Clerical There are two employees who perform approximately the same task at approximately the same work station configuration.
Information is entered from a hard copy using a computerized work station from a seated position.
There are frequent finger manipulations and long periods of sitting for both employees. ONE also appears to have frequent bending of the head as well as deviation of the wrist. It is difficult to determine the absolute number of repetitions, or period of time that a posture can be maintained or an activity performed, which will cause an injury. But the risk of injury is definitely increased as static posture times or repetitions of a movement are increased. There are sufficient frequencies of finger manipulations often with wrist deviation and prolonged static seating postures to cause musculoskeletal injuries unless adequate engineering and administrative controls are implemented.
