Comparison of Dynamic Balance and Unilateral Hop Performance Between Women and Men Handball Players After Anterior Cruciate Ligament Reconstruction: A Pilot Study.

Abstract

After anterior cruciate ligament reconstruction (ACLR), long-term functional deficiencies can occur, with controversial results reported when comparing women and men. Dynamic balance and unilateral hop test performance are considered important indicators for the risk of reinjury of the lower extremity. Although both sexes seem to have a similar risk to experience a second anterior cruciate ligament injury, sex-specific differences of dynamic balance and unilateral hop performance in handball players following ACLR are unknown. To compare dynamic balance and unilateral hop performance between women and men handball players at least 6months after ACLR. Cross-sectional pilot study. Ten women (27.6 [4.5]y) and 10 men (26.5 [3.1]y) handball players 6 to 16months after ACLR. Dynamic balance and unilateral hop performance were assessed using the Y-Balance Test and the Single-Leg Hop for Distance Test. Women players demonstrated significantly better results in the anterior direction of the Y-Balance Test for both legs compared with men players. Hop performance was not significantly different between sexes. Dynamic balance and single-leg hop performance seem not to differ between women and men handball players 6 to 16months after ACLR. The difference between sexes in the anterior reach direction of the Y-Balance Test should be considered small, rather than representing a true difference.
