Rotation sequence recommended by
the ISB for the glenohumeral joint
Van Andel
et al.
[VAN 08] report the maximal active joint
amplitudes (ranges of motion) and the evolution of angles of
different joints of the upper limb for 10 healthy subjects
during the execution of several functional tasks: touching the
contralateral shoulder with their hand, putting their hand to
their mouth, brushing their hair and putting their hand in
their back trouser pocket. For this, the protocol used is based
on the ISB recommendations except for movements of the
shoulder, given the difficulties we have just described. For
this joint, the joint angles of the shoulder complex are
assessed as a whole (by considering the motion between the
arm and the thorax) and this information is also
complemented by reporting the joint angles of the movement
of the scapula with regard to the thorax. The intra- and
inter-session reliability of this protocol has been assessed for
10 healthy children [JAS 11b], as well as for 12 children
suffering from cerebral palsy [JAS 11b] aged between 6 and
15 years old. The comparisons of results obtained for 20
children suffering from cerebral palsy with the control group
of 20 healthy children of the same age [JAS 11a] confirmed
that the duration of movements were longer and the
trajectories were less direct in unhealthy children, which
