目的:研究我国成年男子头颈部前屈运动特征,其中包括头部质心轨迹与前屈角度。方法:根据中国成年人人体尺寸国家标准GB10000-88,选取5/50/95三个百分位志愿者各10例;受试时,志愿者躯干保持不动,头颈部在矢状面内自然前屈;使用Raptor-4... 目的:研究我国成年男子头颈部前屈运动特征,其中包括头部质心轨迹与前屈角度。方法:根据中国成年人人体尺寸国家标准GB10000-88,选取5/50/95三个百分位志愿者各10例;受试时,志愿者躯干保持不动,头颈部在矢状面内自然前屈;使用Raptor-4运动捕捉系统捕捉志愿者身上所贴标志点的坐标,通过对标志点坐标计算得出头部质心与转动角度。结果:(1)获得了5/50/95百分位成年男子头颈部前屈运动特征,运动特征数据与志愿者身高成正相关;(2)将运动特征数据取综合均值作为装置设计基准,3个百分位数据相对于综合均值的误差最大为10.08%。结论:通过头颈部前屈运动特征研究,可为颈部康复或防护装置设计提供边界条件。 展开更多

Objective: Interphalangeal joint con- tracture is a challenging complication of hand trauma, which reduces the functional capacity of the entire hand. In this study we evaluated the results of soft tissue distraction with no collateral ligament transection or volar plate removal in comparison with traditional operation of contracture re- lease and partial ligament transection and volar plate removal. Methods: In this prospective study, a total of 40 pa- tients in two equal groups (A and B) were studied. Patients suffering from chronic flexion contracture of abrasive trau- matic nature were included. Group A were treated by soft tissue distraction using pentagonal frame technique and in Group B the contracture release was followed by finger splinting. Results: Analyzed data revealed a significant differ- ence between the two groups for range of motion in the proximal interphalangeal joints (P〈0.05), while it was not meaningful in the distal interphalangeal joints (P〉0.05). There was not a significant difference in the degrees of flexion contracture between groups (P〉0.05). Regression analysis showed that using pentagonal frame technique significantly increased the mean improvement in range of motion of proxi- mal interphalangeal joints (P〈0.001), while the higher the preoperative flexion contracture was observed in proximal interphalangeal joints, the lower improvement was achieved in range of motion of proximal interphalangeal joints after intervention (P〈0.001). Conclusion: Soft tissue distraction using pentagonal frame technique with gradual and continuous collateral liga- ment and surrounding joint tissues distraction combined with skin Z-plasty significantly improves the range of mo- tion in patients with chronic traumatic flexion deformity of proximal and/or distal interphalangeal joints. 展开更多
