The Commission for Motion Laboratory Accreditation, Inc. (CMLA) is a nonprofit organization established and operated to enhance the clinical care of persons with disorders of human movement by evaluating and accrediting clinical motion laboratories by a set of evaluative criteria.


By the year 2020, all clinical motion laboratories in the United States will have achieved full accreditation from CMLA.

What is Motion Analysis?

Motion analysis is a standard diagnostic laboratory procedure present in many clinical facilities which treat patients with gait dysfunction or of other disorders of human movement. These laboratories evaluate individuals with the goal of quantifying their movement disorder and determining the specific anatomic, physiologic, or functional causes of their movement pattern. The information can then be used to assist in planning the treatment approach.

Common medical conditions which are evaluated include cerebral palsy, residual disabilities due to strokes, neurologic disabilities that cause motor control problems, severe musculoskeletal abnormalities, and amputations. The testing typically involves a detailed physical examination, and measurement of multiple joint motions, mechanical forces at multiple joints, and electrical activity in multiple muscles collected while the person is walking or making the affected motion. Video recording, measurement of foot pressure and measurement of the energy cost of walking are also common aspects of this evaluation if needed to describe the movement problem.

About the Commission

CMLA was incorporated in Delaware in 1997. In 2010 CMLA became a tax exempt, non-profit organization by the authority of the Internal Revenue Service and the State of Delaware under section 501 (c) (3) of the Federal tax code. The Board of Directors is comprised of professionals from several disciplines with expertise in clinical motion analysis, and includes two Directors from each of the four member societies:

These eight Directors appoint an additional four individuals "at large" to serve on the Board of Directors. The Board of Directors sets the standards, oversees the review process, and makes the final determination of approval of the laboratory application for accreditation
