目的是研究电刺激小腿肌肉对摆动腿运动效果的影响。这项研究是在一组不完全脊髓损伤的患者中进行的，这些患者都是在静止状态下和拐杖辅助行走时进行的。在对踝跖屈肌施加刺激之前，膝伸肌被灭活。在每个周期中，在踝跖屈肌刺激之后，开始腓神经刺激，触发屈曲反射。从生物力学的角度来看，踝跖屈肌的功能性电刺激（FES）可增加下肢的离地间隙。此外，FES辅助的脚跟抬起导致伸肌张力的消除，从而缩短了挥杆时间。
The aim is to study the influence of electrically stimulated calf muscles on the effectiveness of the swinging leg movement. The study is carried out with a group of patients with incomplete spinal cord injuries both under stationary conditions and during crutch-assisted walking. Before stimulation is applied to the ankle plantar flexors,the knee extensors are inactivated. In each cycle, after ankle plantar flexor stimulation, peroneal stimulation is started, triggering the flexion reflex. From a biomechanical point of view, functional electrical stimulation (FES) of the ankle plantar flexors results in increased ground clearance of the lower extremity. Additionally, the FES-assisted lifting of the heel results in the elimination of extensor tone and thus shortens the swing time.
