【摘要】：通过研究牙科坐椅的倾仰角度变化对人体肌电影响及背部压力分布的影响,为牙科医生手术过程中权衡牙科手术需要与病人舒适性提供有力的参考依据。根据牙科医生建议,针对10个实验对象,采用MP150多导电生理记录仪测试不同倾仰角度下人的表面肌电,采用BPMS5315O体压测试系统,测试不同倾仰角度下人体背部压力分布及人体舒适性的主观评价,并对所得肌电指标压力分布指标采用编程软件Matlab 7.1和统计分析软件SPSS 18.0进行数据处理。获得了积分肌电值(IEMG)靠背压力变化规律,确定了基于表面肌电及体压分布综合地判断牙科手术中病人舒适性的指标,并得到牙科手术中病人最舒适的座椅倾仰角度为50°(±5°)。
[Abstract]:The effect of tilt angle of dental chair on electromyography and back pressure distribution was studied. To provide a strong reference for the dental surgeon to weigh the needs of dental surgery and patient comfort. According to the recommendations of the dentist, 10 subjects were selected. The surface electromyography (EMG) of human at different tilt angles was measured by MP150 multi-conductive physiological recorder, and the BPMS5315O body pressure measurement system was used. To test the subjective evaluation of back pressure distribution and human comfort under different tilting angles, and to evaluate the electromyoelectric index (EMG). The pressure distribution index was processed by programming software Matlab 7.1 and statistical analysis software SPSS 18.0. The variation of back pressure was used to determine the index of comfort of patients in dental surgery based on the distribution of surface electromyography and body pressure. The most comfortable tilting angle was 50 掳(卤5 掳).
