Toolbox Motor Validation

Five sub-domains of motor function have been identified for inclusion in the NIH Toolbox dexterity, strength, locomotion, endurance, and non-vestibular balance based on literature and expert interviews. Non-vestibular balance efforts have merged with vestibular balance and measures are being led by the balance team within the sensory domain. Candidate measures for each sub-domain have been identified and pre-tested with people across the age spectrum from 3-85. Pre-testing included an evaluation of feasibility, safety, instruction comprehension, ease of administration. During the pilot testing/validating phase of the study, motor function measures will be evaluated to: 1) determine equivalency with criterion measures in each sub-domain 2) ensure that the measures adequately discriminate between people of different skills levels, and 3) minimize floor and ceiling effects.
