RESUMO:

TThe reduction of the dopamine neurotransmitter in Parkinson's disease (PD) results in electrophysiological changes in the activity of neurons involved with cortico-striatal circuits and with motor and non-motor symptoms. Action Observation (AO) and Motor Imagery (MI) seem to share the same internal representation of behavior, which may enhance learning and activation of motor neural circuits in PD. Thus, the aim of this study was to verify the effects AO and MI of gait, preceded by physical practice, on gait kinematic parameters, mobility and spectral power of alpha and beta rhythms of the frontal and fronto-central bilateral cortex. We conducted a randomized controlled trial with 39 individuals with PD, who were divided into experimental group (EG = 21) and control group (CG = 18). The EG received 12 sessions of AO + MI + physical gait practice. The CG observed educational videos and performed physical practice of gait during the same period. Subjects were evaluated and reassessed 1 day after the last training session for electroencephalographic activity (data collected with a 16-sensor Emotiv Epoc wireless headset); gait kinematics (data collected with Qualisys Motion Capture Systems®) and mobility (data collected with conventional and dual-task Timed Up and Go Test). Two follow-ups were performed (7 and 30 days after the last training session) analyzing gait and mobility kinematic data. The results of this study revealed that locomotor training based on the combination of AO, MI and physical practice is more effective than physical practice in reducing maximum hip flexion during gait swing phase, increasing hip range of motion, increasing knee extension in the initial contact phase, increasing speed and mobility. It was also observed that the spectral power of the alpha rhythms for the F4 channel increased significantly for the EG during gait execution, as well as the reduction of the beta rhythm power for the FC6 channel for the same group also during gait execution. These data indicate that the EG may have shown motor improvement strongly correlated with lower levels of attentional demand during gait execution after training.
