Compensatory Movement Strategies during the Rearfoot Elevated Split Squat after ACL Reconstruction

Inter- and intra-limb compensation strategies were observed in the ACL-involved limb during the RFESS. Performing the RFESS with a more upright trunk may exacerbate inter-limb compensation, promoting offloading of the lead limb. Collectively, these findings suggest that without careful monitoring, the RFESS may be ineffective as a knee extensor strengthening exercise during mid-stage ACL rehabilitation.
