Thirty-three licensed physical therapists served as subjects in this study utilizing the single inclinometer method for measuring active cervical range of motion before and after the presentation of an inservice. Paired t-tests were used to determine mean differences in measurement for each motion before and after the inservice. The t-test values reported that there was a significant difference found in the measurements of right rotation and left rotation yielding mean values of 78.71± 6.62 degrees and 82.74 ± 6.78 degrees, respectively. There was no significant difference found in flexion, extension, and lateral flexion between the pre and post test conditions. The ICC (3,1) values indicated good intratrial reliability in the pre-test measurements for all motions except right lateral flexion (0.78). Good reliability was also reported in the post-test condition for extension, left. rotation and right rotation yielding values of 0.86, 0.92, and 0.90, respectively. Flexion/extension, right lateral flexion and left lateral flexion demonstrated poor intratrial reliability in the post-test condition, yielding values of .67, .62, and .78, respectively. Comparisons of radiographs and CT scans demonstrated inconclusive validity results. Based on the findings of the study, suggestions were made to further investigate reliability and validity of inclinometer measurements.
