Outcome measures
Primary outcome
The primary outcome measures of the first objective are the shoulder torque and
shoulder power production during functional tasks, and the associated joint
angular velocity, during performance of the ADL tasks. The ratio between
eccentric and concentric torque will be analysed. Also the maximal isokinetic
muscle strength, recorded by the KinCom dynamometer will be used.
Pain during the measurements will be checked. Between the different KinCom
measurements, the participants will be asked to fill out the Visual Analogue
Scale, to check if he/she experiences pain, and if he does how much pain he
experiences.
For the second objective, the shoulder joint angles (active range of
flexion/extension, abduction/adduction in frontal plane, internal/external
rotation) during functional tasks and the isometric shoulder muscle strength
(in terms torque) will be investigated.
The SF-36 health survey questionnaire (SF-36) measures the physical health
(physical functioning, role-physical, bodily pain and general health) and the
mental health (Vitality, Social functioning, role-emotional, mental health).
For each domain a sub-score will be calculated, and the total score indicates
the overall health.
For measuring the experienced pain and problems in the shoulder joint during
daily activities, the shoulder disability questionnaire will be filled out
(27). This is a questionnaire that measures the sub-domains pain and
restrictions in activities. The items are scored on a VAS scale, and the total
score will be between 0 and 100.
Pain during the measurements will be checked. Between the different KinCom
measurements, the participants will be asked to fill out the Visual Analogue
Scale, to check if he/she experiences pain, and if he does how much pain he
experiences.

Background summary
Previous research has shown that elderly above the age of 55, are more likely
to develop shoulder problems than younger adults. Moreover healthy elderly also
have restrictions compared with young adults. The most common shoulder
complaint amongst elderly is subacromial pain syndrome (SAPS), which can lead
to pain and difficulties performing activities of daily living (ADL).
Identifying the limited activities that need extra support in patients with
SAPS would be very helpful for diagnostic and rehabilitation purposes.
These limitations while performing ADL could be a consequence of pain but also
of a decrease in range of motion (ROM) and torque production. Torque is a
result of muscular, ligament and friction forces acting to change the angular
rotation of a joint. It is known that torque production is diminished with an
increased angular velocity (velocity of joint movement). More information about
the exact extent of these impairments could help clinicians develop an exercise
program to reduce limitations in torque and range of motion and to maintain a
good quality of life.
Available literature often reports on the maximal ROM or torque production.
However, the maximal range is often not necessary to perform ADL. Therefore it
would be relevant to measure the changes in shoulder ROM and torque production
while functional activities are performed. In this study we propose to measure
young adults, healthy elderly and elderly with SAPS to identify and distinguish
between age-related changes in shoulder function and changes associated with
SAPS. On the basis of this study it could become possible to identify the
limiting underlying mechanism in the performance of ADL in both healthy elderly
and elderly with SAPS.
Study objective
This study has two objectives:
(1) To determine the influence of joint angular velocity on torque production
in the shoulder joint during functional movements in young adults, healthy
elderly and elderly with subacromial pain syndrome.
(2) To determine the relationship between range of motion measured during
functional movements and the maximal isometric muscle strength in young adults,
healthy elderly and elderly with subacromial pain syndrome.
Study design
This pilot study consists of a cross sectional design with three different
groups.
Study burden and risks
The KinCom equipment is set to the abilities of each patient, which means that
the range of measurement of the equipment is set within the pain-free area of
motion. To protect the participants during the measurements, the KinCom
dynamometer is supplied with mechanical stops and safety belts, to prevent
exceeding the range of movement and protect the patient from falling.
Furthermore the KinCom dynamometer has an emergency stop, which the participant
can use in case of an emergency/discomfort. With this emergency stop, the
participant can immediately stop the movement of the KinCom. The measurements
with the KinCom dynamometer are within the range of the activities that need to
be performed during daily living.
During the measurements with the Optotrak motion capture system, markers will
be attached with tape on the skin. Removing the markers after the measurements
may result in temporary local irritation of the skin. There are no other risks
that are larger than during daily live.
