Detailed Description
INTRODUCTION:
Individuals with spinal cord injuries (SCI) experience balance impairments and limitations in walking. Newer research demonstrates that even after several years individuals with incomplete SCIs can make significant gains in function when they are engaged in targeted physical activity. Previous studies using functional electrical stimulation and locomotion training report reduced spasticity and reflex control, increased electromyography activity during stepping, and increased thigh muscles mass. However, these methods and instruments are bulky, expensive, need technical maintenance, and must be used in a clinical setting. A novel rehabilitation bicycle that uses simultaneous stimulation of plantar mechanoreceptors and hip joint proprioceptors was developed in the department of Biomedical Engineering of University of Manitoba. An advantage of this device is that patients can use it at home and with minimal assistance. Five patients completed initial pilot testing and exhibited an overall improvement on the Berg Balance Scale. Presently, the effect of rehabilitation bike training on the plasticity of the spinal and corticospinal neuronal circuitry and consequently its effects on the functional walking capacity are unclear.
OBJECTIVES:
The purpose of the present study is to evaluate the effect of the rehabilitation bike on corticospinal and spinal plasticity, and functional walking and balance in incomplete SCI individuals.
METHODS:
Ten individuals with chronic incomplete SCI will participate in this study. The protocol will include 30 minute training sessions, three times/week, for 8 weeks. The study design will be a before-after clinical trial with two baseline assessments prior to training. Post-training evaluation after two weeks will be done and there will be a post-training follow-up assessment after two weeks.
Evaluations of functional recovery and independence include: Six -Minute and Ten-Meter Walk Tests, Walking index for spinal cord injury(WISCI II). The Berg Balance Scale(BBS) will be conducted to assess balance. Results will be compared before and after training. H-reflex and motor evoked potential (using transcranial magnetic stimulation ,TMS) will also be measured before and after cycling training to assess the plasticity at the level of the spine and in the corticospinal pathways respectively.
ANTICIPATED RESULTS:
Compared to locomotion training with treadmills and robotic devices, using the rehabilitation bike is affordable and patients are able to use it independently at home, without the help of a physical therapist or a caregiver. Results of this study will clarify the possible positive effect of training with the rehabilitation bike on the corticospinal reorganization as well as training effects on the functional recovery of balance and walking. If the findings from the present study are consistent with the initial pilot data, then it will provide incomplete SCI patients and their therapists with a new option for rehabilitation that is feasible and cost-effective. Considering the relatively high incidence of SCI in Manitoba, the findings from this study will directly improve quality of life for Manitobans and Canadians living with spinal cord injuries.
