PURPOSE This study investigated whether muscle fatigue during functional electrical stimulation (FES)-induced cycling was associated with changes occurring in evoked electromyographic signals (eEMG, M-waves) in individuals with spinal cord injury. We also explored the effects of recovery intervals between exercise sessions on the relationship between eEMG(More)
An isokinetic functional electrical stimulation leg cycle ergometer (iFES-LCE) was developed for individuals with spinal cord injury (SCI). The iFES-LCE was designed to allow cycle training over a broad range of pedalling cadences (5-60 rev/min) to promote both muscular strength and cardiorespiratory fitness. A commercially available motorized cycle(More)
Objectives.  To investigate the nature of the force-velocity relationship on muscle forces and power outputs during functional electrical stimulation (FES)-evoked cycling at different pedaling cadences. Materials and Methods.  Ten patients with T4-T9 spinal cord injuries (ASIA A) performed FES-evoked cycling at 50 rev/min using a motorized isokinetic(More)
This study investigated the activation dynamics of electrical stimulation-evoked muscle contractions performed by individuals with spinal cord injury (SCI). The purpose was to determine whether electrical stimulation (ES) firing patterns during cycling exercise should be altered in response to fatigue-induced changes in the time taken for force to rise and(More)
This is a case series study with the objective of comparing two motion sensor automated strategies to avert knee buckle during functional electrical stimulation (FES)-standing against a conventional hand-controlled (HC) FES approach. The research was conducted in a clinical exercise laboratory gymnasium at the University of Sydney, Australia. The automated(More)
OBJECTIVE To investigate the effect of shank muscle stimulation on ankle joint excursion during passive and functional electrical stimulation (FES) leg cycling. DESIGN Within-subject comparisons. SETTING Laboratory setting. PARTICIPANTS Well-trained FES cyclists (N=7) with chronic spinal cord injuries. INTERVENTIONS Two experimental sessions were(More)
This study developed a real-time system which was capable of separating voluntary EMG (VEMG) and evoked EMG (EEMG) from mixed EMG (MEMG) signals elicited by voluntary and simultaneous electrical stimulation-induced muscle contractions. A stimulus artefact suppressor developed in our laboratory was employed to remove artefacts from MEMG, before it was(More)
