OBJECTIVE: To assess the effect of a three-week intervention (intervention emphasizing diagonal eccentric contraction (IEDEC) and intervention of general exercise (IGE)) on static and dynamic balance abilities, ankle strength and joint position sense at pre- and post-intervention, and at two- and three-week post-intervention. METHODS: Twenty-five participants with ankle instability, including a history of ankle sprain and recurrent episodes of giving way, were enrolled in the study. They were randomly classified into the IEDEC group (n= 12) and the IGE group (n= 13). Dynamic balance was examined using the Y Balance Test, four-way ankle strength was measured, and the static balance was evaluated using the total displacement of the center of pressure (COP). To identify the joint position error, eversion and inversion of the ankle angle were measured. RESULTS: The results revealed significant increases in ankle dynamic stability and strength at two and three weeks post-intervention (p&lt; 0.05). Similarly, the total displacement of the COP differed significantly over time, with a higher COP during the initial measurement than at two and three weeks intervention (p&lt; 0.05) General balance training with IEDEC can improve position sense during ankle inversion (p&lt; 0.05). CONCLUSION: General balance training with IEDEC improved the position sense of the inversion. Combined therapeutic intervention, such as with the manual technique, could be a beneficial approach to maximize the treatment effects.<\/jats:p>","DOI":"10.3233\/bmr-200058","type":"journal-article","created":{"date-parts":[[2020,10,20]],"date-time":"2020-10-20T10:48:07Z","timestamp":1603190887000},"page":"95-101","source":"Crossref","is-referenced-by-count":10,"title":["A three-week intervention emphasized diagonal eccentric contraction on balance and joint position sense and ankle strength in subjects with ankle instability: A randomized controlled trial"],"prefix":"10.1177","volume":"34","author":[{"given":"Du-Jin","family":"Park","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, College of Health Sciences, Catholic University of Pusan, Busan, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byeong-Jo","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, College of Nursing, Healthcare Sciences and Human Ecology, Dongeui University, Busan, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong-Hun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, College of Biomedical Science, Masan University, Changwon, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Se-Yeon","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, College of Biomedical Science, Kaya University, Gimhae, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"key":"10.3233\/BMR-200058_ref1","first-page":"381","article-title":"Ankle injuries among United States high school sports athletes, 2005\u20132006","volume":"42","author":"Nelson","year":"2007","journal-title":"Journal of Athletic Training."},{"issue":"1","key":"10.3233\/BMR-200058_ref2","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1177\/1938640013509670","article-title":"Prevalence of chronic ankle instability in high school and division I athletes","volume":"7","author":"Tanen","year":"2014","journal-title":"Foot and Ankle Specialist."},{"key":"10.3233\/BMR-200058_ref3","first-page":"394","article-title":"Factors contributing to chronic ankle instability: a strength perspective","volume":"37","author":"Kaminski","year":"2002","journal-title":"Journal of Athletic Training."},{"key":"10.3233\/BMR-200058_ref4","doi-asserted-by":"crossref","first-page":"154","DOI":"10.1016\/j.humov.2014.12.004","article-title":"Alterations in stride-to-stride variability during walking in individuals with chronic ankle instability","volume":"40","author":"Terada","year":"2015","journal-title":"Human Movement Science."},{"issue":"2","key":"10.3233\/BMR-200058_ref5","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1136\/bjsports-2016-096534","article-title":"Therapeutic interventions for improving self-reported function in patients with chronic ankle instability: a systematic review","volume":"51","author":"Kosik","year":"2017","journal-title":"British Journal of Sports Medicine."},{"issue":"2","key":"10.3233\/BMR-200058_ref6","doi-asserted-by":"crossref","first-page":"301","DOI":"10.12965\/jer.1836082.041","article-title":"Effects of ankle strengthening exercise program on an unstable supporting surface on proprioception and balance in adults with functional ankle instability","volume":"14","author":"Ha","year":"2018","journal-title":"Journal of Exercise Rehabilitation."},{"issue":"7","key":"10.3233\/BMR-200058_ref7","doi-asserted-by":"crossref","first-page":"662","DOI":"10.4085\/1062-6050-555-16","article-title":"Two 4-Week Balance-Training Programs for Chronic Ankle Instability","volume":"53","author":"Anguish","year":"2018","journal-title":"Journal of Athletic Training."},{"key":"10.3233\/BMR-200058_ref8","doi-asserted-by":"crossref","unstructured":"Adler SA, Beckers D, Buck M.
