To evaluate differences in the way iceskaters and roller/inline skaters fall.
Children's falls related to skating were videotaped and categorised based on type of skating activity, child's estimated age, direction of fall, whether the child attempted to break the fall, and whether the head struck the skating surface.
In total, 216 iceskating and 201 roller/inline skating falls were captured on videotape. In both iceskating and roller/inline skating, the majority of falls were forward in direction. The skaters attempted to break the falls with their arms or hands in over 90% of falls in both iceskating (93.1%) and roller/inline skating (94.5%). A greater proportion of falls in iceskating resulted in the head striking the skating surface (13.0%) than did those in roller/inline skating (3.0%) (odds ratio = 4.8; 95% confidence interval 1.9 to 13.3; p<0.001).
This study found that paediatric iceskaters and roller/inline skaters fall similarly and that both types of skaters try to break their falls with their arms or hands; however, because iceskating takes place on a low friction surface, attempts to break falls with the arms or hands are often unsuccessful, leading to head and face injuries. The development of a new type of protective gear, a wrist guard with a non-slip palm, should stop iceskaters from striking the head, protect against upper extremity fractures, and unlike a bulky helmet, should not discourage children from skating.
评估滑冰者与轮滑/直排轮滑者摔倒方式的差异。
拍摄儿童与滑冰相关的摔倒视频，并根据滑冰活动类型、儿童估计年龄、摔倒方向、儿童是否试图缓冲摔倒以及头部是否撞击滑冰表面进行分类。
共拍摄到216次滑冰摔倒和201次轮滑/直排轮滑摔倒的视频。在滑冰和轮滑/直排轮滑中，大多数摔倒方向为向前。在滑冰（93.1%）和轮滑/直排轮滑（94.5%）中，超过90%的摔倒中滑冰者试图用手臂或手缓冲摔倒。与轮滑/直排轮滑（3.0%）相比，滑冰摔倒导致头部撞击滑冰表面的比例更高（13.0%）（优势比=4.8；95%置信区间1.9至13.3；p<0.001）。
本研究发现，儿童滑冰者和轮滑/直排轮滑者摔倒方式相似，且两种类型的滑冰者都试图用手臂或手缓冲摔倒；然而，由于滑冰是在低摩擦表面进行，用手臂或手缓冲摔倒的尝试往往不成功，导致头部和面部受伤。一种新型防护装备——带有防滑手掌的护腕的开发，应能防止滑冰者头部撞击，预防上肢骨折，并且与笨重的头盔不同，不应阻碍儿童滑冰。
