INTRODUCTION: The hemiparesy after the stroke is the most common sequelae hampering the speed of execution of automatic movements, reducing the autonomy of the individual and causing disability. OBJECTIVES: To analyze the effect of spasticity in linear patterns of movement (PLM) in hemiparetic subjects. METHODS: Two groups were studied: 20 individuals with stroke (G1) and 20 healthy subjects (G2) with a mean age of 54.2 and 52.6 respectively. Were evaluated by the PLM protocol Nagasaki, muscle tone by modified Ashworth scale and range of motion by goniometry. All parameters were compared in two groups by Student t test and Spearman correlation with a significance level p < 0,05. RESULTS: The mean distance was 14.52 m and 32.16 m, and time was 23.75 s and 19.02 s for G1 and G2 respectively (p < 0.0001). Comparing the groups average amplitude and average speed step were statistically significant (p < 0.05) and cadence was not significant (p = 0.1936). When the PLM were compared with the degree of spasticity of the gastrocnemius and soleus muscles showed a negative association with distance, speed and step amplitude and positive association with time (p < 0.05). CONCLUSION: The higher the degree of spasticity of the gastrocnemius and soleus muscles, the smaller the linear parameters of the gait of individuals with hemiparesis post stroke sequelae.
