Surgeon directed transcranial motor evoked potential spinal cord monitoring in spinal deformity surgery: A review of viability, safety and efficacy
… surgeon directed intra-operative transcranial motor evoked potential (TcMEP) monitoring a useful compromise. Our experience using surgeon directed TcMEP is presented in terms of viability, safety and efficacy. Methods A retrospective review was performed on a single surgeon's prospectively …

Stimulus parameters influencing cortical responses by transcranial magnetic stimulation targeting I-wave dynamics : duration, intensity and interval between interventions
… magnetic stimulation (TMS) modulates corticomotor excitability and plasticity; however, the magnitude of the effects appears to depend on a range of stimulus parameters. Three possible critical factors of repetitive TMS (rTMS) interventions are the duration of application, the intensity of …

Impact of Pelvic Floor Dysfunction on Quality of Life in Cancer Survivors and Development of Pelvic Floor Muscle Rehabilitation Program
… muscle strength and higher rise in amplitude of motor evoked potential at sacral stimulation than in the control group. Conclusions: Gynecological cancer and treatment procedures cause important problems that have a negative effect on quality of life. Pelvic floor dysfunction improved after PFRP …

Comparison of muscle synergies elicited from transcranial meganetic stimulation (tms) and voluntary movements
A key question in motor control is the redundancy of musculoskeletal elements involved. This problem refers to as the degree of freedom problem. The Muscle Synergy Hypothesis is one of the hypotheses that aim to resolve the problem which defines that a muscle synergy is a combination of a small set …

The Immediate Effects of Electromyographic Biofeedback on Corticomotor Excitability of the Quadriceps in Healthy Individuals
… bout of electromyographic biofeedback on corticomotor excitability in healthy individuals. Design: A cross- over study with a one-week period between each testing session was conducted in a laboratory setting. Participants: Twelve participants (6 male, 6 female; 21.41 ± 4.41 years; 172.82 ± 11.23 …

A compositional framework for quantifying neurophysiological motor recovery after stroke
… explores peri-threshold activation of the corticomotor pathway from transcranial magnetic stimulation-derived motor evoked potentials (MEPs) by characterising suprathreshold, subthreshold, and subliminal responses based on conventional resting threshold criteria. A review of current transcranial …

Die Entwicklung des corticospinalen Systems zur Hand : Beiträge der transcraniellen Magnetstimulation und motorischer Funktionstests
… Ausdruck in einer zunehmend leistungsfähigeren Motorik. Als humanspezifisch werden die Bewegungen der Hand angesehen, die in hohem Maße durch das corticospinale System kontrolliert werden. Dessen Funktion ist durch die transkranielle Magnetstimulation (TMS) darstellbar. <br>Mittels TMS und …

Neuromuscular characteristics of eccentric contractions of the knee extensors and their muscle damage profiles
… to examine inhibitory responses in the primary motor cortex representation of the quadriceps, but appropriate pairedpulse transcranial magnetic stimulation (TMS) parameters to optimise SICI measurement were not clear. Using 9 men and 6 women (26.6 ± 4.4 y), responses to single and paired-pulse …

Neuromuscular factors contributing to reductions in muscle force after repeated, high-intensity muscular efforts
… to Experiment 1. Significant reductions in the evoked torque response from 20 Hz (p < 0.001), 80 Hz (p < 0.001) and VFT (p < 0.001) stimulations were observed at POST and did not recover by POST-20, however no changes in 20:80 and 20:VFT ratios were observed. Finally, significant reductions in …

Einfluss verschiedener transkranieller Stimulationsverfahren auf die kortikale Exzitabilität
… Stimulation wurde durch eine EMG-Ableitung der motorisch evozierten Potentiale am betreffenden Muskel quantifiziert und in festen Abständen (0, 5, 10, 20, 30, 40, 50, 60, 90 Minuten) mittels Einzelpuls-TMS kontrolliert. Die Analyse der EMG-Daten zeigte, dass alle drei Stimulationsarten die …
