Filter by:The study will investigate the feasibility of using functional electrical stimulation (FES) of the calf muscles of paraplegic subjects to assist in posture stabilisation during standing. We aim to achieve postural stability by combining controlled FES of the lower-limb muscles with the voluntary motor control skills of the intact upper body.
Surface electrical stimulation has for many years been widely used to retrain paralysed muscle and achieve the functions of standing and stepping. Recently a number of centres have used electrical stimulation of the leg muscles to achieve cycling. During cycling the quadriceps and hamstring muscles (thigh muscles) (and sometimes also the gluteal (buttocks) muscles) are stimulated to obtain a cycling motion. Stimulation is applied using adhesive electrodes placed on the surface of the skin. This form of exercise is known as FES-cycling (FES = Functional Electrical Stimulation). We have recently carried out a pilot study which investigated the feasibility of lower-limb cycling using electrical stimulation. Cycling is accomplished using a standard recumbent tricycle, which is adapted for the purpose of FES cycling. Three people with a complete spinal cord lesion at level T7-T10 took part in the pilot study. The subjects are now able to cycle continuously and reliably on a tricycle mounted on a cycle trainer for periods of up to 1 hour. The subjects are also able to cycle outside for distances of up to 3 km. The purpose of the new study is threefold: (i) We wish to develop the equipment and methods for recreational cycling to the stage of a pre-commercial design specification; (ii) The subjects recruited for the project will carry out a progressive, high-intensity cycle-training programme. In Glasgow, 5 paraplegic subjects shall complete the training programme, which will be based at their homes. This will allow us to fully assess the feasibility of recreational FES-cycling, by measuring the power which can be sustained during long periods of cycling, and to measure the impact of the training regime on their quality of life; (iii) We will determine whether the training regime leads to significant improvements in cardiopulmonary fitness, and therefore lower risk of heart disease, and to reductions in the likelihood of the development of pressure sores and fractures. We hope that this type of exercise will lead to general improvements in the fitness of people who might use the system in future.
People with high spinal lesions are at risk of respiratory complications because they have partial or complete paralysis of breathing muscles. Previous work has shown that tetraplegic lung volumes can be increased by using abdominal FES during expiration. The technique is attractive because it is non-invasive, painless in tetraplegia and completely reversible. It may provide a treatment for augmenting the patient’s breathing both in the acute presentation of spinal injury (when half of cervical injuries require ventilation) and in long term management of tetraplegia and high paraplegia. We propose a pilot study in a small group of subjects to see if the technique is feasible from both a clinical and engineering viewpoint. The aims of the study are: 1)To examine the effects of abdominal FES on lung mechanics and gas exchange in tetraplegic subjects. 2)To optimise the stimulation pattern and intensity via electronic stimulators and to design a trigger to allow the FES to follow the subject’s own breathing cycle automatically.
The purpose of this study is to evaluate whether an aerobic and resistance training program or a functional electrical stimulation-assisted Walking program is more effective for reducing health complications related to spinal cord injury, for example, the occurrence of bladder infections, pressure sores and/or frequency of spasms. It is hypothesized that the functional electrical stimulation-assisted walking will have a greater impact on secondary complications than the aerobic and resistance training program.
