OBJECTIVE: To investigate the effect on balance control of postural changes
related to ankylosing spondylitis. DESIGN: Thirty-four subjects with ankylosing
spondylitis and 34 healthy individuals were enrolled. Examination of postural
alignment was conducted using lumbar Schober, hand to ground distance, tragus to
wall distance and occiput to wall distance measurements, and Bath Ankylosing
Spondylitis Metrology Index. Balance was evaluated by Berg Balance Scale,
Functional Reach Test, Lateral Reach Test, and Static Balance Index. Postural
sway during quiet standing was assessed by centre of pressure displacement in 2
conditions: eyes open and eyes closed. RESULTS:
Functional reach test and
right-side lateral reach tests were significantly lower in subjects with
ankylosing spondylitis. Eyes closed anteroposterior centre of pressure sway was
significantly higher in the subject group. CONCLUSION: Ankylosing spondylitis can
lead to balance deterioration due to postural changes.
