The ASES Shoulder Score Your Surgeon Records

What is the ASES shoulder score?

The score comes from a standardized shoulder assessment form that the American Shoulder and Elbow Surgeons adopted in 1994, so a result recorded in one hospital could be read against one recorded in another. The form has two halves that never mix: a patient self-evaluation, completed by the person with the shoulder, and a physician assessment, completed by the clinician after examining it 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work..

The self-evaluation holds three things. A visual analog scale for pain. A second visual analog scale for instability — the sensation of the shoulder slipping or giving way. And a ten-item questionnaire about activities of daily living, in which each activity is rated on a four-point scale running from 0, unable to perform, to 3, no difficulty 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work..

A visual analog scale is a plain line with an anchor at each end; you place a mark somewhere along it, and the distance from one end becomes the number. It exists because most people mark a line more consistently than they choose between words like moderate and severe.

Activities of daily living is the clinical phrase for the ordinary business of washing, dressing, reaching and lifting. Ten of them sit on the form, and their exact wording belongs to the society that publishes it, so they are characterised here rather than reprinted.

How is the 0-to-100 number worked out?

Two halves, weighted equally. The pain scale supplies half of the score and the cumulative activities-of-daily-living score supplies the other half, and together they produce a range from 0 to 100 in which a higher number means less pain and better function 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work.. Nothing else on the form enters that calculation.

The equal weighting has a consequence worth holding on to. Pain is captured by one mark on one line, and that mark carries as much weight as all ten activity questions combined. Half an ASES score rests on a single pain mark; the other half is spread across ten activities. A run of bad nights can move the total a long way without anything changing in what the arm can do, while a shoulder that has quietly stiffened may lose points slowly with the pain line barely shifting.

That is a fact about the instrument rather than a flaw in it, and it is why the two halves are worth reading side by side, not only as a combined figure. The total is also not a percentage of anything. A 100 is the ceiling of the scale, not a shoulder restored to how it worked at twenty.

The parts of the form that are recorded but never counted

There are two. The instability scale and the whole physician assessment section get filled in, but neither contributes to the 0-to-100 figure — that number is built from the pain scale and the activities score alone 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work.. Everything the examiner measures sits beside the score rather than inside it.

For most people this is invisible and harmless. For someone whose main complaint is a shoulder that slips or gives way, it matters: the sensation that brought them in is recorded and then left out of the figure being tracked. A clinician still reads that line. It just will not move the score.

The opposite design exists. The constant-murley score is a composite scored out of 100 points across four domains — pain, activities of daily living, range of motion and strength — with higher meaning better function 2Ref 2Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.That the Constant-Murley score is a composite shoulder-function measure combining subjective and objective components, scored out of 100 points across pain, activities of daily living, range of motion and strength, with higher scores indicating better function; and the authors' developmental claims that the method applies irrespective of diagnosis or radiologic abnormality, is reproducible between different observers, and is sensitive to small changes in function.. Two of those four are measured by a clinician rather than reported by a patient, so an examiner's findings are inside the total by construction. Constant and Murley built their method to apply irrespective of the diagnosis or what the radiographs show, and reported it as reproducible between observers and sensitive to small changes in function 2Ref 2Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.That the Constant-Murley score is a composite shoulder-function measure combining subjective and objective components, scored out of 100 points across pain, activities of daily living, range of motion and strength, with higher scores indicating better function; and the authors' developmental claims that the method applies irrespective of diagnosis or radiologic abnormality, is reproducible between different observers, and is sensitive to small changes in function..

Neither arrangement is correct in the abstract. One keeps the patient's account unmixed; the other draws a fuller picture at the cost of needing a clinician in the room.

Why the founding paper contains no reliability figures

Because it is a consensus document, not a validation study. The 1994 paper records a committee agreeing on a standardized method of assessing shoulder function — what to ask, and how to add the answers up. It is not an experiment testing whether the resulting number behaves well, and the reliability, validity and responsiveness of the patient self-report section were established only in later work 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work..

Three absences follow. The paper carries no minimal clinically important difference, no minimal detectable change, and no cutoffs 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work.. So the document that defines the score does not say how many points amount to a real improvement, how many points are ordinary noise, or what figure divides a good shoulder from a poor one.

Those numbers do exist, in separate studies, and they differ by condition and by population — the change that means something after a shoulder replacement is not the change that means something in a cuff problem treated without an operation. A clinician quoting a threshold is drawing on that later literature, and the useful question is which population it came from.

A single ASES number is not a verdict, and there is no line on the scale a shoulder is supposed to clear.

Higher is better here — and worse on the next form

Direction belongs to each questionnaire, not to shoulder scores as a family. On the ASES, a bigger number is a better shoulder, with 100 at the top 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work.. On the constant-murley shoulder score, bigger is likewise better 2Ref 2Constant CR, Murley AH (1987).A clinical method of functional assessment of the shoulder.That the Constant-Murley score is a composite shoulder-function measure combining subjective and objective components, scored out of 100 points across pain, activities of daily living, range of motion and strength, with higher scores indicating better function; and the authors' developmental claims that the method applies irrespective of diagnosis or radiologic abnormality, is reproducible between different observers, and is sensitive to small changes in function.. But that is a convention rather than a rule, and one figure can be encouraging on one form and discouraging on the next.

