In-Depth Information
- mean standard deviations calculated over 10 cycles of
the movement carried out byeach subject (giving the
reproducibility of the same movement for the given subject):
SD1;
- standard deviation of maximum amplitudes measured
over all subjects (giving the variability of these maximum
amplitudes for a single movement): SD2.
5.3.2.
Results and discussion
The mean amplitudes (expressed in degrees), different
standard deviations (expressed in degrees and as a
percentage), the minimum and maximum amplitudes
(expressed in degrees) for each simple movement (flexion-
extension, right and left lateral bending and right and left
rotation) are presented in Table 5.1.
