Cervical spinal cord injury (SCI) leads to tetraplegia, with paralysis and loss of sensation in the upper and lower limbs. The associated sedentary lifestyle results in an increased risk of cardiovascular disease. To address this, we require the design of exercise modalities aimed specifically at tetraplegia and methods to assess their efficacy. This paper describes methods for arm-crank ergome...

We are constructing a physiologically realistic model of the muscle spindle to assist in the analysis of natural sensorimotor control and to design biomimetic systems for functional electrical stimulation (FES). Our model is composed of mathematical elements that correspond closely to the anatomical components of spindles. The resulting nonlinear model is reasonably accurate in predicting publi...

This paper presents the development of a model of indoor rowing exercise for paraplegics. Indoor rowing exercise is introduced as a hybrid exercise for restoration of function of lower extremities for paraplegics through the application of functional electrical stimulation (FES). Two stimulated muscle models, quadriceps and hamstrings, are developed for knee extension and flexion. A fuzzy logic...

A new assist mechanism, represented by a flywheel and an electrical clutch, is developed and evaluated, in simulation studies, to assist paralysed legs during functional electrical stimulation (FES)-based cycling exercise in a closed-loop control configuration. The flywheel is engaged and disengaged, by the clutch, to assist or retard the cycling when necessary. The flywheel engages with the cr...

OBJECTIVE To investigate adaptive changes in bone and muscle parameters in the paralysed limbs after detraining or reduced functional electrical stimulation (FES) induced cycling following high-volume FES-cycling in chronic spinal cord injury. SUBJECTS Five subjects with motor-sensory complete spinal cord injury (age 38.6 years, lesion duration 11.4 years) were included. Four subjects stopped...

Implanted functional electrical stimulation (FES) systems for walking are experimentally available to individuals with incomplete spinal cord injury (SCI); however, data on short-term therapeutic and functional outcomes are limited. The goal of this study was to quantify therapeutic and functional effects of an implanted FES system for walking after incomplete cervical SCI. After robotic-assist...

Individuals with Spinal Cord Injury (SCI), perform Sitting Pivot Transfer (SPT) motion around fifteen times a day using upper extremities. It can lead to upper limbs pain and often shoulder complications. In this paper, we investigate the influence of Functional Electrical Stimulation (FES) on SPT motion of a paraplegic person. First, we proposed to develop...

Prolonged immobilization results in several physiological problems. It has been demonstrated that standing exercises can ameliorate many of these problems. Standing exercises can be performed efficiently with the help of functional electrical stimulation (FES). A novel robotic mechanism which aids the unsupported standing of paraplegics, providing balancing exercise has been developed. The bala...

This case report describes a stroke patient who participated in an intensive functional electrical stimulation (FES) therapy that consisted of task-specific upper arm movements with a combination of pre-programmed electrical stimulation and manually assisted motion. The patient was a 22-year-old woman who had suffered a hemorrhagic stroke 2 years earlier. Motor function of the upper extremity w...
