Evaluation of Assessments of Motor Performance, Physical Impairments and Functional Abilities

Objective The objective of the protocol is to provide framework in which clinicians in the Department of Rehabilitation Medicine (RMD) can serve the clinical needs of patients and the intramural clinical research needs of NIH investigators by maintaining state of the art expertise in the functional assessment of persons with disabilities and investigating new equipment, methodologies and/or techniques for functional assessment. Study Population We intend to study a total of 500 healthy volunteers and 500 subjects with disabilities, including those enrolled in NIH intramural research protocols. Design The study will consist of individual projects designed designed by RMD staff including one or more of the associate investigators. The individual projects will be relatively small and designed to test the reliability, reproducibility, efficiency, feasibility, sensitivity, specificity, tolerability, validity and/or precision of physical medicine and rehabilitation assessment equipment, devices and clinical evaluations of impairment, disability, and/or function. Outcome Measures The specific outcome measure(s) will be chosen to meet the goals of the individual project and will generally include one or more of the following: i. Subjective assessment by the participant of the test, device, or evaluation based on written evaluation tools. ii. Comparisons to established evaluations or equipment designed to assess similar areas of function, including concurrent validity analyses. iii. Subjective assessment by clinicians using the test, device or evaluation, based on written evaluation tools. iv. Feasibility assessments, including the time required for participants to perform tests, time for clinicians to evaluate the results of the tests, and/or prepare reports of the results of tests. v. Assessments of reliability and/or stability of the technique used, including statistical tests of coefficients of variability. vi. Assessments of tolerance of tests, including measures such as vital signs or elements of a physical examination.
