摘　　要：目的:探讨患有慢性非特异性腰痛(chronic nonspecific low back pain,CNLBP)消防员和正常消防员在不同感觉条件下自身姿势控制能力的差异,剖析CNLBP消防员姿势控制的特征和问题,以期为CNLBP消防员制订训练康复计划和提升姿势控制能力提供科学依据。方法:以CNLBP组消防员(n=10)和对照组消防员(n=10)为受试者。采用视觉模拟评分量表(visual analogue scale,VAS)、Oswestry功能障碍指数问卷(Oswestry disability index,ODI)评估CNLBP组疼痛和功能障碍程度,并收集所有受试者睁眼、闭眼、睁眼+平衡垫、闭眼+平衡垫站立时压力中心的横向速度(V_(x))、纵向速度(Vy)、路径长度和摇摆速度,通过平板支撑、3 min屈腿仰卧起坐评估消防员的核心力量,对测试结果进行双因素重复测量方差分析与相关性分析。结果:感觉条件对V_(x)(F=51.557,P<0.01,η_(p)^(2)=0.741)、Vy(F=75.846,P<0.01,η_(p)^(2)=0.808)、路径长度(F=76.667,P<0.01,η_(p)^(2)=0.810)和摇摆速度(F=76.592,P<0.01,η_(p)^(2)=0.810)的主效均显著;CNLBP对V_(x)(F=13.154,P<0.01,η_(p)^(2)=0.422)、Vy(F=6.106,P<0.05,η_(p)^(2)=0.253)、路径长度(F=13.059,P<0.01,η_(p)^(2)=0.420)和摇摆速度(F=13.058,P<0.01,η_(p)^(2)=0.420)的主效应均显著;CNLBP和感觉条件对V_(x)(F=11.822,P<0.01,η_(p)^(2)=0.396)、Vy(F=4.961,P<0.05,η_(p)^(2)=0.216)、路径长度(F=9.206,P<0.01,η_(p)^(2)=0.338)和摇摆速度(F=9.203,P<0.01,η_(p)^(2)=0.338)的交互作用均显著。闭眼时,CNLBP组的VAS评分和ODI评分与摇摆速度和路径长度呈显著正相关(P<0.05);闭眼+平衡垫时,CNLBP组VAS评分与和ODI评分与V_(x)、摇摆速度和路径长度呈显著正相关(P<0.05),平板支撑成绩与V_(x)、摇摆速度和路径长度呈显著负相关(P<0.05),3 min曲腿仰卧起坐成绩与Vy、摇摆速度和路径长度呈显著负相关(P<0.05)。结论:1)躯体感觉和视觉双重干扰对CNLBP组消防员的影响最大,同时视觉单一干扰大于躯体感觉单一干扰;视Objective:The paper investigates variations in postural control abilities across different sensory conditions among firefighters with chronic nonspecific low back pain(CNLBP)compared to those without,and scrutinizes the characteristics and challenges of postural control in firefighters afflicted with CNLBP.Its objective is to establish a scientific foundation for developing training and rehabilitation plans aimed at enhancing the postural control abilities of CNLBP-afflicated firefighters.Methods:Firefighters with CNLBP(n=10)contrasting firefighters(n=10)were enrolled as subjects.The former group underwent assessment using the visual analogue scale(VAS)and the Oswestry disability index(ODI)questionnaire to evaluate the degree of pain and functional disability.The V_(x),Vy,path length and sway velocity of the standing pressure center of all subjects were collected under conditions of eyes open,eyes closed,eyes open with a balance pad,and eyes closed with a balance pad.Subsequently,the core strength was evaluated by assessing plank hold and 3 min bent-leg sit-ups,in order for a two-way repeat‐ed measures ANOVA and correlation analysis on the test results.Results:Significant differences emerged in the main effects of sensory conditions on V_(x)(F=51.557,P<0.01,η_(p)^(2)=0.741),Vy(F=75.846,P<0.01,η_(p)^(2)=0.808),path length(F=76.667,P<0.01,η_(p)^(2)=0.810),and sway velocity(F=76.592,P<0.01,η_(p)^(2)=0.810).Moreover,there were significant differences in the main effects of CNLBP on V_(x)(F=13.154,P<0.01,η_(p)^(2)=0.422),Vy(F=6.106,P<0.05,η_(p)^(2)=0.253),path length(F=13.059,P<0.01,η_(p)^(2)=0.420),and sway velocity(F=13.058,P<0.01,η_(p)^(2)=0.420).Additionally,the results revealed interaction effects between CNLBP and sensory conditions on V_(x)(F=11.822,P<0.01,η_(p)^(2)=0.396),Vy(F=4.961,P<0.05,η_(p)^(2)=0.216),path length(F=9.206,P<0.01,η_(p)^(2)=0.338),and sway velocity(F=9.203,P<0.01,η_(p)^(2)=0.338).Under the eyes closed condition,the VAS and ODI scores of the CNLBP-afflicted subjects showed a sig
