Abstract

Background: SPASTICITY is a common and disabling complication that occurs as a result of upper motor neuron lesion and can induce movement disability unless treated. Most of the previous treatment evaluations have been based on qualitative assessments, but quantitative evaluation of SPASTICITY is also important and necessary. In this study, we tried to assess and compare the effect of BTX-A in severity of SPASTICITY based on clinical and electrophysiological assessments Materials and methods: This study was designed clinical trial before and after 15 hemiplegic patients (age ranged 44- 70 yr) with SPASTICITY of ankle plantar flexors participated in this study. Before and after intervention, SPASTICITY of the given muscles was assessed according to Original Ashworth Scale (OAS).Electrophysiologic measurements consisted of amplitude of maximum H- reflex, M response and H/M ratio of soleus muscle, that were recorded and compared before and after injection.Toxin injection was performed in gastrocnemos muscle (200 unit), soleus muscle (75 unit) and posterior tibialis muscles (50 unit).Results: Four weeks after injection significant decrease in H- reflex amplitude M response and H/M ratio was observed. Severity of SPASTICITY according to OAS also showed a significant decrease. There was a significant relationship between decrease of H- reflex amplitude and SPASTICITY decrement via OAS. There was a direct and meaningful correlation between H-reflex slope reduction and the decrease in SPASTICITY OAS.Conclusion: BTX-A can reduce the severity of SPASTICITY by pre- synaptic inhibition in neuro- muscular junction. It can also affect on muscle spindles and reduce the afferent vallies of la, thereby reduce the amplitude of H reflex and HIM ratio. These changes clinically define the decrease SPASTICITY severity quantitative and qualitative.
