Correlation Of Plantar Pressure And Walking Phase In Post-stroke Hemiplegic Patients

ObjectiveTo analyze the correlation of plantar pressure and walking phase in post-strokehemiplegic patients.MethodsThirty post-stroke hemiplegic patients were recruited for the experimental group.Thesepatients were accorded with the criteria that the subjects can walk10m independently.Thirty healthy adults were selected as control group. Gait and balance function trainingevaluation system was used in time-space parameter and plantar pressure analysis. Themain outcome measure were the peak of plantar pressure in heel strike phase、stancephase and push-off phase with walking, swing time, stance time, swing time ratio,stance time ratio.Plantar pressures were compared between healthy adults andpost-stroke hemiplegic patients,and correlation of plantar pressure and walking phase inpost-stroke hemiplegic patientsResultsThere was no significant difference (P>0.05)in the peak of plantar pressure of left andright lower limbs of normal persons.There were significant differences (P<0.01)in thepeak of plantar pressure of affected and unaffected lower limbs of post-strokehemiplegic patients.Compared to the control group,there were significant differences(P<0.05)in the peak of plantar pressure、swing time ratio(SWTR) and stance time ratio(STR) of post-stroke hemiplegic patients.The SWTR and STR of post-stroke hemiplegicpatients had a positive correlation with the peak of plantar pressure of unaffected lowerlimbs post-stroke hemiplegic patients in heel strike phase、stance phase and push-offphase (P<0.01). The SWTR and STR of post-stroke hemiplegic patients had a negative correlation with the peak of plantar pressure of affected lower limbs post-strokehemiplegic patients in heel strike phase、stance phase and push-off phase （P<0.01).ConclusionPlantar pressure of unaffected and affected lower limbs post-stroke hemiplegic patientshave a high correlation with walking phase.
