This study reports on a novel methodology using the V-scope to quantify elbow and shoulder movement in young children with obstetric brachial plexus palsy (OBPP), and the intra- and interreliability of this method. The V-scope, a portable, inexpensive movement analysis system, was configured in an L-shape, with two transmitting towers placed on the floor and one 1.35m off the ground. These towers received ultrasonic pulses from buttons that were placed over standardized landmarks of the child's trunk, chest, and upper limb. Two physiotherapists (a paediatric and a generalist) facilitated the maximum range of active elbow flexion/extension and shoulder abduction/flexion in 30 children with OBPP (18 females, 12 males; age range 6mo-4y 7mo; mean age 2y 6mo [SD 1y 2mo]). Assessments were conducted on two occasions, one week apart. The V-scope was found to be feasible to use by a specialist and a generalist physiotherapist, demonstrating moderate to high reliability coefficients, small measurement errors, and lack of missing data. The pediatric physiotherapist was more reliable in measuring elbow and shoulder movement compared with the generalist physiotherapist, which suggests that the same experienced, pediatric physiotherapist should assess elbow and shoulder movement across all occasions of testing.
本研究报告了一种使用V型视野仪量化产瘫性臂丛神经麻痹（OBPP）幼儿肘部和肩部运动的新方法，以及该方法的内部和外部可靠性。V型视野仪是一种便携式、低成本的运动分析系统，呈L形配置，两个发射塔放置在地面上，一个离地1.35米。这些发射塔接收来自放置在儿童躯干、胸部和上肢标准化标志点上的按钮发出的超声波脉冲。两名物理治疗师（一名儿科物理治疗师和一名普通物理治疗师）辅助30名患有OBPP的儿童（18名女性，12名男性；年龄范围6个月至4岁7个月；平均年龄2岁6个月[标准差1岁2个月]）进行最大范围的主动肘部屈伸和肩部外展/屈曲。评估分两次进行，间隔一周。结果发现，V型视野仪对专科物理治疗师和普通物理治疗师来说都可行，显示出中到高的可靠性系数、小的测量误差且无缺失数据。与普通物理治疗师相比，儿科物理治疗师在测量肘部和肩部运动时更可靠，这表明应由同一位经验丰富的儿科物理治疗师在所有测试场合评估肘部和肩部运动。
