O 073 - Effect of Trunk Motion Restriction on the Muscle Activities of Shoulder External Rotators during Throwing
Trunk movement is important to transfer energy efficiently during throwing and limited trunk motion increases reliance on the upper extremities [1]. The shoulder external rotator muscles have role of deceleration the throwing arm and ensuring stability of shoulder joint. Therefore, it is considered that trunk motion limitation lead to emphasize arm swing and increase traction stress on the shoulder external rotators. However, the relationship between trunk movement and the muscle activities of the shoulder external rotators is unclear. (Source: Gait and Posture)

O 076 - Gait and knee function in individuals with mild to severe knee osteoarthritis – A cross-sectional study
The Gait Deviation Index for kinematics (GDI) and kinetics (GDI-kinetic) summarizes overall ‘gait quality’ into a single score from a 3-dimensional (3D) gait analysis and have been reported to identify deviant gait in patients scheduled for total knee arthroplasty (TKA) [1]. The Single Limb Mini Squat test (SLMS) is a reliable test of knee function in individuals with knee OA and has p reviously been shown to be moderately associated with GDI-kinetic in patients scheduled for TKA. However, it is unknown if simple performance based measures like SLMS or measurements that includes quantitative 3D gait analysis may provid...

O 077 - Electromyography for determination of muscle response: Effects of Parkinson disease
Muscle response is a concept well-known in medicine or in rehabilitation and therapeutic exercise. With the development of ADAS system (Advanced Driving Assistance System), muscle response time as a part of driver reaction time has been investigated in the field of traffic and transport. One of possible approach how to determine muscle response is to use electromyography (EMG). It is often used in combination of electroencephalography (EEG) for determination of driver ’s behavior [1]. The aim of this study is to specify muscle response time of drivers and show how this parameter of driver's behavior can be affected by Pa...

O 088 - Evaluation of pre- and postoperative gait parameters after derotation osteotomy of the tibia taking into account the intraoperative derotation value
In case of persistent tibia rotational deformities (TTA) with functional constraints, surgical correction by tibial rotational osteotomy (TRO) is recommended. Previous works have been shown effects of TRO on certain gait parameters for patients with TTA [1]. Different fixation techniques are applied (plate fixation, k-wire, external fixator or pedi nail). The study by Geisb üsch et.al [2] showed that the intraoperative measurement and fixation of the plate could lead to a different degree of derotation than planned. (Source: Gait and Posture)

O 090 - Does the Powers ™ strap modify lower limb biomechanics during running in individuals with patellofemoral pain?
Abnormal biomechanics, especially dynamic knee valgus, a combination of femoral adduction, femoral internal rotation, external knee rotation, tibial abduction, and ankle eversion is known to be associated with patellofemoral pain (PFP) [1 –3]. To stabilise the patellofemoral joint during leisure and sporting activities by increasing the hip external rotation and hip abduction, researchers in the USA invented the Powers™ strap.

O 096 - How abnormal is normal? Stride-to-stride variability and effects of age on the gait of typically developing children
In the process of 3D gait analysis (3DGA) interpretation, gait deviations in children with cerebral palsy (CP) are identified through comparison with reference data of typically developing children (TD). Generally, TD-data are presented as group averages of numerous strides for different ages and walking velocities. It can be argued however, that comparing single strides of a patient to an averaged group is an unfair comparison, since averaging reduces natural inter-subject and stride-to-stride variation.

O 098 – Distinguishing the Influences of Increased Femoral Anteversion from Hypermobility during walking for neurologically intact individuals
Increased femoral anteversion (IFA) is a transverse plane problem that may lead to alterations on lower body kinematics during walking [1,2]. IFA and hypermobility syndrome are commonly seen together in healthy individuals [3]. Therefore, describing the pure effects of IFA related gait parameters is very difficult for children with hypermobility and IFA together. (Source: Gait and Posture)

O 109 - Post-treatment muscle coordination patterns during gait are highly similar to pre-treatment ones in CP children
Musculoskeletal models and computational simulations could be of help to clinicians in assessing the most appropriate treatment for a patient with Cerebral Palsy (CP) [1]. Simulations trying to predict the functional outcome face the challenge of defining a reliable model of the subject ’s motor control in the POST-treatment condition, with only the pre-treatment EMG patterns being available to inform about the patient’s control.

O 111 - Accuracy of the Conventional Gait Model: Preliminary results
The Conventional Gait Model (CGM) [1,2], distributed as Vicon Plugin gait (Vicon PiG) became a standard in the field of 3D Clinical Gait Analysis. Its reliability is assessed thought repeatability tests. On the other hand, accuracy of the CGM in terms of underlying bone motion has never been quantified. It ’s all the more important CGM outputs might orientate a patient towards bone surgery. Thanks to a consensus, data from invasive approaches are available in open-access [3]. They can serve as basis for model validation. (Source: Gait and Posture)

P 012 - Kinetic Changes of Pregnant Gait during Pregnancy and Post-partum
Pregnancy leads to anatomical and physiological changes, affecting the musculoskeletal system and showing changes movement characteristics. Body weight increases greatly in the trunk during fetus growth, which leads to physique changes. Previous studies showed that integrated changes during pregnancy increased falling risk for pregnant women. Also, they can take coral vacation 8 weeks legally in Japan. Surprisingly, they have to return to work within 2month while having body trouble. Thus, the motor system adjusts accordingly to compensate these changes to keep postural balance and gait stability.

P 021 – Hip-knee and knee-ankle interjoint coordination during short-track speed skating
In short-track speed skating, only a few studies have analyzed the three-dimensional (3D) kinematics of the lower limbs during cornering phases, although there were many studies on the kinematic characteristics of the long-track speed skating, and on the biomechanics of ice hockey skating. Kinematic parameters of the lower limbs during skating are generally presented as a function of time, such as graphs of joint angles versus time. However, conventional parameter-time graphs are not sufficient to quantitatively describe interjoint coordination in sport and daily activities. (Source: Gait and Posture)

P 027 - Feasability study of the use of silicon electrodes for EMG
This study is part of a wider project aiming at investigating the relative motion of the residual limb and the socket, the pressure inside the socket as well as the muscle activity in a population with transfemoral amputation. During prosthesis design one of the most important aspects is the proper fit between the residual limb and the socket. This relies mainly on the experience of the prosthetist[1]. One of the requirements for prosthesis is to provide suspension that is adhesive strength of the socket to the skin[2]. (Source: Gait and Posture)

P 035 - Kinematic Factors Generated Forward Propulsion in Wheelchair Marathon
Wheelchair marathon is one of the famous events of Paralympic. Additionally, wheelchair marathon is a type of sport that needs many skills and techniques because of their impairment or physical function. Some physiological factors might influence actual race time, such as cardiorespiratory endurance, muscular strength, and motivational level. However, there are few reports regarding the relationship between kinematic factors generated forward propulsion and race time. Therefore, purpose of this study was to investigate kinematic factors generated forward propulsion of wheelchair marathon. (Source: Gait and Posture)

P 060 - The impact of postural weakness on running kinematics in healthy children – Results of the Barefoot LIFE-study
A major challenge in the sensorimotor control of human locomotion is the destabilizing high-positioned mass of the trunk [1,2]. Upper body accelerations are mainly counterbalanced by lower limb muscles [2]. Paraspinal muscles attenuate the mechanical perturbations transmitted through the spine to the head, provide stiffness and resist trunk flexion [1,3]. In children, the high prevalence of postural insufficiency is a common problem [4,5]. However, publications studying the impact of associated trunk muscle weakness on sensorimotor control during running in children are still lacking. (Source: Gait and Posture)
