简要总结
Spinal cord injury (SCI) is a devastating, life-altering injury; requiring tremendous changes in an individual's lifestyle. Cycling, provides an ideal way for individuals with SCI to exercise and address the long-term consequences of SCI by targeting the lower extremity muscles. Cycling with the addition of functional electrical stimulation (FES) allows persons with paralysis to exercise their paretic or paralysed leg muscles. The Queen Elizabeth National Spinal Injury Unit (QENSIU) in Glasgow offers FES cycling for people with spinal cord injuries, which combines functional electrical stimulation (FES) with a motorised ergometer that allows repetitive cycling activity. It stimulates muscles with electrodes attached to the skin, producing muscle contractions and patterned activity. So far no previous randomised control trials on FES cycling in the acute SCI population have reported changes in ability to undertake activities of daily living or the trunk balance.
详细描述
Up to 12 participants admitted to the QENSIU will be recruited to the study. They will be randomised to the intervention (n=8) or control group (n=4). The intervention group will receive 6 weeks FES cycling training in addition to usual care; the control group will receive usual care only. Outcome measures: Spinal Cord Injury Functional Ambulation Inventory, The Spinal Cord Independence Measure, ASIA Impairment Scale, Handheld dynamometry, 10-Metre Walking Test, Timed Up and Go Test, Trunk Impairment Scale, Modified Ashworth scale, Modified Tardieu Scale, the Patients Global Impression of Change.

研究组 & 干预措施
Intervention
FES cycle training will be performed on the RT300 FES cycle ideally 3 times per week for 6 weeks, each session lasting up to 90 minutes. Electrical stimulation will be delivered through up to 12 independent channels each delivering up to 140 mA current on the following muscles (both on the right and left leg): quadriceps, femoral biceps and gluteus, gastrocnemius and tibialis anterior. Abdominal and back extensor muscles may also be stimulated if the participant presents with neurological trunk weakness (SCI above T6). The FES unit will stimulate the muscles that extend the hip (gluteals), flex the knee (hamstrings) and extend the knee (quadriceps) in the correct order to bring about a cycling motion. The feet and lower legs of the participants will be strapped into the pedals and the wheelchair will be coupled in a rigid manner with the training device.
干预措施: FES Cycling (Device)
Control
Participants in the control group will receive usual care, consistent with standard NHS care in this population. Usual physiotherapy care is provided, up to 2 times per day, 4 to 5 days per week, each lasting approximately 90 minutes. Physiotherapists provide one to one function-oriented physiotherapy session to improve balance, muscle strength and transfer skills.
结局指标
主要结局
Change in Spinal Cord Injury Functional Ambulation Inventory (SCI- FAI)
时间窗: baseline, 6 weeks, 12 weeks
It consists of three components: gait parameter, assistive device use and walking ability. The gait parameter component is scored out of 20, 10 points for each of the right and left sides. The assistive device component is scored out of 14 (7 points for each side), and assesses upper and lower extremities in addition to the left and right limbs. Scores within each component are summed. Component scores range from 0 to 20 in the gait parameter component, 0 to 14 in the assistive device component, and 0 to 5 in the walking mobility component. The SCI-FAI is a reliable, valid and sensitive measure of walking ability in individuals with spinal cord injury.
