Job accommodation in muscle strength.
Muscle Strength. Kumar, S ed., Boca Raton, FL: CRC Press, 2004 Apr; :469-483
At the most fundamental level, the process of job accommodation deals with the relationship between the physical demands of the task and the capabilities of the worker. This can be thought of as the "fit" between the human and his or her work environment. A poor fit can cause unnecessary stress and can result in traumatic or cumulative injuries/ illnesses. This fit may be pictured as the overlap between the capabilities of the individual and the requirements of the task as shown in Figure 20.1. When the capabilities of the individual equal or exceed the physical demands of the task, the stresses tend to be low. When the capabilities of the individual are exceeded by the physical demands of the task, the stresses increase. This chapter deals with (a) methods to quantify the physical demands of essential job functions, (b) methods to estimate the capability of the individual to accomplish these demands, (c) the regulatory framework within which these issues must be addressed, and (d) use of contemporary ergonomic analysis tools to evaluate and optimize the "fit" between the worker and the job.
