Study Design

Intervention model single group assignment
Masking open label
Primary purpose treatment
Grade I, II and III manual mobilizations in the inferior, posterior and distractive directions.
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.

Primary Outcomes

Movement of the humeral head
time frame: Immediate measurement of humeral head movement concurrent with application of manual mobilization

Secondary Outcomes

Force of Mobilization
time frame: Immediate measurement of force used during the application of manual mobilization

Eligibility Criteria

Male or female participants from 18 years up to 65 years old.

Inclusion Criteria: - asymptomatic subjects with no history of neck, shoulder, or arm pain; full active pain free range of motion at the cervical spine and shoulders Exclusion Criteria: - neuromuscular or musculoskeletal disorders; connective tissue disorders such as rheumatoid arthritis; inflammatory conditions such as Crohns disease; Down's syndrome; Marfan's syndrome; medically diagnosed hypermobility; history of neck, shoulder or arm trauma, pain, or surgery including dislocation and rotator cuff tears; pregnancy; and metal implants

Additional Information

Official title Rehabilitative Ultrasound Imaging: Measurements of Articular Movement of the Shoulder
Principal investigator Dexter Witt, DHS
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.
