Dataset Information

Full body mobile brain-body imaging data during unconstrained locomotion on stairs, ramps, and level ground.

ABSTRACT: Human locomotion is a complex process that requires the integration of central and peripheral nervous signalling. Understanding the brain's involvement in locomotion is challenging and is traditionally investigated during locomotor imagination or observation. However, stationary imaging methods lack the ability to infer information about the peripheral and central signalling during actual task execution. In this report, we present a dataset containing simultaneously recorded electroencephalography (EEG), lower-limb electromyography (EMG), and full body motion capture recorded from ten able-bodied individuals. The subjects completed an average of twenty trials on an experimental gait course containing level-ground, ramps, and stairs. We recorded 60-channel EEG from the scalp and 4-channel EOG from the face and temples. Surface EMG was recorded from six muscle sites bilaterally on the thigh and shank. The motion capture system consisted of seventeen wireless IMUs, allowing for unconstrained ambulation in the experimental space. In this report, we present the rationale for collecting these data, a detailed explanation of the experimental setup, and a brief validation of the data quality.

Project description:ObjectiveThe aim of this study was to compare gaze behaviour during stair and ramp walking between patients with chronic peripheral vestibular hypofunction and healthy human subjects.MethodsTwenty four (24) patients with chronic peripheral vestibular hypofunction (14 unilateral and 10 bilateral) and 24 healthy subjects performed stair and ramp up and down walks at self-selected speed. The walks were repeated five times. A mobile eye tracker was used to record gaze behaviour (defined as time directed to pre-defined areas) and an insole measurement device assessed gait (speed, step time, step length). During each walk gaze behaviour relative to i) detection of first transition area "First TA", ii) detection of steps of the mid-staircase area and the handrail "Structure", iii) detection of second transition area "Second TA", and iv) looking elsewhere "Elsewhere" was assessed and expressed as a percentage of the walk duration. For all variables, a one-way ANOVA followed by contrast tests was conducted.ResultsPatients looked significantly longer at the "Structure" (p<0.001) and "Elsewhere" (p<0.001) while walking upstairs compared to walking downstairs (p<0.013). Patients looked significantly longer at the "Structure" (p<0.001) and "Elsewhere" (p<0.001) while walking upstairs compared to walking downstairs (p<0.013). No differences between groups were observed for the transition areas with exception of stair ascending. Patients were also slower going downstairs (p = 0.002) and presented with an increased step time (p = 0.003). Patients were walking faster up the ramp (p = 0.014) with longer step length (p = 0.008) compared to walking down the ramp (p = 0.050) with shorter step length (p = 0.024).ConclusionsPatients with chronic peripheral vestibular hypofunction differed in time directed to pre-defined areas during stair and ramp walking and looked longer at stair and ramp areas of interest during walking compared to healthy subjects. Patients did not differ in time directed to pre-defined areas during the stair-floor transition area while going downstairs, an area where accidents may frequently occur.
