O 077 – Electromyography for determination of muscle response: Effects of Parkinson disease
Nowadays muscle response constitutes one of the important topic in the field of medicine and rehabilitation. For rehabilitation purposes muscle response time can be analyzed by using electromyography. With the development of ADAS system, muscle response time can be determined as a part of driver reaction time for purposes of traffic analyzes and assessments. The aim of this work is to analyze muscle response within two investigated groups of drivers, i.e drivers suffering by Parkinson disease (PD drivers) and drivers without Parkinson disease (NON-PD drivers).

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 rotationaldeformities (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 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). 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.

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 movementcharacteristics. 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 [1]. 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 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)

P 163 – Validation of the Foot Profile Score
The Gait Profile Score (GPS) gives a single measurement of an individual ’s gait pattern. It is the average root mean square (RMS) difference between a patient’s and normative data [1]. The GPS includes the traditional measurement of the foot as a single rigid segment in two-dimensions. The Oxford Foot Model (OFM) was designed to measure tibia, hindfoot, forefoot and hallux motion in three dimensions [2]. The Foot Profile Score (FPS) is a single number, designed to be the equivalent of the GPS, based on OFM kinematics. (Source: Gait and Posture)

O 046 – A flexible omnibus matching algorithm (FOMA) to support treatment decisions for children with cerebral palsy
Treatment outcomes among children with cerebral palsy are mediocre, unpredictable, and stagnant over several decades. We use a nearest-neighbors matching algorithm to predict outcomes from individuals. The algorithm allows clinician input regarding the relevant matching parameters, treatment of choice, and outcome of interest. The algorithm was tested on 1092 limbs that underwent single-event multi-level surgery. Predictions compared favorably to previous regression-based approaches, producing smaller root mean squared errors across the spectrum of kinematics. (Source: Gait and Posture)

O 035 - A novel method to measure step width during the swing phase of gait
Gait disorders are common in patients with neurological or muskuloskeletal disorders. Parkinson ’s disease, multiple sclerosis and hydrocephalus are examples of neurological diseases where impaired gait is a typical symptom. The gait pattern is often diagnose specific and gait analysis can therefore guide the physician when diagnosing a patient. Patients with normal pressure hydrocephalus (N PH) for example, typically have a broad-based, shuffling and short-stepped gait. Clinically, gait is commonly visually assessed using different rating scales. (Source: Gait and Posture)

O 046 - A flexible omnibus matching algorithm (FOMA) to support treatment decisions for children with cerebral palsy
Predicting treatment outcomes for children with cerebral palsy (CP) is a "holy grail" of clinical gait analysis. Researchers have focused on modeling techniques like linear regression and machine learning. These approaches work, but they suffer from several impediments to adoption. First, due to limitations in their statistical expertise, clinicians are skeptical of results produced by models. Second, these approaches minimize the clinician's input and fail to leverage their expertise, causing further alienation. (Source: Gait and Posture)

P 096 - Differences in postural stability in the elderly: Not all tests measure the same
Measurements of the center of pressure (CoP) acquired with a person positioned on a force plate is one of the most commonly used tool to investigate a balance. Several studies show a significant degradation of the body stability after the age of 60 years, [1,2], however, these conclusions were based on a limited number of indicators. Also, these studies don ’t take into consideration the change in stability in very old age groups and sex of subjects. (Source: Gait and Posture)

O 059 - Femoral deformities affect gait performance more than hip muscle weakness
In children with Cerebral Palsy (CP) bony deformities, specifically increased femoral anteversion (FA) and neck shaft angle (NSA), in combination with weak hip muscles are very common [1]. Currently, the relative impact of bony deformities and muscle weakness on gait performance is unknown. (Source: Gait and Posture)
