Background: Differential learning (DL) is a motor learning method characterized by high amounts of variability during practice and is claimed to provide the learner with a higher learning rate than other methods. However, some controversy surrounds DL theory, and to date, no overview exists that compares the effects of DL to other motor learning me...

Background Generalized joint hypermobility is defined as an excessive range of motion in several joints. Having joint hypermobility is not a pathology, but when associated with pain and other symptoms, it might affect health and function. Evidence for physiotherapy management is sparse and resistance training might be a possible intervention. Thus,...

Two simulation experiments are presented to gauge the accuracy of a new inverse kinematics method based on Bayesian inference (BIK; Pataky et al., 2019, J Biomech) in more realistic models than were considered previously. The first application concerns planar kinematics in the presence of soft-tissue artefacts and the second application concerns ri...

Specificity (SP) and sensitivity (SE) answer the question ‘what is the chance of a positive or negative test in response to the presence or absence of a clinical condition?’. Related to SP and SE are the diagnostic procedures of SNOUT and SPIN. SNOUT is the acronym for ‘Sensitive test when Negative rules OUT the disease’, SPIN for, ‘Specific test w...

The preferred intervention for treating patients with chronic nonspecific back pain, is active resistance training. Whole body Electromyostimulation (WB-EMS) is becoming increasingly popular as efficient training method. Therefore, applying this kind of training seems logical in patients with chronic unspecific back pain. In this ongoing prospectiv...

The objective of the current study was to explore the potential of dynamic computed tomography to detect kinematic changes, induced by sequential sectioning of the lateral collateral ligaments of the ankle, during full motion sequence of the talocrural joint. A custom-made device was used to induce cyclic controlled ankle inversion movement in one...
Chapter
Robot-assisted gait rehabilitation improves gait- and balance related outcome measures, but its merit over other gait rehabilitation methods is still insufficiently proven. The trunk and pelvis are important to maintain balance during gait. Despite, scarce research has been presented concerning the importance of the trunk and the pelvis in differen...

Surface electromyography is often used to assess muscle activity and muscle function. A wavelet approach provides information about the intensity of muscle activity and motor unit recruitment strategies at every time point of the gait cycle. The aim was to review papers that employed wavelet analyses to investigate electromyograms of lower extremit...

The proximal-to-distal sequence has previously been discussed in the light of performance and injury prevention. Sports biomechanics literature in general, and in team handball in specific, has claimed to be of importance to inform coaches on what constitutes a ‘good’ technical performance. However, hitherto no prospective studies exist on how this...

In this study, we examine the structure of postural variability in six elite-level recurve archers using the uncontrolled manifold concept. Previous research showed equivocal results for the relationship between postural control and shooting accuracy, but these studies were mainly limited to a descriptive approach to postural variability/stability...

INTRODUCTION: The preferred intervention for treating patients with chronic nonspecific back pain, according to the German National Care Guideline, is active exercise and to establish regular exercise in daily life. The lifestyle of patients with chronic nonspecific back pain mostly does not include any sports. They also often suffer from limitatio...
Article
Hysteresis in the coordination of movement can be described in the language of coordination dynamics as an asymmetrical response of a system's order parameter with respect to opposite changes in a control parameter. For movement tasks involving a large number of active degrees-of-freedom, the order parameter can be modelled with a pattern recogniti...

Purpose: Stress urinary incontinence (SUI) symptoms can be provoked during impact loads such as vertical jumps. To investigate and compare pelvic floor muscle (PFM) activity in women with SUI and continent women (CON) during drop jumps (DJ) and counter movement jumps (CMJ) could clarify the activity of the PFMs during impact loads. Methods: A tr...

Surface Electromyography (sEMG) is used in the evaluation of muscle activation patterns during body movements. Artefacts in sEMG-signals and analysis are caused by the movements of the cables between the sensor and electrode. Hence, there already exist some pre-amplified and wireless sEMG electrodes. These deliver black box devices to end users, fo...

Introduction Le renforcement musculaire est utilisé en physiothérapie chez différents patients, par exemple pour le mal de dos et l’arthrose. La question se pose également en termes économiques : dans quelle mesure les patients doivent-ils être intensivement suivis pour suivre un entraînement efficace ? Il n’existe actuellement que très peu d’étude...

Introduction On sait peu de choses des personnes qui présentent une hyper-mobilité générale des articulations. Elles sont souvent soumises à des restrictions au sport ou au travail du fait de douleurs ou d’un handicap. Une force musculaire adéquate pour contrôler le mouvement pourrait permettre de surmonter ces restrictions. L’entraînement en résis...

How humans maintain balance and change postural control due to age, injury, immobility or training is one of the basic questions in motor control. One of the problems in understanding postural control is the large set of degrees of freedom in the human motor system. Therefore, a self-organizing map (SOM), a type of artificial neural network, was us...

Introduction and hypothesis: Investigating the activity of the pelvic floor muscles (PFMs) in women during impact activities such as jumping, running or coughing may elucidate different aspects of PFM activation and therefore clarify the pathophysiology of stress urinary incontinence (SUI). A systematic review (PROSPERO 2016:CRD42016035624) was co...
Article
The proximal-to-distal sequence is a phenomenon that can be observed in a large variety of motions of the upper limbs in both humans and other mammals. The mechanisms behind this sequence are not completely understood and motor control theories able to explain this phenomenon are currently incomplete. The aim of this narrative review is to take a t...
Article
Aims: Impact activity like running is associated with an increase in intra-abdominal pressure which needs to be sufficiently countered by pelvic floor muscle (PFM) activity to secure continence. The aim of this study was to investigate and compare PFM kinematics in continent and incontinent women during running. Methos: Three-dimensional positio...

Background: Little is known about the management of persons with generalized joint hypermobility (GJH). Affected persons are often restricted in performing sports or leisure activities, as well as during work, due to pain and disability. Adequate muscle strength for movement control might be an important issue to overcome these restrictions. Resist...

Self-Organizing Maps (SOMs) are steadily more integrated as data-analysis tools in human movement and sport science. One of the issues limiting researchers’ confidence in their applications and conclusions concerns the (arbitrary) selection of training parameters, their effect on the quality of the SOM and the sensitivity of any subsequent analyses...

Background: Pelvic floor muscle (PFM) training is effective and recommended as first-line therapy for female patients with stress urinary incontinence (SUI). However, standard PFM physiotherapy concentrates on voluntary contractions although the situations provoking SUI require involuntary fast reflexive PFM contractions. To date, the focus of rese...
Conference Paper
Full-text available
Background: Pelvic floor muscles (PFM) must be able to contract reflexively given that sneezing and coughing provoke an expeditious intra-abdominal increase in pressure, whereupon PFM must react. Furthermore, reflex activity is also needed during whole body movements with a high impact load such as running or jumping. Consequently, a better underst...

Fast recovery after strenuous exercise is important in sports and is often studied via cryotherapy applications. Cryotherapy has a significant vasoconstrictive effect, which seems to be the leading factor in its effectiveness. The resulting enhanced recovery can be measured by using both objective and subjective parameters. Two commonly measured su...
