To determine the reliability and validity of a pelvic goniometer designed to measure the pelvic tilt and hip flexion during seated posture.
Assessment of the seated posture requires measurement of the pelvis and hip. Determining accurate pelvic tilt and hip flexion angles during sitting is often difficult using standard techniques. A pelvic goniometer has been designed to measure pelvic tilt and hip flexion angle of persons in a seated posture.
VALIDATION of the pelvic goniometer was done radiographically. Ten male volunteers sat in three postures--erect, forward or anterior tilt, and posterior tilt. Pelvic tilt and hip angle were recorded using radiographs and the pelvic goniometer. Reliability of pelvic and conventional goniometers was done using seated nondisabled subjects with physical therapists performing measurements.
the average differences and correlation between the pelvic goniometer and radiographic measures were as follows--pelvic tilt: -4.9 degrees, 0.93; hip angle 1.2 degrees, 0.81. Reliability: average range of hip angle across three measures was about 3 degrees for both goniometers.
The data indicate that the pelvic goniometer has utility in measuring pelvic tilt and hip angle, especially within the seated posture. Because it measures both pelvic tilt and hip angle, the pelvic goniometer has an advantage over conventional goniometers that only measure the latter.
A valid and reliable tool that measures pelvic tilt and hip angle of persons in a seated posture is needed for clinical research and practice. Its applications include wheelchair seating evaluations and ergonomic assessments of seated workers.
确定一种用于测量坐姿时骨盆倾斜度和髋关节屈曲度的骨盆角度计的可靠性和有效性。
坐姿评估需要测量骨盆和髋关节。使用标准技术在坐位时准确测定骨盆倾斜度和髋关节屈曲角度通常很困难。已设计出一种骨盆角度计来测量坐位者的骨盆倾斜度和髋关节屈曲角度。
通过X线摄影对骨盆角度计进行验证。10名男性志愿者以三种姿势就座——直立、前倾或前倾斜以及后倾。使用X线片和骨盆角度计记录骨盆倾斜度和髋关节角度。使用坐位非残疾受试者，由物理治疗师进行测量，以确定骨盆角度计和传统角度计的可靠性。
骨盆角度计与X线测量结果之间的平均差异和相关性如下——骨盆倾斜度：-4.9度，0.93；髋关节角度：1.2度，0.81。可靠性：两种角度计在三次测量中髋关节角度的平均范围约为3度。
数据表明，骨盆角度计在测量骨盆倾斜度和髋关节角度方面具有实用性，尤其是在坐姿状态下。由于它能同时测量骨盆倾斜度和髋关节角度，骨盆角度计比仅测量后者的传统角度计具有优势。
临床研究和实践需要一种有效且可靠的工具来测量坐位者的骨盆倾斜度和髋关节角度。其应用包括轮椅座位评估和对坐位工作者的人体工程学评估。
