The aim of the current study is to provide a reliable objective parameter to indicate an anterior translation of the humeral head during movements of the arm, suggestion a motor control deficit of the rotator cuff.

Outcome measures
Primary outcome
Evaluate the glenohumeral joint translation in the instable shoulder compared
with the stable shoulder of a healthy control group during external rotation of
the arm.
Secondary outcome
Evaluate the glenohumeral joint translation in the instable shoulder compared
with the stable shoulder of a healthy control group during extension of the
elbow.
Evaluate the inter rater- and intra rater reliability of the ultrasound guided
HHCT.
Evaluate the subjective function and stability of the instable shoulder.
Evaluate the objective stability of the instable shoulder.
Evaluate the association between the results of the apprehension test and HHCT.
Evaluate the effect of twelve weeks of motor control training using the HHCT.
Background summary
After the initial dislocation recurrent instability has been reported in 19-46%
of the patients and patient characteristics, bony- and labral lesions as well
as motor control deficiency have been reported as factors related to
recurrence. The choice of approach to restore stability of the glenohumeral
joint is based on patient characteristics as age, gender, sport type and
intensity and (bipolar) bone loss. Leaving us with a paucity concerning the
dynamic stability of the glenohumeral joint in this decision making process.
The standard procedure for imaging laxity of the glenohumeral joint is static
stress radiography. However several studies suggest that the use of dynamic
ultrasound may also be a valid method for assessing laxity of the shoulder
Study objective
The aim of the current study is to provide a reliable objective parameter to
indicate an anterior translation of the humeral head during movements of the
arm, suggestion a motor control deficit of the rotator cuff.
Study design
Case-control study
Intervention
Twelve weeks exercise program consisting of stabilizing exercises.
Study burden and risks
The benefits will primarily be to society, as we will learn more about the
results of the HHCT in the evaluation of treatment of shoulder instability.
This group of patients who experience recurrent instability is the only
population that can provide the answers to our research questions.
The burden and risk associated with returning to the Jan van Goyen Medical
Center for physical examination can be considered low. Only the ultrasound
assessment executed by the (second observer) radiologist and the evaluating
ultrasound after twelve weeks are not part of usual care and can be seen as an
extra burden.
There is no risk associated with the ultrasound assessment. These additional
ultrasound assessments will be completed in 30 minutes and will be combined
with the second and a final visit to the center.
