How a devastating stroke changed this N. Va. consultant's path
Welcome to Off the Beat, a weekly Q&A with a local business person doing something a little different. Have an idea or pitch that reflects some unusual business activity? Email mneibauer@bizjournals.com. Sameer Bhide of Vienna is a consultant by trade, stroke survivor and now, author. His book, "One Fine Day," details the brain hemorrhage he suffered in January 2017 and the excruciating recovery from it. Why did you write “One Fine Day?” Before my stroke in January 2017, my life was normal…

Sensors, Vol. 21, Pages 5130: Estimation of Stroke Volume Variance from Arterial Blood Pressure: Using a 1-D Convolutional Neural Network
Conclusions: We developed a new CNN deep-learning model to estimate SVV. Our CNN model seems to be a viable alternative when the necessary medical device is not available, thereby allowing a wider range of application and resulting in optimal patient management.

Sensors, Vol. 21, Pages 5162: Framework for Intelligent Swimming Analytics with Wearable Sensors for Stroke Classification
io Faria Intelligent approaches in sports using IoT devices to gather data, attempting to optimize athlete’s training and performance, are cutting edge research. Synergies between recent wearable hardware and wireless communication strategies, together with the advances in intelligent algorithms, which are able to perform online pattern recognition and classification with seamless results, are at the front line of high-performance sports coaching. In this work, an intelligent data analytics system for swimmer performance is proposed. The system includes (i) pre-processing of raw signals; (ii) feature representation o...

Five ‐Session Dual‐Transcranial Direct Current Stimulation With Task‐Specific Training Does Not Improve Gait and Lower Limb Performance Over Training Alone in Subacute Stroke: A Pilot Randomized Controlled Trial
ConclusionThe combined intervention showed no benefit over training alone in improving gait variables and lower-limb performance. However, some performances were saturated at some point, as moderate to high function participants were recruited in the present study. Future studies should consider recruiting participants with more varied motor impairment levels and may need to determine the optimal stimulation protocols and parameters to improve gait and lower-limb performance.

Sensors, Vol. 22, Pages 1374: Artificial Neural Network Detects Hip Muscle Forces as Determinant for Harmonic Walking in People after Stroke
ni Morone Many recent studies have highlighted that the harmony of physiological walking is based on a specific proportion between the durations of the phases of the gait cycle. When this proportion is close to the so-called golden ratio (about 1.618), the gait cycle assumes an autosimilar fractal structure. In stroke patients this harmony is altered, but it is unclear which factor is associated with the ratios between gait phases because these relationships are probably not linear. We used an artificial neural network to determine the weights associable to each factor for determining the ratio between gait phases and ...

Sensors, Vol. 22, Pages 2060: Hand Measurement System Based on Haptic and Vision Devices towards Post-Stroke Patients
ubrycki Diagnostics of a hand requires measurements of kinematics and joint limits. The standard tools for this purpose are manual devices such as goniometers which allow measuring only one joint simultaneously, making the diagnostics time-consuming. The paper presents a system for automatic measurement and computer presentation of essential parameters of a hand. Constructed software uses an integrated vision system, a haptic device for measurement, and has a web-based user interface. The system provides a simplified way to obtain hand parameters, such as hand size, wrist, and finger range of motions, using the homogen...

Sensors, Vol. 22, Pages 2273: Determinants of Different Aspects of Upper-Limb Activity after Stroke
We examined factors associated with different aspects of upper-limb (UL) activity in chronic stroke to better understand and improve UL activity in daily life. Three different aspects of UL activity were represented by four sensor measures: (1) contribution to activity according to activity ratio and magnitude ratio, (2) intensity of activity according to bilateral magnitude, and (3) variability of activity according to variation ratio. We combined data from a Belgian and Danish patient cohort (n = 126) and developed four models to determine associated factors for each sensor measure. Results from standard multiple regress...

Distribution of Nicotinamide Mononucleotide After Intravenous Injection in Normal and Ischemic Stroke Mice
CONCLUSION: Intravenous NMN distributes to various tissues after intravenous injection and is able to enter into brain to boost NAD levels and exhibits safety and therapeutic effect on acute ischemic stroke injury. High renal distribution of NMN indicates its importance in kidney.PMID:35593333 | DOI:10.2174/1389201023666220518113219

Sensors, Vol. 22, Pages 5066: Detection of a Stroke Volume Decrease by Machine-Learning Algorithms Based on Thoracic Bioimpedance in Experimental Hypovolaemia
Aarne Feldheiser Compensated shock and hypovolaemia are frequent conditions that remain clinically undetected and can quickly cause deterioration of perioperative and critically ill patients. Automated, accurate and non-invasive detection methods are needed to avoid such critical situations. In this experimental study, we aimed to create a prediction model for stroke volume index (SVI) decrease based on electrical cardiometry (EC) measurements. Transthoracic echo served as reference for SVI assessment (SVI-TTE). In 30 healthy male volunteers, central hypovolaemia was simulated using a lower body negative pressure (LBN...
