Establishment and validation of an indicator system of risk assessment for mechanical cuts / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To establish an indicator system of risk assessment for mechanical cuts, and to validate the system using examples.</p><p><b>METHODS</b>An indicator system was proposed by the expert investigation method. The index weight, expert authority coefficient, and degree of coordination were determined. The reasonability and stability of the expert questionnaire were evaluated by the reliability analysis. Some on-site examples were given to validate the indicator system.</p><p><b>RESULTS</b>An indicator system containing 3 first-class indicators, 10 second-class indicators, and 34 third-class indicators was obtained by screening indicators using the boundary value method and the assignment transformation method. The average expert authority coefficient was 0.79. The average expert coordination coefficient was 0.47. The overall reliability coefficient was 0.884. The scores obtained using the indicator system were significantly correlated with the actual injury results in six workplaces (r=0.866, P<0.01).</p><p><b>CONCLUSION</b>The indicator system of risk assessment for mechanical cuts proposed in this study is reasonable and highly consistent with the actual injury results. However, this indicator system still needs further validation and optimization.</p>

Sexual dysfunction and quality of life after spinal cord Injury / 中华物理医学与康复杂志

Objective To investigate sexual dysfunction and its rehabilitation,as well as quality of life in patients after spinal cord injury(SCI). Methods Sixty-two male patients with SCl were assessed with a 5-item version of the International Index of Erectile Function(IIEF-5),an especially-designed sexual function scale,and the World Health Organization's quality of life questionnaire(WHO-QOL).Their results were compared with those of 146 other patients with work injuries hospitalized in the same period.Results 77.9% of 62 cases had moderate to severe erectile dysfunction.though more than half of them remained sexually active.52.7% had attempted sexual intercourse,but only 19.5% succeeded,and only 14.5% obtained sexual satisfaction.69.1% of the 62 patients had psychological symptoms,and 27.27% had family problems.Their average score on the WHO-QOL was significantly lower than that of the other disabled workers.There were significant differences between the two groups with regard to quality of life.especially in the physiological and social relationships domains. Conclusion Most male patients with SCI had sexual dysfunction and decreased quality of life.Sexual dysfunction rehabilitation of SCI patients needs urgent strengthening.

Effects of Multidisciplinary Rehabilitation on Early Heterotopic Ossification of Patients with Traumatic Elbow Joint Iinjury / 中国康复理论与实践

@#Objective To observe the effects of multidisciplinary rehabilitation on early heterotopic ossification of patients with traumatic elbow joint injury.Methods 80 work injury patients of early heterotopic ossification after traumatic elbow joint injury were randomly divided into the experiment group(42 cases) and control group(38 cases).The experiment group received multidisciplinary rehabilitation,including physical therapy,occupational therapy,physical factor therapy,traditional Chinese medicine,ward rehabilitation and vocational training.The control group was treated with pain killer and diminish inflammation medicine and median frequency electrical therapy.Range of motion(ROM) of joint and visual analogue scale(VAS) were separately assessed before and after 3 months treatment.Results After 3 months treatment,ROM and VAS of the experiment group were significantly changed compared with admission(P<0.01).The effectiveness of the experiment group was superior to that of the control group(P<0.05).After discharge,39 cases returned to primary work,3 cases changed work in the experiment group,and after 1 year follow-up,no case needed to receive operation.Conclusion In the early stage of heterotopic ossification after traumatic elbow joint injury,multidisciplinary rehabilitation can significantly relax clinical signs,improve functions and make the work injury patients return to work.
