Transcutaneous Electrical Nerve Stimulation, or TENS, is utilized for such discomfort conditions as post-surgical, visceral, neurological, sympathetically mediated, arthritic, myofacial and low back. It is also utilised to treat bladder incontinence. It is a single of the most commonly employed types of electro analgesia. Neuromodulation is produced by restoration of afferent input, direct inhibition of abnormally excited nerves, endogenous pain control and presynaptic inhibition in the dorsal horn of the spinal cord.
The unit consists of a single or a lot more electrical signal generators, electrodes and a battery. It is programmable and small and can provide stimuli with changeable existing, pulse widths and pulse rates. Biphasic is the favored waveform. Patients are advised to experiment with intensities and frequencies to uncover the best setting to give discomfort handle. Electrodes are placed over the area of pain and other points such as acupuncture websites, trigger points and cutaneous nerves.
There are three standard setting choices utilized that incorporate traditional, acupuncture-like and pulsed. With the conventional setting it utilizes a high frequency and low setting of intensity. The duration of the pulse is quick. Pain relief is efficient even though the device is on but discomfort returns when it is off. Individuals will leave the electrodes on all day and turn them on in 30 minute intervals. In some individuals the effects can last beyond the stimulus intervals. The acupuncture-like setting delivers a low frequency higher intensity stimulus . It can be uncomfortable and some patients cannot tolerate it, it is used when the standard approach does not function. Pulsed utilizes low intensity firing in high frequency bursts.
The comfort of the patient is really essential in figuring out the efficacy of the remedy. The higher pulse widths are more painful and the greater intensity impulse is as nicely. Electroconductive gel is applied on skin under the electrodes to reduce any blockage of the existing. Complications are rare but occasionally men and women will have skin irritation. The tape employed on the electrodes can cause irritation. Folks with pacemakers can have problems as nicely.
Initial relief of pain is skilled in 70 to 80 % of individuals but it decreases soon after a few months to about 20 to 30 %. Many individuals use the device on a daily basis. Pulse frequencies and patterns are adjusted consistently. The variety of outcomes fluctuates a excellent deal, most are favorable.
Following surgery TENS is very powerful in treating mild to moderate pain but is not effective in treating serious pain. There have been helpful outcomes in making use of it for myofacial and lower back discomfort. It has been helpful in treating diabetic neuropathy, urge incontinence and angina pecoria. For regaining motor function in stroke sufferers and to help with nausea in patients in chemotherapy it has been profitable.
TENS ought to not be utilized on patients who have pacemakers. It may cause premature labor in pregnant females. It ought to not be applied more than the carotid sinuses or the anterior neck. Electrodes need to not be placed more than places that have been burned. TENS should be employed very carefully with individuals that have an intrathecal pump or a spinal cord stimulator.
Transcutaneous Electrical Nerve Stimulation might assist to relieve some sorts of pain. It is great for quick-term relief as it is not as successful on chronic discomfort. It stimulates the production of endorphins.
