Background: Individuals with calf muscle shortening may have decreased dynamic balance. Objects: This study aimed to investigate the effect of mobilization with movement (MWM) and myofascial release (MFR) on kinematic changes in dynamic balance in individuals with calf muscle shortening.
Methods: Thirteen participants were randomly assigned to the MWM or the mobilization with movement added myofascial release (MWM-MFR) group. The MWM group received treatment with only MWM, whereas the MWM-MFR group was treated with MWM and MFR. Pre- and post-intervention passive range of motion (PROM), maximum reaching lengths, and modified star excursion balance test (MSEBT) results were compared for all participants. Wilcoxon signed-rank test and Mann-Whitney U test were used for statistical analysis.
Results: The results showed significant within-group differences in ankle PROM, but no significant between-group differences. The maximum reaching length in the MWM-MFR group in the posterolateral direction was significantly different before and after the intervention (p = 0.005). This group also showed significantly reduced ankle abduction in MSEBT during the posteromedial direction section 3 (p = 0.007) and posterolateral direction section 5 (p = 0.049) compared with the MWM group.
Conclusion: Combined MWM and MFR intervention improves ankle stability in the coronal plane during the posteromedial and posterolateral forward mo
본 연구는 한반도 풍혈지 식생에 대하여 ZM학파의 식물사회학적 방법을 통해 식물군락의 특성을 밝히고 풍혈지의 보전 및 관리에 필요한 기초자료를 제공을 목적으로 수행되었다. 풍혈지는 지하에 저온층이 존재하는 크고 작은 바위들의 집적지로서, 지표면에 열려진 공극으로부터 자연적인 냉풍이 불어 나와 국소적으로 저온환경이 형성된 지역이다. 63개 식생조사 자료를 이용하여 풍혈지의 식물군락을 구분한 결과, A. 굴참나무-한들고사리군락, B. 신갈나무-박달나무군락, B-1. 졸참나무-가는잎쐐기풀하위군락, B-2. 마가목-인가목조팝나무하위군락, B-3. 털댕강나무-개병풍하위군락, B-4. 전형하위군락의 2개 군락 4개 하위군락으로 구분되었다. DCCA분석 결과, 굴참나무, 쥐똥나무, 느티나무, 분꽃나무 등을 구분종으로 하는 굴참나무-한들고사리군락은 신갈나무, 쉬땅나무, 함박꽃나무, 당단풍나무, 민둥인가목 등을 구분종으로 하는 신갈나무-박달나무군락보다 온량지수와 강수량이 많은 지역과 높은 상관관계를 나타냈다. 인가목조팝나무, 마가목, 흰인가목, 산앵도나무, 산겨릅나무, 퍼진고사리, 전나무을 구분종으로 하는 마가목-인가목조팝나무하위군락과 구분종을 가지고 있지 않은 전형하위군락은 다른 하위군락에 비하여 높은 해발과 많은 강수량 지역에 분포하였으며, 당조팝나무, 털댕강나무, 개병풍, 산토끼고사리, 북분취, 일본잎갈나무 등을 구분종으로 하는 털댕강나무-개병풍하위군락은 인간활동에 의하여 일광 노출이 많은 지역에 분포하였다.
Observations were conducted in Uiseong Binggye-ri Ice Valley of Korea, where a low temperature talus is located. The talus temperature at Ice Hole near the lower end of the talus remained at 0°C until summer or autumn and averaged -0.3°C over 2 years. The talus temperature at Warm Hole was much higher than the external air temperature during autumn and winter. The outflow of warm air at Warm Hole begins in the late summer of fall. The direction of airflow through the talus surface was determined by the relationship between talus temperature and external air temperature. Annual variations in talus temperature and air exchange between the talus and the external environment can be divided into four periods. It was found that the airflow directions at Warm Hole and Ice Hole were not necessarily opposites. The outflows from the talus at Ice Hole and Warm Hole can occur simultaneously.
