dc.description.abstract
OBJECTIVE: The 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. METHODS: Twenty 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. RESULTS: 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). 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). CONCLUSIONS: Patients 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.
