OBJECTIVE To assess the effects of chronic knee pain on neural control of the nearby quadriceps muscle. METHODS Motor-evoked potentials (MEP) in response to transcranial magnetic stimulation (TMS) of the motor cortex, maximal M responses, patellar tendon responses, and EMG activity during maximal isometric contraction were recorded from the right vastus(More)
OBJECTIVES To determine the clinical usefulness of an electrophysiologic method for evaluating dysphagia and to identify the effects of various head and neck positions on oropharyngeal swallowing. DESIGN Experimental, with control group. SETTING An electromyography laboratory. PARTICIPANTS Patients with neurogenic dysphagia (n = 51) and healthy(More)
OBJECTIVE To assess the impact of post-polio-related fatigue on quality of life. DESIGN Cross-sectional case control study. SUBJECTS Patients without additional health problems that may induce fatigue were selected from among 82 polio survivors. Twenty-six patients with post-polio syndrome and 10 without post-polio syndrome were included. Control group(More)
Thirty-three children with idiopathic nephrotic syndrome who underwent kidney needle biopsy were reevaluated. The male to female ratio was 2:1, and a preponderance of North-African Jewish and Arab origin over Ashkenazi Jewish origin was noted. There was a positive correlation between the severity of glomerular changes and prognosis among the 10 cases with(More)
Locally acting treatments for spasticity such as nerve and motor point blocks have the advantage of reducing harmful spasticity in one area, while preserving useful spasticity in another area. This randomized, double-blind study is the first trial that was designed to find out whether botulinus toxin Type A and phenol relieves the signs and symptoms of(More)
This preliminary study was designed to investigate the effects of botulinus toxin Type A and phenol treatments on electrophysiologic tests evaluating spinal afferent and efferent motor pathways involved in spasticity. The questions posed were whether different types of mechanisms act on reducing spasticity with these different treatment modalities and(More)
PURPOSE The effectiveness of an appliance for the treatment of obstructive sleep apnea (OSA) shows inordinate interindividual differences. Also, its therapeutic effects still remain unresolved. This study examined and compared the effects of a mandibular advancement splint (MAS) on the masseter and submental muscles of patients with mild and moderate OSA.(More)
OBJECTIVES To demonstrate a clear-cut M response recorded from the severely affected thigh muscles to the stimulation of the upper limb nerves in a serial of patients with late poliomyelitis. METHODS Fifteen patients with late poliomyelitis, 7 patients with spinal cord disorders and 11 control subjects were included. Evoked muscle responses were(More)
Paralysis after use of a tourniquet during surgery is a well recognized complication. Based on the electrophysiologic findings, 35 cases referred to our electromyography laboratory have been diagnosed as tourniquet paralysis within a 3-yr period. This preliminary report suggests that tourniquet paralysis should be considered during clinical and(More)
