CONCLUSION
Various procedures and instruments have been described in the literature for quantifying PST, thus it is difficult to state that the method described and investigated in this paper is superior to others.
This investigation presents a reproducible and valid measurement protocol for quantifying PST using an inclinometer.
The inclinometric procedure outlined in this investigation had a reliability coefficient of 0.90 which is the threshold recommended for tests to be useful in making clinical decisions and is a suitable alternative to linear measurements as it
allows for intersubject comparison.
Clinicians and researchers should consider the MDC values presented (9°) when interpreting change values during
subsequent measurement sessions to be certain that the change is not due to intertrial variability or measurement
error.
