A Physical Demands Analysis (PDA) is a document detailing the essential physical functions a worker must be capable of to successfully and safely perform their job.  Physical demands may include pushing, pulling, lifting, carrying and awkward postures.  The document details the heaviest forces, postures, and positions required and the frequency of each.  The PDA defines frequency as per the US Department of Labor guidelines for occasional, frequent or constant and provides additional details in numbers to further define the physical demands.  The PDA is utilized to assist medical professionals in determining whether workers are ready to return to work after an injury and are vital for performing Job Match Functional Capacity Evaluations (FCEs) or to set up Post Offer of Employment Tests (POET).
