“…Therefore, data of each subject were compared with the belonging expert based on height, and analyses were performed on the deviation waveforms. Finally, besides the upcoming number of studies using SPM mapping in biomechanics ( 62 ), this study used nonlinear registration to perform multivariate analysis of both amplitude and timing effects. This is important because amplitude and timing are generally associated with different biomechanical constructs and typical SPM results (of linearly registered data) can be ambiguous in terms of amplitude vs. timing effects.…”

Nijmeijer, EM, Kempe, M, Elferink-Gemser, MT, and Benjaminse A. Observe, practice and improve? Enhancing sidestep cutting (SSC) execution in talented female soccer players: A four-week intervention program with video instruction. J Strength Cond Res XX(X): 000–000, 2024—Implicit learning has the potential to improve movement execution and reduce injury risk. Previous research showed beneficial effects of short-term interventions with implicit learning in male athletes. However, research on long-term interventions in female athletes is lacking. The aim of this study was to examine the effects of a 4-week intervention with video instruction on movement execution of SSC, a task that is highly related with anterior cruciate ligament (ACL) injury risk, in female athletes. Twenty talented adolescent female soccer players were part of the control (CTRL, n = 10) or video instruction (VIDEO, n = 10) group. All subjects practiced 4 weeks and received general task instructions. In addition, the VIDEO group received expert video instruction during practice. Lower extremity kinematics and kinetics and vertical ground reaction force of SSC were examined during baseline, immediate post, and 1-week retention tests. After nonlinear registration, differences between each subject and the expert she had seen were determined. These differences were analyzed with SPM1D 2-way ANOVA. No interaction effects between time and group were found (p > 0.05). Main effects of time were found in the frontal plane. In particular, smaller deviations of subjects compared with the seen expert of the knee adduction (p = 0.005, 97.9–100% stance phase [SP]) and hip abduction (p = 0.005, 11.5–13.8% SP) and adduction (p < 0.001, 33.4–87.7% SP) moments were found in immediate post compared with baseline. These frontal plane short-term improvements, replicating earlier findings in both sexes, may lower ACL injury risk. The large observed interindividual differences over time may have concealed the long-term effects of video instruction at the group level.

Introduction: Anterior Cruciate Ligament Reconstruction (ACLR) is crucial for knee stability in ACL-injured individuals and for resuming pre-injury physical activities. Despite advancements, achieving symmetrical movement patterns during rehabilitation, particularly in stair negotiation, poses challenges. This study examines lower limb kinematics during stair negotiation at various rehabilitation stages post-ACLR, employing inertial measurement units (IMUs) and Statistical Parametric Mapping (SPM) for in-depth analysis outside the laboratory. Methods: This cohort study longitudinally assessed stair ambulation kinematics in patients aged 18-40, three (n=26) and five months (n=18) post-ACLR, using IMUs to track sagittal plane movement during stair ascent and descent. The participants ambulated on a flight of 20 stairs outside the laboratory. Results: At three months post-ACLR, the injured knee was less flexed compared to the contralateral knee during stair ascent (mean difference = -11.3, CI [-14.4, -8.1], p<.001) and descent (mean difference = -6.3, CI [-10.2, -2.4], p=.002). SPM analysis identified clusters where the injured knee showed decreased flexion at 0-35% and 87-99% of the stair ascent cycle (p<.005). By five months, flexion differences during ascent improved (mean difference = -4.7, CI [-8.1, -1.4], p=.008), but significant asymmetry persisted, with decreased flexion at 10-32% of the cycle during ascent and 20-29% during descent (p<.017). Improvements between three and five months were observed in knee flexion during ascent (mean increase = 6.1, p<.001) and descent (mean increase = 9.3, p=.004). Ankle and hip joint movements also exhibited persistent asymmetries, with minimal improvements over time. Conclusions: Persistent lower limb kinematic asymmetries remain five months post-ACLR during stair ascent and descent.

Background: The understanding of noncontact anterior cruciate ligament (ACL) injury causation in soccer has improved over the past decades. Bidimensional video analyses have significantly augmented our awareness, representing to date the only practical method to describe injury biomechanics. However, the extent of the problem continues to raise serious concerns. Purpose: To advance our understanding of the causal pathways leading to ACL injury with a large-scale reconstruction of 3-dimensional (3D) whole-body joint kinematics of injuries that occurred to male elite soccer players, as well as to compare the joint angle time course among situational patterns. Study Design: Descriptive laboratory study. Methods: A total of 33 consecutive noncontact and indirect contact ACL injuries that occurred in 6 national and 2 international professional leagues (seasons 2020-2021 to 2022-2023 until December 2022) were analyzed: (1) multiview noncoaxial television images were inspected; (2) multiple camera views were taken from 400 ms before the initial ground contact to 200 ms after the injury frame; (3) a size-matched pitch was modeled and used to calibrate cameras; (4) a 3D skeletal model was adjusted to fit the player's pose in each frame/view; and (5) poses were interpolated, and Euler joint angles were extracted. Results: The authors reconstructed the 3D lower limb joint kinematic curves preceding and during ACL injuries in 33 cases; notably, a sudden external (up to 5°) and then internal knee rotation was observed after the initial contact and before the injury frame. The overall kinematics at injury were knee moderately flexed (45.9°± 21.7°), abducted (4.3°± 5.1°), and externally rotated (3.0°± 6.4°); trunk shallowly flexed (17.4°± 12.5°) and rotated and tilted toward the injured side; and hip flexed (32.0°± 18.7°), abducted (31.1°± 12.0°), and slightly internally rotated (6.6°± 12.2°). Variable behaviors were observed at the ankle level. Conclusion: Via reconstruction of the sequence of whole-body joint motion leading to injury, we confirmed the accepted gross biomechanics (dynamic valgus trend). This study significantly enriches the current knowledge on multiplanar kinematic features (transverse and coronal plane rotations). Furthermore, it was shown that ACL injuries in male professional soccer players manifest through distinct biomechanical footprints related to the concurrent game situation. Clinical Relevance: Interventions aimed at reducing ACL injuries in soccer should consider that environmental features (ie, situational patterns) affect injury mechanics.
