Randomized Controlled Trial Comparative Study Clinical Trial
A randomized controlled trial of intensive neurophysiology education in chronic low back pain.
Cognitive-behavioral pain management programs typically achieve improvements in pain cognitions, disability, and physical performance. However, it is not known whether the neurophysiology education component of such programs contributes to these outcomes. In chronic low back pain patients, we investigated the effect of neurophysiology education on cognitions, disability, and physical performance. ⋯ Education about pain neurophysiology changes pain cognitions and physical performance but is insufficient by itself to obtain a change in perceived disability. The results suggest that pain neurophysiology education, but not back school type education, should be included in a wider pain management approach.

Comparative Study
The utility and validity of the modified brief pain inventory in a multiple-dose postoperative analgesic trial.
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 a multiple-dose, placebo-controlled, randomized trial of analgesia after coronary artery bypass graft surgery. ⋯ The modified Brief Pain Inventory was stable and valid over the assessment period, suggesting that it can be used during the subacute postoperative period to assess postoperative pain among patients with coronary artery bypass graft surgery.

Comparative Study
Prospective diary study of nonpainful and painful phantom sensations in a preselected sample of child and adolescent amputees reporting phantom limbs.
To prospectively study factors associated with the occurrence of phantom sensations and pains in a pre-selected sample of child and adolescent amputees reporting phantom limbs. ⋯ Child and adolescent amputees experience phantom sensations and pains on a regular basis over a 1-month period. Differences in triggers of phantom phenomena between boys and girls may be due to differences in activities, awareness, attribution, and willingness to report psychosocial triggers.

Comparative Study
Reproducibility indices applied to cervical pressure pain threshold measurements in healthy subjects.
To apply various statistical indices for reproducibility analysis of pressure pain threshold measurements and to derive a preferred pressure pain threshold measurement protocol based on these indices. ⋯ The two protocols yielded very similar results. However, on the grounds of patient's comfort and compliance as well as facility of application, protocol B stands out as the more preferred between the two.

Comparative Study
Validity of the brief pain inventory for use in documenting the outcomes of patients with noncancer pain.
The Brief Pain Inventory (BPI) is a short, self-administered questionnaire that was developed for use in cancer patients. While most empirical research with the BPI has been in pain of that etiology, the questionnaire is increasingly evident in published studies of patients with non-cancer pain. The current research addresses the need for formal evaluation of the reliability and validity of the BPI for use in non-cancer pain patients. ⋯ Results support the validity of the BPI as a measure of pain in patients without cancer and, in particular, as a measure of pain for arthritis and LBP patients.
