Ultrasling Quadrant Versus Bledsoe ARC Shoulder Brace

Evaluation of Functionality, Operability and Wearing Comfort of Two Multifunctional Shoulder Braces in Patients Who Underwent Shoulder Surgery

Shoulder orthoses are an essential component of both, postoperative care as well as a range of conservative treatment concepts, and thus influence the functional outcome of a wide spectrum of glenohumeral pathologies. Therefore it is important to look at them in greater detail.

A new concept, designed by DJO Global in the "Ultrasling Quadrant®" orthosis now immobilizes only the glenohumeral joint, while giving the possibility of elbow movement. It also allows multiple settings concerning the position of the glenohumeral joint like internal rotation as well as neutral or external rotation. It is yet to be seen how these changes will influence the outcome of therapy as well as how they will change the patient's perception of the orthosis and its wearing comfort. Therefore it is planned to be compared to another multifunctional shoulder brace already established on the domestic and international market, the BledsoeARC® brace.

The primary objective is to assess if one of the investigated shoulder braces Ultrasling Quadrant® or Bledsoe Arc® is perceived by patients who received shoulder surgery as superior in terms of higher wearing comfort when worn during the post-operative immobilization period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall wearing comfort subjectively reported by patients	The primary outcome for this study is the overall level of comfort as perceived subjectively by the patients themselves by a questionnaire (NRS based).	2 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain in ADL	Patients will report subjectively their perceived pain in achieving activities of daily living on an NRS from 0 (no pain) to 10 (maximum pain)	2 weeks
Difficulty	Patients will report subjectively their perceived difficulty in achieving activities of daily living on an NRS from 0 (no difficulty) to 10 (maximum difficulty)	2 weeks
Comfort	Patients will report subjectively their perceived comfort in achieving activities of daily living on an NRS from 0 (no comfort) to 10 (maximum comfort)	2 weeks
Operability	The operability is reported by the level of difficulty of handling of the braces as evaluated subjectively by the patients by a questionnaire on an NRS from 0 (no difficulty) to 10 (maximum difficulty). The patients will also be asked about the total time they wear the brace during the day.	2 weeks
Stability	Stability of the shoulder braces is measured with digital photographs of the braces position at different time points throughout the immobilizing time. The photographs are evaluated digitally with inserted lines that allow angle measurement. The angles of the braces position are then compared to a) the position intended to be immobilized in by the surgeon and b) the position of the brace when being worn by the patient. Differences in the in the application by the patient in comparison to the application by a professional are documented by photographs and measured digitally as well.	2 weeks
Compliance	Patients will be required to wear their allocated brace 24 hours a day/7 days a week, but in clinical practice the PI noted them not sticking to this routine prescription for various reasons. The level of compliance in wearing the braces is an essential information gained by the trial. At weekly intervals patients will be asked to report the mean time their worn the allocated or any other brace during the preceding week (0-6 hours | >6-12 hours | >12-18 hours | >18-24 hours) which allows us to draw conclusions to their compliance. The reason(s) for removing the brace will be documented.	2 weeks
Patient's preference for any of the two braces	At the end of the 4-week immobilization period, patients will be asked about their preference for any of the two braces including an option for undecided patients.	2 weeks
