Return to Work Interventions for Patients With Low Back Pain

Study Overview
=================
Brief Summary
-----------------
Low back pain has become a major concern to employees and employers because of its negative impact on employee health and productivity. The objective of this study is to investigate whether a return-to-work intervention conducted during inpatient rehabilitation improves functional limitations that are related with low back pain and interfere with job performance.

Detailed Description
-----------------
In recent years most industrialized nations have been confronted with a dramatic increase in cases dealing with back pain; in Germany, back pain belongs to the major individual and societal health problems with associated costs that have put a strain not only on health care systems. Besides frequent demand for medical services, loss of production (due to temporal sick leave) and disability allowances are important economic factors. In total, the estimated annual costs caused by back pain range between 16 and 22 billion Euros. Population based studies revealed high life-time prevalence with 80% report having ever experienced back pain. The point prevalence lies between 30 and 40%. Approximately one-fourth to one-third of those affected suffer from clinically significant back pain. Epidemiological evidence for the prevalence of back pain, its severity, course and associated risk factors is extensive; however, little systematic knowledge is available about treatment of back pain especially about return-to-work interventions. This study is designed as a quasi-experimental study to evaluate benefits of return-to-work interventions during medical rehabilitation. Positive effects are expected for low back pain related functional limitations and subsequently job performance. The intervention tested is based on the biomechanical model of chronic pain that assumes a relationship between external strain, body posture, muscle activity, and intravertebral pressure. According to this model, chronic low back pain is partially caused by overexertion and poor postural habits. The intervention aims at lowering the impact of biomechanical stress by training an adequate body posture while performing activities of daily living or job-related activities. Additionally, performing job-related activities target fear-avoidance beliefs especially assumptions about the connection between pain and work activities. The experimental group training good postural habits while performing activities of daily living or job-related activities (additionally to standard rehabilitation activities such as physiotherapy or education and counselling) will be compared with participants receiving a standard rehabilitation only. Outcome measures are assessed at baseline, post-intervention, and 6 month post-intervention.
