Landing Error Scoring System Scores Differ During Various Types Of Jump-Landing Tasks

Context: Large-scale inexpensive pre-participation examination screening tools need to be developed to evaluate individuals at risk for lower extremity injury (e.g., anterior cruciate ligament [ACL]). One tool, the Landing Error Scoring System (LESS) has shown promise in assessing clinical biomechanical jump-landing motion patterns in an inexpensive manner. However, the effectiveness of the LESS to assess various types of jump-landing tasks has yet to be reported. Objectives: To determine the effects of a box-drop (BD) jump-landing task versus a running stop-jump (SJ) task with or without the presence of an overhead object.
