AIM: With the low back pain patients caused by sports as the subjects, to observe the biomechanical changes in the muscle and lumbar vertebrae tissue in them after sport therapy. METHODS: The experiment was carried out in the Rehabilitation Center of Guangzhou Institute of Physical Education from June 2006 to January 2007. (1) Eighteen patients with low back pain caused by sports training were selected with the informed consent according to the inclusive criteria: diagnosed as chronic low back pain after orthopedics faculty physical examination with an exception of the joint and discogenic low back pain pathological change; the symptom continued in 3 months or more, and no waist surgery or cardiovascular, nervous system diseases was found in near 5 years; no spinal column or lumbar abnormity was found the X film at low back pain vertebra side position, but lumbar lordotic curve was 54.89 +/- 6.12 degrees; the visual analogue scale results showed the ache degree was below 5. (2) They were randomly divided into training group and control group with 9 people in each group. Training group was treated according to the implementation of sport therapy, and the control group took pain killer primarily. (3) All subjects filled in the Roland-Morris disability questionnaire (RMDQ) and Oswestry Disability Index (ODI) before and after treatment. Meanwhile, abdominal and back muscles endurance, the waist movements, lumbar lordotic curve and ache improvement after sports therapy were detected. RESULTS: All 18 patients with low back pain were involved in the result analysis. (1) Before the experiment, there was no significant difference in RMDQ and ODI scores, abdominal and back muscles endurance, waist movements, and lumbar lordotic curve between two groups, but after the experiment, there were significant differences (p < 0.05, p < 0.01). (2) RMDQ and ODI points, abdominal and back muscles endurance, the waist movements, and lumbar lordotic curve were remarkably different in the experimental group before and after the experiment (p < 0.05, p < 0.01), but no difference was found in control group (p > 0.05). (3) After the experiment, the pain in 8 of 9 people in the experimental group was alleviated, and the illness condition was improved; however, in control group, only 3 persons' ach was alleviated, but the condition was not improved. CONCLUSION: (1) The sport therapy that pays more attention to strengthen the abdominal and back muscles strength has obvious curative effect on low back pain. (2) The evaluation of RMDQ and ODI for the patients with low back pain is of high accuracy and convenience for the comparison.
