Thus, continuous BP monitoring can facilitate early diagnosis and treatment of cardiovascular diseases. Since there is a lack of convenient methods for continuous BP monitoring, morphological analysis of an optical photoplethysmogram (PPG) signal is considered as an alternative.OBJECTIVE: Although PPG can be acquired from different body locations, it is unclear which is the most suitable for obtaining BP-related parameters. Hence, the aim of this study is to investigate the influence of the signal acquisition location on morphological PPG parameters.METHODS: PPG parameters from different body locations, i.e., finger, ear and neck, were assessed for 48 healthy participants performing 2 cold water tests. Changes in parameters between cold water and rest phases were checked for significance.RESULTS: Five out of seven parameters for the finger PPG changed significantly between all adjacent phases, whereas only sporadic changes were observed in the parameters for the ear and neck PPGs. However, all parameters except one showed significant changes at least once between cold water and rest phases.CONCLUTIONS: PPG signals acquired from the finger are the most suitable for assessing parameters potentially associated with changes in BP.","PeriodicalId":111164,"journal":{"name":"2021 International Conference BIOMDLORE","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115397939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anterior cruciate ligament (ACL) and meniscus injuries often require surgical treatment to return to high-level sports. ACL tears after reconstruction surgery carry a high recurrence rate. Balance training plays an important role in injury prevention programmes and is important to improve lower extremity function and decrease the risk of recurring knee injury. The research aim is to evaluate the effect of physiotherapy for an elite female handball player’s body balance and pain intensity after anterior cruciate ligament reconstruction and medial meniscus fixation. Body balance was evaluated with the Posturomed platform with two-dimensional measurement by MicroSwing software. Pain intensity was measured using the Visual Analogue Scale (VAS). A physiotherapy programme with an unstable oscillatory platform was developed and used to train the athlete’s body balance. Posturomed platform oscillations decreased from 34.1 cm to 16 cm in the frontal plane on the left leg and from 46 cm to 24.4 cm on the right leg; in the sagittal plane the platform distance changed from 273 cm to 256 cm on the left leg and 207 cm to 211 cm on the right leg. The average platform disturbance in the frontal plane was 22.73 ± 6.75 cm on the left leg and 31.21 ± 9.37 cm on the right; the average disturbance path in the sagittal plane was 254.5 ± 61.48 cm on the left leg and 223 ± 37.56 cm on the right leg. Balance stability increased from 55% (right leg) and 65% (left leg) to 89% (right leg) and 88% (left leg). During 6 weeks of intervention the pain intensity score changed from 7 to 3 (VAS). The six-week physiotherapy programme with an unstable oscillatory platform (Posturomed) improved body balance and decreased the pain intensity.","PeriodicalId":111164,"journal":{"name":"2021 International Conference BIOMDLORE","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123315981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Performed calculations enabled the identification of time intervals between successive trend changes in relation to the COP displacements.RESULTS: Test results revealed that, when standing, the most frequently appearing time intervals between successive trend changes were restricted within the range of 0.1 s. to 0.5 s.CONCLUSIONS: The above-presented trend was observed both in relation to the measurements conducted in the real environment and those performed in the oscillating virtual environment. The foregoing could indicate that the changes are characteristic and indispensable for the proper maintaining of balance by humans.","PeriodicalId":111164,"journal":{"name":"2021 International Conference BIOMDLORE","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122474841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following the data preprocessing stage, 16 patients with 14 features were selected. The cross-validation method with k = 4 was used to obtain the results of 3 classifiers trained using all the features. Moreover, the classification process was also applied to the most important features, selected according to a committee composed of feature importance algorithms.RESULTS: The results showed that the best outcomes were obtained using the logistic regression classifier, with the features selected by the attribute importance committee.CONCLUSIONS: It is not possible to use the system developed as a diagnostic tool at this point, due to the small amount of data. However, the results were good in terms of classification. Furthermore, the approach of using a committee to select the most important clinical features improved the results.

Ensuring safe and intuitive human robot interaction (HRI) is becoming a growing need, especially for pedestrians with mobility aids such as wheelchairs. The dynamics of wheelchair users differ from those of foot pedestrians, so accurate characterization of a wheelchair’s location and orientation for state estimation is crucial. The 2D laser scanner is a well-suited sensor for accurate distance measurements with fast computation speeds, but the sparsity of its data is often a hindrance to effective object detection. Despite so, 2D range data from laser scanners is found to be effective in the detection and orientation estimation of wheelchairs, even in cluttered environments. The range data from the scanner is pre-processed by segmenting out objects using density-based clustering. A two-step classification algorithm first identifies wheelchair candidates from segmented objects with the random forest classifier, then estimates the wheelchair’s orientation as one of six classes with a neural network. The models achieve 98% true positive rate for detection and 86% for orientation classification. The outcomes of this research can inform future works in building a real time wheelchair detection and state estimation for mobile robots.","PeriodicalId":111164,"journal":{"name":"2021 International Conference BIOMDLORE","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114762780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, pain is evaluated with subjective methods only, such as pain questionnaires. It may lead to erroneous evaluation of pain level. For this reason, there is a need for objective pain evaluation. The aim of this study is to test different neural network architectures and different types of inputs derived from finger plethysmography to evaluate which type of network and input type is most suitable for objective pain detection. Photoplethysmogram signals were filtered, segmented into heartbeat pulses, and normalized in amplitude and duration. The fifty-three signal intensity and fifteen time-domain features were extracted from the pre-processed photoplethysmogram signal. Three different neural network architectures were employed with ten different types of input. Results showed that feature-based models performed better than signal-based models. All three neural networks architectures achieved a mean accuracy of 0.85 for feature-based models and 0.76 for signal-based models. Multi-layer perception neural network with 12-heartbeats averaged showed the best performance with an accuracy of 0.92. Feature-based approach and multi-layer perception neural network showed the highest accuracy, specificity, and sensitivity for pain recognition.
