A randomized controlled component analysis of a behavioral medicine rehabilitation program for chronic spinal pain: are the effects dependent on gender?

The aim of the present study was to evaluate the outcome of a behavioral medicine (BM) rehabilitation program and the outcome of its two main components, compared to a 'treatment-as-usual' control group (CG). The study employed a 4x4 repeated-measures design with four groups and four assessment periods (pre-treatment, post-treatment, 6-month follow-up, and 18-month follow-up). The group studied consisted of subjects on sick leave identified in a nationwide health insurance scheme in Sweden. After inclusion, the subjects were randomized to one of four conditions, which were: (1) behavior-oriented physical therapy (PT); (2) cognitive behavioral therapy (CBT); (3) BM rehabilitation consisting of PT+CBT (BM); (4) a 'treatment-as-usual' CG. The treatments were given over a period of 4 weeks, PT and CBT on a part-time basis and BM on a full-time basis. Outcome variables were sick leave, early retirement, and health-related quality of life (measured using the Short Form Health Survey, SF-36). The results showed that the risk of being granted full-time early retirement was significantly lower for females in PT and CBT compared to the CG during the 18-month follow-up period. However, the total absence from work (sick listing plus early retirement) in days over the 18-month follow-up period was not significantly different in the CG compared to the treatments. On the SF-36, women in CBT and BM reported a significantly better health-related quality of life than women in the CG at the 18-month follow-up. No significant differences for men were found on the SF-36 scales. In conclusion, the results revealed gender differences in the outcome of the treatments and that the components of this BM program yielded as good results as the whole program.

A physiotherapy test package for assessing back and neck dysfunction--discriminative ability for patients versus healthy control subjects.

BACKGROUND AND PURPOSE: A physiotherapy test package of 10 tests designed for assessing dysfunction due to back or neck pain was tested for its ability to discriminate between back- or neck-pain sufferers and healthy control subjects. Twenty-seven patients and 26 healthy control subjects participated in the study. METHOD: Fifteen patients suffering from back or neck pain and 15 matched healthy control subjects were assessed using the package to compare the results between the groups. The results from a further 12 back- or neck-pain sufferers and 11 unmatched healthy control subjects were analysed with respect to sensitivity and specificity, cluster formation and correlation with ratings of pain and perceived exertion. RESULTS: The differences in the test results for the patients and the matched healthy control subjects were highly significant in all variables but one. High sensitivity for cut-off points of clinical relevance was found in all variables but one, whereas specificity was moderate in most variables. CONCLUSIONS: Despite the small sample size, the significant differences between patients and healthy control subjects, with the sensitivity and specificity figures, suggest that the content validity of the test package is satisfactory.

Intra- and inter-rater reliability of an 11-test package for assessing dysfunction due to back or neck pain.

BACKGROUND AND PURPOSE: The intra- and inter-rater reliability of 11 tests assembled by physiotherapists for clinical purposes was investigated. Forty-five patients and 23 healthy volunteers participated in the study. METHOD: Twenty-one patients were tested simultaneously and independently by two physiotherapists to determine inter-rater reliability for two raters. Twenty-four patients and 11 healthy volunteers were tested by one physiotherapist three times in a week to determine intra-rater reliability over time. Twelve healthy volunteers were tested by three different physiotherapists in a week to determine inter-rater reliability for three raters. RESULTS: Inter-rater agreement for two simultaneous raters was clinically acceptable. Repeatability on three test occasions was clinically acceptable in six of the 11 tests. There were no systematic differences between occasions. CONCLUSIONS: Intra- and inter-rater reliability was acceptable for six of the 11 tests in the form described here: three gait tests, two functional lifting tests and a functional muscular endurance test in the right leg. If these tests are to be used as outcome measures, account must be taken of the size of the typical fluctuation in measurements shown. The repeatability figures given may be used as guidelines for interpreting the clinical value of possible changes in test values.
