The Electrical Stimulation of Bone Formation.
In 1957 Fukada demonstrated that bone has piezoelectric properties, that is, bone produces electric current and potential in response to mechanical forces. The same phenomena were reported in 1962 by Bassett who found that the potentials developed in the area of compression were negative, and …

Toward the Optimal Waveform for Electrical Stimulation
<p>Electrical stimulation (ES) is used to strengthen muscle, improve abnormal tone, and improve the healing rate of pressure sores. Four male and three female research subjects received four minute bouts of electrically stimulated isometric contractions equal to 10% of the maximal voluntary …

Translational Modeling of Non-Invasive Electrical Stimulation
… the effect of low amplitude non-invasive electrical stimulation in people using neurophysiological measures (motor evoked potentials, MEPs). Clinical applications of transcranial Direct Current Stimulation (tDCS) have since proliferated, though the mechanisms are not fully understood. …

Biomimetic electrical stimulation for cardiac tissue engineering
… and function of the tissue being replaced. Electrical stimulation has been used to induce synchronous contractions of cultured cardiac constructs. The hypothesis adopted for this study is that functional cardiac constructs can be engineered by "mimicking" the conditions present during …

Control strategies for functional electrical stimulation induced cycling
Functional Electrical Stimulation cycling ergometers and mobile cycling systems have been developed over a number of years to allow Spinal Cord Injured persons to exercise. Standard able bodied exercise tests are adapted and applied to paraplegic cyclists. A modified recumbent tricycle is …

Novel mechanisms of DC and kilohertz electrical stimulation
<p>Transcranial electrical stimulation is a promising technique where a weak electrical current is applied to the scalp with the goal of modulating brain activity. Understanding the cellular mechanism of direct current (DC) and kilohertz (kHz) electrical stimulation is of broad interest in …

Modeling the electrical stimulation of peripheral vestibular nerves
… related disorders. The most likely sites of stimulation for the first-generation of such a device are the peripheral nerves responsible for transmitting rotational information to the brain. Although stimulation of such nerves has been performed in human and animal patients, little is known …

Paired Pulse Electrical Stimulation In Human Intractable Focal Epilepsy
… surgery were analysed, using paired pulse electrical stimulation. The amplitude of the response elicited from the first pulse (1st response) was compared with the amplitude of the response elicited from the second pulse (2nd response). Depending on if the 2nd response was absent, of …

Using electrical stimulation responses to understand cochlear implant status
… In this thesis, I investigate the use of CI electrical stimulation responses to assess CI status and the environment it occupies with regards to three issues that may affect CI performance and usage: extracochlear electrodes, facial-nerve stimulation, and cochlear fibrosis formation. In …

Nonlinear robust control of functional electrical stimulation system for paraplegia
… study was directed towards enhancing Functional Electrical Stimulation (FES) for sit-to-stand movement restoration in paraplegia subjects. The scarcity of FES assistive devices was due to the inability of the developed equipment to attain clinical acceptance. Applications of control systems have …

Using electrical stimulation for sensory restoration and modulation of attention
… For those suffering from sensory loss, electrical stimulation through auditory and visual prosthetics can be used to restore sensory abilities. In addition, sub-perceptual electrical microstimulation can be used to modulate top-down behavioral and attentional processes. This thesis …

A surface electrode array-based system for functional electrical stimulation
… to develop an electrode array-based functional electrical stimulation (FES) system for foot drop correction. The thesis reports a series of studies on the design and development of an electrode array, describes how these results informed the design of a practical array and demonstrates methods …

On the control of paraplegic standing using functional electrical stimulation
… cord injury (SCI) by the means of Functional Electrical Stimulation. In particular, the work presented in this thesis is concerned with unsupported standing, i.e. standing without any support by the arms for stabilisation. Firstly, the experimental apparatus and feedback control approach is …

Skeletal muscle pericyte response to acute and chronic electrical stimulation
… and gene expression in skeletal muscle following electrical stimulation, a method that can be used to simulate resistance exercise in mice. METHODS: Adult wild-type mice were subjected to an electrical stimulation protocol that results in 20 eccentric and 20 concentric contractions during a single …

Closed Loop Control of Muscle Contraction using Functional Electrical Stimulation
… treat patients with vocal fold paralysis using electrical stimulation is investigated throughout this research work. Functional Electrical Stimulation works by stimulating the atrophied muscle or group of muscles directly by current when the transmission lines between the central nervous system …
