[The motormetric Rostock-Oseretzky scale]

A new motometric scale with 24 tasks was designed taking into account Oseretzky tasks. It was standardized with 325 normal school children ranging in age from 5 to 11 years. The normal presentation in form of C scales and MQ scales, resp., allows a qualitative evaluation of the motor development irrespective of the age of the child. Furthermore, the procedure allows an improvement in the successful diagnosis of cerebral lesions in early infancy; this was verified by an examination of 92 children with proved brain lesions or high risk births. Details are given on the reliability, validity with reference to criteria, and diagnostic value of the scale. The procedure is economic as far as the necessary time is concerned and therefore it can also be applied in the treatment of out-patients.
