O 106 – Influence of ankle’s degree of freedom on muscle force estimation in different simulation environments
The main movements of the ankle joint are dorsi-, plantarflexion (DF/PF), eversion and inversion [1]. In musculoskeletal modelling of walking, the ankle is often simplified, e.g. restricting the degree of freedom (DoF) of the ankle joint [e.g., 2,3], which might lead to altered muscle force estimations. Different simulation environments use different standard anatomical models which complicates comparison between results [3]. (Source: Gait and Posture)

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 optical radiation to detect local changes of (de)oxyhemoglobin concentration in the cerebral cortex, like a fMRI. (Source: Gait and Posture)

P 056 - The effect of medication on walking turns in Parkinson disease
More than half of Parkinson ’s disease patients (PD) report difficulty in turning. We observed different numbers of turn steps, turn times, turn types, and turn qualities in PD patients compared to healthy adults. Although medication has an effect on motor impairments in PD, its effect on the complex walking turn task is sti ll unclear. The aim of this paper is to investigate the effect of medication on the walking turn. (Source: Gait and Posture)

P 143 - Plantarflexor strength in relation to vertical ground reaction force in terminal stance in children and adolescents with spastic cerebral palsy
Muscle weakness, most pronounced around the ankle [1], is an important cause of gait deviations in cerebral palsy (CP) [2]. Many children with CP experience significant problems supporting their bodyweight and decelerating the downward velocity of the center of mass in terminal stance [3]. This is reflected in a decreased second peak (FZ2) of the vertical ground reaction force (GRF) to less than 100% of bodyweight. The contribution of weak plantarflexor muscles has not been explored previously. A better understanding of which factors reduce FZ2 may help to use FZ2 for clinical decision making.
