Falls affect approximately one in three older people, and foot problems are amongst the modifiable potential risk factors.
what are the associations between foot and ankle functional and structural characteristics with falls in community-dwelling older adults?
One hundred eighty-seven community-dwelling older adults (106 females) aged 62-90 years (mean 70.5 ± 5.2) from Isfahan, Iran were recruited. Foot and ankle structure and function (including foot posture, range of motion, muscle strength, deformity, pain and plantar loading patterns during walking) were measured. Fall history was documented in the preceding year. Univariate analyses compared fallers and non-fallers on all variables to determine significant differences and logistic regression analysis identified variables independently associated with falls.
Seventy-four participants (39.9 %) had experienced a fall in the previous year. Logistic regression analysis revealed that less first metatarsophalangeal joint extension (odds ratio 0.82, 95 % CI 0.73-0.91), less plantarflexor muscle strength (odds ratio 0.29, 95 % CI 0.15-0.55), greater pressure-time integral in the medial forefoot (odds ratio 2.65, 95 %CI 1.10-6.38), greater center of pressure velocity in the forefoot (odds ratio 1.27, 95 % CI 1.07-1.49) and greater foot pain (odds ratio 1.09, 95 % CI 1.02-1.16) were significantly and independently associated with falls after accounting for physiological falls risk factors.
We have identified several structural and functional foot and ankle characteristics associated with falling in older people. Future development of interventions to help prevent or treat these potentially modifiable risk factors may help decrease the risk of falling in this population.
跌倒影响大约三分之一的老年人，而足部问题是可改变的潜在风险因素之一。
社区居住的老年人中，足部和踝关节的功能和结构特征与跌倒之间有什么关系？
从伊朗伊斯法罕招募了 187 名年龄在 62-90 岁（平均 70.5±5.2）的社区居住的老年人（106 名女性）。测量了足部和踝关节的结构和功能（包括足弓、运动范围、肌肉力量、畸形、疼痛和行走时的足底负荷模式）。在过去的一年中记录了跌倒史。单变量分析比较了跌倒者和非跌倒者在所有变量上的差异，以确定显著差异，并进行逻辑回归分析确定与跌倒独立相关的变量。
74 名参与者（39.9%）在过去一年中经历过跌倒。逻辑回归分析显示，第一跖趾关节伸展度较小（优势比 0.82，95%置信区间 0.73-0.91），跖屈肌力量较小（优势比 0.29，95%置信区间 0.15-0.55），前脚内侧压力-时间积分较大（优势比 2.65，95%置信区间 1.10-6.38），前脚中心压力速度较大（优势比 1.27，95%置信区间 1.07-1.49）和更大的足部疼痛（优势比 1.09，95%置信区间 1.02-1.16）在考虑生理跌倒风险因素后，与老年人跌倒显著且独立相关。
我们已经确定了一些与老年人跌倒相关的结构和功能的足部和踝关节特征。未来开发有助于预防或治疗这些潜在可改变风险因素的干预措施，可能有助于降低该人群的跌倒风险。
