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
A custom FES-cycling ergometer equipped with an electric motor and an integrated feedback system for accurate control of exercise workrate and cadence has been employed in this study. This experimental setup allowed the imposition of arbitrary workrate profiles with high precision and provided the …

Efficacy of Hammerstein models in capturing the dynamics of isometric muscle stimulated at various frequencies
Functional electrical stimulation (FES) can be employed more effectively as a rehabilitation intervention if neuroprosthetic controllers contain muscle models appropriate to the behavioral regimes of interest. The goal of this thesis is to investigate the performance of one such model, the …

An investigation of position and force during gait-mimicking finger motions
… Currently, primitive forms of feed-forward functional electrical stimulation (FES) and special orthotics are available for persons with paraplegia. However, these forms of FES do not allow the individual to actually control their movements on a real-time basis, nor do they offer the ability …

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 …

Development of a wireless current controlled stimulator for individuals with spinal cord injury
… on the physical status and condition. The use of electrical signals to restore the function of paralyzed muscles is called functional electrical stimulation (FES). FES is a promising way to restore mobility to SCI by applying low level electrical current to the paralyzed muscles so as to enhance …
