Validation of the Japanese version of the life satisfaction checklist (LiSat-11) in patients with low back pain: A cross-sectional study.

Background: Previous studies suggest that life satisfaction assessment using the Life Satisfaction checklist (LiSat-11) is a meaningful outcome measure and may play an important role in setting rehabilitation goals in patients with chronic pain. Until now, there was no Japanese version of this questionnaire, and the psychometric properties of the original version of the LiSat-11 have only been investigated using classical test theory approaches. The objective of the present study was to evaluate the psychometric properties of the LiSat-11-J using Rasch analysis in a sample of Japanese people with low back pain (LBP).

Are tactile acuity and clinical symptoms related to differences in perceived body image in patients with chronic nonspecific lower back pain?

Clinically, perceived image of the lower back and the two-point discrimination (TPD) test are used as markers for evaluating alterations of cortical reorganization. The purpose of the present study was to examine whether TPD and selected clinical findings are different in subgroups of individuals with chronic nonspecific lower back pain (CNLBP) based on body image drawings. Forty-two patients with CNLBP and seventeen healthy individuals were recruited.
