An Observational Study of the Kinematic Characteristics of the Acromion-pelvic Angle during Walking in Stroke Patients
摘要
Abstract
Objective:To investigate the kinematic characteristics of acromion-pelvic angle during walking in stroke patients by comparing them with healthy subjects,and to analyze the reasons underneath from biomachan-ic perspective.Methods:A total of 45 stroke subjects(stroke group)and 9 healthy subjects(control group)were recruited from the Department of Rehabilitation Medicine,West China Hospital,Sichuan University.3D gait analysis was used to compare whether there were statistical differences between two groups in the main out-come indicators such as gait speed,stance time,peak acromion-pelvic angle during stance phase,and peak acro-mion-pelvic angle during whole gait cycle.In addition,the reasons for the statistical difference between the two groups were analyzed from the biomechanical perspective.Results:Compared with healthy adults,there were statistically significant differences in peak acromion-pelvic angle during stance phase,peak acromion-pelvic an-gle during whole gait cycle,and gait speed(all P<0.01).This study also found that the maximum value of acro-mion-pelvic angle during stance phase in stroke patients was positively correlated with peak foot angle,and neg-atively correlated with minimum thorax rotation angle,minimum ankle dorsiflexion-plantar flexion angle,and minimum value of ankle moment.The maximum acromion-pelvic angle was positively correlated with peak hip saggital moment,hip saggital power,and foot angle,and negatively correlated with minimum hip flexion and ex-tension angle,minimum ankle dorsiflexion-plantar flexion angle,and minimum ankle sagittal moment in stroke patients(all P<0.05 and ρ>0.5).Conclusion:In this study,it was found that the change of acromion-pelvic an-gle during walking in stroke patients decreased compared with that of healthy people,and the movement pattern was mainly in phase.From the perspective of biomechanics,the coupling relationship between kinematics and dynamics of lower limbs is understood,and hip strategy is the main focus.关键词
