Description

The reproducibility of the measurement values was examined in our newly developed apparatus for measuring the foot grasp power. The present study was also aimed at the elucidation of relationship between foot grasp power and body sway or running velocity. Foot grasp power was measured three times in 55 healthy male subjects (average age: 22.1 ± 3.2 years) and 60 healthy female subjects (average age: 21.2 ± 2.2 years). Body sway was measured by GS3000 and running velocity for 30-m distance was recorded. The reproducibility of measurement values of foot grasp power was high, showing intraclass correlation coefficient of 0.973. Foot grasp power was significantly greater in male subjects than in female subjects, which suggests a difference between the sexes. Female subjects exerted a significantly negative correlation, and male subjects tended to show a negative correlation between foot grasp power and body sway. Subjects of both sexes indicated a significantly positive correlation between foot grasp power and running velocity. These results suggest that foot grasp power may play a role in postural stability, and may work for forward movement during running. The results also suggest the clinical applicability of our new apparatus.<br>
