Factor structure of the Shoulder Pain and Disability Index in patients with adhesive capsulitis

BACKGROUND The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire that aims to measure pain and disability associated with shoulder disease. It consists of a pain section and a disability section with 13 items being responded to on visual analogue scales.

Responsiveness of the Shoulder Pain and Disability Index in patients with adhesive capsulitis

BACKGROUND Instruments designed to measure the subjective impact of painful shoulder conditions have become essential in shoulder research. The Shoulder Pain and Disability Index (SPADI) is one of the most extensively used scales of this type. The objective of this study was to investigate reproducibility and responsiveness of the SPADI in patients with adhesive capsulitis. METHODS SPADI test...

The Effects of Photobiomodulation on Shoulder Pain, Muscle Thickness, and Function in Subjects With Adhesive Capsulitis
