lorance2 Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, is the 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 people who are partially or totally immobilized; 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 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]
A number of reviews have looked at the devices.
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency[1] range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies;[2][3] these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. Different sources specify different upper and lower bounds for the frequency range.
Light therapy—or phototherapy, classically referred to as heliotherapy—is a method recognized by scientific medicine for the treatment of various diseases. It includes exposure to outdoor daylight or specific indoor artificial light sources.
The care guideline for unipolar depression recommends light therapy especially for depression that follows a seasonal pattern (seasonal affective disorder).[1][2] There is tentative evidence to support its use to treat depressive disorders that are not seasonally dependent.[3][4][5] As a treatment for disorders of the skin, the second kind of light therapy, called ultraviolet light therapy, is meant to treat neurodermatitis, psoriasis, acne vulgaris, eczema and neonatal jaundice.
Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy. Cryotherapy may be used to treat a variety of tissue lesions.[1] The most prominent use of the term refers to the surgical treatment, specifically known as cryosurgery or cryoablation. Cryosurgery is the application of extremely low temperatures to destroy abnormal or diseased tissue and is used most commonly to treat skin conditions.
Cryotherapy is used in an effort to relieve muscle pain, sprains and swelling after soft tissue damage or surgery. For decades, it has been commonly used to accelerate recovery in athletes after exercise. Cryotherapy decreases the temperature of tissue surface to minimize hypoxic cell death, edema accumulation, and muscle spasms, all of which ultimately alleviate discomfort and inflammation.[2] It can be a range of treatments from the application of ice packs or immersion in ice baths (generally known as cold therapy), to the use of cold chambers.
While cryotherapy is widely used, there is little evidence as to its efficacy that has been replicated by or shown in large controlled studies. Its long-term side effects have also not been studied.[3][4] However, there is a study that concludes that cryotherapy has a positive impact on the short-term recovery of athletes. Cryotherapy helped manage muscle soreness and facilitate recovery within the first 24 hours following a sport-related activity. Athletes who use cryotherapy within the first 24 hours to alleviate pain recovered at a faster rate than athletes who did not use cryotherapy after their sport-related activity
