FULL TITLE: Characteristics and predictors of short-term outcomes in individuals self-selecting yoga or physical therapy for treatment of chronic low back pain.

OBJECTIVE: To compare clinical and demographic characteristics of individuals self-selecting yoga or physical therapy (PT) for treatment of chronic low back pain (cLBP) and to examine predictors of short-term pain and functional outcomes. DESIGN: Descriptive, longitudinal study. SETTINGS: A hospital-based clinic that offers modified integral yoga classes for cLBP and 2 outpatient PT clinics that offer exercise-based PT. PARTICIPANTS: Adults (n=53) with cLBP?12 weeks: yoga (n=27), PT (n=26). METHODS: Yoga participants attended a 6-week, once weekly, 2-hour yoga class. PT participants underwent twice weekly, 1-hour individualized PT. Data were collected at baseline and at 6 weeks. Groups were compared by using ?2 and independent samples t-tests. Hierarchical linear regression was used to predict treatment outcomes. MAIN OUTCOME MEASURES: Disability (Roland Morris Disability Questionnaire), health status (Rand Short Form 36 Health Survey 1.0), pain bothersomeness (numerical rating scale), back pain self-efficacy (Back Pain Self-Efficacy Scale), and treatment satisfaction. RESULTS: At baseline, yoga participants were significantly less disabled (P=.013), had higher health status (P=.023), greater pain self-efficacy (P=.012), and less average pain bothersomeness (P=.001) compared with PT participants. At 6 weeks, when controlling for baseline group differences, greater pain self-efficacy was the strongest predictor for reduced pain and higher function for the entire sample. A significant group interaction by baseline pain self-efficacy predicted disability at 6 weeks. PT participants with low pain self-efficacy reported significantly greater disability than those with high pain self-efficacy. Yoga participants with low and high pain self-efficacy had similar disability outcomes. CONCLUSION: These findings strengthen evidence that self-efficacy is associated with cLBP outcomes, especially in individuals self-selecting PT. Further research to evaluate outcomes after yoga and PT in participants with low pain self-efficacy is needed.

Prostatitis ranges from a straightforward clinical entity in its acute form to a complex, debilitating condition when chronic. It is often a source of frustration for the treating physician and patient. There are four classifications of prostatitis: acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain syndrome, and asymptomatic. Diagnosis of acute and chronic bacterial prostatitis is primarily based on history, physical examination, urine culture, and urine specimen testing pre- and post-prostatic massage. The differential diagnosis of prostatitis includes acute cystitis, benign prostatic hyperplasia, urinary tract stones, bladder cancer, prostatic abscess, enterovesical fistula, and foreign body within the urinary tract. The mainstay of therapy is an antimicrobial regimen. Chronic pelvic pain syndrome is a more challenging entity, in part because its pathology is poorly understood. Diagnosis is often based on exclusion of other urologic conditions (e.g., voiding dysfunction, bladder cancer) in association with its presentation. Commonly used medications include antimicrobials, alpha blockers, and anti-inflammatory agents, but the effectiveness of these agents has not been supported in clinical trials. Small studies provide limited support for the use of nonpharmacologic modalities. Asymptomatic prostatitis is an incidental finding in a patient being evaluated for other urologic problems.
