Correlation of Y Balance with Clinical Scores and Functional Tests after Anterior Cruciate Ligament Reconstruction in Young and Middle-Aged Patients

Abstract

Background Criteria for return to sports (RTS) following anterior cruciate ligament (ACL) reconstruction have been extensively studied. But there is no consensus among investigators regarding which factors are most important in determining a safe RTS. Methods Sixty-one patients who underwent ACL reconstruction were included. Subjective knee scoring systems (International Knee Documentation Committee [IKDC] score and Lysholm score), functional performance tests (carioca test and single-leg hop for distance [SLHD] test), and isokinetic knee strength test were used for assessment and analyzed for association with the limb symmetry index (LSI) of the Y-balance test for lower quarter (YBT-LQ). Results The LSI of the YBT-LQ was significantly correlated with Lysholm score, IKDC score, Carioca, LSI for the SLHD, and extensor strength deficit at 6 months after ACL reconstruction. At 12 months, Lysholm score, IKDC score, LSI for the SLHD, and extensor strength deficit were significantly correlated with the LSI of the YBT-LQ. Conclusions The YBT-LQ test could be used conveniently as an additional tool to assess the patient’s functional performance results after ACL reconstruction in outpatient clinics.

Dynamic Single-Leg Balance Tests of Physiotherapy Students: A Comparison of Body-Active Weight Shift Test and Two Sudden Disturbance Tests

“…Functional tests of the active body-weight shift test [2] require strength, mobility, neuromuscular control, stability, range of motion, balance, and proprioception and are related to lower limb strength. When performing the test, subjects must lean forward and backward to maintain balance, and the knee flexors must contract eccentrically to resist trunk movement [27], [50]. Poor results on the forward, backward, and inward reach tests can indicate chronic instability of the ankles [29].…”

Short-term effects of kinesiology taping on static and dynamic balance in healthy subjects

“…The maximum reach distances for three directions during the Y-Balance test were collected using a Laser Distance Meter (RSCLLDM-50H, United Kingdom). The YBTCS was then calculated and collected as the sum of maximum reach distances in three directions divided by 3 times limb length and then multiplied by 100% ( Kim et al, 2022 ).…”

Enhancing Post-Surgical Rehabilitation Outcomes in Patients with Chronic Ankle Instability: Impact of Subtalar Joint Axis Balance Exercises Following Arthroscopic Modified Broström Operation

“…The composite scores were computed by summing the reach distances of the anterior, posteromedial, and posterolateral directions, dividing the total by three times the participant's leg length, and then multiplying by 100 to obtain a percentage. The distance between the anterior superior iliac spine and the most distal region of the medial malleolus was measured [35,36]. The rest period between tests was 20 s, and the total testing duration was 15 min.…”
