Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Economic evaluation of a behavioral-graded activity program compared to physical therapy for patients following lumbar disc surgery.
An economic evaluation was conducted alongside a randomized controlled trial. ⋯ This study concludes that there are no differences between the two treatment conditions on any of the clinical outcome measures but that behavioral-graded activity is associated with higher costs. Consequently, there is no reason for the implementation of behavioral-graded activity as the standard treatment for patients following lumbar disc surgery.

Multicenter Study Comparative Study
A low back-specific version of the SF-36 Physical Functioning scale.
A prospective repeated measures design was used to produce a back-specific version of the Short Form-36 Physical Functioning scale (SF-36 PF) by Rasch analysis of a pool of items from the SF-36 PF, Oswestry Disability Questionnaire, and the Quebec Back Pain Disability Scale. ⋯ The Low-Back SF-36 PF18 comprises the 10-item SF-36 PF scale and four items each from the Oswestry and Quebec back pain questionnaires. The possible total score ranges from 0 to 100, with a higher score indicating better function. The new scale appears to offer advantages over the use of the original scale for the assessment of functioning in patients with low back pain.
