Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is to investigate the dose-response relationship between load-induced muscle activation (liMA) and load-induced glenohumeral translation (liTr) in patients with rotator cuff tears and asymptomatic control subjects.

Furthermore the study is to investigate the in vivo dose-response relationship between additional weight and glenohumeral translation, to understand the biological variation in liTr, the influence of disease pathology on the liTr, the potential compensation by muscle activation and muscle size, and the influence of liTr on patient outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This project is to test the overall hypothesis that rotator cuff tear affects glenohumeral translation and that this functional instability depends on additional load applied, on anatomical and morphological variations, and on type and severity of the injury. The study is to investigate the dose-response relationship between load-induced muscle activation (liMA) and load-induced glenohumeral translation (liTr) in patients with rotator cuff tears and asymptomatic control subjects.

Furthermore the study is to investigate the in vivo dose-response relationship between additional weight and glenohumeral translation, to understand the biological variation in liTr, the influence of disease pathology on the liTr, the potential compensation by muscle activation and muscle size, and the influence of liTr on patient outcomes.

This study entails cross-sectional experimental multimodal (clinical, biomechanical, radiological) data collection with multiple conditions and a control group.

Intervention Model

PARALLEL

cross-sectional experimental multimodal (clinical, biomechanical, radiological) data collection with multiple conditions and a control group
Primary Study Purpose

DIAGNOSTIC

Blinding Strategy

NONE

Blinding to the experimental condition is not possible because of the obvious differences between conditions (additional load). However, the person processing the data will be blinded to the condition.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1: patient group (unilateral rotator cuff tear)

Group 1: 25 patients with unilateral symptomatic rotator cuff tear

Group Type OTHER

3D motion analysis

Intervention Type DIAGNOSTIC_TEST

30° arm abduction in the scapular plane will be performed with and without a handheld weight of 1, 2, 3, and 4 kg. All movements will be done bilaterally. Electromyographic (EMG) data of arm and trunk muscles will be recorded using surface electrodes. Participants will be asked to perform full arm abduction with different rotations (internal, neutral and external rotation), flexion and internal-/external rotations movements (without additional handheld weight).

isometric shoulder strength by dynamometer

Intervention Type DIAGNOSTIC_TEST

isometric shoulder strength for abduction and internal/external rotation will be assessed with a isometric shoulder strength for abduction and internal/external rotation will be assessed with a dynamometer

fluoroscopic images of each shoulder

Intervention Type DIAGNOSTIC_TEST

fluoroscopic images (Multitom Rax, Siemens Healthineers, Erlangen, Germany) of each shoulder will be taken during the 30° arm abduction test with and without a handheld weight (0, 2, and 4kg)

Bilateral shoulder Magnetic Resonance Imaging (MRI)

Intervention Type DIAGNOSTIC_TEST

MRI of both shoulders will be taken
