A Population-based Study on Motor Performance in Elderly Men

연구배경: 70세와 78세인 두 cohorts에서의 행동수행(Motor Performance)을 비교하였다. 방법: Sweden Gotheborg의 1926년 출생 cohort 170, 1934년 출생 cohort 134, 전체 307명의 남자노인에서 optoelectronic technique를 사용하여 Postural- Locomotion-Manual test를 시행하여 행동수행(Motor performance)을 측정하여 비교하였다. 결과: 1926 cohort와 1934 cohort에서 Movement time과 Manual phase, Simultaneous index에서 통계적으로 의의 있는 차이가 있었고(P＜0.05), postural phase와 locomotion phase에서는 두 cohorts 사이에 통계적으로 의의 있는 차이가 없었다. 결론: 남성노인의 행동수행(Motor Performance)에서 78세 노인에서 70세 노인에 비해 떨어졌으며 Movement time과 arm movement와 motor coordination이 몸을 일으키는 시간과 앞으로 걸어가는 시간(the time for raising the body and walking forward.)에서 보다 더 의의 있게 떨어졌다.

Background: To compare the motor performance of cohorts, born 8 years apart, when they were at equivalent ages 70, 78. in Gotheborg, Sweden Methods: A total 307 elderly men with relatively healthy who were from two birth cohorts between 1926(170) and 1934(137) were selected. Their motor performance was measured by the Postural-Locomotion-Manual test, using optoelectronic technique. Results: Individuals in older cohort were found significant differences in the movement time, manual phase of PLM test, and simultaneous index compared with younger cohort (P＜0.05) but non-significant in postural phase and locomotion phase between two cohorts. Conclusion: Motor performance in elderly men is decreased in more aged population than younger aged population and the movement time and the arm movement and the motor coordination is a potent influence comparing to the time for raising the body and walking forward.
