The Constant-Murley Shoulder Score, Explained

What is the Constant-Murley shoulder score?

The Constant-Murley score rates a shoulder out of 100 points across four domains — pain, activities of daily living, range of motion, and strength — with a higher total meaning better shoulder function 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change.. Christopher Constant and Alan Murley published it in 1987 as a deliberate composite: what the patient reports plus what an examiner measures, returned as one figure 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change..

That design was the point. Constant and Murley built the method to apply irrespective of diagnosis or what an X-ray shows 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change. — a torn cuff, a stiff capsule, and a shoulder five years past a replacement are assessed the same way, which is what makes the number comparable across years. The method also records each individual parameter while yielding an overall functional assessment 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change.. Both exist in your chart: the total, and the four numbers under it.

The Constant-Murley score is not a questionnaire. It is an examination with a questionnaire inside it.

Which parts do you fill in, and which does the clinician measure?

You supply the subjective portion: what the pain is like, and how the shoulder affects your ordinary activities. A clinician supplies the objective portion, measuring how far the arm travels and how much force it produces. The instrument is defined as the combination of the two 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change. — which is why there is no honest way to self-administer it. You can answer your part of the form and still not have a score.

This is unusual enough that the outcome-measure literature marks it. When the Oxford group built their own shoulder questionnaire in 1996 — a 12-item form the patient completes alone, developed from patient interviews — they validated it partly against the surgeon-rated Constant score, using the correlation as evidence their form captured something real 2Ref 2Dawson J, Fitzpatrick R, Carr A (1996).Questionnaire on the perceptions of patients about shoulder surgery.That the Oxford Shoulder Score is a 12-item patient-completed questionnaire developed from patient interviews; that it was validated prospectively against comparators including the surgeon-rated Constant score, with construct validity established via correlations with it; and that it was built for the outcomes of shoulder surgery excluding shoulder stabilisation, instability being covered by a separate instrument. Not cited for the Oxford Shoulder Score's range, direction, or any change threshold.. The Constant score was the clinician's yardstick; the new form was earning a place beside it.

The same instinct shows up one joint down. The Harris Hip Score, published in 1969, is likewise clinician-administered and likewise totals 100 points — but it splits them very differently: 44 for pain, 47 for functional capacity, 5 for range of motion, and 4 for absence of deformity, higher meaning a better hip 3Ref 3Harris WH (1969).Traumatic arthritis of the hip after dislocation and acetabular fractures: treatment by mold arthroplasty. An end-result study using a new method of result evaluation.That the Harris Hip Score is a clinician-administered 100-point scale published in 1969, composed of pain (44 points), functional capacity (47), range of motion (5), and absence of deformity (4), scored so that higher totals indicate a better hip — used here as the hip parallel to Constant-Murley's clinician-administered composite design.. Each weighting tells you what that joint is for. A hip is for walking; a shoulder is for reaching.

What do the four domains actually measure?

Four things, in two currencies. Pain and daily activity are denominated in your experience: what the shoulder does to your life. Range of motion and strength are denominated in measurement: degrees the arm travels, force it produces. Constant and Murley named all four and scored them into one total out of 100 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change.. Here is who supplies what.

That table answers the question most people arrive with. You cannot fill in the bottom two rows. Anything offered online as a Constant-Murley calculator is asking you to estimate the two things the instrument exists to measure.

Activities of daily living is the clinical phrase for the ordinary business of a day: dressing, reaching a shelf, sleeping on that side, doing your job. It is where a shoulder problem stops being an abstraction and starts being a Tuesday.

What does a Constant-Murley number mean on its own?

Less than you would like. The 1987 paper establishes the range and the direction, and then stops. It sets no severity bands, no threshold for how many points count as a real improvement, and no line above which a shoulder counts as good 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change.. A single total, read cold, is a position, not a verdict.

The paper that created the Constant-Murley score sets its range at 0 to 100 and its direction — higher is better — but publishes no severity bands and no threshold for meaningful change 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change..

So the cutoffs you may find quoted — a score above one number is excellent, below another is poor — did not come from the instrument's own paper 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change.. If a clinician calls your total good or poor, where that band came from is a fair question. A raw total also carries no sense of what would be ordinary for a shoulder of your age; the original paper supplies no such reference 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change..

There is a second reason the total is slippery. Because it blends four domains into one figure, two shoulders can land on the same number for opposite reasons. This is the pain versus function outcomes problem in miniature: a shoulder that has stopped hurting but cannot reach the top shelf, and a shoulder that reaches fine but aches all night, can total the same. The total will not tell them apart. The four domain numbers will.

