Intra-observer reliability of Prechtl’s method for the qualitative assessment of general movements in Taiwanese infants

[Purpose] The aim of this study was to examine the intra-observer reliability for Prechtl’s General Movements Assessment in Taiwanese infants. This includes the global General Movements Assessment, the Optimality List for Preterm General Movements and Writhing Movements, and the Assessment of Motor Repertoire—3 to 5 Months. [Subjects and Methods] Fifty-nine videos of 37 infants were observed and rated by one physical therapist twice. [Results] The intra-observer reliability ranged from good to very good for the global General Movements Assessment. The overall intra-observer reliabilities for the total score of the Optimality List from preterm up to postmenstrual age 46 weeks and the total score of the Assessment of Motor Repertoire for postmenstrual age 49 to 60 weeks were both good. [Conclusion] The results suggest that the intra-observer reliability of a certified physical therapist was satisfactory for Prechtl’s method in Taiwanese infants.
