Electrical nerve stimulation is an efficient way to manage pain brought on by many medical problems. A TENS unit operates on batteries and is contained in a little box that can fit into a pocket. The case encloses the battery and the controller. The device delivers an electrical signal to the nerves to counteract pain signals from the brain. The intensity, pulse width and frequency are adjustable with respect to the level of pain. Users are able to adjust the machine until they discover the setting that actually works best for them. The mixture of settings that actually works great for one patient may have no effect as well as be painful for an additional patient. Since every person is different, home TENS units gives each patient the ability to adjust their treatment to satisfy their specific needs.
The electrical signal is delivered through one or more electrodes attached to patches that stick to the skin. The patches are put directly over the affected area and can stay firmly attached through the treatment cycle. Wires run from the controller to the electrodes. Depending on the intensity of the pain and the size of the affected region, the patient may wear multiple electrodes for the proper degree of stimulation required to block the pain. When used properly, the TENS unit is protected to use and patients report success in achieving pain relief when using the device. Even though the TENS is suitable for use by many people, users should heed the warnings regarding use under certain situations.
The TENS unit will not be used by an expectant mother because of potential side effects on the fetus. So far, the dangers are not yet fully documented, so it’s best for pregnant women to avoid while using device. While using unit could also have negative consequences for users having a pacemaker. This is especially dangerous when the electrodes are located on sides of the pacemaker. The flow of electricity can hinder the heartbeat and cause serious medical problems. Proper placement of the electrodes is vital for anyone having a history of heart trouble. Users should never place electrodes on the throat area or the head.
Consumers can choose from different types of TENS machine sales but proper maintenance is necessary regardless of mode. The battery should be checked before each use. Users should cleanse the area of skin within the affected area where the electrodes are to be attached.
The system must be powered down with the knobs within the off position keep. The user also needs to detach the wires from the electrodes and the controller. The electrode pads are left in place if another treatment will commence inside a short period. If the patient is done with the unit for the day, he or she should peel the pads carefully from the skin and wash them with water and mild soap. he skin must be kept clean too to eliminate the risk of any irritation from the adhesive on the electrode pads.
