This paper presents the results of cardiovascular changes that occur during a novel rehabilitation strategy called activity based therapy (ABT). Blood volume pulse (BVP) signals were measured during functional electrical stimulation (FES)-induced cycling in adults with spinal cord injury (SCI) persons and results were compared to a passive cycling task and able-bodied controls performing normal cycling. BVP signals were compared during three conditions, a baseline pre-exercise condition, 5 minutes after exercise and after 30-minutes rest following exercise. Exercise recovery was evaluated using normalized inner products values in BVP signals. The results showed that FES-induced cycling in SCI participants resulted in a significantly greater peripheral resistance level and longer time to recover from exercise compared with passive cycling and normal cycling in able-bodied controls.
本文介绍了一种名为基于活动疗法（ABT）的新型康复策略过程中发生的心血管变化结果。在脊髓损伤（SCI）成人患者进行功能性电刺激（FES）诱导的骑行过程中测量了血容量脉搏（BVP）信号，并将结果与被动骑行任务以及进行正常骑行的健全对照者进行了比较。在三种情况下比较了BVP信号，即运动前的基线状态、运动后5分钟以及运动后30分钟休息后。使用BVP信号中的归一化内积值评估运动恢复情况。结果表明，与健全对照者的被动骑行和正常骑行相比，SCI参与者中FES诱导的骑行导致外周阻力水平显著更高，且运动恢复时间更长。
