Physical demands analysis or a job site analysis is conducted on-site to evaluate the necessary duties that a person has to do on the job, and also the corresponding physical demands that the job places on such an individual.
During the course of the analysis, the individual is interviewed with the supervisor and a scientific assessment of how much the worker can do in his or her job is made.
Based on parameters like physical exertion, postural dynamics, body movement and ability to do jobs of a repetitive nature, a comprehensive report is prepared.
The objective of the physical demands analysis is to nullify or remove any risks that are identified in the course of the investigation.
The physical demands analysis, in other words, is a report that qualitatively shows the physical demands of a particular task. The information is very important for designing a rehabilitation program like work conditioning.
The Physical Demands Analysis of Occupational Tasks in Neighborhood Pubs was a paper published on May 2005 that evaluated physical demands of three common pub occupations-bartending, waitressing and cooking in a pub called British Columbia in Canada.
Physical demand analysis is an objective evaluation of the duties involved in a job that can involve things like repetitive tasks, postures, physical load, forces etc. In a labor intensive job, physical demand analysis assumes a more important role. As you get older, you become more susceptible to injuries that can result in permanent disability. A physical demand analysis can identify risks, and help avoid severe injury.
Depending on the the analysis, a detailed report outlining the physical demands of a particular job, the duties needed to fulfill them, and the corresponding physical efforts needed by workers is provided.
How does the physical demand analysis process work? The therapist performing the physical demands analysis or the job site analysis will set a time to visit the work place, observe the job processes, take measurements of the equipment used, note the methodology involved, and evaluate how easily or strenuously chosen jobs are done.
The therapist will then make recommendations that will reduce injury risk and help ensure the long term health of a worker.

There is nothing really in need of precautions for physical demands analysis since it is a report which evaluates the demands of a certain task and the needed skills and physical attributes for it.
However, it is important that the job site evaluation is accurate and this can be achieved through an honest presentation of the job site during the evaluation of the therapist so that the report is accurate and true.

Top 5 Reasons to consider Physical Demand Analysis
Objective data on the physical demands of a job: The physical demand analysis is a report that states evidently and in transparent terms, the physical demands of a particular job. The report states clearly the pitfalls and risk factors that are associated with a job.
Practical study of a job: The therapist visits the job site, takes note of the equipment being used, observes how the job is completed, and may even do the job to make evaluations. The objective report is greatly useful for the employee, the employer, the doctor and the lawyer of the employee, especially when there is injury or when there is help needed to seek compensation.
Good for designing a rehabilitation program: The physical demand analysis can be useful to design a specific rehabilitation program based on the outcomes of the functional abilities evaluation. Such a program studies how healthy or fit an individual is to do the job. If not, then a customized rehabilitation program based on the physical demand analysis can be prepared.
Good feedback to the employer: The employer can study the job objectively by taking into consideration the findings of the report. He or she can place the employee in a job that best suits the employee or make alterations or modifications in the job.
Lowers injury risk: In labour intensive jobs, there is emphasis on physical strength. As the workforce ages, there is a high risk of disability or injury from the job which can be avoided through physical demand analysis. Newer legislation has stataed that employers must make rational accommodations for people with disabilities on the job.
