摘要:

目的 测量健康和受伤后示指关节活动空间,探讨其在康复中的应用价值。方法 招募示指未受过伤的健康大学生志愿者30例(健康组)和示指近期受伤的大学生志愿者3例(患者组),嘱其在示指独立以及与中指协同状态下做屈伸、内收、外展和环转运动,每个动作重复2次,间隔30 s。采用高清相机记录示指运动轨迹,MATLAB软件整理分析视频,比较两组不同动作的运动范围,绘制伤指运动空间和范围对比图。结果 与健康组相比,患者组示指独立屈伸及内收-外展范围分别缺失26.5%和24.6%。由于伤指恢复程度不同,3例患者环转运动缺陷个体差异较大,最大缺失方向分别在160°、70°和170°。结论 观察示指运动空间缺失范围百分比和最大缺陷方向,有助于对伤指的康复评定。

Abstract:

Objective To measure the space of motion of index finger with and without injury, to apply it in rehabilitation.Methods Thirty healthy undergraduate volunteers (controls) and three undergraduate volunteers with recent index finger injury (patients) were asked to flex, extend, adduct, abduct and ring the index finger independently and combined with middle finger, twice for a motion with an interval of 30 seconds. The index finger movement trajectory was recorded with a high-definition camera, and analyzed the range of flexion, extension, adduction, abduction and ring rotation motion with MATLAB. The movement space and defect of the injured fingers were drawn.Results The ranges of independent flexion-extension and adduction-abduction reduced 26.5% and 24.6% in the patients compared with those of the controls, respectively. The defects of ring rotation space were very different with the degrees of recovery, and the maximum loss happened on 160°, 70° and 170°.Conclusion Loss in index fingers motion space in range and direction may help for rehabilitation assessment.
