Analysis

The Shoulder Disability Questionnaire (SDQ) is mainly used for assessing disability related to shoulder problems, such as pain, limited mobility, and functional restrictions.

Objective

The main objective of the SDQ is to measure the extent of shoulder-related disability and to understand how shoulder problems affect an individual’s daily activities. The collected data can be used for diagnosis, monitoring rehabilitation progress, evaluating the effectiveness of treatments, and adjusting therapeutic strategies.

Scoring

The SDQ includes a series of questions that assess pain, mobility, functionality, and psychological impact. The questions are usually scored on a 5-point Likert scale, ranging from 0 (not at all) to 4 (very much).
