OBJECTIVE To provide recommendations for the core outcome domains that should be considered by investigators conducting clinical trials of the efficacy and effectiveness of treatments for chronic pain. Development of a core set of outcome domains would facilitate comparison and pooling of data, encourage more complete reporting of outcomes, simplify the(More)
As a way of delineating different levels of cancer pain severity, we explored the relationship between numerical ratings of pain severity and ratings of pain's interference with such functions as activity, mood, and sleep. Interference measures were used as critical variable to grade pain severity. We explored the possibility that pain severity could be(More)
This paper reports the development of a self-report instrument designed to assess pain in cancer and other diseases. It is argued that issues of reliability and validity should be considered for every pain questionnaire. Most research on measures of pain examine reliability to the relative neglect of validity concerns. The Wisconsin Brief Pain Questionnaire(More)
BACKGROUND Radiation therapy is effective in palliating pain from bone metastases. We investigated whether 8 Gy delivered in a single treatment fraction provides pain and narcotic relief that is equivalent to that of the standard treatment course of 30 Gy delivered in 10 treatment fractions over 2 weeks. METHODS A prospective, phase III randomized study(More)
OBJECT The authors report data concerning the safety, effectiveness, and patterns of failure obtained in a Phase I/II study of stereotactic body radiotherapy (SBRT) for spinal metastatic tumors. METHODS Sixty-three cancer patients underwent near-simultaneous computed tomography-guided SBRT. Spinal magnetic resonance imaging was conducted at baseline and(More)
We describe the development of a Chinese version of the Brief Pain Inventory (BPI-C) and demonstrate its reliability and validity. We also report the use of the BPI-C in a three hospital study of cancer pain and its treatment. As with other language versions of the BPI, factor analysis of the BPI-C items results in a two factor solution that satisfies the(More)
This two-phase study was conducted to identify relevant domains of patient-reported outcomes from the perspective of people who experience chronic pain. In Phase 1, focus groups were conducted to generate a pool of patient outcome-related domains and their components. The results of the focus groups identified 19 aspects of their lives that were(More)
Phasic event-related desynchronization (ERD) of alpha activity briefly follows many types of stimulation. In order to define EEG changes resulting from longer stimulation. EEG records were made before and during hand immersion into cool and painfully cold water (cold pressor). Five minutes of 13-lead EEG records were obtained from 14 subjects for each(More)
While many of the multiple symptoms that cancer patients have are due to the disease, it is increasingly recognized that pain, fatigue, sleep disturbance, cognitive dysfunction and affective symptoms are treatment related, and may lead to treatment delays or premature treatment termination. This symptom burden, a subjective counterpart of tumor burden,(More)
OBJECTIVES Patients undergoing major surgery often require several days of postoperative analgesia. However, few data exist on the longitudinal course of postoperative pain and the psychometric properties of pain assessment tools used in this setting. Our objective was to validate use of the modified Brief Pain Inventory through reanalysis of pain data from(More)
