FlexiGuard: Modular biotelemetry system for military applications

Jakub Schlenker Vladimír Socha Pavel Smrčka Karel Hána Vladimir Begera

The article presents a FlexiGuard modular biotelemetric system for real-time monitoring of special military units. The main focus of the system is on automated monitoring of special forces via parallel monitoring of each member of the special team individually, witch includes collecting sets of physiologic (or environmental) parameters. The systems consists of a set of sensors (for monitoring temperature, heart rate, acceleration, humidity etc.) and modular sensing unit, which records the measured data and sends them to the visualization unit. The measured values (i.e. heart rate, surface temperature of the body and so on) are then visualized in the graphic user interface of the visualization unit. Testing of the functionality of the system took place in both laboratory and real environment. In the case of carrying out the measurements on 34 soldiers at series of 4 probands at the same time, the sensor networks worked without any loss of signal. During the data transfer to the visualization unit, a loss of approx 0.2% of packets occurred. The system thus can offer information to the commander, which may prove essential for the optimalization of operational strategies, taking the state of wellbeing of the team members into account.

System for Game-like Therapy in Balance Issues Using Audiovisual Feedback and Force Platform

Electronics (2022)

Markéta Janatová Jakub Pětioký Kristýna Hoidekrová Tomáš Veselý Karel Hána

Background: The aim of the work is to verify the usability of a stabilometric platform and audiovisual feedback in the group-based therapy of patients with vertebral algic syndrome, to analyze an immediate effect after a single therapeutic unit, and to analyze differences between male and female probands. Methods: The study included 189 patients (90 male, age 55 ± 12 and 89 female, age 52 ± 12). All patients received group balance therapy with a portable medical device, Homebalance MA. The intervention consisted of measurement of quiet stance and a reference training scene before and after 15 min of game-like balance training with audiovisual feedback. Results: A statistically significantly lower value of the body sway trajectory during quiet stance was detected in men than in women. After a single therapy session, there was a statistically significant improvement in quiet stance with visual feedback, and marginal statistically significant improvement in the time required to complete the reference training scene. Conclusions: Homebalance MA is a utilizable tool for group therapy. The use of group game-like balance training increases the availability of physiotherapeutic intervention for a larger number of patients, while maintaining the positive effect of the therapy.

Model of myoelectric arm with obstacle detection system using fuzzy logic

International Conference on Applied Electronics (2013)

Patrik Kutílek Pavel Smrčka Ján Hýbl

This paper presents a new system designed for application in upper extremity prosthesis. Artificial upper limb with our system is experimental robot arm controlled by EMG signals and signals from obstacle detection sensors. The multi-sensor system is based on ultrasonic sensors and motor load sensors for detecting the obstacles and loads applied to the actuators. The motor load sensors indicate physical contact with an object, and fuzzy expert system identifies the approximate magnitude and direction of an external contact force. The multi-sensor system can identify distance of obstacles and collisions in 3D space. The used robotic arm is a model of promising prosthetic arm and its control system and used methods were designed and verified by MatLab/Simulink.

Kinematic quantification of gait asymmetry in patients with peroneal nerve palsy based on bilateral cyclograms.

PubMed (2013)

Patrik Kutílek Slávka Vítečková Zdeněk Svoboda Pavel Smrčka

Nowadays, bipedal walking is undergoing extensive study. Several methods can be used in physiotherapeutic research for identifying defects in bipedal walking as a result of pathology of the musculoskeletal or nervous system. Our work focuses on studying asymmetry of walking based on synchronized bilateral knee-knee cyclograms. Participants presenting with peroneal nerve palsy and foot drop were included in the study. The bilateral cyclograms, also called angle-angle diagrams, were created to quantify gait asymmetry before and immediately after application of a brace. In order to quantify the asymmetry of human walking, we have described and tested the application of the method based on the inclination angle of the synchronized bilateral cyclograms. The symmetry index (SI) was used as a comparative method to evaluate the symmetry of bipedal walking. The method based on the orientation of the cyclograms can be used as an additional method for determining the gait asymmetry. The new technique has never been applied before to study the gait asymmetry in patients with peroneal nerve palsy or patients with leg brace.

