Postural transitions have been identified as presenting challenging situations for the elderly.
This study hypothesizes a relationship between age-related factors and postural stabilization performance after a transition movement. In particular, the controlled factors in the experiment are: 1) assistance in living (independent living for community-dwelling subjects vs. assisted living for institutionalized subjects in nursing homes); 2) age of institutionalized individuals, by comparing groups with different age ranges.
Sixty-three institutionalized individuals in nursing homes were recruited (17 in the age range 64-79; 46, including 6 drop-outs, in the age range 80-95). Moreover, seventeen (one drop out) community dwelling subjects (64-79 years) were enlisted. The study focuses on the postural stabilization phase after a "step forward" task.
When comparing age-matched subjects from the two groups, the residents in nursing homes were characterised by a worse stabilization performance: the stabilization time more than doubled, Instability increased by 39 %, and Promptness decreased by 77 %, although there was no significant difference in the quiet erect posture between the groups. No difference was observed when comparing the two age groups of residents in the nursing homes, however a potential confounding effect has been identified in the unequal mortality rates between the two groups.
It is hypothesized that an individual identification of abnormal values of Instability and/or Promptness may inform different rehabilitation approaches.
姿势转换已被确定为老年人面临的具有挑战性的情况。
本研究假设与年龄相关的因素与过渡运动后的姿势稳定性能之间存在关系。特别是，实验中的受控因素是：1）生活辅助（独立生活的社区居住者与养老院中机构化个体的辅助生活）；2）机构化个体的年龄，通过比较具有不同年龄范围的组。
招募了 63 名养老院中的机构化个体（64-79 岁的 17 名；80-95 岁的 46 名，包括 6 名退出者）。此外，还招募了 17 名（1 名退出者）社区居住的个体（64-79 岁）。该研究侧重于“向前跨步”任务后的姿势稳定阶段。
当比较两组中年龄匹配的个体时，养老院中的居民表现出较差的稳定性能：稳定时间增加了一倍以上，不稳定性增加了 39％，及时性降低了 77％，尽管两组之间的安静直立姿势没有明显差异。然而，在比较养老院中两个年龄组的居民时，没有观察到差异，但在两组之间的死亡率不等方面发现了潜在的混杂效应。
假设异常的不稳定性和/或及时性值的个体识别可能会提供不同的康复方法。
