Summary Date

Purpose

The ASES is a condition-specific scale that is intended to measure functional limitations and pain of the shoulder.

Description

  • The ASES is a 100 point scale that consists of two dimensions: pain and activities of daily living. There is one pain scale worth 50 points and ten activities of daily living worth 50 points. Patients can complete the questionnaire in less than five minutes (Leggin, 2006).
  • The patient self assessment (pASES) includes 6 pain items and 10 functional items that are shoulder specific (Angst, 2008).
  • The pASES form has 3 sections: pain, instability, ADL’s. (Goldhahn 2008).
    • Pain section: 4 questions with yes/no responses, 1 question covering number of pain tablets per day, and a VAS scale from 0 (no pain) to 10 (worst pain).
    • Instability section: 2 questions (1. Response yes/no about feelings of instability, 2. Quantify instability from 0 (stable) to 10 (very unstable).
    • ADL’s: Each shoulder is included (affected/non affected), 10 items, with a 4 point ordinal scale, range: 0 (unable to perform activity) to 3 (no difficulty in doing activity) (Goldhahn 2008).
  • ASES-s contains 2 parts: patient self evaluation and physician assessment.  Self evaluation: visual analog scales for assessment of pain/instability, ADL: utilizes 4 point scale, 3 min to fill out (Dowrick 2004).
  • Modified ASES eliminates “sleep on painful side” and “throw ball overhead”, and adds “open a jar of food”, “cut with a knife”, “use a phone”, “do up buttons”, and “carry shopping bag” (Beaton 1998).
  • Originally made as: “baseline measure of shoulder function, applicable to all patients regardless of diagnosis.” Was designed with aspiration to be utilized widely (Goldhahn 2008).
  • When it was created (ASES-s) it was supposed to be a “state-of-the-art questionnaire” with three main components: 1. Ease of use, 2. Method of assessing ADL’s, 3. Inclusion of a patient self-evaluation section (Goldhahn 2008).

Populations Tested

Shoulder Dysfunction (Michener, 2002) 
 
Individuals with a PT diagnosis of shoulder dysfunction. They were recruited from outpatient clinics. Individuals were excluded if they could not complete the form due to cognitive impairments, illiteracy, or inability to speak English. Age 51.7, range 20-81 years old. Mean height 167.6 cm and mean weight 78.9 kg. There were 37 males and 26 females. The time since onset was as follows: <1 month: 9 individuals, 1-3 months: 22 individuals, 3-6 months: 6 individuals, and >6 months: 26 individuals. Forty-three participants were working, 20 were not working. Three participants were involved in litigation.
 
Shoulder Dysfunction [instability, dislocation, humeral fracture] (Dowrick 2004)
 
Search of Medline database between January 1966-February 2004. Keywords: orthopaedic, outcome measure, trauma, upper extremity, upper limb, arm injury, instrument, assessment, function. Articles had to be written in English.  Hand search: 6 medical journals 1998-2003 included outcome measures: Injury, The Journal of Bone and Joint Surgery (American volume), The Journal of Hand Surgery (American volume), The Journal of Bone and Joint Surgery (British volume), Journal of Hand Surgery (British volume), Journal of Trauma. Criteria met to select outcome assessment measures: 1. patient self-evaluation of MSK disorders of UE, 2.previous use in orthopaedic trauma population (fracture/dislocation). Measures that included PEDS were excluded.
 
Shoulder Trauma (Slobogean, 2011)
 
Medline was searched using keywords including: shoulder; fracture; clavicle; scapula or proximal humerus; psychometric; clinimetric; reliability; validity; or responsiveness. ASES was reviewed based on its use in shoulder trauma patients. ASES score has been used in several fracture studies but no psychometric studies of the ASES in a fracture population had been performed at the time of this study.
 
Rotator Cuff, SLAP, and Instability Surgeries (Oh, 2009)
 
Two hundred eighty-five consecutive patients of a surgeon participated in this study and 193 completed the ASES prior to surgery. A small number of people were excluded if they had a diagnosis of OA, RA, or synovial disorders such as pigmented villonodular synovitis and proximal humerus fracture. Mean age 48.6 years (range, 19-78), 104 women and 181 men, 193 (67%) had rotator cuff disorders with or without other associated injuries, 45 (16%) had isolated superior labral anterior posterior (SLAP) lesions, and 51 (17%) had shoulder instability. Surgery was arthroscopic or arthroscopy-assisted performed by a single surgeon. Outcome measures were given preoperatively and postoperatively at 3, 6, 9, and 12 months and at final follow-up.
 
Shoulder Arthroplasty (Angst, 2008)
 
One hundred thirty-eight patients with osteoarthritis or rheumatoid arthritis who were receiving total shoulder arthroplasty in which pain relief and functional improvement are emphasized. Age range 39.5-88.5 year, median of 69.1 years. (Goldhahn 2008) 118 patients following shoulder arthroplasty. Ages 32-89, test and retest data examined 1.2 -7.9 years postoperatively, 77 women, 31 males. 7 patients: operated bilaterally, of 125 operations: 20: hemiarthroplasties, 105: total arthroplasties.
 
