背景與目的:比較13至22歲各學級體育班及非體育班之在學學生的拇趾外翻角度，以探討承受不同活動強度是否會影響拇趾外翻之角度。方法:本研究受試者共285位，其中156位為體育班學生，129位為非體育班學生，年齡介於13歲至22歲，區分各級學校學生為體育班學生及非體育班 學生，再細分為閩中、高中與大學組。受試者中若有六個月內下肢神經、肌肉及骨酪傷害的病史則予以排除。以量角器徒手測量左右兩腳的拇趾外翻角度。以SPSS12.0統計軟體進行統計，統計 α=0的。結果:體育班學生有36位有明顯拇趾外翻(超過20度) ，占22.6%)，非體育班學18位有明顯拇趾外翻，占14.0吸) ，以卡方檢定達到統計差異(p<0.05)。以共變數分析的統計方法發現體育班及非體育班的因素會影響拇趾外翻的角度，有統計學上的意義(p

Background and Purpose: We conducted a study to compare hallux valgus angle (HA) among 13-22 year-old students in either athletic preparation or general class in northern Taiwan to determine if different levels of physical training associated with different degrees of haIlux valgus. Methods: We recruited 285 subjects (156 athletic preparation students and 129 general class students) whose age were between 13 and 22 years old and these students were classified into junior high school， senior high school， and coIlege subgroups. We excluded subjects who had history of lower extremities neuromuscular or musculoskeletal injuries in the recent 6 months. We measured the haIlux angle of both feet with a goniometer. AII statistical analyses were conducted using SPSS for Windows 12.0 Statistical significant level was set atα=0.05. ResuIts: Thirty-six cases (22.6%) of obvious haIlux valgus (over 20 degree) were noted in the athletic preparation class and 18 cases (14.0%)were noted in the general class. Statistic difference was noted by the Chi-square test (p<0.05).Participating in the athletic class or not is highly associated with the HA angle. Statistic significance was revealed by ANCOVA (p<0.05).Students in the athletic preparation class had larger HA angle than those in general class. ConcIusions: More cases of severe hallux valgus were noted in the athletic preparation class than in the gen eral class. The athletic preparation class students had larger mean haIlux valgus degree than the general class students. Owing to the major difference between the athletic preparation class and the general class is physical activity levels， we believe that physical activity may have a great influence on the developing of haIlux valgus in school age.
