How Do TENS Machines Work?
Few options are more effective than Transcutaneous Electrical Nerve Stimulation (TENS) when it comes to treatments for back pain. TENS machines have been proven as an effective relief method by many clinical studies. Zoe Tech Australia TENS machine operates on the same principle as having a low level of current applied to the skin. However, instead of using direct electrical current to the skin, the TENS machine applies a constant low-level source of stimulation. The goal of this treatment is to provide relief from pain without invasive procedures like surgery.
The TENS machine works on two principal theories – that a patient experiences a tingling sensation when the electrodes are placed over the area of pain, and a corresponding sensation occurs when the electrodes are removed. Based on these theories, the machines are designed to provide a continuous and pulsating sensation that provides relief from chronic pain. As a result, some physicians may recommend that Zoe Tech Australia TENS machine be used in conjunction with other therapies to provide faster relief from chronic pain. While this may seem like good news, the primary function of the tingling sensation is to relieve pain and not to treat any medical condition. It means that the tingling sensation is not a cure, and it has been considered ineffective by some researchers.
Zoe Tech Australia TENS machine uses small electrodes that are attached around your body. These electrodes do not cause injury or permanent tissue damage. The theory behind applying the electrodes is that you will feel a tingling sensation when the electrodes are placed over the pain site. Still, that sensation will subside when the electrodes are taken away. A wide variety of equipment is used to feel like; muscle relaxation, heat, cold, ultrasound, and pressure. Many people use tens machines along with other therapies like aromatherapy and acupuncture for pain relief.
Patients who use this type of machine have reported relief from symptoms associated with chronic joint pain like neck, shoulder, hip, joint pain, fibromyalgia, and back pain. Some patients find that using the tens machines alongside other therapies such as acupuncture and massage has produced better results than the traditional methods. However, most experts agree that it is still unclear how electrical nerve stimulation works to relieve pain effectively. Therefore, it is still unclear whether the machine provides a beneficial relief for chronic pain or if it simply aggravates pain already present.
Although the tingling sensation caused by the application of the electrodes appears to be the critical factor, some experts have claimed that it may not be the sole contributing factor to the relief. According to them, the actual stimulation of the nerve may not be the only beneficial effect of the electrical impulses. They argue that the direct electrical current also causes changes in certain chemicals or the nervous system, directly affecting the nerve. In addition, even the stimulation of a smaller region of the nerve can result in different local effects, which is not local to the area of application.
