Abstract :

Pain is an important physiological phenomenon that occurs from birth to the last stages of life. Pain is one of the causes of the patient's referral to clinics and treatment centers. Pain control is one of the major challenges for surgeons and anesthesiologists. Lack of proper pain control lead to hospital­ization and imposes higher treatment costs for patients and hospitals. It causes dissatisfaction with the medical treatment and frequent visits to medicians to control the pain. Medication is not only way for pain reduction; depending on the cause and type of pain, other ways can employ. Electrical stimulation of nerve pain inhibitors through the skin (TENS) is a noninvasive technique to relieve pain. During TENS, pulsed electrical currents are administered across the intact surface of the skin to generate strong nonpainful TENS sensations or mild muscle twitching at the site of pain. This technique inhibits onward transmission of nociceptive (pain-related) information in the central nervous system and appears to be beneficial for acute and chronic pain. In the present study, the effect of TENS on different types of pain investigated and positive outcomes in muscu­los­keletal relief and post-operative pain suggested, although many systematic reviews were inconclusive.
