Abstract

Background:

Outcome measurements are used to validate chiropractic adjustments, and they have not always been compared to each other under the same treatment conditions and trials.

Methods:

Twenty-one participants were non-randomly assigned to a treatment or a control group. The Oswestry index questionnaire was completed, and lateral bending lumbar radiographs were collected. Treatment group participants received nine treatments in two weeks, the control group was untreated, and both groups were re-evaluated after two weeks.

Results:

The average number of segments manipulated per day went from 8.3 ± 1.0 (day 1) to 3.0 ± 2.6 (day 9), with a standardized effect size of 2.69. The Oswestry disability index for the treatment group was 29.8% ± 11.8% disability pre-treatment and 14.20% ± 11.5% disability post-treatment, with a standardized effect size of 1.34. In the radiograph analysis, the number of dysfunctional segments changed from 6.8 ± 2.3 pre-treatment to 1.8 ± 5.2 post-treatment, with a standardized effect size of 1.24.

Conclusion:

A significant correlation was found between pre- and post-treatment measurements of the Oswestry index and dynamic radiographs.
