Sensitivity of the Median- Ulnar Motor Comparative Techniques in Carpal Tunnel Syndrome
ABSTRACT Carpal Tunnel Syndrome is the most common entrapment syndrome. Median-ulnar motor comparative technique with Median motor technique in carpal tunnel syndrome were studied. In 50 patients with 72 hands with clinically defined carpal tunnel syndrome and electrophysilogic evidence of Median neuropathy at wrist based upon a prolonged sensory nerve distal latency with 30 asymptomatic volu...
متن کاملMotor Unit Number Estimation and Motor Unit Action Potential Analysis in Carpal Tunnel Syndrome
OBJECTIVE To evaluate the clinical significance of motor unit number estimation (MUNE) and quantitative analysis of motor unit action potential (MUAP) in carpal tunnel syndrome (CTS) according to electrophysiologic severity, ultrasonographic measurement and clinical symptoms. METHOD We evaluated 78 wrists of 45 patients, who had been diagnosed with CTS and 42 wrists of 21 healthy controls. Me...
متن کاملThenar motor unit count estimates in the carpal tunnel syndrome.
Thenar motor unit counts were done in 19 subjects with symptoms characteristic of the carpal tunnel syndrome. Three-quarters of the patients had motor unit count estimates less than 2 SD lower limit of controls. Despite this, most did not have thenar wasting or weakness. Functional compensation by motor unit remodelling probably kept pace with motor axon loss and masked the true extent of axona...
متن کاملSpontaneous rhythmic motor unit potentials in the carpal tunnel syndrome.
In 18 out of 164 consecutive patients with carpal tunnel syndrome ongoing spontaneous rhythmic motor unit potentials were found in the lateral thenar muscles. The frequency ranged from 3 to 9 Hz with an average of 6 Hz. The spontaneous rhythmic motor unit potentials appeared to be doublets in many cases. Ischaemia usually caused a marked increase of spontaneous activity within 1 to 2 minutes. D...
متن کاملMotor amplitude of median nerve with stimulation in the palm a reliable indicator for axonal loss in carpal tunnel syndrome
Background and Aim: The present study aimed to use the median nerve compound muscle action potential (CMAP) amplitude by stimulation at the palm instead of abductor pollicis brevis (APB) needle electromyography (EMG) for determining a sign of axonal loss in patients with carpal tunnel syndrome (CTS). Methods and Materials/Patients: This study was performed on 180 patients with CTS referred to ...
