不同检查者和不同检查工具对关节活动度检查的影响

目的观察不同检查者和不同检查工具对关节活动度(ROM)检查的影响。方法对104名健康青年人进行肩前屈、后伸、外展、内旋、外旋ROM测定,每位受试者接受2位检查者用通用量角器和方盘量角器检查,对比受试者主动活动与被动活动、左侧与右侧、同一检查者用通用量角器与方盘量角器的ROM值,以及不同检查者用通用量角器、方盘量角器的ROM值。结果无论用哪一种量角器,受试者主动ROM均小于被动ROM,有显著差异,但左右两侧ROM无显著差异。使用通用量角器和方盘量角器相比,肩前屈ROM无显著差异,肩后伸、外展、内旋、外旋ROM有显著差异。不同检查者用方盘量角器测量ROM值无显著差异,用通用量角器测量肩内旋ROM值无显著差异,肩前屈、后伸、内旋、外旋ROM值有显著差异。结论方盘量角器测量ROM的可重复性较高。为确保ROM检查结果的可比性,应由同一位检查者使用同一种检查工具对患者进行ROM检查。

Influence of examiners and goniometers on measurement of range of motion

Objective To difine the influence of examiners and goniometers on measurement of ra nge of motion(ROM).Method We evaluated 104normal youngers in fle xion,extension,abduction,intern al rotation and external rotation RO M value of the shoulder.Each subject was examined by two examiners and two goniometers,including uni versal goniometer and gravity-acti vated goniometer.Result ROM measured by active motion was less th an passive motion.There was no signi ficant difference of ROM between left and right.However,singnificant difference was found i n extension,abduction,internal ro tation and external rotation betwee n two goniometers,except flexion.Inter-observer discrepancy was not significant in ROM of all dimension w ith gravity-activated goniometer a nd in internal rotation ROM with universal goniometer ,but signific ant in flexion,extension,abductio n and external rotation ROM .Conclusion The consistency of gravi-ty-activated goniometer was better than universal goniometer.