Variety of Shoulder Disorders (Leggin, 2006)
 
Twenty-two men (mean age 42.4 +/- 11.7 years) and 18 women (mean age 54.8 +/- 17.1 years) with a variety of shoulder disorders including, impingement/tendonitis, rotator cuff tear, instability, adhesive capsulitis, proximal humerus fracture, AC joint arthritis, and glenohumeral joint arthritis. (Ge, 2013) Individuals with diagnosis of rotator cuff tear, biceps tendon injury, subacromial impingement, labrum injury, frozen shoulder, tendinopathy, and undefined shoulder pain or discomfort.
 
Shoulder Pain (Beaton, 1998)
 
99 patients with shoulder pain
Shoulder problems: (Bott, 2004) patients with shoulder problems that were experiencing pain, problems or symptoms
Shoulder Dysfunction: (Cook, 2002) Patients without a particular shoulder conditions were recruited from a private-practice orthopedic surgeon who treats shoulder dysfunction.
 
Full Spectrum RC Pathology (Kirkley, 2003)
 
7 patients undergoing arthroscopy plus subacromial decompression for cuff tendinosis, 13 undergoing physiotherapy for cuff tendinosis or small full thickness cuff tears, and 77 undergoing subacromial injection or cuff tendinosis or small full-thickness cuff tears.
 
Non-specific Patient Population (Richards, 1994)
 
The ASES standardized shoulder assessment form is offered as a baseline measure of shoulder function applicable to all patients regardless of diagnosis.
 
Shoulder instability, Rotator Cuff Disease, Glenohumeral Arthritis: (Kocher, 2005)
 
 3 groups; Group A to assess test-retest reliability, Group B to assess internal consistency, content validity, construct validity, and responsiveness, and Group C to evaluate criterion validity. Group A used 21 patients with shoulder instability, 20 patients with rotator cuff disease, and 15 patients with glenohumeral arthritis. 34 patients were male, 22 were female, with a mean age of 49.5 years. Group B used 455 patients with instability, 474 with rotator cuff disease, and 137 with arthritis. 751 subjects were male, 315 were female, with a mean age of 30.3 for the instability group, 56.1 for the rotator cuff group, and 62.3 for the arthritis group. Group C used 68 patients with instability, 30 patients with rotator cuff disease, and 8 patients with arthritis. 70 overall were male, 36 were female, with a mean age of 30.5 for the instability group, 56.5 for the rotator cuff group, and 61.5 for the arthritis group. All data came from computerized records of patients who were undergoing shoulder surgery at a major sports medicine clinic.
 
Patients without Shoulder Problems (Sallay, 2003)
 
Individuals without any known shoulder disorder were recruited from 2 subspecialty outpatient clinics, and were being seen for conditions unrelated to the shoulder. 343 subjects total, 185 male and 158 female with a mean age of 42.8.

Professional Association Recommendations

Reliability by Surgical Status of Self-Reported Outcomes in Patients Who Have Shoulder Pathologies: (Cook, 2002)
  • Recommendations: for use based on acuity level of the patient, based on level of care in which the assessment is taken, based on SCI AIS Classification, based on EDSS Classification, for entry-level physical therapy education and use in research

Considerations

Shoulder Dysfuntion: (Cook, 2002)

  • Lack of a gold standard for comparing estimates of shoulder outcome variables.
  • Self-reported function, disability, and satisfaction may be compared across measure and across time, but there is no external referent by which the scales’ external validity can be established.
  • The small sample size also limited the current study.
  • A larger pool of participants would have narrowed the confidence intervals around the calculated ICC values and may have broadened the conclusions that could be drawn from the results.
  • No control over when patients actually completed the second questionnaire.
  • After completing the first questionnaire, participants were given a blank second copy and asked to return this copy 1 week later. It is possible that some patients completed the second questionnaire after less than the requested amount of time had elapsed.

 

Shoulder instability, Rotator cuff disease, Glenohumeral arthritis: (Kocher, 2005) Study limitations include the use of a large, prospectively maintained computerized database, heterogeneity among the patients, and variation in the specific surgical techniques used. All psychometric properties of the ASES were acceptable, however the reliability may not be precise enough to use on an individual basis. Other shoulder-specific instruments need psychometric testing to compare to the ASES and aid in the formal development of a widely accepted shoulder-specific outcome measure.

 

Patients without shoulder problems: (Sallay, 2003) Study limitations include the use of patients from an outpatient subspecialty practice in the Midwest because it may not be representative of a larger population. The ASES was found to be highly reliable, but age and demographics including attitude, activity level, and general well-being of the patients should be taken into consideration when evaluating posttreatment scores because these things may be related to shoulder function.

 

Shoulder Arthroplasty: (Goldhahn 2008) ASES shoulder form did not disclose any key differences in cross-cultural adaptation process from English to German.  Total score of German ASES demonstrated good reliability/validity that could be utilized following a joint replacement. The instability portion of the measure does not give useful clinical information.
