Repetitive Stress Inury

WebMD Feature

Feb. 21, 2000 (Washington) -- The meat cutter's shoulder may hurt from cutting chickens and the autoworker' s back may ache from hanging doors on Chevrolets, but are those injuries covered under the Occupational Safety and Health Administrations's new ergonomic rules?

The proposed guidelines define a musculoskeletal disorder as an "injury or disorder of the muscles, tendons, ligaments, joints, cartilage, and spinal discs." Signs of an injury include decreased grip strength or range of motion, or deformity or loss of function.

Visiting the ER for Chronic Pain

You’re a chronic pain patient who takes several prescription narcotics to control your symptoms. Then one weekend, excruciating pain lands you in the emergency room. There, a doctor grills you about your medications, in part to make sure that you’re a legitimate pain patient, not someone seeking drugs. What can you do to help the ER doctor to believe you?

For upper extremity injuries like carpal tunnel syndrome, symptoms include numbness, tingling, pain, burning, and cramping in the arms, fingers, or hands. To be covered under the OSHA guidelines, an injury must be diagnosed by a health care professional. It also has to be serious enough to require medical treatment and to require that the employee spend one or more days away from work or be assigned to a less strenuous job.

The condition also needs to be directly related to the employee's job. For example, a warehouse worker's back injury would likely be covered, but his carpal tunnel syndrome probably would not, unless a lot of his job involves entering inventory information into a computer. An injury must also involve a worker's "core" duties: If a poultry processor hurts her back because she routinely changes the water bottle in the break room, the ergonomics requirements would not apply.
