Abstract Quantitative measurements of coordination ability were carried out on 76 women with a median age of 37, range 15 to 60. Spacing control, timing control and performance speed were recorded using newly developed computerized equipment, Catsys, presented in this paper. Twenty-three subjects were re-examined 2–3 months after the first measurements. A fair or even high degree of reproducibility of tests was found. Normal values for the entire group and correlation values for the re-examined group are presented. The results from this small study implies that the Catsys may be useful, e.g., in future clinical neurological practice of diagnostics and follow up on patients, in occupational medicine for detection of neurotoxic effects of various neurotoxic substances, in evaluation of drug effects and side effects and for testing people in occupations where normal coordination skills are absolutely necessary.
