Brief Summary

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.

Conditions

Leg Length Inequality

Outcome Measures

Primary Outcomes (1)

• Evaluation of mean COP velocity in anteroposterior and mediolateral directions during stance in subjects

  Mean COP velocity \[mm/s\] is recorded in anteroposterior (AP) and mediolateral (ML) directions within posturographic evaluation in examination of every participant.

Secondary Outcomes (1)

• Evaluation of weight distribution during stance in subjects

Study Arms (2)

Individuals with leg-length discrepancy

EXPERIMENTAL

Patients of Department of Paediatric Orthopaedics and Traumatology, Poznan University of Medical Sciences diagnosed with leg-length discrepancy. The examination of participants included a measurement of the length of lower limbs and the weight distribution as well as performing the static posturography.

Other: static posturography

control group

ACTIVE COMPARATOR

The group with healthy individuals; without leg-length discrepancy. The examination of participants included a measurement of the weight distribution as well as performing the static posturography.

Other: static posturography

Interventions

static posturography OTHER

The measurement of the weight distribution and the static posturography was performed on the balance platform Good Balance by Metitur . The device is comprised of the triangular force platform with electronic system and computer software. The body weight distribution was evaluated in the upright standing with eyes open, feet placed 20 cm from each other.The individual stood motionlessly for 15 s, then the measurement was recorded. The static posturography was performed with 3 various positions of feet, both with eyes open and eyes closed. (1) Position : normal standing - an upright standing with feet placed parallel 20 cm apart for 30 s. (2) Position: tandem - a stance with one foot placed ahead of the other. for 20 s. (3) Position: one leg standing: stance on the one leg for 20 s.
