Fear, expectation and back pain - the evidence

Take Home Messages:
Employers can identify workers at increased risk of poor outcomes because of back pain. This can be done by asking about:
- The person’s expectations about their recovery; and
- Fear avoidance beliefs/behaviours.
Understanding a person’s expectations and fears about their back problem – and whether these cause them to avoid activities – can be evaluated through a discussion with the worker.
Why the study matters:
Non-specific low back pain is common. Up to 90% of adults experience low back pain at some stage in their lives. Back pain can prevent a person from working. A small proportion of people do not return to the workforce and this has significant long-term negative consequences: personal, social and economic.
Low back pain costs millions of dollars due to decreased productivity, treatment costs and compensation claims.
Early identification of at-risk individuals is important in lowering the overall burden arising from back pain.
What the study involved:
The authors reviewed relevant research articles on low back pain. A total of 24 studies were analysed.
The research articles examined psychosocial factors affecting failure to return to work. This included:
- Recovery expectations;
- Fear avoidance beliefs/behaviours;
- Depression;
- Stress and anxiety;
- Job satisfaction; and
- Compensation.
Summary of study findings:
Recovery expectation
- Is a strong predictor of return to work.
- Positive recovery expectations were associated with positive health outcomes.
- Realistic expectations of outcome –job/financial security, re-injury, work-place support and self image was associated with earlier return to work.
- Expectations indicate whether psychosocial factors need to be addressed.
Fear avoidance beliefs/behaviours
- Fear of pain can result in avoidance of situations where pain may be induced.
- Pain-related fear leads to increased perceived disability, deconditioning and decreased functional performance.
- Employers should assess fear avoidance beliefs and behaviours early on in treatment.
Factors which do not impact long term disability and failure to return to work are:
- Depression;
- Stress and anxiety;
- Job satisfaction; and
- Compensation.
Employers can identify those who are at increased risk of poor outcomes. This is best done early on in treatment to prevent long term disability.
