Comparative Study
Confirmatory factor analysis of the Pain Catastrophizing Scale in African American and Caucasian Workers' Compensation claimants with low back injuries.
Pain catastrophizing is an important cognitive construct that has been linked with many aspects of the pain experience, including pain intensity, emotional distress, pain-related disability, and pain behavior. The Pain Catastrophizing Scale (PCS), an instrument often used to assess this construct, reflects three aspects of catastrophizing: Rumination, Magnification, and Helplessness. ⋯ Results indicated that a two-factor model of the PCS (Rumination and 'Powerlessness,' the latter a combination of the PCS Magnification and Helplessness scores) was the most parsimonious fit to the data, particularly in the African American sample. Future research in other clinical samples that include African Americans is needed to examine the stability of the results reported here.

Comparative StudyRadiofrequency heating of painful annular disruptions: one-year outcomes.
Although several studies have reported on outcomes following heating of annular tears with a thermoresistive catheter (SpineCATH), no data are available on the efficacy of thermal treatment with a flexible radiofrequency electrode (discTRODE). A prospective case-control study was conducted to determine the efficacy of radiofrequency heating of painful annular tears in the lumbar spine. ⋯ Radiofrequency heating of annular tears can lead to an improvement in the pain of internal disc disruption. The improvement gained by this treatment method is significantly better than that obtained from conservative management.

A prospective clinical and radiologic investigation of two groups of patients presenting with either acute back pain only or acute leg pain only, yet similar restriction in straight leg raising (SLR). ⋯ Acute low back pain associated with significant restriction in SLR is likely to be caused by a disc prolapse compressing the anterior theca.

[The Oswestry index for low back pain translated into Arabic and validated in a Arab population].
To translate into Arabic and validate the Oswestry index for low back pain in an Arab population. ⋯ We translated into and adapted the Oswestry index for the Arabic language in a population of Tunisian women? with low back pain. The 8-item version is reliable and valid. Although the scale was validated in a Tunisian population, we expect that it is suitable for other Arab populations, especially North Africans. Further study is needed to confirm such a hypothesis.
