背景资料。关于老年人背部疼痛对身体机能的纵向影响，人们知之甚少。我们试图确定导致活动受限(即限制背部疼痛)的背痛是否与居住在社区的老年人的下肢生理功能下降有关。在这项具有18个月随访期的前瞻性研究中，参与者(N=659)年龄在70岁或以上，在基线水平上洗澡、穿衣、转身和走路都是独立的。限制背部疼痛，定义为至少卧床半天或因背部疼痛而减少日常活动，这是在每月的电话采访中确定的。在基线和18个月时，使用三种计时的、基于表现的测试(快速步态、椅子站立和脚踏)来评估下肢的身体功能。下肢功能的下降被定义为在基线评估和18个月评估之间这些测试的计时分数的增加。平均(标准差)为1.3(2.3)个月；364(55%)参与者报告0个月，209(32%)报告1-3个月，86(13%)报告4个月或以上。在调整了基线表现评分和其他协变量后，腰背部疼痛的月数与快速步态恶化独立相关(p
Background. Little is known regarding the longitudinal effects of back pain on physical function among older persons. We sought to determine whether back pain leading to activity restriction (i.e., restricting back pain) is associated with decline in lower extremity physical function among community-dwelling older persons.Methods. In this prospective study with an 18-month follow-up period, participants (N = 659) were aged 70 years or older and independent in bathing, dressing, transferring, and walking at baseline. Restricting back pain, defined as staying in bed for at least one-half day or cutting down on one's usual activities due to back pain, was ascertained during monthly telephone interviews. Lower extremity physical function was assessed using three timed, performance-based tests (rapid gait, chair stands, and foot taps) at baseline and 18 months. Decline in lower extremity physical function was defined as an increase in timed scores on these tests between the baseline and 18-month assessments.Results. The mean (standard deviation) number of months with restricting back pain was 1.3 (2.3); 364 (55%) participants reported 0 months, 209 (32%) reported 1-3 months, and 86 (13%) reported 4 or more months. After adjustment for baseline performance score and other covariates, the number of months with restricting back pain was independently associated with worsening rapid gait (p
