To investigate the relationship between the distribution and severity of hypertonicity and spasticity on walking speed in people with neurological injuries.
MATERIAL/METHODS: This cross-sectional observation cohort study used the Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) to assess hypertonicity and spasticity of the gastrocnemius, soleus, hamstrings and quadriceps. Participants were classified as having a distal (gastrocnemius and/or soleus), proximal (hamstrings and/or quadriceps) or mixed distribution of hypertonicity or spasticity. The 10-m walk test was used to quantify walking speed.
Seventy-five individuals with an adult-onset neurological condition participated. Those with a mixed distribution of hypertonicity or spasticity walked more slowly than those with a distal distribution. This finding was statistically significant when examining spasticity (0.54 vs 1.05 m/sec, = 0.005), not hypertonicity (0.73 vs 1.05 m/sec, = 0.162). The higher the severity score of hypertonicity or spasticity, the lower the walking speed. This finding was statistically significant when examining hypertonicity ( = -0.502, < 0.001), but not spasticity ( = -0.171, = 0.143).
The severity of hypertonicity demonstrated a relationship with walking speed, whereas the severity of spasticity did not. Results for the MAS and MTS are not interchangeable.
探讨神经损伤患者中张力亢进和痉挛的分布及严重程度与步行速度之间的关系。
材料/方法：这项横断面观察队列研究使用改良Ashworth量表（MAS）和改良Tardieu量表（MTS）评估腓肠肌、比目鱼肌、腘绳肌和股四头肌的张力亢进和痉挛情况。参与者被分类为具有张力亢进或痉挛的远端（腓肠肌和/或比目鱼肌）、近端（腘绳肌和/或股四头肌）或混合分布。采用10米步行测试来量化步行速度。
75名成年起病的神经疾病患者参与了研究。张力亢进或痉挛呈混合分布的患者比远端分布的患者步行速度更慢。在检查痉挛时，这一发现具有统计学意义（0.54对1.05米/秒，P = 0.005），而在检查张力亢进时则无统计学意义（0.73对1.05米/秒，P = 0.162）。张力亢进或痉挛的严重程度评分越高，步行速度越低。在检查张力亢进时，这一发现具有统计学意义（P = -0.502，P < 0.001），但在检查痉挛时则无统计学意义（P = -0.171，P = 0.143）。
张力亢进的严重程度与步行速度有关，而痉挛的严重程度则无关。MAS和MTS的结果不可互换。
