To develop a database of normal values for muscle thickness and echo-intensity in American children and adults. Quantitative Muscle Ultrasound – Normal values and Development of a Neuromuscular Disease Database.The primary aim of this clinical investigation is to examine a prototype of a quantitative monitoring instrument that will meet most, if not all, of the clinical requirements. Electrophysiological Comparison of mAP and mADM Using EMG.The purpose of this study is to assess the onset of neuromuscular blockade and recovery profiles of aminosteroidal neuromuscular blocking agents (NMBAs) after sugammadex at the flexor hallucis brevis (great toe) and adductor pollicis (thumb) muscles.


A Study to Compare Neuromuscular Monitoring of The Thumb and Great Toe Muscles with Electromyography.The purpose of this study is to get performance data on the TetraGraph, to see if it is an easy-to-use and accurate quantitative neuromuscular monitor, by testing it on normal volunteer adults. A Study of the Performance of the TetraGraph for Electromyographic Assessment in Normal Volunteers.The primary purpose of this study is to establish a proof of concept that electrical stimulation within the operative field can attenuate corpus cavernosum electromyography (CC EMG) activity. A Study to Determine the Feasibility of Neurophysiological Cavernous Nerve Mapping During Prostate Surgery.The purpose of this study is to correlate the objective electromyography (EMG)-derived data (TOFR, TOFC, PTC) with subjective (blinded) evaluation of responses using the TetraGraph. A Study to Compare Visual and Electromyography Assessments of Train-of-Four Stimulation of the Ulnar Nerve.The aim of this study is to determine whether EMG monitoring in the operating room reduces the incidence of postoperative residual blockade (measured at the time of tracheal extubation and on arrival to the PACU). A Study About a Device that Measures Muscle Relaxation in Patients Receiving Muscle Relaxing Medications during Surgery.The purpose of this study is to determine if the near-infrared spectroscopy (NIRS) and electromyography (EMG) signal during isometric handgrip exercise is reproducible within subjects (for the same and different limbs) and between subjects. Intra and Inter-subject Reliability of Near-infrared Spectroscopy (NIRS) During Exercise.The purpose of this study is to examine test-retest reliability of measurements obtained with cross recurrence quantification analysis with respect to (A) dynamic hip-knee motion coupling patterns and (B) gluteus maximus-gluteus medius EMG recruitment coupling patterns during single-limb step-downs. Study of Test-retest Reliability of Hip-Knee Joint and Gluteus Maximus-Gluteus Medius Recruitment Coupling Pattern Measures Obtained with Cross Recurrence Quantification Analyses.
