摘要

The purpose of the study was to measure the peak pressure under the metatarsal heads (MTH) of young men and women in walking with high resolution pressure system and to determine their reliability. The peak pressure of sixteen health men and women, aged from twenty-one to thirty-five years-old, were measured at the first, second and third metatarsal head by high resolution pressure system for ten repetitions using first-step method. Peak pressure at the second MTH (68.2±43.9 N/cm2 for women, 52.6±21.1 N/cm2 for men) was significantly higher than the first MTH (28.4±13.8 N/cm2 for women, 35.5±18.2 N/cm2 for men) and third MTH (52.2±32.2 N/cm2 for women, 41.7±12.4 N/cm2 for men) (p＜0.05). Coefficient of reliability (COR) at first, second and third MTH were 0.63, 0.94, and 0.89 in women. The number of repetitions needed to make reliability greater than 0.90 at the first and third MTH were 6 and 2. COR at the first, second and third MTH were 0.56, 0.90, and 0.75 in men. The number of repetitions needed to make reliability greater than 0.90 at the first and third MTH were 7 and 3. Our study revealed the normal range and reliability of high resolution plantar pressure were different at the first, second, and third MTH. One to 7 repeated measurements were needed to reach a reliability great than 0.90.
