Visualization of biomechanical model parameters by adapting methods from game development

In biosignal processing, the importance of modeling and simulation to assist the development of methods, algorithms and systems is increasing. However, models and simulation environments may also be used in the later application, e.g. to enable physicians, therapists and nurses to provide assistance in treatment. Most of the time, however, the difficulty is to implement and apply the rather complex model data or to evaluate the output of the model. For this purpose, the paper presents a method that intelligibly prepares the input data of a biomechanical model for the end user using a game development environmen

ersonal smart travel agent for empowering persons with disabilities using public transport

Today's public transport is not easy to use by people having mental problems or those who are disabled. Traffic planning today is powered by online time tables calculating the optimal way to use public transport in terms of time and costs. Therefore usually a graph representing the public transport network is set up and algorithms taken from graph theory or operations research are used to find optimal routes. This is not suitable for a group of travellers having constraints in using vehicles, vehicle types or particular stations for health reasons. On the other hand, since most of those people are not able to drive a car on their own, making public transport available and moreover easily usable enable these people to improve their mobility and their quality of life in general. This paper shows an approach developed within the mobile project funded by The German Federal Ministry of economy and energy that allows supporting this group of users during a travel using public transport and undertaking personal constraints in route planning. This allows getting personalized advice during travel and while travel planning. This is implemented by generation of a second graph representing the public transport network not in dimension of time and costs but in preferences and dislike of a given traveller. The second graph is an overlay to the standard graph to get a personalized graph that allows finding a suitable route respecting the constraints of the user

Evaluation of the predictive value of the body-mass-index choosing perforator flaps from different donor sites

Abstract Background Free flap design must fulfill different criteria to ensure functional and aesthetic reconstruction of different types of defects in different body areas. A four-dimensional planning concept was used including flap length, width, thickness and tissue composition. This study evaluates if body-mass-index (BMI) has a predictive value for flap design. Methods A prospective study including hospitalized patients in the Department of Plastic, Aesthetic, Hand and Reconstructive Surgery was conducted. Not taking into account the reason for admission, the patients were examined based on age, weight, height, BMI and sex. The areas of a potential harvest of free fasciocutaneous and perforator flaps were measured using ultrasound examination to determine the thickness of the subcutaneous layers and prove blood perfusion. Results Over the period of four months, a total of 101 patients (36 females and 65 males) were included in this study and gave written consent. No statistical significance regarding the demographic data such as age, sex and BMI could be identified. An average to high correlation between free flap thickness and BMI was shown for the thoracodorsal artery perforator (TDAP), anterior lateral thigh (ALT) and deep inferior epigastric perforator (DIEP) flap in both, male and female patients. Free flaps of distal body parts such as the interosseous posterior flap, showed a lower correlation. No correlation using the Pearson coefficient could be found for age and volume. Conclusion Our study demonstrated that the BMI is a predictive indicator that can be used in the preoperative planning of reconstructions using free flaps. Depending on the defect location, the BMI can be considered to predict the thickness of the free flap and may influence the surgeon’s choice. On the other hand, a lower correlation between BMI and flap thickness encourages the use of standard flaps if more volume is desired, as the DIEP flap might be sufficient even in normal-weight women. Flaps of distal body parts, such as the forearm or lower leg, are not prone to such predictions and require other selection criteria

An HMM-based averaging approach for creating mean motion data from a full-body Motion Capture system to support the development of a biomechanical model

Motion capture systems or MoCap systems are used for game development and in the field of sports for the assessment and digitalization of human movement. Furthermore, MoCap systems are also used in the medical and therapeutic field for the analysis of human movement patterns. As examples gait analysis or examination of the musculoskeletal system and its function should be mentioned. Most application relate to a specific person and their movement or to the comparison of movements of different people. Within the scope of this paper an averaged motion sequence is supposed to be generated from MoCap data in order to be able to use it in the field of biomechanical modeling and simulation. For the averaging of individual movement sequences of different persons a Hidden Markov Model (HMM) based approach is presented
