“…Other studies have reported that a larger trunk lateral tilt toward the stance leg increases the peak knee abduction moment during side-step cutting (Dempsey, Lloyd, Elliott, Steele, Munro, & Russo, 2007;Jamison, Pan, & Chaudhari, 2012). In addition, the increase in intended trunk lateral tilt or rotation during landing increased the knee abduction and internal rotation angles and moments (Critchley et al, 2020;Hinshaw, Davis, Layer, Wilson, Zhu, & Dai, 2019;Saito, Okada, Sasaki, & Wakasa, 2020). However, the effects of the landing instruction to decrease trunk lateral motion on knee kinematics were unclear.…”

“…The three important muscles investigated in the current research were RF, ST, and GM, which originate from the pelvis and are involved in the occurrence of knee injuries [17,18,28,34]. According to our ndings, only the GM muscle activity was signi cantly different between the subjects with and without lumbopelvic control regarding the ability to stand on one leg.…”

“…In particular, the combination of knee valgus and lateral trunk exion on the frontal plane is highly sensitive in the identi cation of women at risk of ACL injuries [27]. In this regard, individuals with lateral trunk exion have increased knee valgus, and lateral exion of the trunk could cause the ground reaction force to pass through the lateral compartment of the knee and increase the abduction torque exerted on it [28]. Similarly, poor neuromuscular control of the trunk can be associated with knee injuries in women [13].…”

Background: Lumbopelvic control has recently been associated with function, kinesiology, and limb loading. However, poor lumbopelvic control has not been studied as a risk factor for lower limb injury in sports with frequent jump landings. The present study aimed to investigate the effects of lumbopelvic control on landing mechanics and lower limb muscle activity in professional athletes with frequent landing.Methods: This study was conducted on 34 professional female athletes aged 18.29±3.29 years with the mean height and weight of 173.5±7.23 centimeters and 66.79±13.37 kilograms, respectively. The lumbopelvic control of the subjects was evaluated using the knee lift abdominal test, bent knee fall-out, active straight leg raising, and PRONE test by the pressure biofeedback unit. Based on the test results, the participants were equally divided into two groups of with and without lumbopelvic control (n=17). Landing mechanics were evaluated by an expert blinded to the procedures using the landing error scoring system (LESS) and two-dimensional video analysis. In addition, electrical muscle activity in single-legged standing skills was assessed via surface electromyography.Results: The results of independent samples t-test indicated significant differences between the groups with and without lumbopelvic control in terms of the LESS test scores (P=0.0001), lateral trunk flexion (P=0.0001), knee valgus (P=0.0001), knee flexion (P=0.001), trunk flexion (P=0.01), and gluteus medius muscle activity (P=0.03). However, no significant differences were observed in the activity of the rectus femoris and semitendinosus muscles, and ankle dorsiflexion (P>0.05).Conclusions: Poor lumbopelvic control affects the kinematics and electrical activity of the lower limb muscles and may be a risk factor for lower limb injuries, especially knee injury.

“…It was hypothesized that female subjects would show larger knee abduction angle and moment compared to male subjects during landing with lateral trunk obliquity. This was motivated by the fact that larger knee abduction angle and moment increased by the lateral trunk obliquity was a proposed female speci c ACL injury mechanism [13,17,25]. However, we failed to nd gender-based differences in knee kinetic or kinematics.…”

Background: Lateral trunk obliquity during landing is one of the characteristics of anterior cruciate ligament (ACL) injuries in female athletes. Knee biomechanics during landing with lateral trunk obliquity may be different between female and male subjects. The purpose of the present study was to compare kinetics and kinematics in female subjects during landing with lateral trunk obliquity with those in male subjects.Methods: Fifteen female (age 22.0 ± 1.6 years) and 15 male subjects (age 21.7 ± 1.1 years) participated in this study. The subjects performed a single-leg landing from a 30-cm-high box. Subjects were instructed to keep inclining their trunk to landing leg side at 15° from vertical line. Kinetics and kinematics of their hip and knee joints were analyzed using a three-dimensional motion analysis system with a force plate and compared between female and male subjects.Results: There were no significant differences in the angle of the laterally inclined trunk at initial contact (IC) and at the time of peak vertical ground reaction force (VGRF) (P = 0.341, 0.363). The peak VGRF was smaller in female subjects than male subjects (P = 0.047). Hip adduction moment at the time of peak VGRF was significantly larger in female subjects than male subjects (P = 0.042). Hip external rotation of female subjects at IC was significantly larger than that of male subjects (P = 0.012). There were no differences in knee moments or kinematics between female and male subjects.Conclusions: The findings of the present study indicated that female athletes are considered to avoid excessive knee abduction moment during landing with lateral trunk obliquity by kinematic and kinetic changes in their hip joint. Therefore, sports-medicine specialists should take more notice of kinematics and kinetic behaviors around hip joint in order to prevent noncontact ACL injuries for female athletes.
