Leg length discrepancy (LLD) is a significant factor influencing several pathological conditions. Gait analysis is based on biomechanical gait models calculating joint kinematics; however, no previous study has validated its ability to detect anatomical LLD. The aim of the present study was to compare the validity of the Vicon ® Plug-in-Gait-model (PGM) in measuring femur and tibia segmental length discrepancy with measurements attained by X-ray. Fifteen participants with suspected leg length discrepancies underwent a lower limb X-ray and a standing calibration trial using a motion analysis system (Vicon ® , Oxford Metrics, UK). Femur and tibia segment lengths were deducted from both measurements. No differences were found when measuring the discrepancies between sides for the femur (p = 0.3) and tibia (p = 0.45) segmental length. A high correlation was found between methods (r = 0.808-0.962, p < 0.001), however, a significant difference was observed when measuring the femur and tibia length (p < 0.0001). PGM was found to be a valid model in detecting segmental length discrepancy when based on the location of the joint centers compared to X-ray. A variance was noted in the femur and tibial segmental length. The impact of this inconsistency in segmental length on kinematics and kinetics should be further evaluated.

“…The hip joint center was defined via a least-squares method. 27 Ground reaction forces were sampled via a nonconductive force plate (model 4060-NC; Bertec Corp, Columbus, OH). We placed preamplified surface EMG electrodes (Bagnoli 8 Desktop EMG System; DelSys Inc, Boston, MA) over the vastus lateralis muscle parallel to the direction of action potential propagation to monitor quadriceps activity.…”

Context: Researchers have suggested that large landing forces, excessive quadriceps activity, and an erect posture during landing are risk factors for anterior cruciate ligament (ACL) injury. The influence of knee kinematics on these risk factors has been investigated extensively, but trunk positioning has received little attention.Objective: To determine the effect of trunk flexion on landing forces and quadriceps activation during landing.Design: Two (sex) 3 2 (task) repeated-measures design. Intervention(s): Participants performed 2 drop-landing tasks. The first task represented the natural, or preferred, landing strategy. The second task was identical to the first except that participants flexed the trunk during landing.Main Outcome Measure(s): We measured peak vertical and posterior ground reaction forces and mean quadriceps electromyographic amplitude during the loading phase of landing (ie, the interval from initial ground contact to peak knee flexion).Results: Trunk flexion decreased the vertical ground reaction force (P , .001) and quadriceps electromyographic amplitude (P , .001). The effect of trunk flexion did not differ across sex for landing forces or quadriceps electromyographic activity.Conclusions: We found that trunk flexion during landing reduced landing forces and quadriceps activity, thus potentially reducing the force imparted to the ACL. Research has indicated that trunk flexion during landing also increases knee and hip flexion, resulting in a less erect landing posture. In combination, these findings support emphasis on trunk flexion during landing as part of ACL injury-prevention programs.Key Words: anterior cruciate ligament, ground reaction forces, injury prevention, risk factors Key Points N Trunk flexion during landing reduced landing forces and quadriceps activity. N The influence of trunk flexion on landing forces and quadriceps activity did not differ across sex. N Trunk flexion potentially reduces the quadriceps force requirement and subsequent load placed on the anterior cruciate ligament immediately after ground contact during landing.N Because of its influences on kinetic, kinematic, and neuromuscular risk factors for anterior cruciate ligament injury, active trunk flexion during landing might be an important component of injury-prevention programs.

“…The hip joint centre is an important identifying landmark in human movement analysis as it allows for the determination of the anatomical reference frame of the femur [1]. A number of techniques currently exist that include anatomical [6], functional [7,8] and projection [9] methods, all of which may influence the resultant hip and knee joint profiles [5]. Although the validity of each method has been reported to justify their utilization, there is currently a lack of information regarding the influence of the three available hip joint centre location techniques on 3-D kinematic parameters during fencing movements and the interchangeable use of each technique [10].…”

Purpose. The lunge is a fundamental offensive fencing technique, common to all contemporary fencing styles. Therefore, when using 3-D kinematic analysis to quantify lower extremity rotations during the fencing lunge, it is important for researchers to correctly interpret this movement. Locating the centre of the hip is required to accurately quantify hip and knee joint rotations, with three non-invasive techniques using anatomical, functional and projection methods currently available for the estimation of hip joint centre. This study investigated the influence of these three techniques on hip and knee joint kinematics during the fencing lunge. Methods. Three-dimensional kinematics of the lunge were collected from 13 experienced epee fencers using an eight-camera motion capture system. The 3-D kinematics of the lunge were quantified using the three hip joint centre estimation techniques. repeated measures ANOVAs were used to compare the discrete 3-D kinematic parameters, and intra-class correlations were employed to identify similarity across the 3-D kinematic waveforms from the three techniques. Results. The results indicate that whilst the kinematic waveforms were similar (R 2 0.96); significant differences in discrete parameters were also evident at both the hip and knee joint in the coronal and transverse planes. Conclusions. It appears based on these observations that different hip joint centre locations can significantly influence the resultant kinematic parameters and cannot be used interchangeably.
