Individuals with spinal cord injury (SCI) are more than twice as likely to develop and die from cardio-metabolic diseases as compared to able-bodied. This increased risk is thought to be in part due to accelerated muscle atrophy and reduced blood flow through sublesional arteries. Thus, strategies to recondition paralyzed skeletal muscles may help reduce cardio-metabolic disease risk. The purpose of this case report was to examine the impact of a novel, resistance-guided, high intensity interval training functional electrical stimulation (RG-HIIT-FES) cycling program on cardio-metabolic health in people with chronic SCI.
One adult female with chronic T10 SCI.
A novel RG-HIIT-FES cycling program three times per week for 10 weeks. Measures of body composition and cardio-metabolic health (vascular endothelial function of the brachial artery via flow-mediated dilation) and HbA1c blood values were performed at baseline and following completion of the RG-HIIT-FES program.
Total body lean mass and legs lean mass increased 2.8% and 5.3% respectively while vastus lateralis thickness increased by 59.5%. Reactive hyperemia and flow mediated dilation change in brachial artery diameter increased by 11.1% and 147.7% following the program, respectively. HbA1c level changed minimally (5 to 4.9%).
This case report suggests that RG-HIIT-FES cycling was an effective strategy to improve lean mass, and systemic vascular endothelial health in an individual with chronic SCI.
与身体健全者相比，脊髓损伤（SCI）患者患心血管代谢疾病并死于该病的可能性要高出两倍多。这种风险增加被认为部分归因于肌肉萎缩加速和损伤平面以下动脉血流量减少。因此，修复瘫痪骨骼肌的策略可能有助于降低心血管代谢疾病风险。本病例报告的目的是研究一种新型的、阻力引导的、高强度间歇训练功能性电刺激（RG-HIIT-FES）骑行计划对慢性SCI患者心血管代谢健康的影响。
一名成年女性，患有慢性T10脊髓损伤。
一种新型的RG-HIIT-FES骑行计划，每周进行三次，共10周。在基线时以及RG-HIIT-FES计划完成后，对身体成分、心血管代谢健康（通过血流介导的扩张测量肱动脉血管内皮功能）和糖化血红蛋白（HbA1c）血液值进行测量。
全身瘦体重和腿部瘦体重分别增加了2.8%和5.3%，而股外侧肌厚度增加了59.5%。该计划实施后，肱动脉反应性充血和血流介导的扩张导致的直径变化分别增加了11.1%和147.7%。HbA1c水平变化极小（从5%降至4.9%）。
本病例报告表明，RG-HIIT-FES骑行是改善慢性SCI患者瘦体重和全身血管内皮健康的有效策略。
