Agreement between patients' and health professionals' perceptions has been shown to be low to moderate for different aspects of the patients' pain experience. Little is known, however, about patient-physiotherapist agreement in low back pain. The study objectives were to describe patient-physiotherapist agreement for low back pain intensity and functional limitations, and to identify correlates of agreement. A cross-sectional design was used. Seventy-eight patients with acute/subacute nonspecific low back pain and their respective physiotherapists were included in the study. After the initial physiotherapy consultation, patients and physiotherapists completed a Numerical Rating Scale and the Roland-Morris Disability Questionnaire. Intraclass correlation coefficients (ICC) were used to measure chance-corrected agreement. Patients' and physiotherapists' mean ratings were also compared using paired t tests. Multiple regression analyses were conducted to identify factors associated with agreement measures. The level of agreement was moderate for pain intensity (ICC = 0.55, 95% confidence interval [CI]: 0.38-0.69) and functional limitations (ICC = 0.56, 95% CI: 0.22-0.74). Both variables were rated significantly (P < .05) lower by the physiotherapists than by the patients. Higher ratings by the patients for pain and functional limitations were related to higher differences in perceptions between patients and physiotherapists. This report shows that physiotherapists' perceptions of their patients' pain intensity and functional limitations often differ from their patients'. ⋯ The findings of this study indicate that there are frequent discrepancies between patients' and physiotherapists' perceptions of the patients' low back pain experience. Gaining a better understanding of the level of patient-physiotherapist agreement and identifying the correlates of agreement may help improve physiotherapists' interventions with people with low back pain.

Randomized Controlled Trial Multicenter Study Comparative Study
Psychometric properties of the functional rating index in patients with low back pain.
The purpose of this study was to validate the psychometric properties of the functional rating index (FRI), establish the instrument's minimum clinically important difference (MCID), and compare its psychometric properties with the Oswestry questionnaire. ⋯ The FRI is less reliable than the Oswestry but appears to have comparable validity and responsiveness. Before the FRI can be recommended for widespread use in patients with neck and low back pain, it should be further tested in patients with neck pain.

Severity of vertical impact to the coccyx can range from mere contusion to a dislocated fracture of the coccyx. With early conservative management, most patients have a good prognosis and heal within weeks to months after the initial trauma. Occasionally, persisting symptoms make a surgical intervention with coccygectomy necessary. ⋯ These results suggest that, in patients where all conservative treatment methods work to no avail, particularly those with traumatically induced persisting coccygodynia benefit from surgical intervention with coccygectomy.

Chronic lumbar radicular pain is the most common neuropathic pain syndrome. This was a double-blind, randomized, 2-period crossover trial of topiramate (50 to 400 mg) and diphenhydramine (6.25 to 50 mg) as active placebo to assess the efficacy of topiramate. Each period consisted of a 4-week escalation, a 2-week maintenance at the highest tolerated dose, and a 2-week taper. Main outcome was the mean daily leg pain score on a 0 to 10 scale during the maintenance period. Global pain relief was assessed on a 6-level category scale. In the 29 of 42 patients who completed the study, topiramate reduced leg pain by a mean of 19% (P = .065). Global pain relief scores were significantly better on topiramate (P < .005). Mean doses were topiramate 200 mg and diphenhydramine 40 mg. We concluded that topiramate treatment might reduce chronic sciatica in some patients but causes frequent side effects and dropouts. We would not recommend topiramate unless studies of alternative regimens showed a better therapeutic ratio. ⋯ The anticonvulsant topiramate might reduce chronic lumbar nerve root pain through effects such as blockade of voltage-gated sodium channels and AMPA/kainite glutamate receptors, modulation of voltage-gated calcium channels, and gamma-aminobutyric acid agonist-like effects.

Infective endocarditis in association with spondylodiscitis is rarely observed. It is sometimes difficult to distinguish between rheumatologic diseases and infective endocarditis. We reported a 61-year-old male with Streptococcus viridans endocarditis suffering from low-back pain as initial symptom. ⋯ L4-5 spondylodiscitis was revealed on the lumbar magnetic resonance imaging. He responded to antibiotic treatment. Infective endocarditis should be considered in patients with fever and low-back pain due to spondylodiscitis.
