P 085 - Walk to run transition in children with cerebral palsy
Walking patterns and their strategies are already well known in children with cerebral palsy (CP) [1]. On the other hand, literature about walk to run transitions as well as running is still limited [2]. These are considered higher mobility skills and allow a greater participation of the children in their environment as well as in school and recreational playground activities. A better understanding about transitions between walking and running may give new important advices for the physical rehabilitation, whose ultimate purpose is to increase the participation in the social life [3].

Timed Up and Go test and wearable inertial sensor: Combining tool to assess mobility in a child after orthopedic surgery
Cerebral palsy (CP) is a permanent disorder of movement and posture, causing activity limitation, attributed to non-progressive disorders that occurred in the developing fetal or infant brain [1,2]. The necessity to increase the specificity and sensitivity of the test for the quantification of age-related performance in mobility, balance and overall function - led to the introduction of wearable and mobile technologies, that associated with validated tests, such as the Timed Up and Go test (TUG), can provide also information about the kinematics of the functional tasks, including accelerations, and angular velocities, and ...

P 121 - Instrumenting the clinical examination: A proof of concept study
During standard clinical 3D gait analysis, retro-reflective markers are placed on anatomical landmarks to allow kinematic modelling of the lower limb. To interpret this data however, information from a clinical examination is also required, in order for primary and secondary causes of gait deviations to be determined. Clinical examinations commonly require two clinicians, one manipulating the limb, the other measuring joint ranges of motion (ROM) using goniometry, with reliability of ≤10° accepted within and between assessors [1].

P 127 - A pilot study of forward bending, lateral flexion and axial rotation of the spine in healthy subjects
The actual Gold Standard for spine assessment are x-rays, even if they just give a static view of the spine.Currently there are no accurate methods to thoroughly asses spine mobility in clinical practice: this is normally evaluated by physicians and therapists only observationally, and sometimes with a total Range of Motion (ROM) measurement. Through optoelectronic systems it ’s possible to have an objective dynamic analysis of the spine during movement. The data collected would allow a measure for an objective and standard assessment of the spine.[1,2] (Source: Gait and Posture)

Transtibial Amputee Gait during Slope Walking with the Unity Suspension System
Prosthetic socket suspension systems affect gait, balance, satisfaction, and quality of life, and therefore, is an important step in prosthetic rehabilitation [1 –5]. Previous studies indicated that vacuum assisted suspension system (VASS) can improve gait symmetry, proprioception, and satisfaction compared to other suspension systems due to an enhanced connection between residual limb and socket [2,3,6–12]. VASS use a mechanical or electric pump to acti vely remove air between the liner and socket, while suction systems use a passive one way valve to expel the air. (Source: Gait and Posture)

P 148 - Synergy complexity during maximal voluntary isometric contractions
Non-negative matrix factorization (NNMF) has been used in dynamic and static tasks to identify muscle synergies [1,2]. From NNMF, complexity of motor control of a given task can be assessed by calculating total variance accounted for by one synergy (tVAF1). tVAF1 of gait was found to be increased in children with cerebral palsy (CP) when compared to typical developing (TD) children [3]. However, we expect that tVAF1 of maximal voluntary isometric contractions (MVICs) will be higher in TD children, since MVIC outcomes depend on selectively activating one muscle group.

P 150 – Assessment of functional tasks related to the risk of falling in people with Alzheimer
Due to the instability and gait impairment in Alzheimer ’s patients [1], some approaches to the risk of falling assessment have been conducted. There are several reliable and valid scales to assess it as the Falls Risk assessment score [3], but the cognitive impairment, that affects their remembrance ability, hampers the possibility of using this kind of approach. Instead, the assessment requires objective tools that analyses different daily living activities related to the mobility as Berg scale [4,5] or Timed Up and go [6,7]. (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)

P 166 - Use of 3D Gait Analysis to Measure Clinical Outcome in a Stiff Person Syndrome
Stiff Person Syndrome (SPS) is an autoimmune movement disorder that leads to a local or generalized increase in muscle tone. Patient with SPS usually also shown painful spasm, hyperreflexia, and elevation of serum anti-glutamic acid decarboxylase (anti-GAD) antibodies [1]. Anti- GAD antibodies probably play a central role in causing the disease, but precise mechanisms remain unknown [1]. Actually, data on disease natural history are poor, treatments are yet unstandardized [2] and there aren ’t reliable and accurate outcome measures to use in clinical trials [3].

P 172 - Pre-compressing springs in orthotic ankle joints enhance the effect of a dynamic dorsiflexion stop on patients with weak plantar flexors
Lower limb orthoses with a defined dorsiflexion stop can restore gait symmetry and improve important gait parameters in patients with weak plantar flexors [1]. Modern commercial ankle joints allow motion in plantarflexion as well as in dorsiflexion. In that way, the muscular dynamics of late stance can be used to come closer to a physiological gait. Accordingly, for an effective dorsiflexion stop, the dorsiflexion resistance exerted by the ventral spring unit must be sufficient to activate the forefoot lever from the neutral alignment of the orthosis to a dorsiflexion of 5 °.

P 177 - The Infraspinatus Muscle Activity during Throwing Motion in Baseball Player with Throwing Injury
The baseball player is exposed to excessive and repetitive stresses for their shoulders of throwing side. During pitching, the infraspinatus is placed under extreme eccentric demand and is vital in dissipating excessive forces exposing them to overload [1]. These injuries result in a decline in performance and longtime absence from sport participation. Therefore, many authors have emphasized the need appropriate infraspinatus activity during throwing motion. However, infraspinatus activity during throwing in baseball player with throwing injury was unclear. (Source: Gait and Posture)

Walking with an induced unilateral knee extension restriction affects lower but not upper body biomechanics in healthy adults
Prolonged immobilization or scarring after injuries often leads to structural changes of the fibrous joint tissue, which may result in contractures of the respective joint [1]. At the knee, the most likely causes for contractures are major trauma, arthritis, and knee surgery [2]. The usual resting position for a swollen knee is about 30 ° of flexion [3], which is why this position is characteristic for knee contractures in orthopedic rehabilitation. Contractures often interfere with the usual movement pattern and can therefore lead to passive and/or active secondary gait deviations [4]. (Source: Gait and Posture)

Age-related changes in arm motion during typical gait
Typically developing infants acquire the ability of independent walking around the age of 12 –18 months [1]. At the beginning, toddlers walk with the arms in a fixed posture of shoulder abduction and elbow flexion, a position known as ‘high guard’, only present during the first months of walking (rapid development phase) and soon developing into a reciprocal arm swing [1–3]. To the best of our knowledge, there have been no attempts to describe age-related changes in arm movements during the following, slower development. (Source: Gait and Posture)