The Oxford Shoulder Score shows this most clearly. It is a twelve-item questionnaire developed out of patient interviews and validated in 111 people assessed before shoulder surgery and again at six months, with construct validity established against the surgeon-rated Constant score 4Ref 4Dawson J, Fitzpatrick R, Carr A (1996).Questionnaire on the perceptions of patients about shoulder surgery.The Oxford Shoulder Score's 12-item structure, its development from patient interviews and prospective validation in 111 patients assessed before shoulder surgery and again at six months, its high internal consistency and construct validity established against the surgeon-rated Constant score, its intended population of shoulder surgery excluding stabilisation (instability being covered by a separate Oxford questionnaire), and its original 1996 scoring in which the total ran 12 to 60 with 12 as the best outcome.. In its original 1996 scoring the total ran from 12 to 60, and 12 was the best possible outcome — the low number was the good one 4Ref 4Dawson J, Fitzpatrick R, Carr A (1996).Questionnaire on the perceptions of patients about shoulder surgery.The Oxford Shoulder Score's 12-item structure, its development from patient interviews and prospective validation in 111 patients assessed before shoulder surgery and again at six months, its high internal consistency and construct validity established against the surgeon-rated Constant score, its intended population of shoulder surgery excluding stabilisation (instability being covered by a separate Oxford questionnaire), and its original 1996 scoring in which the total ran 12 to 60 with 12 as the best outcome.. Scoring conventions have been revised over the decades, which is why the range printed on the sheet matters as much as the figure written on it. That form was also built for shoulder surgery other than stabilisation; instability has its own separate Oxford questionnaire 4Ref 4Dawson J, Fitzpatrick R, Carr A (1996).Questionnaire on the perceptions of patients about shoulder surgery.The Oxford Shoulder Score's 12-item structure, its development from patient interviews and prospective validation in 111 patients assessed before shoulder surgery and again at six months, its high internal consistency and construct validity established against the surgeon-rated Constant score, its intended population of shoulder surgery excluding stabilisation (instability being covered by a separate Oxford questionnaire), and its original 1996 scoring in which the total ran 12 to 60 with 12 as the best outcome..

The shoulder pain and disability index takes a third shape: thirteen self-administered items split into a five-item pain subscale and an eight-item disability subscale 3Ref 3Roach KE, Budiman-Mak E, Songsiridej N, Lertratanakul Y (1991).Development of a shoulder pain and disability index.That the Shoulder Pain and Disability Index is self-administered and comprises 13 items across two subscales — pain (5 items) and disability (8 items).. The spadi keeps those two subscales visible rather than merging them.

Ask which form a number came from before deciding whether it is good news.

What an ASES score cannot tell you

It cannot say what is wrong. The form records consequences — how much the shoulder hurts, how much it interferes — and contains nothing capable of separating one cause from another. A frozen capsule, a torn cuff tendon, an arthritic joint and a shoulder that keeps slipping can all arrive at the same total by different routes.

It cannot grade severity either, because the defining paper sets no bands 1Ref 1Richards RR, An KN, Bigliani LU, et al. (1994).A standardized method for the assessment of shoulder function.The ASES Shoulder Score's structure and scoring as adopted by the American Shoulder and Elbow Surgeons: a patient self-evaluation section containing a visual analog scale for pain, a visual analog scale for instability, and a 10-item activities-of-daily-living questionnaire scored on a 4-point ordinal scale from 0 (unable to perform) to 3 (no difficulty), plus a separate physician assessment section; the score derived equally from the pain scale and the cumulative activities score to give a 0-100 range in which higher indicates better function and less pain; the exclusion of the instability scale and the physician section from that score; and the fact that this is a committee consensus description of the form containing no MCID, no MDC and no cutoffs, with reliability, validity and responsiveness for the self-report section established only in later work.. No score turns a shoulder officially mild or officially severe; a clinic using those labels has imported thresholds from somewhere else. And it does not convert. An ASES of 70 and a 70 on some other shoulder questionnaire are two unrelated facts with no exchange rate between them.

What the form does well is the thing a clinic appointment is worst at. It holds a record of what the shoulder has been doing across whole weeks, rather than what a person can reconstruct from memory in ten minutes in a consulting room. That record earns its keep by being repeated — same form, same person, several times — because the shape of the line matters far more than any single point on it. Making sense of shoulder pain still takes a history and an examination.

When the problem is the whole arm, not the shoulder

A shoulder-specific form asks about the shoulder, which becomes a limitation the moment an arm has more than one problem. The DASH was developed for that case: a self-reported measure of symptoms and physical function built to span upper-extremity musculoskeletal disorders as a whole rather than one joint 6Ref 6Hudak 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 validated self-reported measure of symptoms and physical function developed to span upper-extremity musculoskeletal disorders as a whole rather than a single joint.. Someone with a stiff shoulder and a painful thumb is a different measurement problem from someone with only the shoulder.

The same logic runs through the rest of the body. The oxford hip score, for instance, is a twelve-item patient-completed questionnaire covering hip pain and function in a single composite, validated in 220 patients assessed before an operation and again six months after 5Ref 5Dawson J, Fitzpatrick R, Carr A, Murray D. (1996).Questionnaire on the perceptions of patients about total hip replacement.That the Oxford Hip Score is a 12-item patient-completed questionnaire covering hip pain and function in a single composite score, developed and validated prospectively in 220 patients assessed pre-operatively and at six-month follow-up.. Different joint, identical question: what is this costing the person.

Which form someone meets usually depends on the clinic and the specialty rather than on the shoulder. Surgeons trained with the ASES use the ASES, a therapy department may use something else, and a study uses whatever its protocol specifies. None of that is a judgement about the joint.

Three questions make any of these numbers useful at a follow-up visit: which form is this, which direction does it run, and what was the figure last time. A score without a comparison is a data point with no line drawn through it, and the line is what a clinician is reading.
