Análise cinemática da marcha associada à dupla tarefa em pacientes atáxicos: estudo piloto

Abstract

Objective: to evaluate the linear kinematics of gait associated with dual task in ataxic patients. Methodology: Pilot study that evaluated 3 individuals, aged between 34 and 43 years. First, the simple tasks were performed: simple gait, cognitive task, motor task and cognitive-motor task. Afterwards, they were performed as dual tasks, where gait was associated with cognitive, motor and cognitive-motor activities. For gait assessment, a three-dimensional gait trajectory capture system was used and the variables evaluated were speed, cadence, step size, step width, step time, stride size, stride time and double support. Results: the individuals showed differences within most variables comparing simple gait with dual tasks, worsening the gait pattern when performing the combined tasks. In dual tasks, the individuals were slower, having their speed, cadence and stride length reduced, generating an increase in stride time. There was an increase in double support time in most dual tasks compared to isolated gait. Conclusion: There were changes in the kinematic of gait in dual task in patients with ataxia, worsening locomotor pattern, and with greater influence of the cognitive-motor task when compared to the cognitive and motor tasks.
