A comparison of neuromuscular electrical stimulation parameters on increasing corticospinal excitability
DownloadFall 2013
In this thesis, experiments that investigated the effects of neuromuscular electrical stimulation (NMES) parameters on corticospinal (CS) excitability are described. The NMES-induced afferent volley can increase CS excitability, which can facilitate neurorehabilitation. However, literature...

This thesis describes experiments designed to investigate the effects of neuromuscular electrical stimulation (NMES) on corticospinal (CS) excitability in humans. NMES delivered at 100 Hz was more effective for increasing CS excitability than 10-, 50-, or 200-Hz NMES. CS excitability increases...

Contraction fatigue and motor unit overlap in the tibialis anterior during different intensities of interleaved electrical stimulation
DownloadSpring 2018
Interleaved neuromuscular electrical stimulation (iNMES), which involves alternating stimulus pulses between a nerve (nNMES) and muscle belly (mNMES), has been demonstrated to reduce fatigue of the ankle dorsiflexors when used with relatively low contraction amplitudes. However, the amount of...

Decreases in the excitability of motor axons contribute substantially to contraction fatigability during neuromuscular electrical stimulation
DownloadFall 2017
Activity-dependent changes in axonal excitability are well-documented, yet the contribution to contraction fatigability during neuromuscular electrical stimulation (NMES) is unclear. The present study was designed to: 1) characterize the magnitude and time course of changes in motor axon...

Does stimulus pulse width influence contraction fatigability during neuromuscular electrical stimulation?
DownloadFall 2019
Neuromuscular electrical stimulation (NMES) is used to generate contractions of muscles for rehabilitation after injury or disease to restore functional movements or reduce secondary complications of disuse. However, due to the unnaturally high discharge rates and random recruitment order of...

Neuromuscular electrical stimulation (NMES) is a common therapeutic tool for persons with movement disorders. The manner in which NMES generates muscular contractions has traditionally been attributed to the depolarization of motor axons underneath the stimulating electrodes, a purely peripheral...

Fall 2010
In this thesis sensorimotor integration in the human spinal cord was investigated in the intact (Chapters 2 and 3) and injured nervous systems (Chapter 4-stroke; Chapter 5-spinal cord injury (SCI)). In Chapter 2, I characterized a short-latency reflex pathway between sensory receptors of the...

Where electrical stimulation is delivered affects how contractions are generated in the tibialis anterior muscle
DownloadFall 2012
This thesis describes experiments designed to investigate how motor units in tibialis anterior (TA) were recruited when electrical stimulation was applied over the TA muscle belly versus the common peroneal nerve trunk. The data from the first study (Chapter 2) showed that contractions were...
