effects of long term resistance training and simultaneous Electro Stimulation on muscle strength and functional mobility in multiple sclerosis
Multiple Sclerosis Journal, 2011Co-Authors: Tom Broekmans, Geert Alders, Ine Hanssen, Machteld Roelants, Peter Feys, Domien Gijbels, Piet StinissenAbstract:Background: Resistance training studies in multiple sclerosis (MS) often use short intervention periods. Furthermore, training efficiency could be optimized by unilateral training and/or electrical Stimulation.Objective: To examine the effect(s) of unilateral long-term (20 weeks) standardized resistance training with and without simultaneous Electro-Stimulation on leg muscle strength and overall functional mobility.Methods: A randomized controlled trial involving 36 persons with MS. At baseline (PRE) and after 10 (MID) and 20 (POST) weeks of standardized (ACSM) light to moderately intense unilateral leg resistance training (RESO, n = 11) only or resistance training with simultaneous Electro-Stimulation (RESE, n = 11, 100 Hz, biphasic symmetrical wave, 400 µs), maximal isometric strength of the knee extensors and flexors (45°, 90° knee angle) and dynamic (60–180°/s) knee-extensor strength was measured and compared with a control group (CON, n = 14).

Effects of long-term resistance training and simultaneous Electro-Stimulation on muscle strength and functional mobility in multiple sclerosis
Multiple Sclerosis Journal, 2011Co-Authors: Tom Broekmans, Geert Alders, Ine Hanssen, Machteld Roelants, Peter Feys, Piet Stinissen, Domien Gijbels, Bert O. EijndeAbstract:Background: Resistance training studies in multiple sclerosis (MS) often use short intervention periods. Furthermore, training efficiency could be optimized by unilateral training and/or electrical Stimulation. Objective: To examine the effect(s) of unilateral long-term (20 weeks) standardized resistance training with and without simultaneous Electro-Stimulation on leg muscle strength and overall functional mobility. Methods: A randomized controlled trial involving 36 persons with MS. At baseline (PRE) and after 10 (MID) and 20 (POST) weeks of standardized (ACSM) light to moderately intense unilateral leg resistance training (RESO, n = 11) only or resistance training with simultaneous Electro-Stimulation (RESE, n = 11, 100 Hz, biphasic symmetrical wave, 400 μs), maximal isometric strength of the knee extensors and flexors (45°, 90° knee angle) and dynamic (60-180°/s) knee-extensor strength was measured and compared with a control group (CON, n = 14). Functional mobility was evaluated using the Timed Get Up and Go, Timed 25 Foot Walk, Two-Minute Walk Test, Functional Reach and Rivermead Mobility Index. Results: Maximal isometric knee extensor (90°, MID: +10 ± 3%, POST: +10 ± 4%) in RESO and knee flexor (45°, POST: +7 ± 4%; 90°, POST: +9 ± 5%) in RESE strength increased (p < 0.05) compared with CON but RESO and RESE did not differ. Also, impaired legs responded positively to resistance training (unilateral leg strength analysis) and functional reaching increased significantly in RES O (+18%) compared with CON. Dynamic muscle strength and the remaining functional mobility tests did not change. Conclusion: Long-term light to moderately intense resistance training improves muscle strength in persons with MS but simultaneous Electro-Stimulation does not further improve training outcome. © The Author(s) 2010.

EMBC - Effect of saccades in tongue Electrotactile Stimulation for vision substitution applications
Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and, 2013Co-Authors: Abdessalem Chekhchoukh, Yohan Payan, Nicolas Vuillerme, Nicolas GladeAbstract:The visual substitution paradigm aims to facilitate the life of blind people. Generally one uses Electro-stimulating devices where Electrodes are arranged into arrays to stimulate the skin or the tongue mucosa to send signals of visual type to the subjects. When an Electro-Stimulation signal is applied continuously (e.g. when static visual scenes are displayed for a long period of time), the receptors of the affected region can get saturated and the patient may lose the displayed information. We propose here some mechanisms that ameliorate the quality of perception of the Electro-Stimulation information. The electrical signal is encoded as 2D scenes projected onto the tongue via a Tongue Display Unit, i.e. an Electro-tactile stimulator formed by a 12×12 matrix of Electrodes. We propose to apply stochastic saccades on this signal. Our assumption is that this eye-inspired mechanism should make the visual substitution more efficient (by improving the perception) because of the reduction of the tactile receptors saturation. The influence of saccades was evaluated by a series of experiments. Results revealed a benefit on the persistence of perception due to saccades. This work helps to prevent the saturation of receptors on the tongue. Therefore increasing the quality of vision by the way of the Electro-Stimulation. It allows new enhancement features to retinal prosthesis devices which suffer from the same phenomenon.

Influence of Sparkle and Saccades on Tongue Electro-Stimulation-Based Vision Substitution of 2D Vectors
Acta Biotheoretica, 2012Co-Authors: Abdessalem Chekhchoukh, Nicolas GladeAbstract:Vision substitution by Electro-Stimulation has been studied since the 60s beginning with P. Bach-y-Rita. Camera pictures or movies encoded in gray levels are displayed using an Electro-Stimulation display device on the surface of a body part, such as the skin or the tongue. Medical-technical devices have been developed on this principle to compensate for sensory-motor disabilities such as blindness or loss of balance, or to guide specific actions, such as surgery. However, the electrical signals of stationary or moving slowly moving objects, displayed on a Tongue display unit (TDU), are quickly lost due to saturation of receptors undergoing ElectroStimulation. We propose to add random saccades or sparkle to the displayed visual scene to increase the quality of pattern recognition by the subjects. In the present experimental trimodal study (normal vision, TDU vision substitution, or both), we show that the presence of a moderate sparkle level enhances the perception of the direction of lines drawn on a TDU and reduces the response time.

Vision substitution and moving objects tracking in 2 and 3 dimensions via vectorial Electro-Stimulation of the tongue
Conférence Internationale sur l'accessibilité et les systèmes de suppléance aux personnes en situations de handicaps, 2011Co-Authors: Abdessalem Chekhchoukh, Nicolas Vuillerme, Nicolas GladeAbstract:Vision substitution by Electro-Stimulation has been studied since the 60’s. Camera pictures or movies encoded in gray levels are dis- played via an Electro-Stimulation device at the surface of a body part, e.g. the skin or the tongue. Medico-technical devices are developed on this principle to take care of sensorimotor handicaps like blindness or equilibrium, or to guide precise acts like in surgery. We propose here to reduce the complexity of the displayed information to vectorial encoded 2D, but also 3D, scenes projected on the tongue via a Tongue Display Unit of 12×12 Electrodes. Such vectorial encoding presents the advan- tage to furnish to the subjects only useful informations so as to increase the quality of recognition of 2D or 3D scenes and to reduce their cog- nitive load, i.e. the latency of time-to-recognition of such scenes. In the present experimental trimodal (normal vision, TDU vision substitution, or both) study on healthy people we show that the subjects are able to perceive correctly the orientation of motionless sparkling lines and to follow the trajectory of moving objects into dynamic 2D or 3D scenes. These experiments also allowed us to show the influence of the vision modality: standard deviations on the answers, moving object tracking accuracy, and response times increased consequently in case of bimodal Stimulation.
