Why To Use The Tens unit
The word “TENS” is the acronym stands for Transcutaneous Electrical Nerve Stimulation. It is use to produce electronic current via device to simulate the nerves. It is a pocket size portable battery, which sends electronic impulses to certain part of the body for blocking pain and giving relief. The Tens Unit has two electrodes, which are connected to the body where pain exists. This battery is used to modulate pulse frequency, width and intensity. The high frequency of Tens Unit is about 50 Hz, with intensity below motor contraction and with low frequency of 10 Hz. This device is easily available at health care store Toronto.
Looking at the history of this device, we came to know that this device was used in ancient Greece, 63 AD. According to them pain was relief on standing on electrical fish at a seashore. In the era of 16th and 17th century, people used electronic devices for headache and other pains. The first patient wearable Tens Unit is of America. After the successful, experiment the device become popular all around the world. Today many people use Tens for pain relief and relaxation. It has good ranking among Health Care Products Canada.
The electronic currents produce by this device are very mild in nature. However, they prevent ache by stopping pain messages from transmitting to brain. They raise the level of natural painkillers produced by the brain. The Tens Unit should only use under the instruction of a doctor, therapist or any physician. However, the medical use of Tens Unit is very save as it is non-invasive; reduce both acute and chronic pain. The results show that the high and low frequency Tens produce the effect by activating the periodic receptors in the central nerves system.
The high frequency Tens helps in producing the delta-opioid receptors in the spinal cord as well as in supraspinally with very low frequency. Whereas the low frequency Tens activates, beta-opioid receptors in the spinal cord as well as in the supraspinally.
The use of Tens Unit is very straightforward. Electrodes are attached to the surface of pain effective area or near that area. It is very important to place electrode in the right direction to that it works properly. Than the Tens Unit is operated. It should not be use across the cardiac pacemaker as it causes failure of implant device. On the areas of numb skin, it should be used with care as this part is already damaged and the device is very ineffective due to nerve damage. Some time patient may feel skin irritation because of inability to feel currents. There is risk involve in placing the Tens Unit on the effected skin area.
It is very necessary to change the batteries of device at time because the Tens may affect slow if batteries are not changed. The user can vary the controls and setting of device as frequency and voltage can change according to the severity of pain. It is also very necessary to set the proper duration of the simulation and intensity of the simulation. All the Health Care Products Canada also recommends Tens Unit.
