing mobility of protein, blood cells, and lymphatic flow). If using the Compex® Wireless device, place one end of the wireless pod and attach it to the electrode. Further work is needed to see whether these early promising studies replicate. Doctors and psychiatrists who promoted it strove to differentiate themselves from the numerous quacks, healers, and instrument makers active in the medical marketplace by various means, including claiming superior knowledge, education, qualifications, and expertise. Varying with the specific frequencies used for the stimulation, it reportedly produces a neurological response in the brain and other components of the nervous system that reduces pain, anxiety, hypervigilance, depression and more. The current comes from a battery source that looks like a transcutaneous electrical nerve stimulation (TENS) device, but has a high-frequency cycling design. CES has been shown to increase electrical brainwave patterns in the alpha range (8–12 Hz), creating a calming, euphoric and soothing effect. Having identified the modality that is best able to achieve the effects required, the next clinical stage is to make a ‘dose’ selection. The other situation in which polarity clearly matters involves the stimulation of denervated muscle for preventing disuse atrophy; however, this application is less important in the rehabilitation of athletic injuries. If precautions are followed, no tissue is ordinarily damaged. Transcutaneous electrical nerve stimulation (TENS) is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes. Its frequency is 27 120 000 Hz, and the wavelength is about 11 m. The types of applications are condenser field method and cable method (Figures 1 and 2). In acupuncture delivery of electrical currents through needles is termed electro-acupuncture (ASAP 2007). As we have seen, electrotherapy was employed for a variety of medical and psychiatric purposes across Europe and in North America between 1750 and 1950, through the activities of scientific lecturers, natural philosophers, electricians, medical practitioners, and the incentives of the medical marketplace. 3. A meta-analysis of low level (non-thermal) laser therapy concluded this has small short term effects on pain relief, range of movement and reduction in morning stiffness (Brosseau et al 2005).
