Performance measures such as strength, jump height/length, and change of direction (CoD) time during anterior cruciate ligament (ACL) rehabilitation have been used to determine readiness return play identify those who may be at risk rerupture. However, athletes reach these criteria despite ongoing biomechanical deficits when performing tests. Combining return-to-play with an assessment movement through 3-dimensional (3D) biomechanics in male field sports factors for ACL rerupture has not...
Background: Athletes are twice as likely to rupture the anterior cruciate ligament (ACL) on their healthy contralateral knee than reconstructed graft after ACL reconstruction (ACLR). Although physical testing is commonly used ACLR assess injury risk operated knee, strength, jump, and change-of-direction performance biomechanical measures have not been examined in those who go experience a injury, identify factors that may be associated with risk. Purpose: To prospectively examine differences...
Introduction Previous studies examining jump tasks after anterior cruciate ligament reconstruction ( ACLR ) have focused on performance measures without joint kinematic and kinetic variables. The aim of this study was to identify differences in biomechanical between limbs across tests 9 months surgery. Methods Four (double‐leg drop DLDJ ), single‐leg SLDJ hop for distance SLHD hurdle HH )) were carried out 156 male subjects a 3D motion capture laboratory Statistical parametric mapping used...
The aim of this study was to establish alterations in vertical and lower-limb joint stiffness following anterior cruciate ligament reconstruction (ACLR). 127 male patients 8-10 months post-ACLR 45 non-injured controls performed unilateral bilateral drop jumps, cutting, while ground reaction forces (GRFs) 3D kinematics were recorded. Stiffness changes GRF lower ACLR during jumps compared controls. also displayed knee the (d=-0.91, p < 0.001 d = 0.53, 0.001, respectively) cutting (d=-0.85,...
Abstract After anterior cruciate ligament reconstruction (ACLR), there is a higher re‐injury rate to the contralateral limb in athletes who undergo surgery using bone‐patellar‐tendon‐bone (BPTB) autograft than semitendinosus and gracilis hamstring tendon (HT) autograft. This may be influenced by differing lower‐limb loading asymmetries present when of each graft type return play (RTP). The aim this study was compare bilateral countermovement jump (CMJ) phase‐specific impulse between with...
To characterize chest compression (CC) pause duration during the last 5 minutes of pediatric cardiopulmonary resuscitation (CPR) prior to extracorporeal-CPR (E-CPR) cannulation and association with survival outcomes.Cohort study from a quality collaborative including E-CPR cardiac arrest events ≥ 10 min CPR data. We characterized CC interruptions defibrillator-electrode recorded (prior cannulation) assessed between longest outcomes using multivariable logistic regression.Of 49 events, median...
Deficits in knee strength after anterior cruciate ligament reconstruction (ACLR) surgery are common. the single-leg drop jump (SLDJ), a test of plyometric ability, also found.To examine relationship between isokinetic strength, SLDJ performance, and self-reported function 9 months ACLR.Cross-sectional study; Level evidence, 3.Knee peak torque, height, contact time, reactive index (RSI), as well International Knee Documentation Committee (IKDC) scores were assessed 116 male, field-sport...
After anterior cruciate ligament reconstruction (ACLR), there are differences in the neuromuscular deficits observed patients with bone‐patellar tendon‐bone (BPTB) and hamstring tendon (HT) autografts. The knee extensor flexor strength commonly reported, but analyses have largely focused on peak torque metrics despite requirement to generate through range when returning sport. aim of this study was investigate angle‐specific asymmetry between BPTB HT around time return play after ACLR. A...
The aim of this study was threefold (1) to assess the reliability three upper-extremity performance tests: a countermovement push up, press jump and drop box land, performed on set dual-force plates (2) examine whether there an association between isokinetic dynamometry tests in non-injured cohort collision/contact athletes (3) establish normal descriptive profile vertical ground reaction forces from tests, contact/collision athletes. split into two sub-sections; inter-day (n = 21)...
Later-stage rehabilitation following anterior cruciate ligament (ACL) reconstruction (ACLR) provides a valuable opportunity to target performance deficits before return sport. This study aimed to: (1) evaluate bilateral counter-movement jump (CMJ) phase-specific impulse and isokinetic strength inter-limb asymmetry progression from 6 9 months post-ACLR; (2) examine the extent which individual changes in could explain asymmetry. Male athletes (n = 44) with hamstring tendon or bone-patellar...
Despite decades of evidence revealing a multitude ways in which animals are adapted to minimize the energy cost locomotion, little is known about how expenditure shapes adaptive gait over complex terrain. Here, we show that principle optimality human locomotion can be generalized task-level locomotor behaviours requiring advance decision-making and anticipatory control. Participants completed forced-choice task them choose between discrete multi-step obstacle negotiation strategies cross...
This paper presents an analysis of the low-level features and key spatial points used by humans during locomotion over diverse types terrain. Although, a number methods for creating saliency maps task-dependent approaches have been proposed to estimate areas image that attract human attention, none these can straightforwardly be applied sequences captured locomotion, which contain dynamic content derived from moving viewpoint. We novel learning-based method visual priority map informed eye...
There are currently a multitude of tests used to assess readiness return sport (RTS) following anterior cruciate ligament reconstruction (ACLR). The aim this study was establish the extent which movement strategies transfer between three common assessment tasks help improve design athlete testing batteries ACLR. A cohort 127 male patients 8-10 months post-ACLR and 45 non-injured controls took part in study. Three were completed (unilateral bilateral drop jump, 90° pre-planned cut), while...
Nine months after anterior cruciate ligament (ACL) reconstruction, athletes who undergo surgery using a bone-patellar-tendon-bone (BPTB) autograft demonstrate higher loading asymmetries during vertical jumping than those with hamstring tendon (HT) autograft. These may transfer into sporting movements greater ACL injury risk. The aim of this study was to compare between-limb in knee mechanics and task performance an unplanned 90° change-of-direction (CoD) male field sport reconstructed BPTB...
Cutting maneuvers can be executed at a range of angles and speeds, these whole-body task descriptors are closely associated with lower-limb mechanical loading. Asymmetries in angle speed when changing direction off the operated nonoperated limbs after anterior cruciate ligament reconstruction may therefore influence interpretation interlimb differences joint-level biomechanical parameters. The authors hypothesized that athletes would reduce center-of-mass heading deflection body rotation...
Athletic groin pain (AGP) is a chronic, painful condition which prevalent in players of field sports that require rapid changes direction. Following successful rehabilitation, systematic have been observed the kinetics and kinematics pre‐planned change direction maneuvers, providing insight into potential foci for rehabilitation monitoring assessment interventions. However, changing often reactive rather than pre‐planned, it not known whether such post‐rehabilitation are seen maneuvers. We...
The primary aim was to identify and quantify differences in interlimb asymmetry magnitudes across a battery of upper extremity strength performance tests at 4 6 months after glenohumeral joint stabilization surgery shoulder contact collision athletes compared with an un-injured group. A secondary investigate if identified changed from surgery. third explore associations within the different variables.Fifty-six male sport who had undergone unilateral were tested An control group ( n = 39 for...
