Goniometry of the proximal and distal interphalangeal joints, Part II: placement prefereces, interrater reliability, and concurrent validity.
The purposes of this repeated-measures single-case-design study were to describe goniometric placement preferences and their effect on the measurement of the proximal and distal interphalangeal joints, to determine interrater reliability, and to determine concurrent validity. Thirty-nine therapists measured one patient dorsally and laterally with the DeVore and the 6" clear goniometers. No significant differences were found between the two goniometers used in the study. Comparison of the means of lateral and dorsal measurements revealed that the only joint associated with a significant difference was the contracted index proximal interphalangeal joint (p=0.0347). Preferences did affect the standard deviations and ranges but not the means of the measurements. Interrater reliability was high (ICC 2,1: 0.99 and 0.86). Clinical and radiographic measurements were markedly different from each other (paired-difference t-tests), leading to inconclusive concurrent validity.
