Randomized Controlled Trial Clinical TrialBotulinum toxin type B in upper-limb poststroke spasticity: a double-blind, placebo-controlled trial.
To determine whether botulinum toxin type B (BTX-B) is effective in controlling upper-limb spasticity. ⋯ Our study does not show a significant decrease in tone from 10000 U of BTX-B. Dry mouth was common.

Randomized Controlled Trial Clinical TrialHigh-power pain threshold ultrasound technique in the treatment of active myofascial trigger points: a randomized, double-blind, case-control study.
To study what effects a high-power, pain-threshold, static ultrasound technique applied to acute myofascial trigger points of the upper trapezius has on pain and on active cervical lateral bending. ⋯ High-power, pain-threshold, static ultrasound technique may be considered in the treatment of patients with acute myofascial pain syndrome, with the understanding that this technique demands more concentration and communication between the patient and the therapist.

Analysis of outcome measures for persons with patellofemoral pain: which are reliable and valid?
To examine the test-retest reliability, validity, and responsiveness of several outcome measures in the treatment of patellofemoral pain. ⋯ The AKPS and VAS for usual or worst pain are reliable, valid, and responsive and are therefore recommended for future clinical trials or clinical practice in assessing treatment outcome in persons with patellofemoral pain.

Assessing pain in patients with severe cerebral palsy: development, reliability, and validity of a pain assessment instrument for cerebral palsy.
To develop the Pain Assessment Instrument for Cerebral Palsy (PAICP) and to study its test-retest reproducibility and construct validity. ⋯ The PAICP has adequate test-retest reproducibility and construct validity. It provides an indication of the pain experienced by patients in situations in which proxies are not personally involved and may also be more valid than proxy measures for other situations.

Comparative StudySitting and standing tolerance in patients with chronic back pain: comparison between physician prediction and covert observation.
To measure covertly observed continuous sitting and standing tolerance in patients with chronic back pain and to compare observations to physician predictions. ⋯ The majority of this sample demonstrated the ability to sit continuously 60 minutes or more and to stand continuously 30 minutes or more while being covertly observed. Expert physician prediction showed poor correlation to covertly observed sitting and standing tolerances, raising doubt about the validity of using physician evaluation to establish work restrictions in patients with chronic back pain. These findings are preliminary, follow only a brief period of covert observation, and indicate the need for further research in this area.
