To evaluate the effect of neuromuscular electrical stimulation on spasticity in patients with spinal cord injury.
The study included eleven subjects with spinal cord injuries (C4 to T5). The modified Ashworth scale and pendulum test, which is accomplished through the Pendular Test Device - PTD (equipment which has a quartz crystal transducer accelerometer and optic fiber flexible electrogoniometer measuring the tensions and angular displacements). Patients underwent neuromuscular electrical stimulation (NMES) to the quadriceps muscle from fibular nerve, and the tests were administered before and after therapy.
The data show a decrease in spasticity after NMES, with features such as increased variation between maximum and minimum peaks, i.e. increased amplitude of the curves. Furthermore, data from the subjective scale, and modified Ashworth scale after neuromuscular electrical stimulation also showed a reduction in the values of spasticity.
The data suggest that NMES is effective in reducing spasticity immediately after completion. Level of Evidence II, Therapeutic Studies-Investigating the Results of Treatment .
评估神经肌肉电刺激对脊髓损伤患者痉挛的影响。
该研究纳入了11名脊髓损伤（C4至T5）患者。采用改良Ashworth量表和摆锤试验，摆锤试验通过摆锤测试装置（PTD）完成（该设备具有石英晶体换能器加速度计和光纤柔性电子测角仪，用于测量张力和角位移）。患者接受腓总神经对股四头肌的神经肌肉电刺激（NMES），并在治疗前后进行测试。
数据显示NMES后痉挛减轻，特征为最大和最小峰值之间的变化增加，即曲线幅度增加。此外，主观量表数据以及神经肌肉电刺激后的改良Ashworth量表也显示痉挛值降低。
数据表明NMES在完成后可立即有效减轻痉挛。证据等级II，治疗研究-调查治疗结果。
