“…Kinematic and GRF data were filtered with a fourth-order low-pass Butterworth filter at a cutoff frequency of 12 Hz, which was determined from a residual analysis. 22 The kinematic data were used as inputs to a computed tomography-scan based extended dynamic foot model (https:// simtk.org/projects/kul_footmodel). 1 This model consists of five segments (talus, calcaneus, midfoot, forefoot, and toes), 8 degrees of freedom, 37 ligaments (including ATFL and CFL) in each foot and 152 muscles (including soleus and gastrocnemius) in the whole body.…”

Multi‐segment foot models (MFMs) are becoming a common tool in musculoskeletal research on the ankle‐foot complex. The purpose of this study was to compare ankle joint kinematics as well as ligament and muscle strains that result from MFM with a different number of segments during vertical hopping. Ten participants were recruited and performed double‐limb vertical hops. Marker positions and ground reaction forces were collected. Two‐segment (2MFM), three‐segment (3MFM), and five‐segment MFM (5MFM) were used to calculate ankle kinematics and the strains of the anterior talofibular and calcaneofibular ligaments and of the soleus and gastrocnemius muscles. Ranges of motion and peak strains were analyzed with Kruskal–Wallis and post hoc tests, whereas the time‐series of the ankle kinematics and ligament and muscle strains were analyzed with statistical parametric mapping. There were significant main effects for MFM in the talocrural joint range of motion and peak strains of ligaments and muscles. In addition, there were significant main effects for MFM in time‐series data of the talocrural joint angle as well as for ligament and muscle strains. In all cases, the post hoc analyses showed that the 2MFM consistently overestimated the range of motion and tissue strains compared to the 3MFM and 5MFM, while 3MFM and 5MFM did not differ from each other in the most variables. This study showed that the number of segments in MFM significantly affects the biomechanical estimates of joint kinematics and tissue strains during hopping. Clinical significance: MFM that combine all foot structures beyond the talus into one segment likely overestimate ankle joint biomechanics. © 2019 Orthopaedic Research Society.

“…The lower knee valgus, approximately 5 , in the experimental group might hold clinical relevance because excessive knee valgus has been shown to be an independent risk factor for ACL injury [14]. The verbal instructions used in this study partly aimed to direct the participants' attention toward the adjacent joints because knee valgus has been shown to be affected by displacement of the pelvis [28] and the trunk in the frontal plane [24]. The instructions were also similar to the instructions used in preventive exercises for knee injury [12].…”

“…Based upon the instructions used in a previous knee injury prevention programme [12], these instructions were phrased: "Keep your knee aligned with your foot and maintain a stable trunk by contracting your core muscles". The instructions for contracting the trunk muscles were added because excessive movements of these segments have been shown to effect knee alignment [24]. The control group only received task execution instructions (i.e.…”

“…An eight-camera motion analysis system (Elite 2002, version 2.8.4380; BTS, Milan, Italy) was used to record at 100 Hz the position of six spherical retro-reflective markers located on the greater trochanter, the proximal femur (the midpoint between the spina iliaca anterior superior and the apex patella), the lateral and medial femoral epicondyles, the tibia (the midpoint between the apex patella and the midpoint between the two ankle malleoli), and the lateral malleolus of the dominant leg [24,25]. Simultaneously with the kinematic data collection, ground reaction forces (GRFs) were measured at 100 Hz using two Kistler force plates (0.5 Â 0.5 m) (Kistler Group, Winterthur, Switzerland).…”

Background:Little is known about the effects of verbal instructions on the technique and performance of sports-related tasks. The aim of this study was therefore to investigate the acute effects of knee alignment instructions on knee kinematics and the performance of a single-leg jump in female adolescent soccer players. Methods: Twenty-eight adolescent female soccer players completed three blocks of 15 single-leg jumps. The participants were randomised to an experimental group receiving verbal instructions focussing on proper knee alignment (the avoidance of knee valgus) or to a control group only receiving instructions on task execution. Outcomes were knee kinematics (flexion and valgus angles) and jump performance (number of incorrect trials and contact time).Results: The experimental group demonstrated 36% less knee valgus and 11-13% greater knee flexion compared to the control group. While jump performance remained unchanged in the experimental group over the course of the experiment, the control group demonstrated a 20% decrease in the number of incorrect trials and a 25% reduction in contact time over the course of the experiment. Conclusions: The present results indicate that verbal instructions accentuating proper knee alignment benefit knee kinematics but not jump performance in adolescent female soccer athletes.

Purpose: This study was a cross-sectional study that aimed to compare the total LESS scores of individuals with PFP with healthy controls and assess the association of pain, function, and psychological factors with LESS score. Methods: Twenty-seven male athletes with PFP completed a standardized jump-landing task. They were compared with a matched, healthy group. Also, participants completed four questionnaires involving the visual analog scale (VAS), Anterior knee pain scale (AKPS), fear of motion (TAMPA), beck anxiety and depression inventory scale (BAI, BDI).Results: PFP group had a higher total LESS score than the control group signi cantly. They had errors when landing with lateral trunk exion and less knee exion in the initial contact. Our results showed a signi cantly strong correlation between VAS, AKPS, and TAMPA with a nal score LESS. Also, a low to moderate signi cant correlation obtained between BAI, BDI and nal score LESS.Conclusions: The LESS is a useful clinical test for evaluating landing errors in people with PFP. Greater kinesiophobia, pain, poorer self-reported function and psychological factors was correlated with a total LESS score.
