Resumo do estudo

Thirty athletes following anterior cruciate ligament (ACL) reconstruction were randomized to receive whole-body vibration (WBV) combined with routine exercise therapy or routine exercise therapy alone. The primary outcomes of interest were Stability Index (SI) and Time to Stabilization (TTS) during a jump-landing task. Secondary outcomes included Y-Balance Test (YBT) performance and Limb Symmetry Index (LSI) derived from the 6-meter timed hop test (6MTH). Outcomes were assessed before and after 12 treatment sessions over 4 weeks. Overall, the results of the study revealed that the addition of WBV significantly improved TTS in the anteroposterior and resultant directions, while both groups demonstrated similar improvements in balance and functional performance outcomes. These findings suggest WBV may provide selective benefits for dynamic postural stability during sport-specific tasks after ACL reconstruction.
