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 …

Nonlinear robust control of functional electrical stimulation system for paraplegia
The 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 …

A surface electrode array-based system for functional electrical stimulation
… thesis is 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 …

On the control of paraplegic standing using functional electrical stimulation
… after spinal 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 …

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 …

The production and control of functional electrical stimulation swing-through gait
… in the synthesis of swingthrough gait by functional electrical stimulation (FES). A general introduction is given to paraplegic gait, then the following areas are reviewed in detail: previous production of FES swing-through gait; biomechanical and energetics analyses of swing-through gait; …

A haptic control system for functional electrical stimulation of paraplegic legs
Functional electrical stimulation (FES) is a means by which paraplegic men and women can use their natural legs for walking. In FES the impaired muscles are stimulated with electricity in a proper cycle to cause the legs to move in a walking pattern. It can be greatly beneficial for paraplegics …

Aging with Stroke: Using Functional Electrical Stimulation as a Neuromodulatory Intervention Supplement
… responses that are necessary to prevent falls. Functional Electrical Stimulation (FES) is a neuromodulatory adjunct that can improve muscular activation and cortical engagement, but its translation into scalable, home- or community-based paradigms remains limited. Objective: This dissertation …

Feedback control of cycling in spinal cord injury using functional electrical stimulation
… assisted weight lifting exercises by quadriceps stimulation has been studied in this context.

Development of Brain Computer Interface (BCI) system for integration with Functional Electrical Stimulation (FES) application
… Interface (BCI) system for integration with Functional Electrical Stimulation (FES) application. Here, the study using Electroencephalography (EEG) system for beta wave. PowerLab 8/35 and Dual Bio Amp as the detector signal the brain that will be used in this study. While, for analyze the …

Acute metabolic response to functional electrical stimulation cycling in people with MS with severe mobility impairments
… the acute metabolic demand associated with functional electrical stimulation (FES) cycling. Eleven participants with MS that required assistance for ambulation completed a session of either FES cycling or passive leg cycling. Oxygen consumption (VO2), heart rate (HR), and work rate (WR) were …

Development and assessment of methods for arm-cranking exercise assisted by functional electrical stimulation (FES) in tetraplegia
In this pilot study, a new avenue for exercise in tetraplegia, involving FES applied to upper limb muscles, is suggested. The main motivation for developing methods for FES-assisted arm-cranking exercise is to provide an exercise modality specifically designed for tetraplegia that might address …

Approaches to functional electrical stimulation induced cycling and application for the child with a spinal cord injury
… and incorporated into a PDA-based multi-functional FES system. Through both simulation and tricycle-based experiments, all three approaches have been shown to provide practical stimulation activation timing. The second research focus concerns the development of two FES-cycling systems …

The effect of functional electrical stimulation on abdominal muscle strength and gross motor function in children with cerebral palsy a randomised control trial
Includes abstract. Includes bibliographical references.

Interaction of voluntary activity and functional electrical stimulation in the upper extremity as a method for short-term alteration of corticospinal excitability and force control
… is a well-established method for rehabilitating functional movement. However, many stroke survivors are not able to participate in RMT for the necessary duration to produce results due to rapid muscle fatigue or inability to perform the desired movement at all. Often, functional electrical …

Functional electrical stimulation (FES) leg cycling exercise in paraplegia: a pilot study for the definition and assessment of exercise testing protocols and efficacy of exercise
… the effect on cycling performance of changes in stimulation parameters, and which might therefore be used to optimise them, were also investigated. Thus, a second aim of this work was to determine whether oxygen uptake and a new measure of stimulation cost (i.e. the total rate of stimulation …

The effect of functional electrical stimulation of the abdominal muscles on motor performance and activity of the trunk in patients with stroke: A pilot study
… have been found following the application of Functional Electrical Stimulation (FES) in the lower limbs in patients with stroke (1,2). Theoretically, FES could confer the same benefits if utilised on the trunk to activate the abdominal muscles. However, this is not well researched. Thus, the …

Restoration of hand and arm function to people with tetraplegia as a result of damage to the spinal cord in the neck through the use of functional electrical stimulation (FES).
Functional Electrical Stimulation (FES) therapy is a widely used rehabilitation technique to improve the hand functions of people with spinal cord injuries (SCI) and stroke. Two of the upper limb FES devices – the NeuroControl® Freehand System and the NESS H200 have received FDA approval and have …
