简要总结
Deficits in automatic motor control, characteristic of Parkinson's disease (PD), contribute to progressive impairment in gait performance. The use of declarative memory cues in order to promote the engagement of attention and activation of the next movement in gait may minimize the consequences of lack of automatic control. The purpose of this study is to verify the long-term efficiency of a new strategy based on declarative memory cue to improve the gait performance and independence in daily life activities (DLA) in patients with PD.
详细描述
Background: Deficits in automatic motor control, characteristic of Parkinson's disease (PD), contribute to progressive impairment in gait performance. The use of declarative memory cues in order to promote the engagement of attention and activation of the next movement in gait may minimize the consequences of lack of automatic control.
Objectives: To verify the long-term efficiency of a new strategy based on declarative memory cue to improve the gait performance and independence in daily life activities (DLA) in patients with PD.
Design: Parallel prospective, single blind, randomized clinical trial. Setting: Brazilian Parkinson Association. Participants: Forty-four patients with PD in stages 2-3 of disease evolution according to Hoehn and Yahr Classification Interventions: The experimental training (ET) consisted of eight gait training sessions, twice a week, using the declarative memory cues strategy (DMCS). The control training (CT) consisted of a similar gait training without DMCS.
Primary outcome measure: Gait performance in terms of speed and stride length. Secondary outcome measure: Independence in DLA according to Section II of the Unified Parkinson's Disease Rating Scale.
Randomization: Participants were randomized into a control group (CG), which performed the CT, and an experimental group (EG), which performed the ET, through blinded drawing of names.

结局指标
主要结局
gait speed
时间窗: up to 3 months
The first primary outcome was the gait speed (m/s). Patients were asked to walk in a straight trajectory of 20 meter following the sole instruction "upon the go signal, walk as fast as possible at the line and stop". The speed was calculated based on the time to walk 20 meters timed using a digital chronometer.
stride length on gait
时间窗: up to 3 months
The second primary outcome was the stride length (cm) on gait. Patients were asked to walk in a straight trajectory of 20 meter following the sole instruction "upon the go signal, walk as fast as possible at the line and stop". The number of steps was measured using a pedometer.
次要结局
- Independence in activities of daily living (ADL)(up to 3 months)
