주관절 굴곡각도에 의한 집는 힘의 생체 역학적 분석 = Analysis of Biomechanics for Pinch Strength due to Elbow Flexion Degree

다국어 초록 (Multilingual Abstract)

Purpose：We have investigated to analysis biomechanics for pinch strength due to elbow flexion degree. Methods：Pinch strength was measured by Electro Dynamometer(G-100) using four elbow flexion degree (0°, 45°, 90°, 135°). Results：In experimental results, we found that pinch strengths were 5.4kg(0°), 4.8kg(45°), 5.6kg(90°) and 5.2kg(135°), respectively. The Pinch strengths got maximum at 90°degree, minimum at 45°degree. We have calculated F1 values using Σ T-0. As a result F1 values were 540N(0°), 480N(45°), 560N(90°) and 520N(135°), respectively. F1 values got maximum at 90° degree, minimum at 45° degree. Data curve line of F1 values was increased in 45~90 section and decreased in 0~45, 90~135 sections, respectively. Conclusion：F1 (Flexor digitorum superficialis and profundus) values were 10 times bigger than pinch strengths. Data curve line of F1 values was similar to active length-tension curve in 45~90, 90~135 sections.
