Medium work is one of the five job classifications used by the SSA to determine if you are able to continue to perform work of any kind. The SSA will determine your level of maximum sustained work capability by reviewing your medical records and the questionnaires completed during the claims application process. It is important to be detailed about your condition as the SSA will only consider ailments and restrictions present in your medical records. If they determine that you are able to perform medium work it is unlikely that your disability application will be approved.
Medium work is defined as being able to lift up to 50 pounds at once and lift up to 25 pounds on a consistent basis and be able to stand and walk 6 hours per 8-hour shift. If you are able to perform medium work you are considered able to perform occupations in each both light and sedentary work as well.