How it compares with the questionnaires you fill in yourself

Most shoulder outcome measures are pure self-report, and Constant-Murley is not. That is the whole difference. The Oxford Shoulder Score is 12 items, built from patient interviews and completed by the patient alone 2Ref 2Dawson J, Fitzpatrick R, Carr A (1996).Questionnaire on the perceptions of patients about shoulder surgery.That the Oxford Shoulder Score is a 12-item patient-completed questionnaire developed from patient interviews; that it was validated prospectively against comparators including the surgeon-rated Constant score, with construct validity established via correlations with it; and that it was built for the outcomes of shoulder surgery excluding shoulder stabilisation, instability being covered by a separate instrument. Not cited for the Oxford Shoulder Score's range, direction, or any change threshold.. The DASH covers symptoms and physical function across the whole arm rather than the shoulder in isolation, and is likewise self-reported 4Ref 4Hudak PL, Amadio PC, Bombardier C (Upper Extremity Collaborative Group) (1996).Development of an upper extremity outcome measure: the DASH (disabilities of the arm, shoulder, and hand).That the DASH is a self-reported measure of symptoms and physical function developed to span upper-extremity musculoskeletal disorders rather than a single joint.. Neither needs an examiner in the room.

The trade is straightforward. A self-completed form can be posted or filled in a waiting room, which is why registries and trials lean on them — but the number is then entirely your account, with nothing measured against it. Constant-Murley buys objectivity and pays for it in access: an appointment, an examiner, and that examiner's technique.

The Oxford Shoulder Score was also developed for shoulder-surgery outcomes and explicitly excludes shoulder stabilisation — instability got its own separate instrument 2Ref 2Dawson J, Fitzpatrick R, Carr A (1996).Questionnaire on the perceptions of patients about shoulder surgery.That the Oxford Shoulder Score is a 12-item patient-completed questionnaire developed from patient interviews; that it was validated prospectively against comparators including the surgeon-rated Constant score, with construct validity established via correlations with it; and that it was built for the outcomes of shoulder surgery excluding shoulder stabilisation, instability being covered by a separate instrument. Not cited for the Oxford Shoulder Score's range, direction, or any change threshold.. A form used outside the population it was validated in is doing something it was not designed to do.

A third approach sidesteps the interpretation problem entirely. PROMIS Physical Function reports no raw total at all: it reports a T-score normed to a mean of 50 and a standard deviation of 10 in a US general population sample, higher meaning better physical function, drawn from a bank of 124 calibrated items 5Ref 5Rose M, Bjorner JB, Gandek B, Bruce B, Fries JF, Ware JE Jr. (2014).The PROMIS Physical Function item bank was calibrated to a standardized metric and shown to improve measurement efficiency.That PROMIS Physical Function reports on a standardized T-score metric normed to a mean of 50 and a standard deviation of 10 in a US general population sample, with higher scores indicating better physical function, drawn from a bank of 124 IRT-calibrated items.. A 50 means average for the population — precisely the thing a Constant-Murley total, on its own, cannot tell you.

Does the score move when you actually get better?

Constant and Murley reported that their method was reproducible between different observers and sensitive to small changes in function 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change.. Read that precisely: those are the developers' findings about their own instrument, in the paper that introduced it. They are a good reason to take the score seriously. They are not independent validation, which belongs to later papers.

The observer part matters more than it sounds. Two of the four domains are measured by a person, so the score quietly inherits that person's technique. Five points of movement between two visits with two different examiners is a different piece of evidence from five points measured twice by the same clinician. The original claim was that the method holds up between observers 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change. — a designed property, tested by its designers, rather than a guarantee about any particular clinic.

A score that has barely moved in three months is not automatically a failing treatment. Some shoulder conditions run on their own clock. Frozen shoulder moves through freezing, frozen, and thawing stages and usually resolves over one to three years, with range-of-motion physical therapy as the main treatment 6Ref 6American Academy of Orthopaedic Surgeons (OrthoInfo) (2024).Frozen Shoulder (Adhesive Capsulitis).That frozen shoulder progresses through freezing, frozen, and thawing stages, usually resolves over one to three years, and is primarily treated with range-of-motion physical therapy.. Against a natural history measured in years, a score that has crept up over a quarter is not a disappointing result. It is a slow measurement of a slow thing.

What to ask about the number at your next appointment

The most useful move is to ask for the parts, not just the total. Because the method records each individual parameter alongside the overall figure 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change., the four domain numbers already exist in your chart even when only the total gets said out loud. Those four are what rehabilitation decisions turn on: whether the work ahead is about pain, motion, or strength is a different conversation each time.

• The domain breakdown. Worth asking whether the four figures can be read out separately rather than only summed 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change..
• Who measured it, and when. The examiner-measured portion depends on a person doing the measuring; a score from a different clinician on a different day carries that inside it.
• Where any band came from. If a total gets called good or poor, the source of that cutoff is a fair question — the original paper sets none 1Ref 1Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.The Constant-Murley score's origin and 1987 authorship; its 0-100 range and higher-is-better direction; its four domains (pain, activities of daily living, range of motion, strength); its composite design combining subjective and objective components; its applicability irrespective of diagnosis or radiologic abnormality; its recording of individual parameters alongside an overall functional assessment; and the developers' own claims of inter-observer reproducibility and sensitivity to small changes. Also cited for what the paper does not establish: no severity bands, no normative reference, and no threshold for meaningful change..
• What the same shoulder scored last time. One total is a position. Two totals are a direction, and direction is the one thing a single visit cannot give you.

None of this is about arguing with the number. It is about getting the number to say what it actually knows.
