Infrared Heat Map Technology And Tcm Syndrome Type Of Lumbar Disc Herniation Study

ObjectiveLDH is a common and frequently-occurring disease in orthopedics, It is the most common reason of lumbar and leg pain. Statistics demonstrated that 53% of light workers and 64% of heavy workers had lumbar pain in Sweden. 35% of patients had lumbar pain expanded to LDH. Now we know that almost lumbar pain and sciatica due to LDH. Most of the people on LDHwere young and middle-aged people. The patients of LDH suffered from the serious symptom. LDH maked the quiet influence on the patients' life and work. In 1996 statistics of the group of spine surgery in COA demonstrated that there are 485,000 operation of LDH in 608 hospitals of 14 provinces and cities among 1986 to 1996. We can infer that there are 1,000,000 operation of LDH every year in whole nations. 120 Persons of 1,000,000 people get the operation due to the LDH. But the operation of LDH have many complications in early periods. Such as, inflammation of intervertebral disk, and hematoma of vertebral canal, etal. In middle and further periods, the complications were the adhesion in root of nerve, the narrow of vertebral canal in treatment, re-herniation of the lumbar disc, and unstable of the lumbar vertebra. Comparatively, the treatment of LDH with TCM have small pain, less complications, easy acceptance and affirmative effects. Just now the treatment of TCM is applied to the clinic popularly.Even though, the treatment of TCM is applied to the clinic popularly Just now, the TCM duo to the characteristic by itself often have quiet subjectivity on diagnosis and treatments. Usually, the same symptom which is on diagnosis and treatments of different doctor with TCM appears different results. So there is importance that giving a objective basis to the diagnosis of TCM. The experiment mainly investigates the relation between the technology of infrared thermograph to the classification of TCM on LDH. And it offers a objective basis to the diagnosis and treatments of TCM, improves the accuracy of the diagnosis of TCM on LDH and the curative effect of TCM. MethodsFrom September 2004 to august 2006, we gathered 200 cases which were observe group. These cases were patients who came from the hospital of XiangFan affiliated to the Hubei College of TCM, including 132 males and 68 females. The patients were from 34 to 65 years old, and the mean age was 52.4 years old. At the same time, we randomly selected 200 cases who were healthy people as control group. These people were no history of lumbar and leg pain, including 126 males and 74 females. The patients were from 32 to 67 years old, and the mean agewas 53.6 years old. The sex and age were no significant statistical difference between the two groups. Two groups were comparative. All cases were scanned through PFK-800 instrument of medical infrared thermograph. The people who inspected were exposed body. The operater adjusted the distance and observed the colour image from screen. The image must be clear. The range of scanning was spine, back of thigh and back of lower leg. We mainly record the deviation of temperature which were both sides of surfaces at the same place. The patients of L₄- L₅LDH were measured temperature of the surfaces on back of thigh. The patients of L₅-S₁LDH were measured temperature of the surfaces on back of lower leg. The patients of L₄- L₅and L₅-S₁LDH were measured temperature of the surfaces on back of thigh and lower leg. Then, we record the greater one. We compared the temperature of two low limb, measured the greatest deviation of temperature, and record thedeviation. (Observe Group△t = temperature of abnormal—temperature of normal; Control Group△t = temperature of left lower limb—temperature of right lower limb). The people who inspected must be inspected at 9-10 o' clock in the morning. At the same time, the room of inspected must be kept 24℃. Before inspected, The people who inspected must have a rest 30 minutes at the room of inspected.All data were divided into the no difference, tiny difference and high difference in accordance with the criterion we formulate. It help us find out the level of difference with two low limb.Results1,The temperature of two low limb in the people with LDH are more different than the control group. There was significant statistical difference between the two group (P＜0.01). The temperature of two low limb in the people of each classification of TCM are different. However There was no significant statistical difference among them (P＞0.05)2,The temperature of two low limb in the healthy people are normal. The temperature of the abnormal low limb was higher than normal low limb with patients of the classification with qizhixueyu and shiretanzhi. The temperature of the abnormal low limb was lower than normal low limb with patients: of the classification with fenghanshizhi and ganshenkuixu.Conclusion1,We can give the patients with LDH a better clinical diagnose through the technology of infrared thermograph and clinical symptom.2,We can exactly recognize the classification of cold and hot in the bagang of TCM through the technology of infrared thermograph, It offers a objective basis to recognize the classification of cold and hotin the diagnosis and treatments of TCM.
