Outcome measures
Primary outcome
2 sets of EMG measurements will be taken while performing isometric and shoulder specific movements.
Secondary outcome
The objective and subjective shoulder function will also be evaluated by using specific shoulder and pain tests and questionnaires.
Background summary
Rationale: Patients with a rotator cuff tear have a different movement pattern and this eventually can lead to a pseudo paralysis. First it starts with alterations in muscle activation without effect on shoulder movement. Some studies are done to investigate the function of the remaining attached muscles, but most are not related to the movement of the shoulder. Also no control group, matched for age, with an intact rotator cuff was used. There is an indication that the long head biceps tendon has an important function as it is the remaining structure preventing the humeral head to migrate superiorly if the rotator cuff is torn. We try to investigate the effect of a cuff rupture on the remaining shoulder muscles in the older patient. Thereby it is hoped to find new methods for training and surgical options.
Objective: To compare the shoulder muscle activation and movements in patients having a rotator cuff tear with subjects, matched for age, with no cuff tear.
Secondary, within the group of patients with a rotator cuff tear, we will compare the shoulder muscle activation in patients with a massive rotator cuff tear (MRCT) with and without a pseudo paralysis.
Study design: a prospective case controlled study
Study population: Patients with a degenerative cuff tear (retraction Patte stage 2 or 3) confirmed on sonography or MRI. A control group is matched as a group on age with no cuff tear on sonography. A MRCT is defined as a 2 or 3 tendon rotator cuff tear or a tear with a diameter of > 5 cm. A pseudo paralysis is defined as being not able to abduct to 90 degrees.
Main study parameters:
2 sets of EMG measurements will be taken while performing isometric and shoulder specific movements.
Secondary parameters:
The objective and subjective shoulder function will also be evaluated by using specific shoulder and pain tests and questionnaires.
Also the health related quality of life is measured as it can influence the outcome.
Study objective
shoulder muscle activation and movements in patients having a rotator cuff tear is affected compared to healthy volunteers, matched for age, with no cuff tear.
Study design
all measeruments are done bij 1st of October
