the objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. in a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. this time indicates the basal response of vestibular end-organ. after caloric irrigation, pulsed signal was applied for each pers...
Objectives: One of the most common and disabling complications that affects individuals with spinal cord injury is spasticity. The purpose of this study is to compare the effect of agonist and antagonist electrical stimulations on triceps surae muscle spasticity in patients with spinal cord injury. Methods: A total of 30 subjects with spinal cord injury were considered for the study. They were...
Objective: Myofascial pain syndrome is a common disorder with a prevalence of up to 85%. It is characterized by the presence of trigger points, which all people are commonly encountered at least once throughout their lifespan. Different physical therapy and medical treatments have used to manage myofascial pain syndrome. Intramuscular electrical stimulation intervention is a relatively new trea...
The previous studies have shown that the endogenous opiate system depress the baroreflex sensitivity in morphine dependent persons. Nucleus Tractus Soloitarii(NTS) is the main termination site of baroreceptor afferent neurons. The aim of this study was to determine the role of electrical stimulation of Nucleus Tractus Soloitarii on baroreflex sensitivity in morphine...
Introduction: Opiates cause dependency via affect on central nervous system. Locus coeruleus nucleus is a main group of noradrenergic neurons in the brain that plays an important role in the expression of opioid withdrawal signs. During opioid withdrawal, brain waves change in addition to physical and behavioral signs. In this study, we examined the effects of locus coeruleus electrical sti...
Introduction: Postoperative hemodynamic monitoring by nurses provides accessible information about the patient's cardiovascular function. Patients often experience the vital signs increase due to the activation of sympathetic system. The aim of this study is to compare the effect of Transcutaneous Electrical Nerve stimulation (TENS) in acupuncture points with the incision site on physiologic pa...
background : this study evaluated the sensation of palatal ucosa before and after le fort i osteotomy and compared it based on whether greater palatine nerve has been dissected or not. methods : sixteen patients were studied within one week before urgery and then one week, 6 weeks, 3 months and 6 months after surgery. four tests including sharp-blunt discrimination, cold perception, pin prick ...
abstract introduction: interferential current is one of the most popular kinds of electrical stimulation that are used in electrotherapy. despite its clinical popularity, there have been limited studies to investigate how this stimulation protocol affects the nerve fibers. this study was aimed to develop a realistic model for the stimulation of nerve fibers by interferential currents and using ...
in this paper, a control strategy is proposed for control of ankle movement on animals using intraspinal microstimulation (isms). the proposed method is based on fuzzy logic control. fuzzy logic control is a methodology of intelligent control that mimics human decision-making process. this type of control method can be very useful for the complex uncertain systems that their mathematical model ...
