Nonspecific back pain is a common complaint, especially among older people. Traditionally, nonspecific back pain has been associated with heavy physical activities. However, static activities such as prolonged sitting and standing are contributing factors to nonspecific lumbar pain as well. Lumbar orthoses, such as belts, have been used for heavy physical activity to alleviate or even prevent back pain; however, studies have been inconclusive as to their effectiveness. Furthermore, the use of lumbar orthosis for prolonged sitting and standing is questionable. This case study and review examines the general effectiveness of lumbar orthosis for a variety of activities, including prolonged standing and sitting. The findings provide implications for orthopaedic nurses in occupational settings.
