DASH Score Interpretation: Scoring, QuickDASH and MCID Guide

DASH score interpretation in one line: the DASH (Disabilities of the Arm, Shoulder and Hand) is scored 0 to 100, where 0 means no disability and 100 means the most severe disability. The general population averages about 10. In a survey of DASH users run by the Institute for Work & Health (IWH), most saw scores of 0 to 29 as "no longer a problem" and 40 to 69 as "a lot of difficulty". A change of roughly 10 to 15 points on the DASH, or about 8 to 16 on the QuickDASH, is the usual threshold for a clinically meaningful change.

This quick guide explains what the DASH questionnaire is, how DASH scoring works, how to read DASH and QuickDASH scores, which MCID to use, and how to document results. Use the calculator below to score a completed form.

DASH score interpretation at a glance

The DASH has no official severity cut-offs. IWH notes the score is best used to track change in the same patient over time and to compare groups, with the ranges above as a guide. Source: IWH DASH frequently asked questions.

What is the DASH questionnaire?

The DASH questionnaire is a 30-item, self-reported patient-reported outcome measure (PROM) of physical function and symptoms in people with any musculoskeletal disorder of the upper limb. It was developed by the Institute for Work & Health and the American Academy of Orthopaedic Surgeons, and it treats the arm as one functional unit, so it works for shoulder, elbow, wrist and hand conditions alike.

So, what is the DASH test in practice? The patient rates how hard everyday tasks were in the past week, such as opening a tight jar, carrying a shopping bag, washing their back or using a knife, and rates symptoms such as pain, tingling, weakness and sleep disturbance. There are also two optional 4-item modules: one for work and one for sports and performing arts.

DASH scoring: how to calculate the score

DASH scoring uses the same formula for the DASH, the QuickDASH and each module:

DASH score = [(sum of the answers ÷ number of items answered) − 1] × 25

1. Add the 1 to 5 answers for every item the patient completed.
2. Divide by the number of items answered to get the average answer (1 to 5).
3. Subtract 1, so the average runs from 0 to 4.
4. Multiply by 25 to put the result on a 0 to 100 scale.

Missing items and modules

• DASH: score only if at least 27 of the 30 items are answered.
• QuickDASH: score only if at least 10 of the 11 items are answered.
• Work and sports/performing arts modules: all 4 items must be answered. Each module is scored on its own and never added to the main score.

QuickDASH score interpretation

QuickDASH score interpretation works the same way as the full DASH: 0 to 100, with higher scores meaning more disability, and the same IWH survey ranges as a guide. Because the QuickDASH has fewer items, each answer moves the score more, so it has a larger measurement error. That is why its minimal detectable change (16 to 20 points) is bigger than the DASH's, and why the MCID you pick matters.

For example, a patient whose QuickDASH falls from 54.5 to 36.4 has improved by 18.1 points, which clears every MCID in the table below. A drop from 45.5 to 38.6 (6.9 points) is within measurement error and should not be reported as meaningful change on its own.

DASH MCID and QuickDASH MCID

The minimal clinically important difference (MCID) is the smallest change a patient would see as meaningful. Published values differ by population and method, so state which one you use in your documentation.

A practical rule: a change of 15 points or more on the DASH clears both MCIDs and its mean MDC95 (13 points), and a change of 18 points or more on the QuickDASH clears every MCID above and its mean MDC95 (18 points).

Using the DASH in physical and occupational therapy

Give the DASH at the initial evaluation, at re-evaluations and at discharge so you can show change against the MCID. It is commonly used for conditions such as shoulder impingement (ICD-10 M75.1 rotator cuff syndrome), carpal tunnel syndrome (G56.0) and lateral epicondylitis (M77.1).

• Record the version (DASH or QuickDASH), the score, items answered and any module scores.
• Write a functional goal tied to the score, for example: "QuickDASH from 52.3 to below 36 in 6 weeks so the patient can lift a full laundry basket."
• Note change against your chosen MCID at each re-evaluation to support medical necessity for therapeutic exercise (97110) and other skilled care.
• Collect the questionnaire digitally between visits with remote therapeutic monitoring.

SPRY's PROMs and functional outcomes tools send the DASH and QuickDASH to patients, score them automatically and chart the trend inside the note, while reporting and analytics shows outcomes across your caseload. See also SOAP documentation.

Escala DASH: interpretación (Spanish version)

La escala DASH (cuestionario DASH, Discapacidades del Brazo, Hombro y Mano) tiene versiones oficiales en español. Se puntúa igual: [(suma de respuestas ÷ número de respuestas) − 1] × 25, de 0 a 100. Interpretación: 0 significa sin discapacidad y 100 la máxima discapacidad. La media de la población general es de unos 10 puntos. Un cambio de unos 10 a 15 puntos en el DASH, o de 8 a 16 en el QuickDASH, suele considerarse clínicamente importante. Las versiones traducidas se obtienen en el sitio del IWH.

Licensing and where to get the form

The DASH and QuickDASH are copyrighted by the Institute for Work & Health. They are free to use for non-profit clinical care and research, while commercial use requires a licence fee. Always use the official item wording; the calculator on this page needs only the 1 to 5 answers.

Frequently asked questions

What is a good DASH score?

Lower is better. The general-population average is about 10, and in an IWH user survey most clinicians and researchers saw scores of 0 to 29 as the range where patients no longer consider their upper-limb problem a problem.

What does a DASH score of 40 mean?

A score of 40 falls in the 40 to 69 range that most IWH survey respondents linked to a patient having a lot of difficulty with upper-limb activities.

How do you interpret a QuickDASH score?

QuickDASH scores run from 0 (no disability) to 100 (most severe disability). Read them with the same ranges as the DASH and judge change over time against an MCID of about 8 to 16 points.

What is the MCID for the DASH?

IWH cites more than 15 points. Franchignoni et al. (2014) reported 10.83 points for the DASH and 15.91 points for the QuickDASH.

How is the DASH scored?

Take the average of the 1 to 5 answers, subtract 1, and multiply by 25. At least 27 of 30 items must be answered on the DASH, and 10 of 11 on the QuickDASH.

What is the difference between the DASH and the QuickDASH?

The QuickDASH is an 11-item short form of the 30-item DASH. Both score 0 to 100, but the QuickDASH is faster and has a larger measurement error.

Is the DASH questionnaire free to use?

It is free for non-profit clinical and research use. Commercial use, such as in software, needs a licence from the Institute for Work & Health.

Is there a Spanish version of the DASH scale?

Yes. Official Spanish translations of the DASH and QuickDASH are available from the Institute for Work & Health, which lists 54 official translations.
