Idiopathic scoliosis patients have postural equilibrium problems.
The objective of this study was to assess postural control in subjects
with idiopathic scoliosis following a 4-month intervention in an unbraced position.
STUDY DESIGN:
Quasi-experimental. METHODS:
Eight healthy girls and
eight girls with idiopathic scoliosis took part.
A Kistler force platform was
used with a frequency of 100 Hz for recording data.
The center of pressure was
recorded in different positions out of brace for scoliosis and healthy subjects.
Test conditions were single limb and double limb stance, with eyes open and
closed, and foam and rigid surfaces. RESULTS: The data reflected a weak balance
of idiopathic scoliosis subjects compared to healthy subjects. After 1 and 4
months of wearing the brace, center of pressure and center of gravity sway
increased in the majority of the tests, although there were no significant
differences in any of the test conditions (p > 0.05). While the center of
pressure sway in medio-lateral direction decreased after 4 months of wearing a
brace, in other variables center of pressure and center of gravity sway
increased. CONCLUSION: Idiopathic scoliosis patients have weak balance in
comparison to healthy subjects. In addition, following a period of 4 months of
wearing a brace, balance parameters in the scoliosis subjects did not improve.
The results show that we need more follow-up of orthoses wearing in idiopathic
scoliosis subjects and suggest more studies at least 1-year follow-up to identify
the efficiency of brace wear on balance. CLINICAL RELEVANCE: Scoliosis can alter
postural stability and balance performance during quiet standing. Spinal
deformity can alter a subject's ability to compensate for postural changes and
cause gait deviations. This study investigated balance differences between the
healthy and idiopathic scoliosis patients and the results of thoraco lumbo sacral
orthosis brace wear. It might provide some new insight into the conservative
treatment of idiopathic scoliosis patients for clinicians and researchers.
