objective to evaluate the value of infrared thermography in the diagnosis of injuries in such soft tissues as neck,shoulder,waist,leg,elbow and wrist.methods infrared thermograph (type wp-95) was used to do general physical check up for 221 young soldiers with a regular military training history ranging from 1 to 5 years,whose infrared thermograms were then compared with those of 100 new recruits without any military training experience.results there were abnormal thermograms on 180 (81.45%) of the 221 cases and 6 (6%) of the 100 new recruits （p.05.all of the 186 cases with abnormal thermograms were x-rayed with only 28 cases(i.e.15.05%) abnormal.there was a distinct difference between the two methods of physical check-up (p.05).conclusion infrared thermography manifests distinctive abnormal thermograms of soft tissue injuries suffered from military training,providing definite diagnostic message for clinic.to utilize infrared thermography correctly is of vital importance in ensuring the health of servicemen.

目的 探讨软组织损伤颈、肩、腰、腿、肘、腕红外热像图的诊断价值。方法应用wp-95型红外热像仪，对221例常规军事训练1～5年的年轻干部及战士进行红外热像仪的全身检查，并与刚入伍未参加训练的新兵100例进行对照。结果 221例经红外热像图检查发现颈、肩、腰、肘、腕出现异常热像图的有180例，占81.45%；而100例新战士仅有6例颈、肩、腰、肘、腕出现异常热像图，占6.00%，两者比较差异有显著性（p＜0.05）。186例异常热像图受检者全部做x线摄片检查，x线摄片异常者仅28例，占15.05%，两者检查比较差异有显著性（p.05）。结论红外热像图对军事训练所致软组织损伤有其独特的异常热像图，为临床提供明确的诊断信息，正确的使用红外热像图，对保证部队广大指战员的健康水平有着重要作用。
