To identify differences in health factors, neuromuscular attributes, and performance-based mobility among community-dwelling older adults with symptomatic lumbar spinal stenosis; and to determine which neuromuscular attributes are associated with performance-based measures of mobility.
Cross-sectional; secondary data analysis of a cohort study.
Outpatient rehabilitation center.
Community-dwelling adults aged ≥65 years with self-reported mobility limitations and symptomatic lumbar spinal stenosis (N=54).
Not applicable.
Short Physical Performance Battery score, habitual gait speed, and chair stand test.
Symptomatic lumbar spinal stenosis was classified using self-reported symptoms of neurogenic claudication and imaging. Among 430 community-dwelling older adults, 54 (13%) met criteria for symptomatic lumbar spinal stenosis. Compared with participants without symptomatic lumbar spinal stenosis, those with symptomatic lumbar spinal stenosis had more comorbidities, higher body mass index, greater pain, and less balance confidence. Participants with symptomatic lumbar spinal stenosis had greater impairment in trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion range of motion (ROM), knee extension ROM, and ankle ROM compared with participants without symptomatic lumbar spinal stenosis. Five neuromuscular attributes were associated with performance-based mobility among participants with symptomatic lumbar spinal stenosis: trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion ROM, and knee extension ROM asymmetry.
Community-dwelling older adults with self-reported mobility limitations and symptomatic lumbar spinal stenosis exhibit poorer health characteristics, greater neuromuscular impairment, and worse mobility when compared with those without symptomatic lumbar spinal stenosis. Poorer trunk extensor muscle endurance, leg strength, leg strength asymmetry, knee flexion ROM, and knee extension ROM asymmetry were associated with performance-based mobility among participants with symptomatic lumbar spinal stenosis.
识别有症状的腰椎管狭窄症的社区居住老年人在健康因素、神经肌肉属性和基于表现的活动能力方面的差异；并确定哪些神经肌肉属性与基于表现的活动能力测量指标相关。
横断面研究；队列研究的二次数据分析。
门诊康复中心。
年龄≥65岁、自我报告有活动能力受限且有症状的腰椎管狭窄症的社区居住成年人（N = 54）。
不适用。
简短体能状况量表评分、习惯性步速和椅子站立测试。
根据自我报告的神经源性间歇性跛行症状和影像学检查对有症状的腰椎管狭窄症进行分类。在430名社区居住的老年人中，54名（13%）符合有症状的腰椎管狭窄症标准。与无有症状的腰椎管狭窄症的参与者相比，有症状的腰椎管狭窄症患者有更多的合并症、更高的体重指数、更严重的疼痛和更低的平衡信心。与无有症状的腰椎管狭窄症的参与者相比，有症状的腰椎管狭窄症患者在躯干伸肌耐力、腿部力量、腿部力量不对称、膝关节屈曲活动范围（ROM）、膝关节伸展ROM和踝关节ROM方面有更大的损伤。在有症状的腰椎管狭窄症参与者中，五种神经肌肉属性与基于表现的活动能力相关：躯干伸肌耐力、腿部力量、腿部力量不对称、膝关节屈曲ROM和膝关节伸展ROM不对称。
与无有症状的腰椎管狭窄症的老年人相比，自我报告有活动能力受限且有症状的腰椎管狭窄症的社区居住老年人表现出更差的健康特征、更大的神经肌肉损伤和更差的活动能力。在有症状的腰椎管狭窄症参与者中，较差的躯干伸肌耐力、腿部力量、腿部力量不对称、膝关节屈曲ROM和膝关节伸展ROM不对称与基于表现的活动能力相关。
