Investigating the multifactorial etiology of supraspinatus tendon tears Open
The purpose of this study was to develop a multivariable model to determine the extent to which a combination of etiological factors is associated with supraspinatus tendon tears. Fifty‐four asymptomatic individuals (55 ± 4 years) underwen…

In vivo evaluation of rotator cuff internal impingement during scapular plane abduction in asymptomatic individuals Open
Internal impingement—or entrapment of the undersurface of the rotator cuff tendon against the glenoid during overhead activities—is believed to contribute to articular‐sided tears. However, little is known about internal impingement outsid…

In Vivo Static Retraction and Dynamic Elongation of Rotator Cuff Repair Tissue After Surgical Repair: A Preliminary Analysis at 3 Months Open
Background: Rotator cuff repair is a common orthopaedic procedure that provides pain relief for many patients, but unfortunately, an estimated 20% to 70% of repair procedures will fail. Previous research has shown that elongation (ie, retr…

Measuring 3D In-vivo Shoulder Kinematics using Biplanar Videoradiography Open
The shoulder is one of the human body's most complex joint systems, with motion occurring through the coordinated actions of four individual joints, multiple ligaments, and approximately 20 muscles. Unfortunately, shoulder pathologies (e.g…

Ultrasound shear wave elastography and its association with rotator cuff tear characteristics Open
Although ultrasound SWE measurements have been shown to be altered in the presence of various tendinopathies, the findings of this study suggest the utility of ultrasound SWE in this population (ie, patients with a small to medium supraspi…

Variability of glenohumeral positioning and bone-to-tendon marker length measurements in repaired rotator cuffs from longitudinal computed tomographic imaging Open
Apparent tendon retraction of 5 mm or more, when measured as the distance from a tendon marker's day of surgery location to its new location on a volumetrically registered longitudinal CT scan, may be considered above the usual range of me…

Dynamic foraminal dimensions during neck motion 6.5 years after fusion and artificial disc replacement Open
Changes were observed in the range of foraminal geometry at adjacent levels from 2 years to 6.5 years post-surgery that were different between ACDF and ADR for neck extension. These changes are contrary to the notion that motion at adjacen…

Correlation of neural foraminal motion after surgical treatment of cervical radiculopathy with long-term patient reported outcomes Open
Dynamic 3D foraminal dimensions at 2-year post-surgery, notably FW.Min measured in neck extension at adjacent levels, were associated with PRO at 6.5 years post-surgery. These relationships provide insight into the motion related factors i…

Clinical utilization of shear wave elastography in the musculoskeletal system Open
Shear wave elastography (SWE) is an emerging technology that provides information about the inherent elasticity of tissues by producing an acoustic radiofrequency force impulse, sometimes called an "acoustic wind," which generates transver…

Association Between Years of Competition and Shoulder Function in Collegiate Swimmers Open
Background: Shoulder injuries are common among competitive swimmers, and the progression of shoulder pathology is not well understood. The objective of this study was to assess the extent to which years of competitive swim training were as…
View article: Effects of age and pathology on shear wave speed of the human rotator cuff
Effects of age and pathology on shear wave speed of the human rotator cuff Open
Rotator cuff tears are common and often repaired surgically, but post‐operative repair tissue healing, and shoulder function can be unpredictable. Tear chronicity is believed to influence clinical outcomes, but conventional clinical approa…

Effects of Rotator Cuff Pathology and Physical Therapy on In Vivo Shoulder Motion and Clinical Outcomes in Patients With a Symptomatic Full-Thickness Rotator Cuff Tear Open
Background: Physical therapy (PT) is often prescribed for patients with rotator cuff tears. The extent to which PT influences strength, range of motion (ROM), and patient-reported outcomes has been studied extensively, but the effect of PT…
