Shoulder pain is the second more common musculoskeletal disorder in the primary care setting. Actually, it is estimated that 20% of people will suffer from shoulder pain at some point in their lives. Shoulder disorders may cause pain and/or reduced joint mobility, which necessarily affect quality of life of individuals; and, its influence on productivity and total number of worked hours has a major, well known socio-economic impact.
The Simple Shoulder Test (SST) is a tool designed to evaluate functional limitations of an injured shoulder that compromise an individual’s daily activities. It is a shoulder function scale consisting of 12 items that ask people about their ability to tolerate or perform 12 activities of daily living (ADL). The individual indicates that he or she is able or not to do the activity. The scores range from 0 (worst) to 100 (best) and are reported as the percentage of answered items to which the person responds in the affirmative. It is a practical method for assessment of shoulder function before and after treatment. SST is widely used since the ease of its application has facilitated the comparison of patient outcomes. It is a standardized instrument developed to systematically document shoulder function. SST is also a helpful indicator of the time required to reach a maximum benefit of a treatment for shoulder pain.
