Electrical therapy is part of physical therapy in the form of electrical stimulation. Included in these symptoms are lower or upper back pain, pain when moving, headaches, tingling until the sensation is lost or vice versa, it becomes very sensitive. In dealing with neurological diseases, this therapy is thought to work by sending electrical signals and stimulating disrupted nerves so as to inhibit or reduce pain and inflammation, as well as improve muscle function and strength, as well as blood circulation. Other theories also argue that electrical stimulation released into the nerves by using an electrical stimulation machine during therapy pushes the body to produce more endorphins or natural painkillers.
Usually, a light stroke can be helped. Each person is different. If a heavy stroke has been difficult for many years, it needs a process. Even so, until now physical therapists have also questioned whether electrical therapy is really needed.
It’s because the treatment through electrical therapy is relatively passive and the patient almost does nothing while the therapy is applied.
Meanwhile, the most successful treatment programs are known to be determined by the active participation of patients. Learning the right movements and exercise for a patient’s specific condition is the key to healing.
Several types of electrical therapy include Transcutaneous Electrical Nerve Stimulation (TENS), Percutaneous Electrical Nerve stimulation (PENS) or electroacupuncture, Deep Brain Stimulation (DBS) which requires surgery, and Repetitive Transcranial Magnetic Stimulation (rTMS).
TENS is an alternative type of electrical therapy that is most often used since it was first developed in the late 1960s. TENS is also often regarded as the only electrical therapy by the laity, and other electrical therapies such as electroacupuncture are its derivatives.
The way TENS works is by utilizing low-voltage electrical conductors such as home electricity to ease the pain. How it works is quite simple. It works by using a switch that is fitted with two electrical wires and connected to two metal rods of tin or aluminum as a terminal.
The two metals are placed on the floor covered by carpet or materials that do not conduct electricity, then covered with a wet cloth. The patient is asked to step on one cloth, and the therapist will step on the other cloth while regulating the amount of electric current that is delivered to the patient’s body.
However, most showed conflicting results and needed further research. While there are benefits, such as relief of rheumatoid arthritis pain in the hands and osteoarthritis in the knee, only come from small studies.
One fact is certain, TENS and other electrical therapies do not cure pain or treat the underlying problem, although many people recognize that this kind of electrical therapy can relieve short-term pain and find its use beneficial, even if the pain returns.
