“…However, the inter-observer differences for the Constant score of two observers were higher in two other studies. In one study, the 95% confidence limits for a single assessment was 16 to 20 points [47] and, in another study, 50% of the differences between two observers were between 10 and 25 points [48]. Conboy et al concluded that such differences make the Constant score insufficiently reliable for clinical follow-up studies [47].…”

Abstract:The objective was to identify whether arthroplasty or conservative treatment is the best available treatment for three-and four-part proximal humeral fractures by analyzing the outcome measure of the Constant score. We conducted an electronic search. The systematic review included 33 studies encompassing 1096 patients with three-or four-part proximal humeral fractures that used the Constant score as outcome measure. The mean Constant score in the conservative group was 66.5 and in the arthroplasty group was 55.5. The difference could be attributed to selection bias, unreliable classification of the fractures and inter-observer differences in the assessment of the Constant score.

“…6 Still, the test has met substantial criticism of its reliability and validity. 15,16 The psychometric properties of the CMS were recently systematically reviewed. 16 Although evidence was found to support the use of the CMS, several aspects of the methodological properties of the CMS have not been adequately evaluated.…”

“…The median length of the right and left arms measured from the acromion to the distal radius at the joint line (lever arm) was 54 cm (range, 42-64 cm). The median body weight and height were 72 kg (range, 45-125 kg) and 173 cm (range, 158-203 cm), respectively, with a median BMI of 23 (range, [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]). An abbreviated self-assessment CMS test [3,26] was completed by the volunteers, which indicated no shoulder complaints, with every volunteer scoring the maximum of 75 points on a scale from 0 to 75.…”

“…Various studies have affirmed good reproducibility, responsiveness, and construct validity [1-3, 5, 8, 9, 17, 25, 30, 31] of the score, but they did not assess content validity and internal consistency. Rocourt et al [28] reported how internationally used Constant-Murley shoulder assessment protocols varied widely regarding several procedural details, and therefore they decided to use the original description as published by Constant and Murley in 1987 [10]. Strength measurement represents 1 . 4 of the CMS.…”

Reports using the Constant-Murley score often lack details regarding how strength measurement was performed, which may have an important impact on the results obtained. A description of the measurement is especially important when patients are unable to adopt the prescribed position of 90 degrees shoulder abduction, leading to invalid or highly discrepant scores. We investigated the influence of shoulder abduction and torso position on strength measurement with special emphasis on intraobserver reliability. Thirty-three healthy volunteers were examined using a handheld dynamometer (Isobex) in 30 degrees , 60 degrees , and 90 degrees abduction with or without stabilization of the torso. A linear correlation between strength measurements in different degrees of abduction was observed, with values at 90 degrees abduction on average 15% lower than at 60 degrees and 45% lower than at 30 degrees . In multivariate analysis, gender and weight had a substantial impact on the strength of individual measurement positions. Intraobserver reliability was related to arm and torso position (intraclass correlation coefficients, 0.71-0.93) and was highest for 90 degrees abduction without torso stabilization. These findings emphasize the importance of standardized torso and arm positions ensuring high reliability when performing the strength measurement of the Constant-Murley score.
