腰背痛病人的红外热像观察

An Observation on Infrared Thermograph of Lower Back Pain Patients

目的 通过分析腰背痛病人红外热像的变化 ,为腰背痛的诊断提供客观依据。方法 应用病例对照研究 ,选择腰背痛病人 6 8例 ,对照人员 70例 ,用视觉模拟评分方法 (visualanaloguescale,VAS)记录腰背疼痛评分 ;使用日本产TVS - 2 0 0 0型彩色红外热像仪分别对病例及对照组人员的腰背部进行红外热像观察。结果 病例组与对照组的VAS评分差异有显著性 (P <0 0 1) ;随着年龄增加和工龄延长 ,患腰背痛危险性呈增高趋势。腰背痛病人的腰背部热像图呈现患侧局部片状明显的高温或低温区 ,热像图明显不对称 ,呈现异常热像图或明显异常热像图。结论 红外热像可以通过皮肤温度变化及红外热像图敏感地反映腰背痛病人的热分布及功能状况 。

Objective To provide scientific basis for the diagnosis of lower back pain through the analysis of infrared thermographs.Methods Case control study was carried out with 68 cases and 70 controls.All the subjects were observed by infrared thermograph(TVS-2000 Color Instrument,Japan)for the lower back,and the degree of pain was evaluated by visual analogue scale(VAS).Results Results showed that VAS was significantly different between two groups(P<0 01).The prevalence increased with the increase of age and working age.The infrared thermographs of patients showed local layer of clearly high or low temperature on the pain side denoting obvious asymmetric and abnormal or distinctively abnormal thermographs.Conclusions It indicated that the infrared thermograph could reflect the distribution of heat and the function of lower back muscle by the changes of the skin temperature.It is of important value in the diagnosis of lower back pain.
