Summary

The purpose of this study is to measure the amount of movement between the bones of the shoulder joint when mobilization techniques are applied by a physical therapist.

Detailed description

The purpose of this study is to image the articular joint movement of the glenohumeral joint utilizing ultrasound imaging (USI). Specific aims include: 1) measurement of the distance between the articular surfaces at rest; 2) measurement of the distance between the articular surfaces during manually applied glides of those surfaces; and 3) analysis of any association between the amount of glide and reported joint mobility, force application, or joint position. Subjects will be recruited from a population of convenience. After consenting to participate, eligible subjects will complete a demographic questionnaire and pretesting of scapular and shoulder mobility. Two days of testing will be scheduled. On the first day, three grades of glenohumeral mobilization will be applied in the following directions: distraction, posterior and inferior. A handheld dynamometer will measure force; ultrasound imaging will record glenohumeral joint position. Each grade and direction will be repeated three times on the right and the left shoulder. On the second day, the mobilizations will be repeated. Measurements of humeral movement will be calculated from the ultrasound images.

• Disorder of Shoulder

Interventions

Type	Name	Description
DEVICE	Manual Mobilization	Stabilization of the glenoid fossa with movement of the humerus using varying degrees of force as applied by a physical therapist. Subject is positioned with the shoulder in 55 degrees of abduction and 30 degrees of horizontal adduction. Manual force is applied by a physical therapist on the proximal humeral head moving the humeral head posterior, inferior or lateral (distraction). An ultrasound transducer placed over the anterior shoulder joint provides imaging of the humeral head and the glenoid fossa. This manual intervention is repeated three times in each direction on each arm.
