“…Measurement of the SsT thickness and AHD were undertaken according to a previously published reliable protocol, with minimal detectable difference (MDD) values of 0.7 mm for AHD and 0.6 mm for SsT thickness. 18 For the AHD measures, the participant was sitting, shoulder neutral, with the hand resting on the lap. An ultrasound image was taken with the transducer positioned along the line of the humerus, over the anterior part of the acromion, with the subacromial space and humeral head visible.…”

Background/aimExercise imparts a load on tendon tissue that leads to changes in tendon properties. Studies suggest that loading immediately reduces tendon thickness, with a loss of this response in symptomatic tendinopathy. No studies investigating the response of tendon dimensions to load for the rotator cuff tendons exist. This study aimed to examine the short-term effect of loading on the thickness of the supraspinatus tendon and acromiohumeral distance those with and without rotator cuff tendinopathy.MethodsParticipants were 20 painfree controls, and 23 people with painful rotator cuff tendinopathy. Supraspinatus tendon thickness and acromiohumeral distance were measured using ultrasound scans before, and at three time points after loading (1, 6 and 24 hours). Loading involved isokinetic eccentric and concentric external rotation and abduction.ResultsThere was a significant increase in supraspinatus tendon thickness in the pain group at 1 (7%, ∆=0.38, 95% CI 0.19 to 0.57) and 6 hours (11%, ∆=0.53, 95% CI 0.34 to 0.71), although only the 6 hours difference exceeded minimal detectable difference. In contrast, there was a small non-significant reduction in thickness in controls. The acromiohumeral distance reduced significantly in both groups at 1 hour (controls: ∆=0.64, 95% CI 0.38 to 0.90; pain: ∆=1.1, 95% CI 0.85 to 1.33), with a larger change from baseline in the pain group.ConclusionThose diagnosed with painful supraspinatus tendinopathy demonstrated increased thickening with delayed return to baseline following loading. Rehabilitation professionals may need to take into account the impact of loading to fatigue when planning rehabilitation programmes.

“…A convenience sample of 73 patients with chronic, unilateral shoulder pain of their dominant arm were recruited from three different primary care centres. General practitioners (GPs) carried out the recruitment and research assistants screened all participants for eligibility, with a final sample size of 62 participants obtained after applying the following inclusion criteria: i) positive Neer test; ii) positive Hawkins-Kennedy test; iii) positive Jobe test; iv) positive Speed test; v) positive Gerber test; vi) painful arc present during flexion or abduction; vii) pain during resisted lateral rotation and/or abduction; viii)and a focal hypoechoic zone within the substance of the rotator interval tendons and/or small hypoechoic discontinuities of the internal or external surfaces of these tendons, without swelling image (McCreesh et al, 2015).…”

“…Patients with shoulder impingement syndrome have shoulder pain particularly during arm elevation which may be caused by a narrowing of acromiohumeral distance. 3,4 Provocative tests such as the Neer and Hawkins test aim to compress the soft tissue between the tuberculum major and the coracoacromial arch, and thereby narrowing the acromiohumeral distance. Therefore, characterizing subacromial dimensions such as acromiohumeral distance and the supraspinatus tendon thickness may enhance the understanding of the underlying mechanisms of shoulder impingement syndrome and support the diagnosis.…”

Objectives: This study aims to evaluate the intra-and inter-rater reliability coefficients of the supraspinatus tendon thickness, acromiohumeral distance, and occupation ratio in patients with shoulder impingement syndrome. Patients and methods: The study included 83 patients (21 males, 62 females; mean age 51.6±11.0 years; range, 26 to 70 years) with shoulder impingement syndrome. The supraspinatus tendon thickness, acromiohumeral distance, and occupation ratio values were obtained one week apart by two observers. The intraclass correlation coefficient (ICC), minimum detectable change, and standard error of measurement were calculated. Results: The first observer had excellent intra-rater reliability in all measurements (ICC >0.90) with minimum detectable change of 0.740-0.047 mm and standard error of measurement of 0.017-0.26 mm. The second observer had excellent intra-rater reliability in supraspinatus tendon thickness and acromiohumeral distance measurements (ICC >0.90) with minimum detectable change of 0.498-0.770 mm and standard error of measurement of 0.18-0.28 mm and good intra-rater reliability in the occupation ratio measurement (ICC; 0.75-0.90) with minimum detectable change of 0.060 mm and standard error of measurement of 0.022 mm. Inter-rater reliability coefficients were 0.916 (95% confidence interval [CI]; 0.873-0.945) for supraspinatus tendon thickness, 0.943 (95% CI; 0.914-0.963) for acromiohumeral distance with minimum detectable change of 0.673 mm and standard error of measurement of 0.243 mm and 0.790 (%95 CI; 0.693-0.853) for occupation ratio with minimum detectable change of 0.077 mm and standard error of measurement of 0.028 mm. Conclusion: These findings suggest that ultrasonographic measurements of the supraspinatus tendon thickness, acromiohumeral distance and occupation ratio can be reliable and consistent for clinical evaluation of patients with shoulder impingement syndrome in terms of supporting diagnosis and monitoring the treatment effect.
