Even so, Perkins et al. (2004) reported the MM3B had extremely high single and multiple trial reliabilities and with narrow confidence intervals.
While this technique demonstrates radiographic validity and high test-retest reliability, it is yet to be assessed with regards to inter-tester and trial-to-trial reliability.
We demonstrate that this mechanism explains major neurophysiological hallmarks of selective attention, including multiplicative neural gain, increased inter-trial reliability (decreased variability), and reduced noise correlations.
The trial-to-trial reliability ICC (2,1) coefficient was 0.96 with an SEM of 2.05 Nm/rad, and the day-to-day reliability ICC (2,k) coefficient was 0.93 and an SEM of 3.00 Nm/rad.
A single-group repeated measure design using 4 testers was conducted to evaluate the inter-tester and trial-to-trial reliability of palpation digitization technique for innominate vector length measurements using the Polhemus electromagnetic tracking device.
Reliability indexes of Intraclass correlation coefficient (ICC) (≥0.97) and Standard error of measurement (SEM) (≤2.02 mm) demonstrated very high inter-tester and trial-to-trial reliability and accuracy of palpation digitization technique for innominate vector length measurements, irrespective of the two test positions.
The values measured between trials (reliability and criteria-related validity).
Inter-trial reliability within this study for leg°max during the iSLR was high (ICC r = 0.98).
Inter-trial reliability (from three trials for each subject) for all LLx, ULx and TLx repeated measures in this study were excellent.
LLx (L3-S2), ULx (T12-L3), and total lumbar (TLx) angles (T12-S2) were calculated, as previously defined (see Figure 2) and shown to possess excellent inter-trial reliability in sitting [ 6].
Between-trial reliability for VAS scores reported during the manual SLR tests to establish maximum range of motion (performed prior to the recorded iSLR) had an ICC r-value > 0.95.
