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.

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.

The objective of this systematic review was to assess the effectiveness of guided imagery (GI) as a treatment option for musculoskeletal pain (MSP). ⋯ It is concluded that there are too few rigorous RCTs testing the effectiveness of GI in the management of MSP. Therefore, the evidence that GI alleviates MSP is encouraging but inconclusive.

The aim of the present study was to describe fear-avoidance beliefs, catastrophizing, and emotional distress among musculoskeletal pain patients in primary healthcare and to explore the relationship of psychological risk profiles for pain, function, and sick leave from baseline through 1-year and 3-year follow-ups. ⋯ Distinct profiles of catastrophizing, fear-avoidance beliefs, and emotional distress were extracted and meaningfully related to future sick leave and dysfunction outcomes. The structures of the profiles were essentially stable and became more accentuated across a 3-year period. The results underscore the need to address psychological aspects as fear-avoidance beliefs, catastrophizing, and emotional distress in the management of patients with musculoskeletal pain and may open the path for a better tailored treatment approach for this patient group.

To determine the hypoalgesic effects of transcutaneous electrical nerve stimulation (TENS) parameter combinations on experimental models in healthy humans. ⋯ The level of hypoalgesic efficacy of TENS is clearly dependent on TENS parameter combination selection (defined in terms of intensity, frequency, and stimulation site) and experimental pain model. Future clinical RCTs may consider these TENS dose responses.
