The Brief Pain Inventory (BPI) is a highly recommended and frequently used multidimensional pain assessment tool. The BPI includes 2 dimensions: pain intensity and pain's interference with functions. Our aims were to explore how patients respond to pain interference items by comparing responses from patients who had cancer with patients who had noncancer chronic pain (NCCP), and to explore how different levels of health-related quality of life affect upon pain's interference with functions. ⋯ The results indicate that patients are unable to report isolated pain's interference using the BPI. When reporting pain's interference with physical functioning, the level of physical functioning is more important than the level of pain. Patients' diagnoses have to be taken into account when interpreting reported pain's interference with functions.

Spinal cord stimulation (SCS) has been used for almost 40 years to treat refractory neuropathic pain after failed back surgery. Fully implantable non-rechargeable pulse generators have a battery life of between 2 and 5 years. A new SCS system with a rechargeable power source may last 10 to 25 years, or longer. The potential economic implications of longer battery life with a new SCS system has yet to be assessed. The study objective is to estimate the average difference in lifetime costs between rechargeable and non-rechargeable pulse generators used in treatment with SCS for failed back surgery syndrome. ⋯ A rechargeable SCS system is projected to save up to $100,000 over a patient's lifetime. Fewer pulse generator replacements will also decrease patient discomfort and morbidity from procedural complications.

To study the prevalence of upper extremity disorders (UEDs) and neck as a total and complaints of the arm, neck and/or shoulder (CANS) not caused by acute trauma or any systemic disease as defined in the CANS model in the open population and to assess sociodemographic and health characteristics of chronic symptoms. ⋯ UEDs and CANS frequently occur in the open population. Excluding acute traumas and systemic diseases reduced the prevalence of CANS and resulted in a relatively healthier population. A compound definition of CANS seems indicated because of the large overlap of affected anatomic sites.

Randomized Controlled Trial Clinical Trial
Acupuncture for treatment of persistent arm pain due to repetitive use: a randomized controlled clinical trial.
To compare true and sham acupuncture in their abilities to relieve arm pain and improve arm function in individuals with arm pain due to repetitive use. ⋯ Sham acupuncture reduced arm pain more than true acupuncture during treatment, but the difference did not persist after 1 month. Mild side effects from true acupuncture may have blunted any positive treatment effects. Overall, this study did not find evidence to support the effectiveness of true acupuncture in treatment of persistent arm pain due to repetitive use.

The evaluation of tenderness associated with greater trochanteric pain (GTP) syndrome is amenable to bias and depends on the examiner's experience. In this study, we tested whether the use of an electronic pressure algometer enhanced the reliability of this evaluation. ⋯ The examination of tenderness associated with GTP is facilitated by the used algometer. It is the intraindividual body-side PPT differences that yield the most sensitive measurement for the assessment of deep pain. A cut-off value of 0.8 can be used for diagnostic purposes. Interindividual differences might be considerable and could mask pathologic diagnostic findings.
