The effect of stabilization and conscious control training on clavicular kinematic in females with scapular dyskinesis

Previous studies showed that alteration in scapular kinematic may cause changes in clavicle and shoulder and
finally lead to disorders in the upper quarter. To expand treatment options for patients with forwarding head and shoulder posture, this
study investigated the effects of scapular stabilization and conscious control training on clavicle selected kinematic variables in
Materials & Methods: in this semi-experimental study, forty-four female subjects with scapula dyskinesis (inferior angle & medial
border pattern) were randomly assigned to 3 groups: stabilization (n=15), conscious control (n=15) and control (n=14). All the subjects
were tested (i.e., a pre-test and a post-test) for investigating the degree of disorder in the clavicular kinematic (using motion analysis
system). Then, the subjects in scapular stabilization and conscious control were trained three days a week for six weeks (45 minutes
for each session). The paired t-test and analysis of covariance were used for statistical analysis.
Result: There were significant within-group changes in angle of clavicle (90 degrees) in the conscious group (p=0.028) but no
significant differences were observed in stabilization and control groups. There were significant differences between conscious and
stabilization study groups, but only conscious group demonstrated significant differences when compared to the control and
stabilization groups. No significant changes were observed for other degrees (p>0.05).
Conclusion: The findings of the present study supports the effectiveness of conscious exercise-therapy in improving clavicular
kinematic. Based on the data average changes in pre-test and post-test of both groups, it can be claimed that conscious control and
stabilization protocol training improves the orientation and motion of the clavicle in patients with scapular dyskinesis. The use of
scapular conscious control and stabilization training along with other exercise-therapy protocols of shoulder complex is suggested for
improving scapular and clavicular kinematic in patients with scapular dyskinesis
