Background and study aims
There is proof that the degree of agreement (inter-rater reliability) of Delitto's classification-based system for low back pain is moderate for physical therapists who are familiar with the classification system and the reliability is better in patients with a clear classification than in those with an unclear classification. This study aims to find out the inter-rater reliability of Delittos classification-based treatment for patients with low back pain.
Who can participate?
Adult patients with low back pain can participate in this study.
What does the study involve?
Patients were examined twice on the same day by two of three therapists with different levels of familiarity with the system. Patients were classified into one of four groups. The physical therapists were blind to the other's classification decision. To quantify the inter-rater reliability, percentages of agreement was calculated.
What are the possible benefits and risks of participating?
There are no benefits from taking part in our study. There were hardly any risks for the patients.
Where is the study run from?
Patients were recruited in the Medical Back Neck Centre, an outpatient private practice in the Hague, Netherlands.
When is the study starting and how long is it expected to run for?
Patients were recruited from April 2009 to December 2010.

| Scientific title | Inter-rater reliability of a modified version of Delitto's classification-based system for low back pain: an observational study |
| Study objectives | To examine: 1. the inter-rater reliability of Delittos classification-based treatment system for patients with low back pain. 2. the influence of different levels of familiarity with the system. 3. the inter-rater reliability of algorithm decisions in patients who clearly fit into a subgroup (clear classifications) and who do not (unclear classifications). |

| Health condition(s) or problem(s) studied | Low back pain |
| Intervention | Patients were examined twice on the same day by two of three participating physical therapists with different levels of familiarity with the system. Patients were classified into one of four classification groups. The physical therapists were blind to the other's classification decision. To quantify the inter-rater reliability, percentages of agreement and Cohens kappa were calculated. |

| Primary outcome measure | The prevalence of each of the four classifications was calculated for the three participating physical therapists. |
