Effect of Motor-Cognitive (Dual Task) Rehabilitation Program on Gait Biomechanics in Parkinson’s Disease: Case Study

In some pathologies with impaired control gait, the dual task execution even worse these gait alterations, as in Parkinson’s Disease (PD) occurs. The aim of this paper is to present the effects of a rehabilitation program that integrates dual tasks in gait rehabilitation and prepare patients to move functionally in complex environments in a person with PD. 3D photogrammetry system and two force platform were used for the registering of kinematic and kinetic parameters, respectively. The main variables that have improved after the proposed program are: speed gait (54.87 %), step length (52.01 %), stride length (43.48 %), double support time (37.36 %), flexo-extension hip range of motion (36.08 %) and vertical reaction force at the heel contact moment (23 %). The inclusion of complex environments representative of daily life activities in gait rehabilitation is useful for improving the performance of walking when parkinsonian gait impairment is suffered.
