In order to recruit neurons in excitable tissue, constant current neural stimulators are commonly used. Recently, ultra high-frequency (UHF) stimulation has been proposed and proven to have the same efficacy as constant-current stimulation. UHF stimulation uses a fundamentally different way of activating the tissue: each stimulation phase is...

Current methods to track the progression and evaluate treatment of muscular dystrophies are scarce. The electromechanical delay (EMD), defined as the time lag from muscle electrical activity to motion onset, has been proposed as a biomarker, but provides only limited insight in the pathophysiol-ogy of muscle function. This work proposes and...

This manuscript points out some mistakes in the Introduction and in the table of comparison of a paper already published in this journal by Hsu and Schmid [1]. Although the main claim of [1] is still preserved, we believe the paper needs to be rectified for scientific correctness of the work. In [1], the first High Frequency Switched...

Vestibular signals, which encode head movement in space as well as orientation relative to gravity, contribute to the ongoing muscle activity required to stand. The strength of this vestibular contribution changes with the presence and quality of sensory cues of balance. Here we investigate whether the vestibular drive for standing balance...

This thesis describes the design of the product-service combination called Move on. Move on is designed to stimulate adolescents to be more physically active. This stimulation is done by gamification, which therefore can be considered as serious gaming product. This thesis starts with a literature analysis of the decreasing level of childrens’...

Signal Analysis techniques are routinely used in Neuroscience to interpret raw signals harvested from the Nervous System. From a simple Fourier analysis to more complicated methods such as multiresolution wavelet analysis, such techniques must be used for signal manipulation in order to reach informed conclusions on the measurements taking place...

"The use of high-frequency stimulation for conduction block of the pudendal nerve has potentially high benefits for patients suffering from non-neurogenic urinary retention. Special care has to be put in the design of stimulation parameters to ensure safe operation and prevent electrode and tissue damage. While high-frequency conduction block...

To develop high enthalpy geothermal systems in the Netherlands, reservoirs with a depth greater than 4000 m need to be targeted. The Lower Carboniferous limestone is proposed as the main target due to its depth and wide occurrence. To investigate the potential of this formation, the physical rock properties are studied in a variety of laboratory...

The goal of the REValUE Project is to design a test device which is able to stimulate nerve tissue with current driven, high frequency stimulation in the range from 1 to 15 kHz and 1 to 10 mA. The test device will be used in research to pudendal nerve blockage. This thesis describes the design process of a safety module for this device. The...

Being ill, treatment at health centres causes anxiety and stress with children. This has a negative effect on their wellbeing, healing process and more important, their cognitive, motoric and social development. The goal of this thesis is to describe a set of generic properties for the built environment to reduce this negative effect by...

The goal of this Bachelor graduation project is to make an electrical stimulator that can be used to help people empty their urinary bladder. Patients that are unable to relax the urethral sphincter are most commonly treated by mechanically emptying the bladder or by sacral root stimulation where the roots are selectively cut. <br/><br/>The...

In the REstore Voiding Urinary rEtention (REValUE) project, a high frequency stimulator is designed that should be able to determine the optimal parameters to block the urethral sphincter. In this report the design of the control, interface, current source and electrode switching circuit of the device is explained – the other parts are explained...

Neurostimulators have been developed over the past few decades to treat various diseases, such as Parkinson’s disease, chronic pain, epilepsy, migraine and bladder dysfunction. One of the major design challenges is the selection of a powering method that could supply mW power levels to miniaturized implanted devices. Among several methods,...

By monitoring head movement and orientation in space, the vestibular system can evoke appropriate muscle responses in order to maintain standing balance. The present study investigates whether vestibular-evoked muscle responses are dependent on sensory cues of gravity by examining these responses across varying load and gravity conditions....

Background During Transcranial Magnetic Stimulation (TMS) experiments researchers often use a neuronavigation system to precisely and accurately maintain coil position and orientation. New method This study aimed to develop and validate an open-source software for TMS coil navigation. StimTrack uses an optical tracker and an intuitive user...

Standing balance relies on the integration of multiple sensory inputs to generate the motor commands required to stand. Mechanical and sensory perturbations elicit compensatory postural responses that are interpreted as a window into the sensorimotor processing involved in balance control. Popular methods involve imposed external...

Apnea of prematurity (AOP) is one of the most common diagnoses in preterm infants. Severe and recurrent apneas are associated with cerebral injury and adverse neurodevelopmental outcome. Despite pharmacotherapy and respiratory support to prevent apneas, a proportion of infants continue to have apneas and often need tactile stimulation, mask,...

Neck muscle activity evoked by vestibular stimuli is a clinical measure for evaluating the function of the vestibular apparatus. Cervical vestibular-evoked myogenic potentials (cVEMP) are most commonly measured in the sternocleidomastoid muscle (and more recently the splenius capitis muscle) in response to air-conducted sound, bone-conducted...

This paper presents the design of a neurostimulator performing biphasic ultra-high-frequency electrical stimulation while being driven from ultrasound energy. Unlike conventional constant current or constant voltage stimulators or state-of-the-art ultra-high-frequency stimulators, the system does not convert the input AC signal into regulated...

When the neural pathway within the spinal cord gets damaged, a person’s ability to initiate loco- motion can be affected. Currently, no restorative treatments exist for individuals that suffer from such an injury. However, recent studies have shown epidural spinal cord stimulation (ESCS) to be a potential option for re-establishing some...
