Definition - What does Critical Strength and Mobility Testing mean?

Critical strength and mobility testing (CSM) is a baseline test used to assess the overall strength and endurance to handle a job by controlled movements and postures at timed intervals. An employer will use a CSM to chart tasks played up to the caliber of performance a job candidate must meet based on the line of work involved.

SureHire explains Critical Strength and Mobility Testing

CSM tests will evaluate the overall strength, conditioning, and stamina to satisfy the job requirements that may tax the body. A physical demands analysis (PDA) is an index that compares gross motor skills to the normative range values to perform a job with sustained effort. SureHire conducts a range of CSM tests in our comprehensive Fitness-to-Work testing program. This includes: floor-to-waist lifts, 10 and 20 ft. carry, long carries, one-hand carries, overhead lifting, and step tests. The load-displacement of objects between set points helps to show how well a person can make neutral transfers that occur on the job.


Critical strength and mobility testing reviews give an employer the objective data they need to ensure they hire the best candidate where physical demands are consistent with the job role. Body mechanics and locomotion are good markers to see if a job prospect is a right fit based on a limited or impaired function that might affect their job performance. In some cases, a work accommodation dovetails off the ability of a worker to meet the job demands.
