Cutting ability is an important aspect of many team sports, however, the biomechanical determinants cutting performance are not well understood. This study aimed to address this issue by identifying kinetic and kinematic factors correlated with time complete a maneuver. In addition, analysis test-retest reliability all measures was performed. Fifteen (n = 15) elite multidirectional sports players (Gaelic hurling) were recruited, 3-dimensional motion capture 75° cut undertaken. The associated...
Context: Despite an increase in the literature, few definitive guidelines are available to determine when athlete has been fully rehabilitated after anterior cruciate ligament reconstruction (ACLR). Objective: To examine countermovement jump and isokinetic dynamometry measures (1) identify which can best distinguish between ACLR control participants (2) provide normative values for identified young adult male multidirectional field-sport athletes. Design: Cross-sectional study. Setting:...
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...
Vertical jump tests are more sensitive in revealing asymmetries performance metrics at the time of return to sport after anterior cruciate ligament (ACL) reconstruction (ACLR) than horizontal hop tests. However, it remains unclear which vertical (bilateral or unilateral) and (kinetics performance) most effective informing rehabilitation status readiness for sport. We aimed investigate athletes during testing ACLR.A dual force platform system was used evaluate jumping 126 recreational...
Background: Favorable outcomes after anterior cruciate ligament (ACL) reconstruction (ACLR) are often gauged by successful return to play (RTP), a low incidence of subsequent ACL injury, and positive patient-reported outcomes. Level 1 sports place the highest demands on knee requiring frequent pivoting, changes in direction, jumping. Purpose: To analyze primary ACLR level athletes identify pre- intraoperative factors associated with RTP, ipsilateral reinjury, contralateral International Knee...
Objective Most studies examining the time to return sport (RTS) after anterior cruciate ligament reconstruction (ACLR) do not account for athlete’s physical readiness. This study aimed investigate status of male athletes at 2 years ACLR, factors affecting a pivoting sports, and association between RTS subsequent knee injury risk those who met discharge criteria. Methods We prospectively followed 530 (mean age 26.7±7.7 years) participating in sports throughout rehabilitation ACLR. Pair-wise...
Clinical assessments and rehabilitation in athletic groin pain (AGP) have focused on specific anatomical structures uniplanar impairments rather than whole body movement.To examine the effectiveness of that targeted intersegmental control patients with AGP to investigate post changes cutting biomechanics.Two hundred five were rehabilitated focusing clinical assessment control, linear running change direction mechanics this prospective case series. Hip Groin Outcome Score (HAGOS) was primary...
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...
After anterior cruciate ligament reconstruction (ACLR), athletes have demonstrated performance asymmetries as compared with healthy cohorts, but little research has investigated if biomechanical are also different during jump and change-of-direction (CoD) tasks between groups.To identify differences in magnitude of asymmetry variables exist these groups.Controlled laboratory study.Analysis was conducted 156 male patients 9 months after surgery 62 participants. Three-dimensional motion...
Background: Despite the importance of return-to-play (RTP) rates, second anterior cruciate ligament (ACL) injury and patient-reported outcomes athletes returning to sports after ACL reconstruction (ACLR), these have not been evaluated together across a single cohort nor pre- intraoperative factors influencing explored. Purpose: To prospectively report ACLR relating RTP, injury, International Knee Document Committee (IKDC) scores in large at center examine influence variables on outcomes....
Background: Psychological factors including self-reported readiness to return sport (RTS) after anterior cruciate ligament reconstruction (ACLR) measured with the Anterior Cruciate Ligament Return Sport After Injury (ACL-RSI) scale have been shown correlate RTS. Physical deficits exist in later stages ACLR rehabilitation. No previous studies investigated relationship between RTS and objective physical measures of power strength. Purpose: To investigate ACL-RSI scores strength ACLR. Study...
Background Athletic groin pain remains a common field-based team sports time-loss injury. There are few reports of non-surgically managed cohorts with athletic pain. Aim To describe clinical presentation/examination, MRI findings and patient-reported outcome (PRO) scores for an cohort. Methods All patients had history including demographics, injury duration, sport played standardised examination. underwent PRO score to assess recovery. A diagnosis the injured anatomical structure was made...
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...
After anterior cruciate ligament reconstruction (ACLR), return to sprint is poorly documented in the literature. In soccer, an essential component of play and performance after ACLR. The characteristics running soccer are specific (velocity differences, nonlinear, intensity). It important address these particularities, such as curvilinear running, acceleration, deceleration, changes direction, variations velocity, patient's rehabilitation program. Force, acceleration capacities key elements...
BACKGROUND: The anterior cruciate ligament (ACL) plays an important sensory role within the sensorimotor system. Following ACL injury, dysfunction can have implications for rehabilitation and risk of reinjury. CLINICAL QUESTION: What occurs system following how clinicians assess it? KEY RESULTS: across system: afferent pathways, efferent pathways central processing. exhibit somatosensory ([1] increased pain swelling, [2] cortical processing [3] reduced proprioception). There is also in...
While measures of asymmetry may provide a means identifying individuals predisposed to injury, normative values for challenging sport specific movements in elite athletes are currently lacking the literature. In addition, previous studies have typically investigated symmetry using discrete point analyses alone. This study examined biomechanical rugby union players both and continuous data analysis techniques.Twenty injury free international (mean ± SD: age 20.4 1.0 years; height 1.86 0.08 m;...
