简要总结
The aim of the study is to evaluate the effect of normal gait imagery and gait on a line imagery on lower limb muscle activity and lower body kinematics in stroke survivors.
详细描述
Gait imagery is a cognitive process involving the mental simulation of a gait that is not actually performed. According to current studies, gait imagery has very similar neural activity to that observed in real gait. This activity can be observed not only at the central level, but also at the end effector - the muscle - using surface electromyography. Across studies, muscle activity and kinematics are evaluated in particular when imagining analytical movements of the upper or lower limbs, but complex and posturally more demanding movements (in our case, gait and its modification - gait on a line) are studied to a lesser extent. Independent walking and the ability to adapt it to the terrain is important in rehabilitation therapy for patients with limited mobility. These individuals include, among others, a stroke survivors. The aim of the study is therefore to evaluate the effect of normal gait imagery and gait on a line imagery on lower limb muscle activity and lower body kinematics in these individuals.

研究组 & 干预措施
Intervention
All individuals will be instructed to realize normal gait imagery (NGI) and gait on the line imagery (GLI) modalities in a single experimental session. The order of imagining these two gait modalities was randomized and both modalities consisted of these tasks: rest (non-imagery task), NGI/GLI before and after the real execution of normal gait/tandem gait on the line. The order of the tasks was not randomized.
Individuals are also asked about the ease/difficulty of imagining both NGI/GLI before and after the real execution of gait tasks using a five-point scale.
Each task is measured once for 30 s with respect to sustained attention and possible onset of fatigue.
干预措施: gait imagery (Behavioral)
结局指标
主要结局
Objective measurement of muscle activity
时间窗: Day 1
Muscle activity \[V\] will be measured by surface electromyography during all tasks (rest and gait imagery before/after real gait execution) across both gait imagery modalities (normal gait imagery and gait on the line imagery).
Objective measurement of lower body kinematics 1
时间窗: Day 1
Lower body kinematics will be measured by gyroscope \[deg/s\] during all tasks (rest and gait imagery before/after real gait execution) across both gait imagery modalities (normal gait imagery and gait on the line imagery).
Objective measurement of lower body kinematics 2
时间窗: Day 1
Lower body kinematics will also be measured by accelerometer \[g\] during all tasks (rest and gait imagery before/after real gait execution) across both gait imagery modalities (normal gait imagery and gait on the line imagery).
