Randomized Controlled Trial Multicenter Study Comparative Study
A randomized trial of chiropractic and medical care for patients with low back pain: eighteen-month follow-up outcomes from the UCLA low back pain study.
Randomized clinical trial. ⋯ Differences in outcomes between medical and chiropractic care without physical therapy or modalities are not clinically meaningful, although chiropractic may result in a greater likelihood of perceived improvement, perhaps reflecting satisfaction or lack of blinding. Physical therapy may be more effective than medical care alone for some patients, while physical modalities appear to have no benefit in chiropractic care.

Multicenter Study
Refinement of the SRS-22 Health-Related Quality of Life questionnaire Function domain.
Prospective observational case series. ⋯ With a minor revision of question 18 (related to going out) the internal consistency of the SRS-22 Function domain has been improved in idiopathic scoliosis patients < 18 years of age. Deletion of question 15 (related to financial considerations) has a variable, small effect depending on patient group. Retention of question 15 is recommended unless a cultural variable, such as differences in healthcare payment schemes, substantially lowers domain psychometric properties.
