Official title:
Does the Structural Leg-length Discrepancy Affect the Postural Control? Preliminary Study

Health authority | |
Study type | Interventional |
The structural leg-length inequality caused by the shortening of a segment of an extremity,
results in an altered position of lower limb joints, the pelvis and the spine in static as
well as dynamic conditions. That may induce a disturbance of the postural control.
The objective of this study is to investigate the effect of the structural LLD on the
control of the posture.
