Abstract :
Spasticity is one of the common complications in upper motor neuron lesions and without
appropriate treatment it causes disturbances in movement pattern. Assessments of patients are effective in
patient`s management. Modified Ashworth scale (MAS) is one of the criteria in qualitative assessment of
spasticity, and there are lots of controversies about its validity. The purpose of this study is to compare MAS
with electrophysiological indices of spasticity. The spasticity of upper limb muscles in patients with
hemiplegic cerebral palsy are measured and recorded by MAS. Then electrophysiological indices of
Hoffmann reflex (H reflex) and ratio of maximum range of action potential of combined movement of flexor
carpi radialis (FCR) for upper limb and soleus for lower limb were estimated. Data of 11 patients with age
range 4 to 6 were analyzed. There is no significant correlation between degree of spasticity and
electrophysiological indices.
