In electrotherapy applications, Transcutaneous Electrical Nerve Stimulation (TENS) is defined as a method of applying high-frequency low-intensity electric current to the nervous system through superficial electrodes placed on the painful area or the nerve innervating that area, used all over the world in the treatment of pain, FDA approved in the United States.
Its effectiveness is thought to be the result of a combination of effects such as stimulation of large-scale afferent fibers that inhibit the activity of primary afferent pain neurons or endogenous opioid-dependent mechanisms including the release of dynorphins, enkephalins and endorphins in the central nervous system .
Interferential current are medium frequency currents. The analgesic effect of this current is based on the gate control theory. The disadvantage compared to TENS is that it provides lower neural adaptations with higher currents.
As a result of this study, it is thought that the determination of effective treatment methods for pain, which is one of the common symptoms of MS patients, will increase the functional capacity and quality of life of the patient.
In the study, patients who meet the inclusion criteria will be divided into 2 groups by randomization, TENS will be applied to the 1st group, and interference current will be applied to the 2nd group. Applications will be applied for 4 weeks, 5 days a week. Evaluations will be made by a blind physiotherapist twice, before and after the treatment. Assessments include sociodemographic information, pain, functional capacity, and quality of life.
In addition to the studies in the literature, this study will be the first to compare the effectiveness of different electrical stimulations in pain in MS.
