Abstract

OBJECTIVE
To determine if physical factors (age, sex, weight, foot length) affected anteroposterior and intersidal weight- bearing pattern on footplate in standing posture and duration of stance phase at walking. METHOD: Participants were 578 healthy adults (250 men, 328 women). All participants were tested by Gaitview? (Alfoots, Seoul, Korea) which measure anteroposterior, intersidal weight-bearing pattern on foot plate and duration of stance phase at walking. Measurements were analyzed to find any relations among physical factors (age, sex, weight, foot length), anteorposterior, intersidal weight-bearing pattern and stance phase.
RESULTS
The age, weight, foot length had no specific relations to anteroposterior weight-bearing pattern (r<0.2, p<0.05). Men had greater weight-bearing pattern on forefoot than women (p<0.01). The higher the age, the more midstance and the more delayed stance phase was noted (r>0.4, p<0.01).
CONCLUSION
There was a significant correlation between sex and anteroposteior weight-bearing pattern. And there was a positive relation between age and stance, midstance phase.
