Use of a text of psychomotor ability in an expanded role.

To examine the use of a test of psychomotor ability of disabled persons, a group of 118 persons with permanent impairment of one hand were given the disability rating together with the O'Connor Finger Dexterity Test. Scores showed a substantial correlation of .69 between these two instruments. Scores on the Finger Dexterity Test were strongly correlated to the activities of daily living subscale of the Hand Disability Rating Scale (.88), while rating of disability was not. Age appeared unrelated to either test or disability scores.
