Abstract
|
|
|
Purpose : The purpose of this study was to evaluate inter-tester reliability and Intra-tester reliability about range of motion(ROM) measurement of hip joint with smartphone inclinometer.
Method : Six observers performed goniometric and smartphone inclinometer measurements of various hip movements,
including both active ROM for flexion, extension, external rotation, internal rotation. Measurements were performed in the right hip of fifty normal subjects. All measures were performed three times for evaluating reliability of observer. Inter- and
intra-observer reliabilities were evaluated using the intraclass correlation coefficient(ICC).
Result : The results were as follows, inter-observer reliability ICC value showed .948-.974 in smartphone inclinometer. And
showed .781-.827 in goniometer. Intra-observer reliability ICC value showed .653-.992 in smartphone inclinometer. And
showed .613-.854 in goniometer.
Conclusion : Smartphone inclinometer are portable and widely available tools that are mostly reliable and valid for assessing active hip range of motion, with potential use when a goniometer is not available.
