An Alternative Myoelectric Pattern Recognition Approach for the Control of Hand Prostheses: A Case Study of Use in Daily Life by a dysmelia subject
The functionality of upper limb prostheses can be improved by intuitive control strategies that use bioelectric signals measured at the stump level. One such strategy is the decoding of motor volition via myoelectric pattern recognition (MPR), which has shown promising results in controlled environments and more recently in clinical practice. Moreover, not much has been reported about daily life implementation and real-time accuracy of these decoding algorithms. This study introduces an alternative approach in which MPR allows intuitive control of four different grips and open/close in a multifunctional prosthetic hand.
Physiological Recording in the MRI Environment (PRiME): MRI-Compatible Hemodynamic Recording System
Hemodynamic recording during interventional cardiovascular procedures is essential for procedural guidance, monitoring patient status, and collection of diagnostic information. Recent advances have made interventions guided by magnetic resonance imaging (MRI) possible and attractive in certain clinical scenarios. However, in the MRI environment, electromagnetic interference (EMI) can cause severe distortions and artifacts in acquired hemodynamic waveforms. The primary aim of this paper was to develop and validate a system to minimize EMI on electrocardiogram (ECG) and invasive blood pressure (IBP) signals.
Mastication Evaluation with Unsupervised Learning: Using an Inertial Sensor-Based System
There is a direct relationship between the prevalence of musculoskeletal disorders of the temporomandibular joint and orofacial disorders. A well-elaborated analysis of the jaw movements provides relevant information for healthcare professionals to conclude their diagnosis. Different approaches have been explored to track jaw movements such that the mastication analysis is getting less subjective; However, all methods are still highly subjective, and the quality of the assessments depends much on the experience of the health professional.
Evaluation of Ventilation-Induced Lung Inflammation through Multiscale Simulations
Ventilation-induced lung injury is a common problem faced by patients with respiratory problems who require mechanical ventilation (MV). This injury may lead to a greater chance of developing or exacerbating the acute respiratory distress syndrome which further complicates the therapeutic use of MV. The chain of events begins with the MV initiating an immune response that leads to inflammation induced tissue material alteration (stiffening) and eventually the loss of lung resistance.
Search for Editor-in-Chief: IEEE Journal of Translational Engineering in Health and Medicine
IEEE Engineering in Medicine and Biology Society (EMBS) is undertaking a search for Editor-In-Chief for the IEEE Journal of Translational Engineering in Health and Medicine (J-TEHM). We will begin reviewing applications by March 15, 2018.
Detection of Essential Tremor at the S-Band
Essential tremor (ET) is a neurological disorder characterized by rhythmic, involuntary shaking of a part or parts of the body. The most common tremor is seen in the hands/arms and fingers. This paper presents an evaluation of ETs monitoring based on finger-to-nose test measurement as captured by small wireless devices working in shortwave or S-band frequency range. The acquired signals in terms of amplitude and phase information are used to detect a tremor in the hands.
