建立國內正常青年的足底壓力常模對於未來足底壓力的測量具有指標作用，而病 態的足底壓力測量亦需與正常足底壓力數值相比較才有意義，本研究的目的即在於瞭解正常 年輕男性跑步與走步之足底壓力，並期以此為開端，逐漸建立國內正常青年的足底壓力常模 ，受試者窟二十名健康成年男性， 年均年齡 23.9 ± 3.3 歲、平均身高 173.4 ± 4.8 公 分、平均體重 69.0 ± 7.4 公斤、平均腿長 87.6 ± 2.8 公分。使用 EMED-pedar 足底壓 力測量系統，在 Trackmaster TM500 型的跑步機上測量在跑步（速度 2.66m/s ）及走步（ 速度 1.33m/s ）時的足底壓力相關數值。 結果顯示最大足底壓力、平均足底壓力及壓力─ 時間積分在跑步機皆發生在第一跖骨區（ PPP=24.83 ± 5.39 N/Cm �插A MPP=14.14 ± 2.93 N/Cm， PTI=2.99 士 0.59 Ns/Cm �插^， 而走步時則發生在第二蹠骨區（ PPP=19.49 ± 5.40 N/Cm �插AMPP=11.40 ± 2.47 N/Cm，PTI=4.23 ± 0.98 Ns/Cm �插^。力量分佈及 力量─時間積分方面均以足跟區為最大（跑步時 FD=470.30 ± 74.18N， FTI=31.36 ± 5.76 Ns：走步時 FD=389.07 ± 51.52 N， FTI=67.04 ± 12.67 Ns ）。 壓力中線路徑則 自足跟區中心偏外起始，而由第二蹠骨區離開。 在 paired-t test 統計分析結果顯示，跑 步與走步在最大足底壓力、平均足底壓力及力量分佈等參敷，除最大足底壓力之其他腳趾區 外，其餘皆有顯著差異（ p<0.05 ）。本實驗結果可做為國內青年跑步及走步的足底壓力常 模之參考。本實驗亦顯示不同儀器間與不同速度間皆需要有不同的足底壓力常模。

　　　　　To establish plantar pressure data base is an index for the measurement of plantar pressure in the future. It' s significance for the measurement of pathological plantar pressure to compare with the data base of normal plantar pressure. But there is no complete data base of normal plantar pressure in Taiwan. The study investigated the characteristics of the plantar pressure distribution in healthy young adults when running and walking, and from now on we can establish the plantar pressure data base of the normal young adults in Taiwan step by step. Twenty healthy male subject (Age 23.9 ± 3.3 yr., Wt. 69.0 ± 4.8 kg, Ht. 173.4 ± 4.8 cm, Leg length 87.6 ± 2.8 cm) were tested on the treadmill (Trackmaster, TM500) by using EMED-pedar to measure the plantar pressure in running (2.66m/s) and walking (1.33m/s). The results revealed that the peak plantar pressure, the mean plantar pressure and the pressure-time integral occurred at the region of the first metatarsal head during running, but occurred at the region of the second metatarsal head during walking. It' s showed the peak force distribution and the maximum values of the force-time integral were recorded at the heel region for both during running and during walking. The gait line started from the lateral heel and ended at the second metatarsal head. Except for the peak plantar pressure of the lesser toes region, the paired-t test revealed that the peak plantar pressure, the mean plantar pressure, the force distribution, the pressure-time integral, and the force-time integral at seven selected foot regions were significantly different (p<0.05) between running and walking. These results could be regarded as reference for the plantar pressure data base of the young healthy Taiwan adults in running and walking. The results also indicated the necessity to establish different plantar pressure data bases for different instruments and for different speeds.
