摘要

國際標準舞不只是ㄧ種社交活動，近年來在舞蹈競技中和日常運動項目，也漸成趨勢，但是跳國際標準舞會產生足部疼痛與足底運動傷害卻時有所聞，本研究即對此現象進行調查，並尋求改善之道。研究針對初學舞者，使用問卷及足底影像掃描進行現況調查，問卷受測者29人，其中22人接受足印掃描，得知造成舞者足部疼痛及平衡感不佳的原因為：(1) 穿著舞鞋及有跟的鞋子、(2) 扁平足弓、(3) 節奏較快的拉丁舞類、舞步較快的恰恰恰舞。穿著舞鞋及有跟的鞋子跳國際標準舞有顯著造成足底疼痛疲勞並顯著造成平衡感不佳。國際標準舞之舞者足弓型態多為輕度至重度之扁平足 (合計佔62.1%)。這些舞者，跳國際標準舞有顯著造成足底疼痛疲勞。
本研究參考相關的文獻與現況調查、足底影像掃描等資料，針對重度扁平足與輕度扁平足設計出兩款國際標準舞專用足弓墊，使用硬度30之EVA材料製作成品，以供實驗之用。
後測實驗的對象共20人，篩選自現況調查之受測者。實驗組9人，穿著同款舞鞋跳舞一週填寫使用問卷後，依照受測者足弓扁平程度加入實驗足弓墊使用二週後填寫使用問卷；對照組11人，於相同時段穿著慣用鞋跳舞，並填寫兩階段足底疼痛問卷。經由問卷資料分析，顯示足弓墊針對扁平足舞者可以改善疼痛感39.63%、改善平衡感46.30%、改善足底疲勞39.37%。因此，建議扁平足舞者可於舞蹈時選擇適合之足弓墊。舞鞋製造或輔具廠商可就足弓墊材質、面積、厚度探討未來考慮改善的方向。

In recent years, ballroom dancing has emerged from a social activity to become a dance competition and a daily physical sport participated in by many with increasing popularity. However, just like any other regular sport, incidents such as foot discomfort and injuries are not uncommon among ballroom dancers. In this research, a field investigation comprised of a survey and foot image scanning for subjects was conducted. Out of the 29 subjects who completed the survey, 22 took part in a footprint scanning process. From the results of the investigation, we were able to identify the causes that lead to foot discomfort and poor balance for dancers: (1) wearing dance shoes or shoes with heels; (2) flat foot arches; (3) specific dance routines such as the quick tempo Latin or the lively Cha-cha-cha. Findings of the investigation showed that a substantial number of ballroom dancers wearing dance shoes or shoes with heels suffer from foot discomfort, fatigue and poor balance. In addition, most of the subjects (who practice ballroom dancing) in fact have flat foot arches (62.1%). Subjects with flat feet (regardless of severity of the condition) have responded that they have experienced noticeable foot discomfort and fatigue while practicing ballroom dancing.
Based on the content of literatures referred for the purpose of this research, the results of the field investigation and the data from subjects’ foot image scanning, two types of arch support were designed and developed using EVA materials with a hardness of 30 specially designed for ballroom dancers with varying degree of flat feet.
20 subjects were screened and selected from the field investigation to participate in the post-test experiment. 9 subjects were placed in the experimental group and asked to wear identical dance shoes for a week while dancing. These subjects were then asked to complete a questionnaire. At the same time, subjects were given the experimental arch support we have developed in this research according to the severity of their flat feet. They were asked to complete another questionnaire after two weeks of usage. The 11 subjects in the compare group were asked to wear their own shoes (which they were used to wearing) while dancing during the period of the experiment before completing the two-stage questionnaire on their experience of foot discomfort. Results from the analyses of these questionnaires indicated that the arch support developed for the research alleviated painful sensations for flat feet dancers by 39.63%, improved their balance by 46.30% and reduced foot fatigue by 39.37%. However, subjects have also brought up the point that it took a significant period of time before they become accustomed to using the arch support due to comfort factors. In other words, manufacturers of dance shoes or assisting devices could improve upon their products in the areas of material application, surface area and thickness design.
