项目摘要

Walking pattern of healthy elderly was longitudinally studied especially from the qaulity of life(QOL).The rapid increase in the number of aged people in Japan raises problems of maintenance of the QOL in the aged. Walking ability is one of the important parameters of healthy and independent living. The long-term goal of the study is to gather longitudinal information on walking in the elderly and to clarify the relationship between their walking patterns and their QOL. The free gait of fifty-two healthy elderly persons was examined. All the subjects were volunteers, informed concented, were aged 65 years or older, and dwelt in the Kaga community area, Ishikawa Prefecture, Japan. They were healthy and active enough to attend at the study location by themselves. The comparison group of young adults consisted of twenty volunteer students. The percentages of females and males were similar in the two groups. The elderly participants were requiredto carry a pedometer for a week, beginning the next day, in order to count their steps per day. The healthy elderly walked more slowly than the young adults. Their slower speed was largely caused by shorter stride length. Differences were still observed when parameters were presented in the form of dimensionless numbers. Negative correlations between age and speeds, as measured directly or interms of dimensionless forms, and between age and stride length were observed within the elderly group. The number of steps per day also correlated negatively with age within the elderly group. The daily activity could influence the walking ability. The relative stance phase duration correlated positively with age within the elderly group. The elderly were weaker in grip strength and had shorter single-leg balance with eyes open than the young adults. Seasonal differences were observed in some parameters. We need future detailed study in order to clarify the differnces.

从生活质量（QOL）的角度对健康老年人的步行模式进行了纵向研究。日本老年人数量的迅速增加提出了维持老年人生活质量的问题。步行能力是健康和独立生活的重要参数之一。本研究的长期目标是收集老年人步行的纵向信息，并阐明他们的步行模式与生活质量之间的关系。对52名健康老年人进行了自由步态检查。所有受试者均为志愿者，知情且集中，年龄≥ 65岁，居住在日本石川县加贺社区。他们足够健康和活跃，可以自己参加研究。年轻人的对照组由20名志愿者学生组成。两组中女性和男性的百分比相似。老年参与者被要求从第二天开始携带计步器一周，以计算他们每天的步数。健康的老年人比年轻人走得慢。他们的速度较慢主要是由于步幅较短。当参数以无量纲数的形式呈现时，仍然观察到差异。在老年组中观察到年龄与速度（直接测量或无量纲形式测量）以及年龄与步长之间的负相关。在老年组中，每天的步数也与年龄呈负相关。日常活动对步行能力有影响。老年组内相对站立时程与年龄呈正相关。老年人的握力较弱，睁眼单腿平衡能力较短。某些参数存在季节性差异。我们需要进一步的详细研究，以澄清差异。
