| Abstract: | Purpose] To investigate whether an objective evaluation method for trunk function,
namely the “trunk righting test”, is reproducible and reliable by testing on different
observers (from experienced to beginners) and by confirming the test-retest reliability.
Subjects] Five healthy subjects were evaluated in this correlation study. Methods] A
handheld dynamometer was used in the assessments. The motor task was a trunk righting
motion by moving the part with the sensor pad 10 cm outward from the original position.
During measurement, the posture was held at maximum effort for 5 s. Measurement was
repeated three times. Interexaminer reproducibility was examined in two physical
therapists with 1 year experience and one physical therapist with 7 years of experience.
The measured values were evaluated for reliability by using intraclass correlation
coefficients (ICC 1.1) and interclass correlation coefficients (ICC 2.1). Results] The
test-retest reliability ICC 1.1 and ICC 2.1 were all high. The ICC 1.1 was >0.90. The
ICC 2.1 was 0.93. Conclusion] We developed the trunk righting test as a novel objective
evaluation method for trunk function. As the study included inexperienced therapists, the
results suggest that the trunk righting test could be used in the clinic, independent of
the experience of the therapists.Key words: Trunk function, Reliability, Handheld dynamometer |
