Abstract:
Objective To explore the correlation between plantar pressure and walking function in hemiplegic stroke patients.Methods Thirty hemiplegic patients with stroke (a hemiplegic group) and thirty age-matched healthy persons (a control group) were recruited.Gait and balance function training and assessment system (model:AL-600) were used to quantify the walking velocity,peak plantar pressure at heel-strike and push-off periods and displacement of center of pressure (DCOP) of all subjects during walking.The asymmetry of gait was calculated.Two independent sample t-test were used to compare the walking velocity,peak plantar pressure and DCOP for the two groups.Pearson correlation coefficients were applied to analyze the correlation between the walking velocity and peak plantar pressure and DCOP.Results The walking velocity,the peak plantar pressure at heel-strike and push-off periods and DCOP of the hemiplegic group were significantly lower than the control group.In the hemiplegic group,the asymmetry of peak plantar pressure and DCOPx significantly increased,while that of DCOPy became bigger without significant difference.Moreover,the walking capacity of the hemiplegic group was positively correlated with the peak plantar pressure and DCOP.Conclusion Among hemiplegic stroke patients,both the peak plantar pressure at heel-strike and push-off periods lower in a way.Their capacity of weight transfer decreases,which is closely related to their walking velocity.
