Introduction:
Hemiplegia is a complication, results from upper motor neuron lesions and is usually associated with spasticity and movement disorders. To control spasticity and accomplish functional activities, several approaches have been presented such as Neurodevelopment treatment (NDT), according to Bobath^,s assumptions. Although lower limb spastic hemiplegia is common and its management is time-consuming, in this study we were intended to examine the effectiveness of this therapeutic approach on spasticity management and quality of lower limb movement patterns.                                                                               
Methods:
Fifteen hemiplegic patients (age range, 44-75) participated in this study. Baseline assessments before and after the treatment included: spasticity measurement of plantar flexor muscles of ankle according to the Original Ashworth Scale (OAS), measurement of active and passive range of motion of ankle dorsiflexion and defining the quality of lower limb movement patterns according to "Standing test" of  Bobath^,s  approach.                                   
Results:
Following intervention (20 sessions), there was a significant decrease in spasticity and a significant increase in an active and passive range of motion and quality of movement patterns.
Conclusion:
According to the obtained results, by modification of excitation – inhibition in CNS and transmitting it to the peripheral region (muscles), Bobath’s approach can reduce the spasticity of plantar flexor muscles, subsequently, the dorsiflexion range of motion increases.  Indeed, this therapeutic approach increases coordination in movement patterns and improves quality of movement patterns by retraining balance in various positions. Results of this study may be used extensively in management of patients with upper motor neuron lesion referred to rehabilitation centers.
