Responsiveness and clinically meaningful improvement, according to disability level, of five walking measures after rehabilitation in multiple sclerosis: a European multi-center study Universiteit Hasselt Universiteit Antwerpen

Ilse BAERT, Jenny Freeman, Tori Smedal, Ulrik Dalgas, Anders Romberg, Helen Conyers, Iratxe Elorriaga, Benoit GEBARA, Johanna Gumse, Adnan Heric, et al.
Background. Evaluation of treatment effects on walking requires appropriate and responsive outcome measures. Objectives. To determine responsiveness of 5 walking measures and provide reference values for clinically meaningful improvements, according to disability level, in persons with multiple sclerosis (pwMS). Methods. Walking tests were measured pre- and postrehabilitation in 290 pwMS from 17 European centers. Combined anchor- and ...

Responsiveness and clinically meaningful improvement, according to disability level, of five walking measures after rehabilitation in multiple sclerosis: a European multi-center study Universiteit Hasselt

BACKGROUND: Evaluation of treatment effects on walking requires appropriate and responsive outcome measures. OBJECTIVES: To determine responsiveness of 5 walking measures and provide reference values for clinically meaningful improvements, according to disability level, in persons with multiple sclerosis (pwMS). METHODS: Walking tests were measured pre- and postrehabilitation in 290 pwMS from 17 European centers. Combined anchor- and ...

A GPS-based methodology to analyze environment-health associations at the trip level : case-crossover analyses of built environments and walking Universiteit Gent

Basile Chaix, Yan Kestens, Dustin T Duncan, Ruben Brondeel, Julie Méline, Tarik El Aarbaoui, Bruno Pannier, Juan Merlo
Environmental health studies have examined associations between context and health with individuals as statistical units. However, investigators have been unable to investigate momentary exposures, and such studies are often vulnerable to confounding from, for example, individual-level preferences. We present a Global Positioning System (GPS)-based methodology for segmenting individuals' observation periods into visits to places and trips, ...

Virtual reality—enhanced walking in people post-stroke: effect of optic flow speed and level of immersion on the gait biomechanics Vrije Universiteit Brussel KU Leuven

Emma De Keersmaecker, Anke Van Bladel, Silvia Zaccardi, Nina Lefeber, Carlos David Rodriguez Guerrero, Eric Kerckhofs, Bart Jansen, Eva Swinnen

Background: Optic flow—the apparent visual motion experienced while moving—is absent during treadmill walking. With virtual reality (VR), optic flow can be controlled to mediate alterations in human walking. The aim of this study was to investigate (1) the effects of fully immersive VR and optic flow speed manipulation on gait biomechanics, simulator sickness, and enjoyment in people post-stroke and healthy people, and (2) the effects of the ...

Effects of Rehabilitation on Gait Pattern at Usual and Fast Speeds Depend on Walking Impairment Level in Multiple Sclerosis Universiteit Hasselt

Carmela LEONE, Alon Kalron, Tori Smedal, Britt Normann, Inez WENS, Bert OP 'T EIJNDE, Peter FEYS
Background: Physical rehabilitation can improve walking capacity in persons with multiple sclerosis (MS). However, changes in spatiotemporal gait parameters after rehabilitation are not frequently evaluated, and it is unknown to what extent potential effects depend on baseline disability level. The objective was to investigate the effectiveness of rehabilitation programs on gait parameters at usual and fastest speeds in persons with MS ...

Assessment of transfemoral amputees using a passive microprocessor-controlled knee versus an active powered microprocessor-controlled knee for level walking KU Leuven

Veerle Creylman, Louis Peeraer
BACKGROUND: In transfemoral (TF) amputees, the forward propulsion of the prosthetic leg in swing has to be mainly carried out by hip muscles. With hip strength being the strongest predictor to ambulation ability, an active powered knee joint could have a positive influence, lowering hip loading and contributing to ambulation mobility. To assess this, gait of four TF amputees was measured for level walking, first while using a passive ...

Robot-assisted walking with the Lokomat: the influence of different levels of guidance force on thorax and pelvis kinematics Vrije Universiteit Brussel KU Leuven Universiteit Antwerpen

Eva Swinnen, Marc Michielsen
Background
Little attention has been devoted to the thorax and pelvis movements during gait. The aim of this study is to compare differences in the thorax and pelvis kinematics during unassisted walking on a treadmill and during walking with robot assistance (Lokomat-system (Hocoma, Volketswil, Switzerland)).

Methods
18 healthy persons walked on a treadmill with and without the Lokomat system at 2 kmph. Three different ...

Effects of feeding level, milking frequency, and single injection of cabergoline on feed intake, milk yield, milk leakage, and clinical udder characteristics during dry-off in dairy cows KU Leuven

Mona Larsen
Abrupt and gradual dry-off strategies by reducing feeding level (normal vs. reduced energy density), reducing milking frequency (twice vs. once daily), and administration of a dopamine agonist after last milking (i.m. saline vs. cabergoline injection) were investigated (2 × 2 × 2 factorial arrangement) for their effects on feed intake, milk yield, energy balance, milk leakage, and clinical udder characteristics in 119 Holstein cows. In the last ...
