the purpose of the this study was to investigate the effect of direct current on montoneuron reflex exitability. thirty six subjects (18 males, 18 females) 19.36 years of age ( x= 24.06, sd= 3.63) participated in this study. the reflex excitability of soleus motoneruons was assessed by measuring the amount of change in the peak to peak ampitude of the h-reflex before and after direct current wa...

purpose: to evaluate the incidence of the oculo-cardiac reflex (ocr) and its associated risk factors during strabismus surgeries performed at a tertiary referral center between 1390 and 1392. methods: over a 2-year period, all strabismus surgery candidates were enrolled in the study after obtaining consent from the patients or their parents. vital signs were recorded before the initiation of th...

purpose : to report a case of recurrent corneal intrastromal cyst containing lymph fluid case report : a 13-year-old girl presented with recurrent cyst of the left cornea, which had been drained three years before, but had gradually recurred. the cyst was successfully drained. histologic examination, cytologic analysis, and protein electrophoresis were performed on the cyst fluid. histopatholog...

Diabetes mellitus has been identified as a risk factor for dry eye syndrome (DES). The prevalence of DES in diabetes has been reported to be up to 54.3% (1). DES compromises quality of life because it induces ocular discomfort and visual disturbance and may be complicated by corneal epithelial defects, erosions, or ulcers. Therefore, it is recognized as a growing public health problem that shou...

purpose: oculocardiac reflex (ocr) is a frequent event during strabismus surgery. the aim of this study is to compare the preventive effect of intravenous lidocaine and hyoscine on ocr.methods: this prospective, randomized clinical trial was performed on 75 patients (5-63 years old) underwent strabismus surgery. patients divided randomly into three groups. intravenous hyoscine (0.2 mg/kg), lido...

background: h-reflex is a valuable electrophysiological technique for assessing nerve conduction through entire length of afferent and efferent pathways, especially nerve roots and proximal segments of peripheral nerves. the aim of this study was to investigate the relation between normal values of flexor carpi radialis (fcr) h-reflex latency, upper limb length and age in normal subjects, and t...

normal 0 false false false en-us x-none ar-sa background: the h-reflex is a useful electrophysiological procedure for evaluating the status of the peripheral nervous system, especially at the proximal segment of the peripheral nerve. the purpose of this study is to investigate the relation between triceps surae h-reflex and m- response latencies and thigh length in normal population, in order t...
