“…This is in agreement with previous studies on healthy individuals [2,7,9] that have reported that RTUS is a reliable method. However, Previous studies have reported acromiohumeral distances, but used different modalities such as radiography, magnetic resonance imaging and in vitro measures.…”

“…Published studies [7][8][9][10] have investigated the reliability of clinically available methods to measure and evaluate the habitual humeral head position in relation to scapular landmarks to help in diagnosis and treatment of shoulder pathology. These studies all have potential limitations in the way the humeral head position was measured: they lack sufficient rigor in their measurement properties, such as imprecise description of landmarks and transducer placement [7] and small sample sizes [8][9][10].…”

“…These studies all have potential limitations in the way the humeral head position was measured: they lack sufficient rigor in their measurement properties, such as imprecise description of landmarks and transducer placement [7] and small sample sizes [8][9][10]. This suggests that further investigation is necessary, as to date; there have been no protocols which have been developed to evaluate the reliability of RTUS scanning to measure glenohumeral joint position and function.…”

The aim of the current study is to assess the intra-rater and inter-rater reliability of real time ultrasound scanning in measuring static humeral head position. Real time ultrasound scanning, an experimental clinical measurement, was used to record measurements of the humeral head position in a sample of (20) healthy volunteers [9 male, 11 female]. While the participant was seated in a standardized chair, Hips and knees were positioned at 90 degrees of flexion. The humeral head position of each subject was imaged at three ultrasound view [anterior, posterior and superior] in a different arm positions; images were repeated three times for each position by the same examiner on the same day to assess Intra-rater reliability. The Images were then analysed by the researcher and a second investigator to assess inter-tester reliability. Intra-rater and inter-rater reliability were quantified by using the intraclass correlation coefficient and standard error of measurement, the smallest detectable difference values were calculated and were used to estimate the magnitude of change that is predictable to exceed measurement error. The intra-rater reliability for all positions was found to be excellent for all tests ranged from 0.83 to 0.99 respectively. Inter -rater reliability between examiners was found to be good to excellent for all test positions ranged from 0.66 to 0.98, and the standard error of measurement for all positions was less than the calculated mean. This study demonstrates that real time ultrasound scanning is a reliable method of assessing the location of the humeral head in a number of arm positions in healthy subjects when measured by the same examiner and this may suggest that RTUS could be used to assess the impact of rehabilitation programme or surgical interventions for shoulder pathology.

“…Our results are comparable to a recent reliability study of AHD measured on ultrasound images of patients with RCD, with reported reliability of 0.92 and 0.90 at rest and 60° abduction, respectively. 29 There was no effect of the presence or absence of RCD on AHD across postures and arm angles. Subjects in the RCD group represented the broad spectrum of the disease as identified by their MRI, ranging from impingement syndrome to partial-thickness and full-thickness rotator cuff tear.…”

“…We measured AHD at 608 of shoulder abduction, as acoustic shadows might occur in higher ranges of shoulder abduction, 26,27 and US measurement of AHD at 608 of shoulder abduction has shown excellent reliability in asymptomatic individuals 27 and patients with subacromial impingement syndrome. 28 The transducer was placed on the lateral surface of the acromion in the coronal plane and was parallel with the long axis of the humerus, where the shortest distance between the humerus and acromion was observed. During the US measurements, we instructed participants to rest their upper extremity on the pillow and visually inspected to ensure that they elevated or abducted their shoulder (Figure).…”

Objective: To investigate shoulder-rotator strength, internalrotation (IR) and external-rotation (ER) range of motion (ROM), and acromiohumeral distance (AHD) in asymptomatic adolescent volleyball attackers to determine if they have risk factors for injury.Design: Cross-sectional study. Setting: University laboratory. Participants: Thirty-nine adolescent high school-aged volleyball attackers (22 boys, 17 girls; age ¼ 16.0 6 1.4 years, height ¼ 179.2 6 9.0 cm, mass ¼ 67.1 6 10.9 kg, body mass index ¼ 20.7 6 2.6 kg/m 2 ). Main Outcome Measure(s): Shoulder IR and ER ROM, total-rotation ROM, glenohumeral IR deficit, AHD, and concentric and eccentric strength of the shoulder internal and external rotators were tested bilaterally.Results: External-rotation ROM was greater (t 38 ¼ 4.92, P , .001), but IR ROM (t 38 ¼ À8.61, P , .001) and total ROM (t 38 ¼ À3.55, P ¼ .01) were less in the dominant shoulder, and 15 athletes had a glenohumeral IR deficit (IR ROM loss . 188). We observed greater concentric internal-rotator (t 38 ¼ 2.89, P ¼ .006) and eccentric external-rotator (t 38 ¼ 2.65, P ¼ .01) strength in the dominant than in the nondominant shoulder. The AHD was less in the dominant shoulder (t 38 ¼ À3.60, P , .001).Conclusions: Adolescent volleyball attackers demonstrated decreased IR ROM, total ROM, and AHD and increased ER ROM in their dominant shoulder. Therefore, routine screening of adolescent athletes and designing training programs for hazardous adaptive changes could be important in preventing shoulder injuries.Key Words: ultrasonography, sports, glenohumeral joint, muscle strength Key PointsAsymptomatic adolescent volleyball attackers demonstrated less internal-rotation range of motion (ROM), total ROM, and acromiohumeral distance and more external-rotation ROM in the dominant than in the nondominant shoulder, which might put them at risk for shoulder injuries. Routinely screening adolescent athletes and designing training programs to address hazardous adaptive changes could help prevent shoulder injuries.

Reliability study of the sonographic measurement of the acromiohumeral distance in symptomatic patients

Abstract: The inaccuracy of the method was 1 mm regardless of the experience of the observer. US AHD measurement in patients with shoulder complaints is not as accurate as reported in healthy subjects. This may have important implications for the clinical use of this parameter.
