This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Older adults with "high level gait disorders" have abnormal gait and an excessive fear of falling; however, clinical neuro-motor examination typically does not reveal any obvious underlying impairment. We are characterizing the changes in gait dynamics in this population compared to aged-matched controls and studying the effects of different interventions. These patients walk more slowly, with increased stride-to-stride variability and impaired gait dynamics. Many of these changes are associated with fear of falling. Of note, among the patients with high level gait disorders, about 50% reported falling. Fear of falling, gait speed, gait variability and many other measures were similar in those subjects who reported falling and those who did not. Of note, a fractal scaling index of gait was successful in discriminating between fallers from non-fallers. Ongoing work is directed at further assessing risk of falling in these elderly fallers with high level gait disorders, developing new techniques for quantitatively characterizing gait in these patients, determining the mechanisms responsible for the gait changes and fear of falling, and evaluating the effects of different interventions.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子弹和调查员（PI）可能已经从其他NIH来源获得了主要资金，因此可以在其他清晰的条目中代表。列出的机构适用于该中心，这不一定是调查员的机构。患有“高水平步态疾病”的老年人的步态异常，对跌倒的恐惧过多。但是，临床神经运动检查通常并未显示出任何明显的潜在障碍。与老年匹配的对照相比，我们正在表征该人群中步态动力学的变化并研究不同干预措施的影响。这些患者的行走速度较慢，步步性变化的变化增加和步态动力学受损。这些变化中有许多与害怕跌倒有关。值得注意的是，在患有高水平步态疾病的患者中，约有50％的人报告下降。害怕跌倒，步态速度，步态变异性和许多其他措施在报告下降的受试者中相似，而那些没有的人则相似。值得注意的是，步态的分形缩放指数成功地区分了非男人的堕落者。正在进行的工作是进一步评估这些患有高水平步态疾病的老年堕落者的风险，开发了用于定量表征这些患者步态的新技术，从而确定了导致步态变化和恐惧下降的机制，并评估了不同干预措施的影响。
