The DASH score test
This questionnaire is designed to assess both your symptoms and your ability to carry out specific activities. Please respond to every question based on your condition over the past week. If you haven't had the chance to perform a particular activity during that time, do your best to estimate how you would have managed it. Your responses should reflect your overall ability, regardless of which hand or arm you typically use to complete the task.

At Panacea Therapy Co., we utilize the DASH (Disabilities of the Arm, Shoulder, and Hand) assessment—a trusted and standardized tool developed to measure the functional impact of musculoskeletal conditions affecting the upper extremities.
Originally published in 1996 in the American Journal of Industrial Medicine, the DASH was created through a collaborative effort by the American Academy of Orthopaedic Surgeons, the Council of Musculoskeletal Specialty Societies, and the Institute for Work and Health.
This 30-item self-reported questionnaire uses a 5-point Likert scale to evaluate a patient’s ability to perform daily tasks and the severity of their symptoms. Scores range from 0 (indicating no disability) to 100 (indicating the most severe disability), making it a valuable tool across a wide range of upper limb conditions. At Panacea, we rely on this evidence-based measure to guide treatment plans and track progress in restoring strength, mobility, and function.
At Panacea Therapy Co., our use of the DASH (Disabilities of the Arm, Shoulder, and Hand) assessment is grounded in a strong foundation of peer-reviewed research and clinical validation.
Original Literature
The DASH was first introduced in the landmark study by Hudak et al. (1996), “Development of an upper extremity outcome measure: the DASH,” published in the American Journal of Industrial Medicine. This foundational work laid the groundwork for a comprehensive tool to measure functional outcomes in individuals with upper extremity musculoskeletal conditions.
Validation Literature
Beaton et al. (2001) expanded on the DASH’s clinical utility in their study, “Measuring the whole or the parts? Validity, reliability, and responsiveness of the DASH outcome measure in different regions of the upper extremity,” published in Journal of Hand Therapy. This research confirmed the DASH’s strong validity, reliability, and responsiveness across various segments of the upper limb, reinforcing its effectiveness in clinical and rehabilitative settings.
Additional Literature
Further comparative research by Angst et al. (2011), featured in Arthritis Care & Research, evaluated the DASH and its abbreviated version (QuickDASH) alongside other widely used shoulder function measures. Their study confirmed the DASH’s standing as a robust, patient-centered outcome measure among tools like SPADI, ASES, SST, OSS, and WOSI.
At Panacea, we integrate this evidence-based assessment as part of our commitment to precision, progress tracking, and personalized upper extremity rehabilitation.
At Panacea Therapy Co., we recognize and value the contributions of leading researchers whose work has shaped the tools we use in clinical practice.
