Abstract:
Objective To explore the impact of vision impairment(VI)on the gait of hemiplegic patients,assess their walking ability and fall risks,and provide a basis for developing effective rehabilitation strategies.Methods Thirty hemiplegic patients were enrolled and stratified by the severity of visual acuity impairment into three groups(unimpaired,mildly impaired,and severely impaired).The gait data of patients under uncorrected vision were collected using the Qualisys motion capture system and the Kistler three-dimensional force platform,and the balance ability of patients was assessed simultaneously.Subsequently,the gait and assessment data were statistically analyzed to compare inter-group differences.Results Compared with the visually unimpaired group,significant differences in step length,symmetry,and walking speed were observed in hemiplegic patients of the mild visual impairment group and severe visual impairment group.As VI increased,gait abnormalities became more pronounced,with a longer double-limb support phase,a longer swing phase of the affected limb,and a shorter single-limb support phase of the affected limb in the gait cycle.Compared with the visually unimpaired group,significant differences in center of pressure(COP)and COP symmetry were found between the mild visual impairment group and severe visual impairment group,with gait abnormalities intensifying.The Berg balance scale(BBS)scores showed that there was a significant difference between the visually unimpaired group and severe visual impairment group,indicating that the group with visual impairment had poorer balance ability.Conclusions VI has a significant negative impact on the gait and walking ability of hemiplegic patients.This study emphasizes the importance of focusing on the impact of VI in the rehabilitation of hemiplegic patients,with regular vision assessments and personalized interventions being conducted,which are of great significance in enhancing patients' walking quality.
