The link between chronic back pain and disability is well established. Despite this, the literature also reflects an inconsistency in methods of assessing disability, as studies interchangeably use self-report measures, clinical tests, and electronic monitoring. The purpose of this study was to conduct a multimethod comparison of disability measures to identify similarities and differences in the constructs measured by each. ⋯ The results indicate substantial differences in the types of variables that predict disability when measured through 3 different methods. This is suggestive of differences in the constructs measured by each type of disability assessment. The implications for researchers who assess predictors of disability and clinicians who use disability measures in their assessment of patients are that the measures of disability they select should be carefully matched to the proposed purposes. Strong theoretical and practical considerations support using electronic ambulatory monitoring in future research and clinical service.

Phantom limb perception is common following amputation, and is sometimes characterised by pain that resembles the characteristics, intensity or location of past pain. We tested Flor's model that phantom pain results from memory for long-lasting znoxious input. ⋯ We propose that somatosensory pain memories likely relate to the generation and maintenance of limb representations upon which intense or emotionally powerful past experiences have been imprinted.

To identify predictive factors requiring high-dose transdermal fentanyl in opioid switching from oral morphine or oxycodone to transdermal fentanyl in patients with cancer pain. ⋯ Our study indicates that breast cancer, total protein, alanine aminotransferase, advanced age, and male sex are significant predictors of a need for higher dose transdermal fentanyl in opioid switching. Our results are considered likely to contribute to the establishment of evidence-based medicine in pain relief and palliative care.

Randomized Controlled Trial Comparative Study
Comparing the effectiveness of mindfulness-based stress reduction and multidisciplinary intervention programs for chronic pain: a randomized comparative trial.
Research suggests that an 8-week Mindfulness-Based Stress Reduction (MBSR) program (a structured form of meditation) might be effective in the treatment of various health problems including chronic pain. Our objective was to compare the clinical effectiveness of the MBSR program with a multidisciplinary pain intervention (MPI) program in terms of pain intensity, pain-related distress, quality of life, and mood in patients with chronic pain. ⋯ This randomized, clinical trial showed that both MBSR and MPI programs reduced pain intensity and pain-related distress although no statistically significant differences were observed between the 2 groups and the improvements were small.

The primary goal of this study was to investigate the incidence of chronic pain 1 year after a thoracotomy. Secondary goals were to determine which interventions and patient characteristics were associated with reports of chronic pain, to identify risk factors, to clarify the neuropathic component, and to determine the impact of chronic pain on daily life. ⋯ Chronic pain is common after thoracotomy and its neuropathic component is infrequent. As age, ASA scores, number of drains, and situations relating to daily life seem to play a role in pain occurrence, a multifaceted approach against the onset of chronic pain is advisable.
