Inter Rater Reliability and concurrent validity of Stroke Specific Shoulder Disability Index - A Cross Sectional Study.

There are many scales developed for assessment of upper extremity functions in stroke patients. But they could not include the shoulder domains like shoulder pain, subluxation, ROM and quality of life. A validated scale i.e. stroke specific shoulder disability index was developed which covers all domains. There is no specific study until date which calculate the inter rater reliability and concurrent validity of stroke specific shoulder disability index. So it is necessary to conduct a study which shows inter rater reliability and concurrent validity of this scale.
