Transcutaneous Electrical Nerve Stimulation, or TENS, is used for such pain conditions as post-surgical, visceral, neurological, affectionately mediated, arthritic, myofacial and low back. It is also used to treat bladder incontinence. It is one of the most typically used kinds of electro analgesia. Neuromodulation is produced by remediation of afferent input, direct restraint of unusually thrilled nerves, endogenous discomfort control and presynaptic inhibition in the dorsal horn of the spine cable.
The system includes one or more electrical signal generators, electrodes and a battery. It is programmable and small and can deliver stimuli with changeable current, pulse widths and even pulse rates. Biphasic is the favorite waveform. Patients are encouraged to explore strengths and frequencies to discover the very best setting to supply pain control. Electrodes are placed over the area of pain and other points such as acupuncture spots, trigger spots and cutaneous nerves.
There are three standard setting choices used that include traditional, acupuncture-like and pulsed. With the traditional setting it uses a high frequency and low setting of intensity. The period of the pulse is brief. Pain relief is effective while the device is on but discomfort returns whenever it is off. Clients will leave the electrodes on all the time and switch them on in 30 minute intervals. In some patients the effects can last beyond the stimulus periods. The acupuncture-like setting provides a radio frequency high strength stimulus. It can be uncomfortable and some patients can not endure it, it is used when the standard method does not work. Pulsed usages low strength firing in high frequency bursts.
The comfort of the client is essential in determining the efficacy of the treatment. The greater pulse widths are more uncomfortable and the higher intensity impulse is also. Electroconductive gel is used on skin under the electrodes to lessen any obstruction of the existing. Issues are uncommon however in some cases people will have skin inflammation. The tape utilized on the electrodes can cause inflammation. Individuals with pacemakers can get problems as well.
Initial relief of discomfort is experienced in 70 to 80 percent of patients but it decreases after a few months to around 20 to 30 percent. Numerous clients use the device on a daily basis. Pulse frequencies and patterns are changed consistently. The series of results fluctuates a fantastic deal, many are favorable.
After surgery TENS is very reliable in dealing with moderate to moderate pain but is ineffective in dealing with serious discomfort. There have actually been helpful results in utilizing it for myofacial and lower back pain. It has actually been helpful in treating diabetic neuropathy, desire incontinence and angina pecoria. For restoring motor function in stroke patients and to assist with nausea in clients in chemotherapy it has been effective.
TENS ought to not be used on patients who have pacemakers. It may trigger early labor in pregnant females. It ought to not be applied over the carotid sinuses or the anterior neck. Electrodes must not be put over locations that have actually been burned. 10S should be used carefully with patients that have an intrathecal pump or a spinal cable stimulator.
