Review and Development of Tetraplegic-Musculoskeletal FES-Elbow Joint Extension Control Strategies

The application of FES as a therapeutic and rehabilitation functionality is globally used especially for paralyzed person induced by SCI. The potential of this research is FES induced movement control on a significantly challenging area due to complexity and non-linearity of tetraplegic musculoskeletal system. The challenge mainly arises within FES application based on a crucial issue, in the control of musculoskeletal upper limb motor function by the artificial activation of paralyzed muscles, due to the various characteristics and parameters of the underlying physiological/biomechanical system. This research pilot study attempts to propose model theoretical framework/control strategies with computer validation simulations studies.

Preliminary approach of FES-cycling framework model development for spinal cord injury application: Part 1

Since 1960s, functional electrical stimulation (FES) applications has been used to improves, recover and restore several functions of paralyzed muscles due to spinal cord injury (SCI), stroke and any level of injury related to spinal. FES induced movement control is a significantly challenging area due to complexity and nonlinearity of musculoskeletal system which is the complexity control of muscle motor function model by the artificial activation of paralyzed muscles. Lots of research interest in lower-limb model especially for paraplegia either by exo-skeleton, gaiting exercise, robotics assistive device, wheel-chair, cycling, rowing and etc. Thus, in part one (1) of this paper discussed surface issues of several relations between software and hardware development via FES-Cycling framework model. Simple and efficient approach by using model-based design for experimental process and data gathering. The computer-based closed-loop FES-ScienceMode Hasomed-GmbH system uses MATLAB/Simulink, Software Development Kit 7.1 and RealTime Windows Target under Windows 7 for online data acquisition via microcontroller based, controlling and processing. Proposed optimization fuzzy control-strategy about FES-Cycling induced performance simulation studies against muscle fatigue and external disturbances with customized musculoskeletal mechanism lower limb model for cycling applied and majorly about result and discussions will be highlight in part two (2) for upcoming publications.

Lower body segmental dynamics control using eye blinking activity

Brain computer interface based functional electrical stimulation is a comparatively newer technique which is being used for rehabilitative and assistive technologies these days. This process needs precise calculations of relative factors and repetitive testing of those factors to provide approximate efficiency and stability. It is required to perform modelling and simulation of such systems in order to decrease number of experiments in humans. This study presents a modelling and simulation technique for lower limbs that utilized Neurosky Mindwave Mobile as a controlling device. LabVIEW has been used to connect the interface with the SolidWorks model. Blinking activity of a person is detected using Neurosky device and is translated to control the programmed movements in SolidWorks. This work is the early stage of the integration of brain-computer interface with other devices. In future work, the integration of these device and Functional Electrical Stimulator will be investigated.

Positioning of EEG electrodes for BCI-FES control system development of knee joint movement for paraplegic

Functional Electrical Stimulation (FES) is a promising method to restore mobility to individuals paralyzed due to spinal cord injury (SCI). This method will provide the electrical pulse to the surface electrodes which are attached to paralyze part such as arm or leg and will make this part constructs because of the pulse given and can achieve the desired movement later. Depend on only FES for a rehabilitation method to SCI patient is not a very effective way. The combination between FES and Brain Computer Interface (BCI) may prove useful and effective way in SCI rehabilitation. BCI is a technology that detects a patients intention. The main target of BCI is to create an alternative way for SCI patients between brain and others partfrom their body. This BCI will record the signal from the brain and then will transfer it to paralyze part which wants to control it. There are many methods to obtain the brain signals in BCI such as electroencephalographic (EEG) measurement technique or brain mapping technique. The EEG measurement technique is mostly used in medical rehabilitation and this technique is using EEG scalp and electrodes. The position of EEG electrodes should be correctly placed according to the appropriate movement. This paper will be discussed on the positioning of EEG electrodes for BCI-FES control system development of knee joint movement for paraplegics.

Level of Satisfaction for Occupational Safety and Health Training Activities: A Broad Spectrum Industrial Survey

The main objective of this research article is to identify the satisfaction level for occupational safety and health training activities among oil and gas drilling crew and staff. In this study, data has been gathered from reputed online oil and gas health and safety social and professional platforms through e-survey questionnaire. Similarly, for data analysis descriptive (Percentage %) and graphical statistical approach has been adopted for the interpretations of research findings by using SPSS 22.0 software. According to the overall findings of this paper, there is a sheer need of effective and sufficient training strategies for safety and health training activities at oil and gas extraction industries. As per respondents, there are also limited open source resources available by oil and gas companies for safety and health awareness and personal protection. Likewise, findings also indicated that, most of the participants of this online survey have reported about the communication gap between administration and drilling workforce for safety and health related issues and discussions which is one of the major causes of accidents and unexpected hazards at drilling sites.
