“…To date, there are only four publications on normative electromyography data of the patellar reflex, none of which was conducted during pregnancy and only one of which examined the vastus medialis muscle . The first purpose of the present study was to define reference values of the CMAP of the vastus medialis muscle in healthy pregnant women using SEMG and to determine whether the patellar reflex is affected by normotensive pregnancy.…”

“…central fatigue and peripheral neuromuscular fatigue. In contrast to the conventional fatigue test induced by MVCs, externally applied electrical or magnetic stimulations for peripheral nerve roots that measure the CMAP after stimulation have long been known to evaluate peripheral neuromuscular function [16,17]. CMAP measures the peripheral neuromuscular fatigue (especially neurotransmitters) in the muscles bypassing the central nervous system.…”

“…Stimulations were delivered with the maximal output of the stimulator. Subjects were asked to keep their neck slightly bent forward for stimulating the phrenic nerve [16], while lying on the Cybex table with the coil placed below the inguinal ligament and 2 cm laterally from the femoral artery for stimulating the femoral nerve [17].…”

Repetitive inspiratory effort against an obstructed airway and intermittent hypoxia may be deleterious to the inspiratory muscles in patients with obstructive sleep apnoea (OSA).We investigated muscular dysfunction by comparing the strength, endurance and fatigability of inspiratory muscles and knee extensors in patients with newly diagnosed severe OSA compared with matched controls. The measurements included strength and endurance tests of both muscles, and a fatigue trial with simultaneous surface electromyography of the diaphragm and the vastus lateralis during voluntary contractions and in response to magnetic stimulation. To our knowledge, this is the first investigation to assess peripheral muscle performance in severe OSA patients versus controls.Patients in the OSA group exhibited significantly lower strength and endurance in both muscles than the control group. The fatigue index decreased significantly exclusively in the inspiratory muscles of OSA patients. Magnetic stimulation-evoked compound muscle action potential latencies increased and the amplitudes decreased significantly in the diaphragm, but not in the vastus lateralis after a fatigue test in the OSA group.In conclusion, a significantly lower functional performance was shown for both inspiratory muscles and knee extensors in the OSA group. However, higher fatigability was only seen in the inspiratory muscles of patients with severe OSA.
