Methodology Ten subjects （6 women,4 men; mean age 25.4 years） participated in the study. The mandibular move-ment,sagittal condylar inclination angle,and transversal condylar inclination angle of each subject were recorded with the CADIAX？ using the two clutches,respectively. The characteristics of the tracings of the protrusion,opening,and mediotrusion were analyzed with the t-test statistics at α = 0.05 level. The Kappa values were calculated for an assessment of the congruence of the tracings. Results The results showed that the contour,direction,and dimension of the tracings in the two clutches were approxi-mately same,but the tracings determined by the functional occlusal clutch were more regular and congruent. In the group segment recorded with the tray clutch,opening/ closing paths of one subject showed crossed and time curves of three subjects appeared peak-like changes of velocity,but none were statistically different （P0.05）. Conclusion The research suggests that the functional occlusal clutch should be preferred in the evaluation of the mandibular function,as the tracings with the tray clutch are more likely to produce false positive results.展开更多
目的:对我国高水平女子体操运动员高低杠项目关节损伤的功能性体能康复训练进行研究。方法:采用问卷调查、专家访谈、测试等研究方法,对11名我国高水平女子体操运动员进行为期12周的功能性训练。采用功能性动作筛查(functional movement...目的:对我国高水平女子体操运动员高低杠项目关节损伤的功能性体能康复训练进行研究。方法:采用问卷调查、专家访谈、测试等研究方法,对11名我国高水平女子体操运动员进行为期12周的功能性训练。采用功能性动作筛查(functional movement screen,FMS)测试评估运动员关节损伤的潜在风险。根据损伤现状调查与评估结果,制定功能性体能康复训练3个阶段的训练目标、任务和方案,提高肩关节灵活性和活动范围,加强肩关节肌肉组织力量,提升运动表现。结果:我国高水平女子体操运动员高低杠项目损伤率最高的部位为肩关节,占比78.18%;高水平女子体操运动员FMS测试损伤风险阈值为17分;功能性训练后肩关节测试均值由1分增加至2分,肩关节疼痛人数由3人下降至1人,总分均值由14分增加至17分。结论:功能性训练前损伤现状调查和FMS测试评估是制定功能性训练方案的依据。FMS测试分数前后具有显著差异,功能性训练能够有效提升肩关节灵活性,改善疼痛现象,促进损伤恢复。展开更多

The development of a standardized food model is presented. Based on the findings of a systematic literature search an elastic food model was created with the aim of standardizing size and elastic properties. Three different eatable jellied products were chosen, created by a changing of the amount of gelatin (260 Blooms) related to the total mass of the standard jellied food. The different hardness were classified in soft, medium and hard, flavored identically, but stained with different colors: soft-green, medium-yellow, hard-red. A cylindrical form was chosen with a height of 1 cm and a diameter of 2 cm. A standard protocol for analyzing chewing patterns in men was created. The condylographic data off several patients are described in details to demonstrate the possible clinical implementation. The newly developed standard food model (SFM) showed the capability to serve in experimental settings to analyze human mastication, although only a few patients have been examined. In addition, strength and size of the newly developed SFM load the masticatory system in an extent;it should be possible to disclose subclinical symptoms of patients within a short time of examination. The diagnostic procedure of temporo-mandibular disorder (TMD) should be endorsed by this new method. The condylographic data created by a standardized protocol should have the ability to enhance the clinical functional analysis of patients previous to restorative dental procedures.展开更多
