The hypothesis in this study was that slow psychomotor reaction time is related to low-back pain. A total of 73 people with chronic low-back pain (CLBP) were studied. Simple reaction time (SRT) and choice reaction time (CRT) were measured. CRT was also fractionated into decision and movement times. Each four variables measured were analyzed by using analysis variants and covariants with two grouping factors (CLBP and gender) with age and height serving as covariates. The CLBP group had longer SRT, decision time, and total CRT than the control group on average. The results did not conflict with our hypothesis. Slow psychomotor speed of reaction may be one factor in the development of CLBP, or slow reaction in CLBP may have resulted from fear responses, depression, or anxiety. Longitudinal studies are needed in the cause-and-effect evaluation of the relation between speed of reaction and CLBP.
本研究的假设是，精神运动反应时间缓慢与腰痛有关。共对73名慢性腰痛（CLBP）患者进行了研究。测量了简单反应时间（SRT）和选择反应时间（CRT）。CRT也被分为决策时间和运动时间。对所测量的四个变量，通过使用方差分析和协方差分析，以年龄和身高作为协变量，采用两个分组因素（CLBP和性别）进行分析。平均而言，CLBP组的SRT、决策时间和总CRT比对照组更长。结果与我们的假设并不矛盾。精神运动反应速度缓慢可能是CLBP发生的一个因素，或者CLBP中的反应缓慢可能是由恐惧反应、抑郁或焦虑导致的。在反应速度与CLBP关系的因果评估中，需要进行纵向研究。
