Work related neck and upper limb symptoms have a multi-factorial origin. Possible risk factors are of a physical, psychosocial or personal origin. These factors can reinforce each other and their influence can also be mediated by cultural or societal factors. ⋯ Very few have reported on the preventive effect for work related neck and upper limb symptoms. Therefore, there is a great need for additional high quality trials before any conclusions on effectiveness of bio-behavioural interventions for reduction of neck and upper limb problems and return to work after these symptoms can be made. From the low back pain intervention research can be learned that interventions should best be targeted to both the worker and the organisation and that interventions will only be successful when all stakeholders are involved.

The Pain Disability Questionnaire (PDQ) is a new functional assessment instrument designed for evaluating chronic disabling musculoskeletal disorders. It is useful for assessing function/disability as affected by pain. This is the first study to assess the predictive validity of the PDQ in its relationship to 1-year post-treatment work- and health-related outcomes in a chronic disabling occupational musculoskeletal disorder (CDOMD) population. ⋯ Results demonstrated the ability of this simple and psychometrically-sound disability rating scale for systematic functional assessment in predicting treatment outcomes in patients with CDOMD. Results support the further use of the PDQ as a standard treatment outcomes measure in this area of musculoskeletal disorders.

The present study examined the recovery trajectories of a group of mildly depressed and moderately-severely depressed injured workers enrolled in a 10-week community-based rehabilitation program. ⋯ In order to maximize return to work potential, the content, structure and duration of rehabilitation programs requires modification as a function of the injured workers level of the depression severity.

Quantitative sensory testing has demonstrated a promising link between experimentally determined pain sensitivity and clinical pain. However, previous studies of quantitative sensory testing have not routinely considered the important influence of psychological factors on clinical pain. This study investigated whether measures of thermal pain sensitivity (temporal summation, first pulse response, and tolerance) contributed to clinical pain reports for patients with chronic low back pain, after controlling for depression or fear-avoidance beliefs about work. ⋯ This study supported the neuromatrix theory of pain for patients with CLBP, as cognitive-evaluative factor contributed to pain perception, and cognitive-evaluative and sensory-discriminative factors uniquely contributed to an action program in response to chronic pain. Future research will determine if a predictive model consisting of fear-avoidance beliefs and temporal summation of evoked thermal pain has predictive validity for determining clinical outcome in rehabilitation or vocational settings.

The rate of recurrence in low back pain patients has been reported as high as 70%; therefore, it is believed that researchers have a poor understanding of low back pain recovery. To enhance our understanding of recovery, a large cross-sectional study was conducted to compare outcome measures of return to work, impairment of activities of daily living, pain symptoms, and functional performance probability. A total of 208 workers were examined. ⋯ Single functional performance measures of range of motion, velocity, and acceleration had recovery rates of 59, 13, and 10%, respectively. It appears that all these criteria are measuring very different parameters of low back pain recovery. The residual loss in functional performance may indicate a decreased tolerance to physical demand providing potential insight for why recurrent low back pain rates are high.
