Background: The pneumatic tourniquet (PT) is routinely used in upper and lower limb operations by most orthopaedic surgeons. The silicone ring tourniquet (SRT) was introduced in clinical practice the last decade. Clinical as well comparative studies in volunteers concerning its safety and efficacy have been published. The aim of this study was to investigate the postoperative effect of the si...

The surface electromyogram (EMG) comprises the sum of the electrical contributions made by the active motor units to the interference signal detected by electrodes placed on the skin overlying the muscle. Because it provides a global measure of motor unit activity, this signal is a valuable tool for assessing the level of muscle activation. The analysis of the surface EMG in the frequency domai...

BACKGROUND/AIM The aim of this study was to electrophysiologically evaluate the effect of increased intraabdominal pressure (IAP) on genitofemoral nerve (GFN) motor conduction. MATERIALS AND METHODS Seven Wistar albino rats were included. After anesthetization, latency and duration of GFN conduction was recorded with a needle-probe at rest. IAP was increased to 15 mmHg by insufflating atmosph...

Reports on measurement of muscle fiber conduction velocity in humans are scarce. Inferences on the behavior of conduction velocity have been drawn from the behavior of myoelectric spectral parameters. The present report contains information on conduction velocity and spectral parameters studied at various muscle contraction levels and during and after sustained contractions. The following resul...

OBJECTIVE To confirm the reported findings and clarify unknown clinical features of Churg-Strauss syndrome (CSS)-associated neuropathy and design appropriate treatment. PATIENTS AND METHODS We assessed the clinical features of 6 patients with CSS-associated neuropathy. RESULTS Mononeuritis multiplex was present in 4 cases and polyneuropathy in the remaining cases. Both groups progressed to ...

In this study we examined motor and sensory conduction velocities in right median and ulnar nerves in diabetic patients. Control group consisted of 25 healthy volunteers (13 males) with average age of 52 years. The first examined group consisted of 25 diabetic patients (13 males) without retinal changes, 59,6 years old on average, and the second group consisted of 40 patients (15 males) 59,4 ye...

Objective: The aim of present study was to evaluate the effects of oral administration of gallic acid (GA) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. Materials and Methods: Seventy adult male Wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) Control (Cont), 2) Cru...

Hereditary canine spinal muscular atrophy (HCSMA) is an autosomal dominant degenerative disorder of motor neurons. In homozygous animals, motor units produce decreased force output and fail during repetitive activity. Previous studies suggest that decreased efficacy of neuromuscular transmission underlies these abnormalities. To examine this, we recorded muscle fiber endplate currents (EPCs) an...
