허리보호대 착용에 따른 하지와 허리의 근 활성도및 각도 비교에 관한 연구 = A study on the comparison of muslce activity and angles of lower back relation to back waist protection

다국어 초록 (Multilingual Abstract)

Objective: The objective of this study was to examine whether there are differences in low back and lower extremity muscle activity between when a back belt is worn and when no waist protection band is worn while moving patients.
Method: This study was conducted on 50 physical therapists who were working in areas where patients should be moved in C Hospital in located in Gyeonggi-do. The physical therapists were randomly divided into two groups of 25 persons each and the groups moved patients from their wheel chairs to tables wearing a back belt and without wearing any back belt respectively. The muscle activities of the trunks and lower extremities of the subjects were measured using electromyographs while the subjects were moving patients and the angles of their trunks and lower extremities were obtained through video taping and goniometers. Independent sample t-tests were conducted in order to examine differences between the two groups.
Results: In the experiment, the group of those who were wearing a back belt and the group of those who were not wearing any back belt did not show any significant difference in muscle activity.(p>.05) However, the group of those who were wearing a back belt and the group of those who were not wearing any back belt showed significant differences in trunk and lower extremity angles.(p<.05) Conclusion: The results mean than back belt make proper postures by reducing lumbar bending angles and increasing knee bending angles when the subjects are moving patients.
