Abstract

OBJECTS: The purpose of this study is to estimate the values of foot pressure of the stance phase during a gait cycle in hemiplegic gait. METHOD: Thirty patients who had a stroke and forty healthy adults were evaluated by the EMED-SF system to analyze the stance phase of hemiplegic gait. The stance phase was evaluated by 6 points according to the foot pressure and center of pressure proposed by Lee et al.2)
RESULTS
1) In hemiplegics, the stance time of involved limb decreased compared with that of the uninvolved limb and increased that of control groups (p<0.05). 2) In hemiplegics, the midstance time increased but the loading response and terminal stance decreased compared with the uninvolved limb and controls (p<0.05). 3) In hemiplegics, the midstance time decreased and the loading response and terminal phase increased according to the increased Brunnstrom stage (p<0.05).
CONCLUSION
The results showed that an analysis of stance phase by the measurement of plantar pressure was a valuable parameter in the gait analysis of hemiplegic patients.
