The aim of the study was to evaluate the effect of a disease-specific exercise (DSE) on temporomandibular joint (TMJ) function and neck mobility in TMJ dysfunction associated with ankylosing spondylitis (AS). Ten AS patients (seven males and three females) with TMJ dysfunction were recruited for this study. The DSE included exercises to correct head and neck posture and to improve the flexibility of the neck and TMJs. The patients attended treatment three times a week for 4 weeks, averaging 1 hour each session. Assessments were performed pretreatment, posttreatment, and 6 weeks after the completion of treatment. General physical status was assessed by four clinical measures (tragus-to-wall distance, modified Schober test, lumbar side flexion, and intermalleolar distance), the Bath ankylosing spondylitis function index (BASFI), and the Bath ankylosing spondylitis disease activity index. The main outcome measures included TMJ function (craniomandibular index (CMI)), and neck mobility (flexion, extension, rotation, and lateral rotation). None of the measures of general physical status, with the exception of BASFI, were significant1y different between the pretreatment, posttreatment, and 6-week follow-up (p>.05). However, CMI and all neck movements, except for extension, significant1y improved after the treatment (p<.05). These improvements were maintained during the follow-up period. The DSE used in the present study seems to be a clinical1y useful method for managing patients with symptoms from the stomatognathic system in AS. Further studies with more subjects and longer treatment times, including the follow-up period, will be conducted to validate these findings.

정확한 라스트를 제작하기 위하여, 시간대별 발의 변형을 고려한 데이터가 필요하다. 발은 개인의 특성에 따라 차이가 있으나, 정확한 라스트 개발을 위해 체중이 부하되지 않은 상태와 체중을 부하하고 양측 발로 체중을 지지하고 있을 때 발을 측정함으로 발과 기간 대에 따른 관계를 도출해내야 한다. 이 연구는 발길이(foot length), 볼너비(ball width), 볼둘레(ball girth) 뿐만 아니라 발등둘레(foot-dorsum girth), 종골하 지방패드의 너비(heel-pad width) 및 높이(heel-pad height) 등을 측정, 분석하여 기능성 라스트 제작을 위한 기반을 제공한다.
