About

Taking and moving objects is essential. When this becomes difficult, it affects daily functioning. This study aims to determine movement patterns, at the level of the shoulder, during different functional movements in elderly people aged 60 years and older. Movement patterns of people without shoulder problems and patients with a reverse shoulder prosthesis will be compared. These insights can contribute to improving functional rehabilitation in patients with a reverse shoulder prosthesis (RSA).

Full description

This study aims to investigate how elderly people (60 years and older) without shoulder pain and patients with a reverse shoulder arthroplasty (60 years and older) perform functional reaching movements. Using IMUs (Inertial Measurement Units), the investigators want to look at mode of execution, relational positions of hand, elbow and shoulder in space, in relation to the trunk and each other, and any compensatory movements made by patients with a reverse shoulder arthroplasty.

At the time of testing, participants will first complete a series of questionnaires. These questionnaires will provide information about the daily functioning of all participants. The participants' shoulder strength will also be measured.

After applying the IMUs, the participant will first perform a maximal movement (active for participant) in 4 directions (forward and lateral lifting of arm, hand-to-neck , hand-to-back). Then the researcher will perform the same movements with the participant's arm (passive for participant). This will allow measurement of the maximum active and passive mobility of the shoulder. Next, the participant will be asked to place and take back a number of different objects (both in terms of size and weight) at predetermined heights.

The participants without shoulder pain will be tested once, the participants with a reverse shoulder arthroplasty we want to test 4 times. The participants without shoulder pain will be assigned to the control group. The participants with a reverse shoulder arthroplasty we want to test 4 times to monitor not only their movement pattern, but also any changes in this pattern .

The questionnaires, strength measurement and requested movements will be the same for both groups.

Analysis of these movements will provide us with insights that can help improve the functional rehabilitation of patients with a reverse shoulder prosthesis.

All participants with a reverse shoulder arthroplasty will be recruited at UZ, participants without shoulder pain will be recruited through different channels (these are not patients)
