In the medical field, there are different branches that deal with different areas of Human health. The branch that deals with muscles and movement of the body is called as Physiotherapy. Electrotherapy or electro physiotherapy is mainly utilized in physical therapy to relax muscle spasms, retardation of disuse of atrophy and its prevention, muscle rehabilitation, increase in local blood circulation, muscle stimulation, re-education electrical muscle stimulation, management of chronic and intractable ailments, maintaining and enhancing the range of motion.
Electro physiotherapy equipment is a well-known modality that is employed in rehabilitation and physical therapy. Electrical muscle stimulation also known as electrotherapy makes use of an electrical machine that is utilized for delivering electrical impulses to the body of a patient. The stimulation is undertaken in a way so that it supports and makes possible tissue regeneration and muscle healing. Electrotherapy is not only considered an accepted modality in case of physical therapy, but it is also utilized in other rehabilitation practices as it has many other therapeutic benefits.
Electro physiotherapy has shown to help in many conditions as given below.
It relaxes muscle spasms, improves local blood flow and circulation, prevents and cessation of atrophy of muscles due to disuse. It also preserves and improves range of movement and motion, and re-educates muscles utilizing targeted stimulation, prevents deep vein thrombosis caused in post-surgery, and management and minimisation of pain( as chronic, post-traumatic, and post-surgical acute). It is also used in improvement in the efficacy in providing prescription drugs- electromotive drug administration; facilitates wound healing.
Working of Electrical Stimulation Therapy
Electrotherapy Equipment Physiotherapy or electrotherapeutic machines and devices present varied therapeutic waveforms. In an electrical stimulation machine there are found electrodes which are made to connect to the area to be treated, and as they are activated, the electrical energy passing through the electrodes makes the muscles to contract. The contraction of the muscles copies the natural movement of the body during activity and as such prevents atrophy of muscles.
The most widespread waveforms that are present in electrical stimulation are as:
TENS, Russian, interferential, Pre-modulated, Biphasic, High voltage, and Micro-current. All these waveforms have their specific therapeutic benefits. So it is clear that varied devices give the practitioner multiple kinds of waveforms that could be used on different patients according to the need and what they require.
The different kinds of waveforms utilized in electrical stimulation therapy (e-stim) are made to target the area to be treated and specific body part and impart modified types of energy transfer. This diversity in energy transfer assists to deliver different therapy needs.
Transcutaneous Electrical Neural Stimulator (TENS)
Tens works to minimise pain as it blocks pain signals that would otherwise reach the brain. The stimulation caused to TENS also facilitates the production of endorphins. It is a well-known waveform to treat back pain and neck pain.
It delivers medium frequency that is in alternating pulses of energy. This has become popular waveform to re-educate specific areas and enhance muscle strength. It also stimulates the release of endorphins.
