Inter-rater reliability of motor unit number estimates and quantitative motor unit analysis in the tibialis anterior muscle.
OBJECTIVE To establish the inter-rater reliability of decomposition-based quantitative electromyography (DQEMG) derived motor unit number estimates (MUNEs) and quantitative motor unit (MU) analysis. METHODS Using DQEMG, two examiners independently obtained a sample of needle and surface-detected motor unit potentials (MUPs) from the tibialis anterior muscle from 10 subjects. Coupled with a ma...
متن کاملSingle-motor-unit discharge characteristics in human lumbar multifidus muscle.
The underlying neurophysiology of postural control of the lower back in humans is poorly understood. We have characterized motor unit (MU) discharge activity in the deep lumbar multifidus (LM) muscle in nine healthy subjects (20-40 yr, 3 females). Bilateral fine wire electrodes were implanted at L4 spinal level using ultrasound guidance. EMG was recorded during spontaneous sitting and standing ...
متن کاملMotor Unit Characteristics after Targeted Muscle Reinnervation
Targeted muscle reinnervation (TMR) is a surgical procedure used to redirect nerves originally controlling muscles of the amputated limb into remaining muscles above the amputation, to treat phantom limb pain and facilitate prosthetic control. While this procedure effectively establishes robust prosthetic control, there is little knowledge on the behavior and characteristics of the reinnervated...
متن کاملInvestigation of motor unit recruitment during stimulated contractions of tibialis anterior muscle.
This work investigated motor unit (MU) recruitment during transcutaneous electrical stimulation (TES) of the tibialis anterior (TA) muscle, using experimental and simulated data. Surface electromyogram (EMG) and torque were measured during electrically-elicited contractions at different current intensities, on eight healthy subjects. EMG detected during stimulation (M-wave) was simulated select...
متن کاملSingle - motor - unit discharge characteristics 1 in human lumbar multifidus muscle
25 The underlying neurophysiology of postural control of the lower back in humans is 26 poorly understood. We have characterized motor unit (MU) discharge activity in the 27 deep lumbar multifidus (LM) muscle in 9 healthy subjects (20–40 years, 3 females). 28 Bilateral fine wire electrodes were implanted at L4 spinal level using ultrasound 29 guidance. EMG was recorded during spontaneous sittin...
