Outcome measures
Primary outcome
1 To measure the activation of the different muscles of the shoulder girdle
during movements, surface and indwelling EMG measurements are taken during
specific movements and tasks.
2 The movements and instructions are simultaneously measured and registered
with 2 camera*s and a microphone
The EMG registration is transferred to a digital database.
Secondary outcome
the following shoulder questionnaire is filled in at home: the Western Ontario
Rotator Cuff Score. For a judgment of the psychological health, the EQ-5 is
taken.
The Constant Murley Score is filled in during the visit
Background summary
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 hoping to find new methods for training
and surgical options.
Study 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.
Study design
a prospective case controlled study
Study burden and risks
Patient may experience some discomfort by performing several movements with
their affect limb. The surface EMG measurements will give no discomfort, the
intra-muscular needle EMG measurements will give some minor discomfort. The
needle EMG measurements will be performed by a trained, experienced research
team. Patients of the control group will have an ultrasonography of the
shoulder with no discomfort or potential hazard. Patients may benefit from the
extra examination as it may give directions for further conservative or
surgical treatment.
