Abstract
Unilateral Discogenic Sciatica is defined as low back pain radiating to
one lower limb, and it may be combined with one or more positive neurological signs.
This pain may cause loss of function, reduce quality of life and working capability.
Objective: This study was conducted to determine the relationship between postural
control and risk of falling in patients with unilateral discogenic sciatica. Subjects and
Methods: Sixty subjects participated in the study (30 patients with unilateral
discogenic sciatica and 30 matched healthy controls). All participants undergone
balance assessment using PROKIN system to evaluate static and dynamic balance.
The risk of falling was assessed using Berg Balance Scale (BBS). Results: There was
a significant increase in all static balance variables (sway range forward backward and
mediolateral, velocity of body sway forward backward and mediolateral, total sway
area and total sway perimeter) and a significant decrease in dynamic balance variable
(limit of stability LOS) of the study group compared with the control group (P <0.05).
There was a significant positive correlation between BBS score and dynamic balance
(LOS) in patients with unilateral discogenic sciatica (P= 0.001), whereas, the
correlation between BBS score and static balance was non-significant. Conclusion:
Unilateral sciatica affects both static and dynamic balance and increases the risk of
falling in patients with unilateral discogenic sciatica.
