To evaluate the intra-rater repeatability and the inter-rater reproducibility of using a virtual goniometer to measure upper and lower extremity joint range of motion (ROM) in youths with arthrogryposis multiplex congenita (AMC).
Youths presenting with AMC aged 8 to 21 years old were recruited. ROM of the upper and lower limbs were assessed remotely during a teleassessment on a video-conferencing platform. Screen captures were taken and ROM were measured by two raters, two-weeks apart, using a virtual goniometer. Intraclass correlation coefficient (ICC) and associated 95% confidence interval (CI) were calculated to assess intra-and inter-rater repeatability and reproducibility.
Nine participants were included with a median age of 15.9 years (range: 11.3 to 20.8 years). The overall intra-rater ICC was 0.997 (95% CI:0.996 to 0.997) for the first rater and 0.993 (95% CI:0.992 to 0.994) for the second rater. The inter-rater ICC ranged from 0.410 (95% CI:-0.392; 0.753) for forearm pronation to 0.998 (95% CI:0.996; 0.999) for elbow flexion.
Results of the current study suggest that virtual goniometry is reproducible and repeatable for the ROM of most joints. Future studies should evaluate procedural reliability and validity of the proposed method for youth with complex conditions.
评估使用虚拟量角器测量多发性先天性关节挛缩症（AMC）青少年上肢和下肢关节活动度（ROM）的内部和外部再现性。
招募了患有 AMC 的 8 至 21 岁的青少年。在视频会议平台上的远程远程评估中，评估了四肢的 ROM。拍摄屏幕截图，由两名评估员在两周后使用虚拟量角器进行两次评估，以测量 ROM。计算了组内相关系数（ICC）和相关的 95％置信区间（CI），以评估内部和外部评估员的可重复性和再现性。
共纳入 9 名参与者，中位年龄为 15.9 岁（范围：11.3 至 20.8 岁）。第一次评估的总体内部评估员 ICC 为 0.997（95％CI：0.996 至 0.997），第二次评估的 ICC 为 0.993（95％CI：0.992 至 0.994）。两次评估员之间的 ICC 范围从 0.410（95％CI：-0.392；0.753）的前臂旋前到 0.998（95％CI：0.996；0.999）的肘弯曲。
当前研究的结果表明，虚拟量角器对于大多数关节的 ROM 具有可重复性和可再现性。未来的研究应评估该方法对患有复杂疾病的青少年的程序可靠性和有效性。
