Attach the adapter to the dynamometer by sliding it in the input arm from the top.
Ask the subject to lay on the positioning chair or seat on the chair.
Ask the subject to hold the grip and position the forearm in the stabilizer. Tighten the strap. Adjust
the stabilizer-hand grip distance.
Set the axis of the joint rotation. To achieve the alignment make sure the forearm is parallel to the
dynamometer input adaptor. To succeed the alignment you might need to make alterations to the
positions of the chair and the dynamometer.
Be careful not to lose the 90° abduction angle of the shoulder, while trying to achieve the alignment.
Use a goniometer to check the angle.
Check the axis of rotation by asking your subject to perform an internal rotation followed by an
external one.
Opposite Side
Release your subject's forearm by unstrapping the stabilizer's belt. Instruct your subject to stop
handling the grip.
While the subject still lays on the chair, slide the chair away from the dynamometer.
Adjust the chair and the dynamometer to align the dynamometer axis with the joint rotation axis
Follow the steps 6 -8 as described above.
