Motor co-ordination is an important prerequisite to adequate upper-extremity performance. With the ageing of the population, more and more elderly people are at risk of acquiring upper-extremity motor inco-ordination following sensorimotor deficit. The main objective of the study was to develop normative data on upper-extremity motor co-ordination for elderly people. Three hundred and sixty subjects aged 60 and over were randomly selected and evaluated with the Finger-Nose Test. The results revealed a linear decline in the performance of this test with age. Younger, more active and subjectively healthier subjects presented better motor co-ordination. Some differences were found between sexes and sides. The normative data will help clinicians to identify pathological reduction in motor co-ordination in an elderly population.
