Objective: To observe the effect of health education and inversion traction on neck disability index(NDI) in workers with video display terminals(VDT). Method: One hundred and fifty-five employees who spent at least 40 hours per week with VDT were divided into observation group(N=85) and control group(N=70). The observation group received health education and 21 subjects of them also accepted inversion traction in their workplace, and were- followed up Observed half a year later. NDI scores of both groups were evaluated before education and after six months. Result: Half a year later,NDI scores of observation group and control group were 9.98%±6.55% and 13.97%± 7.53% respectively. There was significant difference between two groups(P0.01). The drop rate of NDI scores of the traction group, education group and control group were 45.80%, 25.12% and-11.63% respective- ly. The rate of traction group was significantly higher than simple education group(P0.01). Conclusion: The results suggest that professional health education can effectively reduce NDI scores in work- ers with VDT and the education with inversion traction is more effective.
