Goniometry and photogrammetry are reliable and reproducible methods for evaluating measurements of the hand. However, due to the lack of similar references, detailed studies are needed to define the normal parameters between the methods in the joints of the hand.

Is goniometry reliable and valid?

Pearson product-moment correlation coefficients (r's) and intraclass correlation coefficients (ICCs) were used to analyze the data. The data analysis revealed that the intertester reliability (r = . ... The results of this study indicate that goniometric measurements of the knee joint are both reliable and valid.

What is the most reliable method to measure range of movement?

Results: Compared with the CROM goniometer, the UG aligned on fixed landmarks was the most accurate method, followed by the UG on anatomic landmarks. The reliability of the UG was between substantial and perfect. Visual estimation was reproducible but measured range of movement inaccurately.
