P 094 - Sit-to-stand of rheumatoid arthritis post-menopausal women vs. healthy post-menopausal – antero-posterior displacement of centre of gravity and centre of pressure
Sit-to-stand (STS) ability is essential for daily life. The reliability of ground reaction forces parameters during STS was studied [1] and STS stabilization could differentiate elderly who had past fall events [2]. Rheumatoid arthritis (RA) patients presented an increased fall risk [3], and the lower muscle strength [4] and the increased disability [5] yielded by these patients may lead to falls during STS events [2,6]. The relation established between centre of gravity projection (CoGP) and centre of pressure (CoP) is a critical parameter during STS [6]. (Source: Gait and Posture)

P 093 - Comparison of three bipedal tasks to quantify contribution of proprioception to postural stability in healhty children and adolescents
Static postural sway can be quantified as variation in body ’s center of force (COF) position across time using force or plantar pressure plates. Control of posture relies on visual, vestibular and somatosensory afference. In the somatosensory modality, both tactile and proprioceptive (“movement sensors”) afference are involved. Postural stability deve lops during childhood and adolescence, but is likely not matured at age of 14 years [1]. The role of proprioception for the postural control in developing system is largely unknown. (Source: Gait and Posture)

P 109 - Changes in leg alignment after total hip replacement detected with the EOS system
Goal of a total hip replacement (THR) is to reduce pain and improve quality of life. The THR should not change the morphology too much, in respect to the situation before surgery as well as to the contralateral leg. To receive reliable information about the leg alignment before and after THR, a measurement method with minimal systematic errors needs to be chosen. Radiographic measurements of the leg alignment are highly influenced by the positioning of the leg, leading to potential measurement errors [1]. (Source: Gait and Posture)

P 110 - Lower limb muscle volume estimation from maximum cross-sectional area and muscle length in cerebral palsy and typically developing individuals
Deficits in muscle volume may be a significant contributor to physical disability in children with cerebral palsy (CP). 3D measurements of muscle volume using MRI or 3D ultrasound may be difficult to make routinely in clinic. 2D ultra-sound may be a more convenient imaging technique as previous studies reported that muscle volume can be estimated based on this technique. Measurements of muscle thickness or anatomical cross-sectional area have been used to estimate muscle volume and strong linear relationships between muscle volume and the product of anatomical cross-sectional area and muscle length have been reported [1,2]...

P 117 - Improving effect of enhanced axial rehabilitation on trunk control deficit in children with cerebral palsy
In children with cerebral palsy (CP) most of therapeutics focus on lower limb disorders and gait. However, these children show trunk control deficits in static and dynamic situations that can affect daily life [1]. Recently, Heyrmann et al. [2] showed in CP children trunk control deficit in sitting posture as measured by the Trunk Control Measurement Scale (TCMS) and made the link between this deficit and trunk deviations during walking.

P 124 - Normative data to assess the degree of normality in the cervical spine movement replacing the outdated AMA guidelines. Preliminary results
The functional issues that befall the injury are a tangible sign that can be measured to assess the grade of severity, nevertheless reference values are needed to determine what is deviant from normality. Classically this has been done using the AMA guidelines for range of motion (ROM). Loses of between 4 º- 6º of cervical range of motion (ROM) for each life decade [1] suggest that AMA guidelines might not be sensitive enough to grade the injury depending on the patient’s age.

Stereotypes in static load and minimal motor activity which is typical for sedentary jobs often result in low back pain (LBP). Complex motor rehabilitation focused on ergonomic sitting with decreased static load could have a positive influence on performance part (musculoskeletal system) and on control part (central nervous system) of motor system.

P 140 - Assessment of angular momentum in patients with cerebral palsy, having excessive lateral trunk Motion, during walking
Angular momentum (AM) is a conservative controlling variable governing in complex dynamic system such as walking with the aim of maintaining dynamic equilibrium. [1] Harmonic ratio index (Hr), as a ratio of symmetry to asymmetry phases due to the trunk acceleration during walking, helps to measure the smoothness of walking. [2] The higher numbers of Hr in vertical and sagittal planes indicate on more stable, better balance and harmonic gait. (Source: Gait and Posture)

P 142 – Plantar pressure distributions in patients with chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) is associated with a limp, a shuffle or other walking abnormalities which are appeared parallel with COPD severity. One of the possible explanation of these reported disorders during walking could be related with poor peripheral muscle strength which is commonly seen in this population. It is not only led to disturb biomechanical aspects of normal walking, it may also alter plantar pressure distribution which is essential for proper co-contraction mechanisms of lower extremity muscles [1 –3].

Reliability of the variables measured with an Android device during a modified timed up and go test in patients with Alzheimer ’s Disease
The alteration of the frontal cognitive capacities, mainly the executive function, reduces the allocation of attentional resources in the brain, which compromises the gait stability and postural control, increasing the risk of falls [1,2]. For this reason, it is important to have tools that objectively assess these tasks in people with Alzheimer disease (AD). Further, the evaluation is essential to be objective since the recall required to answer questionnaires may be altered. The main objective is to analyze the reliability of the variables calculated with a system based in an Android device in the performance of a modifi...

P 155 – Normative dataset for the sensory organization test: Do we need sport-specific reference levels for athletes?
Sensory Organization Test (SOT) is a widely accepted gold-standard test for assessing postural control during quiet standing, providing valuable information about sensory integration of visual, somatosensory and vestibular systems.Current evidence suggests that physical activities (including sports) enhance postural stability in both elderly and athletes. Accordingly, it has been hypothesized that highly skilled movements involving postural control may lead to improvements in balance. Experimental findings, however, are contradictory, as sensory-motor skills are task-specific and may not be extended to upright stance. (Sou...

P 158 - A method to estimate passive mechanical properties of the soleus and gastrocnemius aspects of Achilles tendon
It is well known that some tendons exhibit important elastic and time-dependent characteristics that influence the function of the overall muscle-tendon complex [1]. Achilles tendon (AT) comprises of 3 subtendons arising from the soleus (SOL) and the lateral (LG) and medial (MG) heads of the gastrocnemius. Whether the mechanical properties differ in these subtendons are not clear. Therefore, this study aims to quantify subject-specific passive mechanical properties of MG and SOL aspects of the AT in vivo, respectively. (Source: Gait and Posture)

P 159 - Gait in stroke patients is influenced by upper limb functioning: a quantitative analysis correlating QuickDASH with Instrumented TUG and 10MWT
Loss of mobility after stroke is one of the main target of intervention in PRM and physiotherapy as motor impairment affects gait efficacy and upper limb function [1,2]: it is possible to observe a consensual improvement of these latter aspect throughout rehabilitation. Neural connections between upper and lower limb in gait are known [3,4] as well as the fact that modifications of upper limb movement during gait can affect gait parameters [5]. A recent review supports the inclusion of arm activity in addition to leg activity as a component of gait retraining after neurotrauma [6]. (Source: Gait and Posture)

Non-linear analysis of trunk movement of Air Defense Staff: Pilot study
Measurements of acceleration of a person ’s body segment by wearable MoCap system is one of the most commonly used tool to investigate a movement activity. However, this method to measure movement activity has not yet been used for the assessment of the air defense staff members. Existent studies do not compare the change in movement act ivity during shift work and depending on air traffic density. The aim of this study was to assess the ability of the trunk movement activity assessment by non-linear method to identify and differences in traffic density and hours of shift work.
