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.
