The Polish Version of the Alberta Infant Motor Scale: Cultural Adaptation and Validation

The translation, cultural adaptation, and validation were conducted according to existing recommendations. The motor development of infants was assessed with the Polish scoresheet of the AlMS and the PDMS v.2. The examination was conducted by two peadiatric physiotherapists with a minimum 7 years of experience.The examination methodology was concordant with the recommendation of the authors of AIMS and PDMS-2.The intrarater reliability test included two assessments (with one-month interval) performed by one researcher (Rater A). For the second assessment, the videos of spontaneous motor performance of infants were recorded during the examination. The interrater reliability involved assessments by two researchers (Rater A, Rater B). The Gross Motor Scales of the PDMS v.2 was administered to estimate concurrent validity (participants at the age of 0-12 months).
