Increased muscle tone and exaggerated tendon reflexes characterize most of the individuals after a spinal cord injury (SCI). We estimated seven parameters from the pendulum test and used them to compare with the Ashworth modified scale of spasticity grades in three populations (retrospective study) to assess their spasticity. Three ASIA B SCI patients who exercised on a stationary FES bicycle formed group F, six ASIA B SCI patients who received only conventional therapy were in the group C, and six healthy individuals constituted the group H. The parameters from the pendulum test were used to form a single measure, termed the PT score, for each subject. The pendulum test parameters show differences between the F and C groups, but not between the F and H groups, however, statistical significance was limited due to the small study size. Results show a small deviation from the mean for all parameters in the F group and substantial deviations from the mean for the parameters in the C group. PT scores show significant differences between the F and C groups and the C and H groups and no differences between the F and C groups. The correlation between the PT score and Ashworth score was 0.88.
脊髓损伤（SCI）后大多数个体的肌肉张力增加和腱反射亢进。我们从钟摆试验中估计了七个参数，并将其与痉挛程度的改良 Ashworth 量表等级进行比较，以评估他们的痉挛情况。三组人群（回顾性研究）：在固定的 FES 自行车上运动的 3 名 ASIA B SCI 患者为 F 组，仅接受常规治疗的 6 名 ASIA B SCI 患者为 C 组，6 名健康个体为 H 组。使用钟摆试验的参数为每个受试者形成一个单一的度量，称为 PT 评分。钟摆试验参数显示 F 组和 C 组之间存在差异，但 F 组和 H 组之间没有差异，但由于研究规模较小，统计意义有限。结果表明，F 组的所有参数都偏离平均值很小，而 C 组的参数则有很大的偏差。F 组和 C 组之间以及 C 组和 H 组之间的 PT 评分存在显著差异，而 F 组和 C 组之间没有差异。PT 评分与 Ashworth 评分之间的相关性为 0.88。
