Reliability of 3D freehand ultrasound to assess lower limb muscles in children with spastic cerebral palsy and typical development Universiteit Gent KU Leuven
This study investigated the reliability of 3-dimensional freehand ultrasound (3DfUS) to quantify the size (muscle volume [MV] and anatomical cross-sectional area [aCSA]), length (muscle length [ML], tendon length [TL], and muscle tendon unit length [MTUL]), and echo-intensity (EI, whole muscle and 50% aCSA), of lower limb muscles in children with spastic cerebral palsy (SCP) and typical development (TD). In total, 13 children with SCP (median ...
Unraveling the molecular basis of the dystrophic process in limb-girdle muscular dystrophy LGMD-R12 by differential gene expression profiles in diseased and healthy muscles Universiteit Gent Vlaams Instituut voor Biotechnologie KU Leuven
Limb-girdle muscular dystrophy R12 (LGMD-R12) is caused by two mutations in anoctamin-5 (ANO5). Our aim was to identify genes and pathways that underlie LGMD-R12 and explain differences in the molecular predisposition and susceptibility between three thigh muscles that are severely (semimembranosus), moderately (vastus lateralis) or mildly (rectus femoris) affected in this disease. We performed transcriptomics on these three muscles in 16 male ...
Skeletal Muscles of Patients Infected with SARS-CoV-2 Develop Severe Myofiber Damage upon One Week of Admission on the Intensive Care Unit Universiteit Hasselt
Many critically ill patients infected with SARS-CoV-2 have been submitted to an intensive care unit (ICU). Patients with a SARS-CoV-2 infection that survive critical illness are confronted with months of physical impairments. To maximize recovery, it is important to understand the musculoskeletal involvement in critically ill patients infected with SARS-CoV-2. The aim of the present study was to assess the myocellular changes in SARS-CoV-2 ...
Overview of the Lucy Project: Dynamic Stabilization of a Biped Powered by Pneumatic Artificial Muscles Vrije Universiteit Brussel
This paper gives an overview of the Lucy project. What is special is that the biped is not actuated with the classical electrical drives, but with pleated pneumatic artificial muscles. In an antagonistic setup of such muscles both the torque and the compliance are controllable. From human walking there is evidence that joint compliance plays an important role in energy-efficient walking and running. To be able to walk at different walking speeds ...
A Novel Model For Emotion Detection From Facial Muscles Activity Vrije Universiteit Brussel
Considering human’s emotion in different applications and systems
has received substantial attention over the last three decades. The main approach
to cope with emotion detection is first extracting different features and then applying traditional machine learning approaches like SVM to find the true class.
However, recently proposed Deep Learning (DL) based models outperform traditional machine learning approaches.

Muscles involved in foot eversion movements during the swing phase of gait - some comparative-anatomical and functional-morphological aspects Universiteit Hasselt
In primate predecessors, various muscles might be involved in guaranteeing foot eversion at touchdown. In bipedal primates, e.g. humans, the strength of the peroneus muscles may be trained, in order to guarantee stable foot positioning at touchdown. Evertor muscles reinforcement might thus be used to prevent inversion traumatisms.
Propulsion system with pneumatic artificial muscles for powering ankle-foot orthosis Vrije Universiteit Brussel
The aim of this paper is to present the design of device for
control of new propulsion system with pneumatic artificial muscles. The
propulsion system can be used for ankle joint articulation, for assisting
and rehabilitation in cases of injured ankle-foot complex, stroke patients
or elderly with functional weakness.
Proposed device for control is composed by microcontroller, gener-
ator for muscles ...

The Safety of a Robot Actuated by Pneumatic Muscles — A Case Study Vrije Universiteit Brussel
In situations where robots share their workspace with humans, and where physical human-robot interaction is possible or even necessary, safety is of paramount importance. This paper presents a study of the safety of a lightweight robot actuated by pneumatic muscles. Due to its low weight, it has excellent hardware safety characteristics. In spite of this, it is shown that the system can be unsafe when under PID control. It is also shown that ...
Motor fatigability in persons with multiple sclerosis : Relation between different upper limb muscles, and with fatigue and the perceived use of the arm in daily life. Universiteit Hasselt
Background Motor fatigability is increasingly acknowledged in persons with MS (pwMS). It is unknown whether fatigability is generalized across upper limb muscles and relates to fatigue and perceived difficulties in upper limb use. Methods This observational case-controlled study included twenty PwMS (median EDSS = 3, range 1.5–6.5) and twenty healthy controls who performed 30″ sustained maximal muscle contractions for index finger abduction, ...
