| Summary: | Background: Anterior cruciate ligament reconstruction (ACLR) causes a reduction in the
balance of the lower extremities. Static and dynamic balance were evaluated separately to
confirm the decrease in balance in patients underwent ACLR. The commonly used methods
include the Biodex Balance System (BBS) for static balance and the Y balance test (YBT) for
dynamic balance. No study has evaluated whether the static and dynamic balance of the involved
side recovers as much as the uninvolved side one year after ACLR.
Objects: The purpose of this study was to investigate the recovery of static and dynamic balance
between the involved and the uninvolved sides.
Methods: The BBS (overall, anteroposterior index, and mediolateral index) and YBT (anterior,
posterolateral, and posteromedial) of 58 patients underwent ACLR were measured one year
postoperation. Both sides of the BBS and the YBT were compared using the paired t-test.
Results: All the index of the BBS showed no difference between the involved and the uninvolved
sides, while all the scores of the YBT showed a significant difference in both sides. The
YBT anterior result was 54.64 ± 5.62 cm in the involved side and 56.90 ± 5.41 cm in the uninvolved
side (p = 0.001). The YBT posterolateral results were 90.12 ± 10.51 cm and 92.34 ±
9.85 cm (p = 0.013). The YBT posteromedial results were 93.72 ± 8.84 cm and 96.14 ± 9.37
cm (p = 0.002).
Conclusion: A year after ACLR, the static balance showed no difference, while the dynamic
balance showed a significant difference in the involved and the uninvolved sides. The static
balance of the involved side recovered as much as the uninvolved side, but the dynamic balance
did not. Therefore, dynamic balance training should be considered in the rehabilitation
program for patients underwent ACLR. |
