Clinical Trial Summary

The purpose of this study is to determine the ability of a mobile clinical application to reliably and accurately track scapular motion in people with asymptomatic and symptomatic shoulders. The ability to accurately and reliably measure shoulder position clinically is an important first step in choosing the best treatment techniques to treat shoulder movement dysfunction. Therefore, the primary objectives of the study are:

1. To determine the inter- and intra-rater reliability of shoulder joint position measurements in symptomatic and asymptomatic subjects, by using a mobile application, with and without use of a handle for a smartphone

2. To determine the validity of the shoulder joint position measurements measurements as described above.

Description:

Subjects will be asked to provide demographic and background information such as age, height, history of pain or injury, and descriptions of their physical activity levels. Subjects will receive a clinical screening exam by a licensed physical therapist to determine the type of movement abnormalities present, the severity of their symptoms and to screen for inclusion and exclusion criteria.

To collect scapular position measurement reliability data, subjects will stand through out data collection. Measurements of the scapula will be taken with the mobile application for the arm at rest and in two elevated position. Subjects will wear an off-the-shelf elbow brace when asked to hold their arm in the two elevated positions. These elevated positions will be maintained by having subjects maintain contact of their forearm against a guide. For intra-rater reliability, position measurements will be repeated twice for each of three planes of elevation. Additionally, for inter-rater reliability each measurement will be repeated once by two other examiners. This process will repeated twice when using the application with and without the handle.

For the validation portion of the study, a subgroup of subjects will have the same position measurements performed by a single examiner with additional motion sensors taped to the skin of their scapula and breast bone and a sensor attached to an arm brace strapped to their arm.

In total, the subject will be asked to raise and hold their arm for approximately 5 sec, 36 times during the testing within ranges of motion typically performed during daily activities.
