ABSTRACT

The natural history of Duchenne muscular dystrophy is the gait impairment characterized by progressive wasting of proximal muscles, increase in the endeavor to walking and final dependency of wheelchair towards the ten years of age. Objective: To analyze the gait kinematic in patients with Duchenne muscular dystrophy in stage 2, 3 and 4 of Vignos Scale. Method: Six patients between 3 to 11 years of age were included. Three-dimensional gait analysis included temporary-spatial parameters, kinematic and ground reaction forces. Results: The average cadence was 123.5 ± 6.36 steps per minute; velocity mean was 0.69 ± 0.08 m/s. The kinematic of hip, knee and ankle showed differences in the peaks of flexion and extension in patients over ten years and these were independent of Vignos stage. Ground reaction forces exhibited decrease in the magnitude of vertical force in all patients. Conclusion: The phase 4 of Vignos functional scale was the most critical stage of gait in patients with Duchenne muscular dystrophy because the changes in kinematics are determinants in the illness progression.
