A TENS machine or electronic unit is a very small electronic unit, most often battery operated, treating both chronic and acute pain. The unit usually has two cables attached to flexible electrodes placed directly on the human skin. The electrodes provide low voltage electric impulses to targeted body parts to trigger pain signals within the body to prevent pain from surfacing. Patients find that using a TENS machine is highly effective at reducing pain and other unpleasant symptoms associated with arthritis and fibromyalgia.
Patients who use these types of therapeutic units can use them anywhere at any time. Because of the unit’s mobility, the patient does not have to be bound to a bed, chair or any other stationary object. In addition, the TENS machine Australia can be used by people of all ages, although younger patients more commonly use it.
Electrodes are attached to the unit to send low-level electrical impulses and the two cables to the selected body part. When the patient moves their arm, the electrical impulses trigger the machine to make the electrical impulses known as “pain signals.” As the patient moves the arm, the machine detects this movement and sends the pain signal to the nervous system. When the person relaxes, the tens machine detects that relaxation and the reduction in sensation cause the electrical impulses to stop. The pain signal is sent back down the two cables to the machine’s electrode connector.
Patients have many different applications for TENS machine Australia. Some use the device for pain management, while others use it for stress and tension reduction. TENS machines also serve as aids to help those suffering from spasticity. Many patients with multiple sclerosis and other debilitating diseases find that using a TENS unit at night helps them fall asleep. They do not wake up feeling as stimulating as they did before using the machine.
Some of the health conditions that may cause someone to need a tens machine include muscle spasms, circulatory problems and some types of arthritis. Muscle spasms can lead to painful cramps that can interfere with daily activities. Circulatory problems may cause hypertension or high blood pressure. Some people suffer from muscle weakness and tautness that makes moving the fingers difficult. This problem is also treated by having the patient stimulate the muscles with the tens machine.
The benefits of using a TENS machine are numerous. Some of these are as follows: The patient can reduce or eliminate the need for drugs or creams to achieve relief from muscle pain and other symptoms; relaxation of the muscles helps to restore range of motion exercises to improve the health of the tissues surrounding the muscles; relaxing the skin may help reduce skin cancer; electrotherapy has been proven to reduce inflammation and stiffness in joints, and TENS does not damage the skin or the nerves. However, some side effects of using a transcutaneous electrical stimulation device have been identified. These side effects include numbness in the hands, feet or any part of the body; headaches, tingling, dizziness, lightheadedness and other sensations. In some cases, patients have been known to develop an addiction to the electrical current produced by the machine.
The main components of a transcutaneous electrical stimulation machine are electrodes, a base and a ring or other outer covering. Electrodes are the actual wires that capture the blood flow and transmit the signal to the transcutaneous pads. The pad is fitted to the patient’s skin, and the patient places their hands or any other part of their body on top of the pad. The pads are then attached to metal or plastic frames that rest on the skin. There is also a small cord attached to the top of the frame.
The TENS machine works by sending low-level electrical pulses along with the hair roots of the nerve endings. This signal stimulates the nerves passing through this area, causing the nerves to produce relaxing and pleasurable sensations that relieve pain. Some electrical impulses actually travel to the brain, which interprets the pain signals and corrects them by sending appropriate chemicals. However, the pain signals are not very strong when they reach the brain, and this is why most TENS machines are not used for acute pain such as arthritis and some forms of chronic pain such as fibromyalgia. TENS machines are mainly used on people with chronic conditions or pain who cannot receive relief from other treatment forms.
