Late-cueing of gait tasks on an uneven brick surface impacts coordination and center of mass control in older adults
Walking requires the ability to navigate different surfaces and change direction, sometimes with little planning time, while controlling balance and body orientation. For older adults, uneven surfaces are among the environmental factors precipitating falls [1]. Falling during turning is 7.9 times more likely to lead to a hip fracture than during walking [2]. A better understanding of turning while walking (turning gait) over uneven surfaces with short planning time and the intrinsic factors that mediate performance is warranted given aging populations [3] and the economic burden of falls [4].

P 065 - Influence of equinus correction on mechanical advantage of the plantarflexors during gait in children with cerebral palsy
To walk, muscle forces must overcome the individual ’s body weight and resulting ground reaction forces (GRF). The relationship between muscle force and GRF depends on the mechanical advantage, which for the plantarflexors is determined by the ratio of external (GRF) to internal (Achilles tendon) moment arms about the ankle. Children with cerebral palsy (CP) often adopt an equinus gait pattern that reduces the external moment arm length. This is commonly treated surgically by calf-lengthening. However, the internal moment arm may also be smaller in children with CP [1]. (Source: Gait and Posture)

O 052 — Comparison of anatomical Tibia-Hindfoot-Alignment and Oxford-Foot-Model marker-set measurement in weight bearing CT - effect of adjustment in the static model
Oxford-Foot-Model (OFM) is commonly used in assessment of pathological foot gait in 3D gait analysis [1] and has been tested for repeatability [2], but still lacks validity [1]. Full weight bearing CT (WBCT) allows 3D imaging in standing position, not influenced by beam projection and/or foot orientation [3]. To our knowledge no comparison study with the OFM marker-set in a 3D-full weight bearing imaging and its influence of marker correction to the static OFM has been published.

P 022 - Loading characteristics of anterior cruciate ligament in target-side knee during golf swing
The combination joint kinematics and kinetics during golf swing suggested that the soft tissue structure of the knee resisting joint compression and internal rotation at low flexion angle may be susceptible for target-side knee injury. Therefore, an anterior cruciate ligament (ACL) rupture is one of the potential injuries that may occur from excessive and repeated stress resulting from the golf swing. In our previous study [1], we estimated the maximum ACL force of the target-side knee during golf swing as 841.8 ± 437.1 N and the result revealed that fatigue life of ACL could be several thousand.

P 032 - A sensitivity analysis of kinematic variables in females with patellofemoral pain performing seven functional tasks
Little is known about how the variables derived from body segments can contribute or misrepresent the data extracted in a kinematic analysis [1]. Identifying the respective influence of variables may guide the acquisition and interpretation of kinematic data, as well as improve the efficiency of clinical decision making.

P 038 – Effect of haptic sensory input from the wearing of cloth on gait performance
Lightly touching the fingertips to a stable external object (level of force is insufficient to mechanically support one ’s own body) results in decreased postural sway during standing. This “light touch” phenomenon suggests that haptic input through touching primarily provides information about the body orientation, and contributes to balance control [1]. Although the effects of light touch are of interest to r esearchers, it is unusual for individuals to lightly touch objects while performing daily activities. (Source: Gait and Posture)

P 039 - Muscle fatigue during a short walking exercise in children with cerebral palsy who walk with a jump gait
Short walking exercise results in gait adaptations [1] and neuromuscular fatigue in children with bilateral cerebral palsy (BCP) who walk with a crouch gait [2]. It was suggested that the fatigue highlighted at the rectus femoris (RF) and gastrocnemius lateralis (GAL) muscles was related to the flexed posture maintained throughout the gait cycle. Jump gait, another common gait pattern in BCP, is characterized by an excessive knee flexion at initial contact, but near normal knee extension during stance. (Source: Gait and Posture)

P 046 – Difference in gait profile index between groups of a gait classification for adult patients with hemiparesis in chronic phase
A recent classification of adult patients with hemiparesis has been proposed [1], on the basis of key abnormalities observed whilst walking. This classification consisted of 3 groups divided in 2 sub-groups. Their definitions were based 1) on observed ankle, knee and hip kinematic abnormalities, and 2) on flexor muscles strength assessed during clinical examination. On the other hand, the Gait Profile Score (GPS) has been proposed in clinical gait analysis (CGA) to quantify the pathology ’s impact on gait pattern based on kinematics [2], and its minimal clinically important difference (MCID) has been defined [3].

P 074 - A comparison of foot kinematics in children with clubfeet and healthy controls using the Oxford Foot Model
The clubfoot is characterized by an equinovarus foot and exists of a three-dimensional deformity namely equinus, varus and adduction (1, 2). Nowadays the Ponseti method is the preferred treatment for clubfeet, aiming to achieve a normal appearing, functional and painless foot (3-5). Foot function, residual deviations in gait or possible relapses in clubfeet patients can be assessed with 3D gait analysis (6-12). However, most studies applying gait analysis focused on the entire foot instead of using a multi-segment foot model while comparing gait kinematics of clubfoot patients to healthy controls.

P 079 - How does load transfer with weight increase in children: A 3-year follow-up study
In an attempt to better understand several dysfunctions, musculoskeletal complications associated with childhood obesity, many studies have investigated the effects of obesity on plantar pressure distribution, foot structure [1], with the result indicating higher plantar pressure, flatter feet in obese children. But how does the dynamical force transfer when children obtain their weight? The way of force transference in feet, the transfer mechanism is still unclear. (Source: Gait and Posture)

Parkinson's disease versus ageing: different postural responses to soleus muscle vibration
Parkinson's disease (PD) is a common neurodegenerative disease that becomes increasingly prevalent with age [1]. Impaired balance predisposes 68% of PD patients to fall at least once a year [2]. Moreover, the risk of falls increases gradually with disease progression [3]. (Source: Gait and Posture)

Association of Altered Frontal Plane Kinematics and Physical Activity Levels in Females with Patellofemoral Pain
Patellofemoral pain (PFP) is a common lower extremity injury that is characterized by patellar pain during activity. Individuals with PFP often present with knee pain during weight-bearing tasks [1]. PFP is a difficult condition for clinicians and patients alike, as the majority of these patients report pain for multiple years following both diagnosis and bouts of conservative treatment [2]. This chronic pain may result in a variety of negative complications in both quality of life and functional limitations [3]. (Source: Gait and Posture)

P 024 - Near-infrared spectroscopy patterns of cortical activity during gait in Parkinson ’s disease patients treated with DBS STN
Disorders of gait seriously affect the functional state and quality of life of patients with Parkinson ’s disease (PD). Impaired brain function underlies disorders of movement control in PD, however functional brain imaging with magnetic resonance (fMRI) is not feasible during gait. Near-Infrared Spectroscopy (NIRS) is a portable imaging method for measuring brain activity. It uses low-energy optic al radiation to detect local changes of (de)oxyhemoglobin concentration in the cerebral cortex, like a fMRI. (Source: Gait and Posture)