A COMPARISON OF METHODS USING STRAIN GAUGES TO MONITOR PHYSIOLOGICAL MOVEMENTS ON A HOSPITAL BED

Acta Polytechnica (2014)

Vladimír Socha Patrik Kutílek Pavel Smrčka Ľuboš Socha

Two methods which are suitable to monitor the small movements of the patient in a horizontal position on the bed are compared. The methods use sensors based on strain gauge bridges configured to measure the torsion deformation and sensors based on strain gauge bridges configured to measure the bending deformation of two two-arm brackets. Both methods provide information about the patient's physiological movements. The methods were tested and compared in order to decide which methods may be most appropriate in clinical practice. The two methods have never been compared before, and the results can be used in development of the new methods of patient monitoring.

A Surveillance System for Enhancing the Safety of Rescue Teams

Communications - Scientific letters of the University of Zilina (2015)

Zdeněk Hon Pavel Smrčka Karel Hána J. Kašpar Jan Mužík

The article summarizes preliminary results of the research and development of a system focused on enhancing the safety of teams participating in the integrated rescue system managing extraordinary events or crisis situations (fire, mass disaster, release of harmful industrial substances), and on the support in the course of training. Individual partial technical solutions are mentioned, which should lead to providing automatized telemetric monitoring equipment in a more resistant form making it possible to recognize the nature and intensity of the motion, including the determination of the topical and total energy outputs, monitoring of environmental parameters (temperature, smoke, etc.) and back analysis of the intervention course or training in real time, and the monitoring of health-physiological parameters and signalling risk conditions (physical exhaustion, stress, overheating, etc.) under extreme measures.

[PP.16.13] HOME BLOOD PRESSURE TELEMONITORING OFFERS MORE RELIABLE VALUES AND INFORMATION ABOUT IRREGULAR HEARTBEAT EPISODES

Journal of Hypertension (2017)

Jan Mužík Jan Peleška Marek Doksanský D. Gillar J. Kašpar

Objective: BP values reported by the patient from home BP monitoring (HBPM) may not always be reliable due to intentional or unintentional transcription errors. However, direct HBP telemonitoring can eliminate such mistakes. The detection of asymptomatic atrial fibrillation (AF) (or irregular heartbeat rhythm – IHR) by new technologies including BP machines with AF detection algorithms has not yet been formally evaluated against an established method. Design and method: The presented telemedicine system transfers data directly, without any patient interaction, from a BP measuring device via a Bluetooth interface and sends them to a telemedicine server. Values can be sent either directly using an Intel Compute Stick mini-PC or indirectly via a mobile application that uses Apple HealthKit as an intermediate storage. Internally, IHR is treated as another measured variable and is transferred to the server. In the electronic logbook, measurements containing detected IHR are displayed with highlighted heart rate (HR) value and the IHR symbol. Results: Data are presented in the web logbook, which is based on the ESH standardised logbook transferred to Excel. The logbook automatically calculates the average systolic and diastolic BP (total, morning and evening) from several days. Thus, it offers a better titration of pharmacotherapy. Different colours indicate extremely high or low BP and HR levels with warnings for the patient to contact his/her physician. Results of a mean BP evaluation are also shown as well. A chart and table with a daytime BP profile automatically extracted from all values partially mimics ABPM. The patient's logbook is accessible to both the patient and the physician via a web application. It can also be generated as a pdf and sent to the physician by email, alternatively it can be printed. Using the latest HL7 FHIR, the measured values can be directly sent to a hospital information system.Conclusions: The presented HBPTM compared to the usual HBPM offers more reliable BP values, calculations of BP mean, a daytime BP profile and can help in timely detection of asymptomatic AF. It is suitable for a physician's everyday work without the need to share the data.

Using mobile technologies with psychiatric patients: Assessing the potential to reduce risk of developing diseases related to inactivity

Anna Holubová Jakub Schlenker Vladimír Socha Jan Mužík D. Gillar

Mental disorders, such as schizophrenia, are accompanied by increased morbidity and mortality rates, potentially reducing the lifespan of patients by up to 10 years. Premature deaths in schizophrenia sufferers are caused mainly by cardiovascular diseases and complications related to excessive weight gain and type 2 diabetes mellitus. Gaining weight is, furthermore, often a side effect of medicine prescribed for the treatment of schizophrenia. This is why treatment protocols are putting a greater emphasis on healthy lifestyle and exercise for patients, which may support both weight loss and suppress feelings of anxiety. It is, therefore, important for a doctor to monitor the exercise habits of their patients. This article focuses on telemonitoring of physical activity and other biological parameters in patients with mental disorders, such as schizophrenia, using the recent m-Health technology in the form of a Fitbit Flex activity tracker. The Soma web portal has been created to continuously monitor, visualize and analyse the data measured on patients within the scope of research activities.
