Effect of the post-learning period on the accuracy and self-efficacy of measuring the joint range of motion

Abstract

[Purpose] To verify the effects of the differences in the post-learning period on the accuracy and self-efficacy of measuring the range of passive flexion of the knee and elbow of students. [Participants and Methods] Thirty-six physical therapy students were classified into three groups (short-term, medium-term, and long-term) based on the interval since learning to measure the range of motion. Participants were asked to self-evaluate their efficacy in appropriately measuring the range of motion for knee and elbow flexion using a 10-point Likert scale. Subsequently, the flexion range of the left knee and elbow was measured using a universal goniometer and compared to the measurements obtained using an electronic accelerometer. [Results] Absolute errors in measuring knee flexion were significantly smaller in the medium- and long-term groups than in the short-term group. No other significant main effects or correlations were observed. [Conclusion] Although the accuracy of measuring the range of motion by students improved while they were in school, it did not improve sufficiently based on the joint being assessed. Furthermore, the post-learning period did not affect a student’s self-efficacy for measuring the range of motion and did not reflect its accuracy.
