descending stairs, 12 , 13 single-leg squatting, 14 , 15 single-leg drop landings, 5 and single-leg vertical jumps 2 compared with those without PFP. Treatment for PFP commonly involves interventions to alter lower-extremity biomechanics either proximal or distal to the patellofemoral joint (PFJ) itself

alterations to balance. 2 – 11 The improper movement pattern associated with DKV is further emphasized during dynamic movements, especially in single-leg tasks when balance is incorporated into the movement, such as in single-leg landing and single-leg jumping maneuvers. 2 The most recent literature on
Single-Leg Hop Stabilization Throughout Concussion Recovery: A Preliminary Biomechanical Assessment
Landon B. Lempke, Matthew C. Hoch, Jarrod A. Call, Julianne D. Schmidt, and Robert C. Lynall
neuromuscular demands during sport activities likely exceed those required to complete the current multidimensional concussion assessment battery. 3 , 4 For example, previous work has identified that reaction time from jumping, cutting, and single-leg hop tasks do not correlate with reaction time from clinical
Thirty-Second Single-Leg Stance Identifies Impaired Postural Control in Children After Concussion: A Preliminary Report

, particularly tandem gait, have been shown to be superior to static tasks in detecting both acute and persistent postconcussive postural deficits. 3 , 9 , 10 However, some static tasks such as single-leg stance of longer duration have identified residual impairments after concussion. 3 , 11 Therefore

decrease in accuracy of knee joint replications, 10 – 12 but others did not. 13 , 14 Since these results were based on examinations using seated open-kinetic chain knee joint replication tests, linking previous results to risk of injury is difficult. According to studies of single-leg landings after knee
Single-Leg Jump Performance Before and After Exercise in Healthy and Anterior Cruciate Ligament Reconstructed Individuals

shift toward a more symmetrical system may be an indication that a patient with ACLR may not be ready to return to high-level exercise, despite appropriate performance during rested symmetry testing. Therefore, the purpose of our study was to compare changes in performance in single-leg hop and 4-jump

Gaze Accuracy Differences During Single-Leg Balance Following Anterior Cruciate Ligament Reconstruction

. Individuals following ACLR were hypothesized to demonstrate lower visual accuracy during a single-leg balance task compared with healthy individuals. These impairments in visual accuracy were hypothesized to have a relationship with decreased postural control. Methods This was a case-control study performed

. Moreover, the single leg bridge test (SLBT), which measures hamstring function, has been used to predict the risk of HSI. 12 In terms of SLBT scores, the number of trials is rated as poor if it is <20, average if it is 25 or more, and good if it is 30 or more. 12 According to a previous study on amateur
