고등학교 발레 전공생의 해부학적 족부 변형에 따른 족관절 가동범위, 기능수행능력, 거골경사각 및 족부 상해 비교 = Comparing Ankle Range of Motion, Functional Ability, Talar Tilt Angle and Foot Injuries between High School Ballet Majors with and without Foot Deformities

다국어 초록 (Multilingual Abstract)

Background: The purpose of the study was to compare and contrast ankle range of motion, functional ability, talar-tilt angle and foot injuries between high school ballet majors with and without foot deformities and to providefundamental data about effective intervention methods for their successful performance and injury prevention.
Methods: Subjects were 18 female high school ballet dancers, eight with foot deformities and ten without footdeformities. For statistical analysis, the independent t-test (SPSS 20.0; SPSS Inc, Chicago, IL, USA) was usedand the significant level of P<0.050 was selected.
Results: 1. Foot injuries of plantar flexion and talar tilt were significantly different between the two groups(P<0.050). 2. The deformity group displayed a higher proportion of mechanical instability compared to that ofthe control group.
Conclusions: Foot deformities in high school students majoring in ballet can have negative effects to the anklejoint, with a strong possibility of ankle instability and foot injuries linked to tarlar tilt, and quite probably, of chronicankle sprain.

연구배경: 본 연구에서는 고등학교 발레 전공생들을 대상으로 족부의 해부학적 변형유무에 따른 족관절 가동범위, 기능수행능력, 거골경사각 및 상해율을 비교해 봄으로써 이들의 성공적인 무용 수행 능력과 상해 예방에 도움을줄 수 있는 효과적인 중재방법의 수립을 위한 기초자료를제시하고자 한다.
방법: 예술고등학교 발레전공학생들 18명을 대상으로 족부의 해부학적 변형유무를 파악하고 변형여부에 따라 족관절 가동범위, 기능수행능력, 거골경사각 및 족부 상해를비교하여 기능적 특성의 차이를 분석하였다. 자료처리방법은 SPSS 20.0 통계프로그램을 이용하였으며 측정된 모든변인의 평균과 표준편차를 산출하여 독립표본 t검증을 이용하여 분석하였다. 모든 통계적 유의수준은 P<0.050으로설정하였다. 또한 빈도분석을 이용하여 그룹 간 상해발생빈도와 발생률을 비교하였다.
결과: 1. 정상집단의 저측굴곡 능력은 변형집단보다 유의하게 큰 것으로 나타났다. 2. 민첩성과 평형성 측정결과 변형집단과 정상집단 간에는 유의한 차이가 나타나지 않았다. 3. 변형집단의 거골경사각은 정상집단보다 유의하게큰 것으로 나타났다. 4. 정상집단보다 변형집단에서는 기계적 불안정성을 가지는 비율이 더 높게 나타났으며, 기형발톱, 티눈, 굳은살에서는 큰 차이를 보이지 않았다.
결론: 고등학교 발레 전공생의 족부 아치의 변형은 발목관절의 저측굴곡력에 부정적인 영향을 미치며 만성적인발목 염좌율을 높일 수 있는 거골경사각과도 관련되어 발목 불안정성 및 족부 상해율을 높일 가능성이 있는 것으로 나타났다.
