OBJECTIVE: To examine the influence of determinants on the Shoulder Pain and
Disability Index. Baseline registrations were
applied. PATIENTS: Two hundred patients with subacromial shoulder pain lasting at
least 3 months. METHODS:
A questionnaire consisting of possible determinants, 2
independent variables regarding pain and 2 regarding function, and the outcome
measurement. Two multiple regression models (one with and one without the
independent variables of pain and function) for the Shoulder Pain and Disability
Index, the 2 subscales, and the determinants, were performed. RESULTS: The
included determinants explained 29% of the variance of the Shoulder Pain and
Disability Index (25% for pain and 33% for disability subscale) with pain
medication, emotional distress, flexion, and the hand-behind-back range
accounting for 26%. When pain and function were included, the final model
explained 65% of the variance, with gender, education and range of flexion showing significance. CONCLUSION: The determinants explained 26% of the variance
of the Shoulder Pain and Disability Index, but explained only a minor proportion
when pain and function were included. This supports the Shoulder Pain and
Disability Index as a shoulder pain and disability questionnaire.
