Abstract
Introduction: The mechanical properties of skeletal muscle are indicative of its capacity to perform physical work, state of disease, or risk of injury. Ultrasound shear wave elastography conducts a quantitative analysis of a tissue's shear stiffness, but current implementations only provide two-dimensional measurements with limited spatial extent. We propose and assess a framework to overcome this inherent limitation by acquiring numerous and contiguous measurements while tracking the probe position to create a volumetric scan of the muscle. This volume reconstruction is then mapped into a parameterized representation in reference to geometric and anatomical properties of the muscle. Such an approach allows to quantify regional differences in muscle stiffness to be identified across the entire muscle volume assessed, which could be linked to functional implications. Methods: We performed shear wave elastography measurements on the vastus lateralis (VL) and the biceps femoris long head (BFlh) muscle of 16 healthy volunteers. We assessed test-retest reliability, explored the potential of the proposed framework in aggregating measurements of multiple subjects, and studied the acute effects of muscular contraction on the regional shear wave velocity post-measured at rest. Results: The proposed approach yielded moderate to good reliability (ICC between 0.578 and 0.801). Aggregation of multiple subject measurements revealed considerable but consistent regional variations in shear wave velocity. As a result of muscle contraction, the shear wave velocity was elevated in various regions of the muscle; showing pre-to-post regional differences for the radial assessement of VL and longitudinally for BFlh. Post-contraction shear wave velocity was associated with maximum eccentric hamstring strength produced during six Nordic hamstring exercise repetitions. Discussion and Conclusion: The presented approach provides reliable, spatially resolved representations of skeletal muscle shear wave velocity and is capable of detecting changes in three-dimensional shear wave velocity patterns, such as those induced by muscle contraction. The observed systematic inter-subject variations in shear wave velocity throughout skeletal muscle additionally underline the necessity of accurate spatial referencing of measurements. Short high-effort exercise bouts increase muscle shear wave velocity. Further studies should investigate the potential of shear wave elastography in predicting the muscle's capacity to perform work.

Abstract
BACKGROUND The chronic pelvic pain syndrome (CPPS) can be associated with physiotherapeutic findings. An interprofessional approach is recommended for patients with CPPS; however, no standardized physiotherapeutic assessment and documentation instrument for specific physiotherapeutic assessments exist, which is not only the foundation for physiotherapy but also for interprofessional communication. OBJECTIVE The aim was the development of a physiotherapeutic assessment instrument for patients with CPPS and therefore, to create a tool for clinical use, research and interprofessional communication. MATERIAL AND METHODS Based on an explorative literature search and an expert consensus, the first version of the instrument was developed as part of a specialized outpatient clinic. This version was applied clinically for 13 months, edited and finalized after another expert consensus. RESULTS The developed instrument Physical Therapy Assessment for Chronic Pelvic Pain Syndrome (PTA-CPPS) lists external and internal groups of muscles for a systematic assessment of myofascial findings. Functional capacity, breathing movements as well as scars and regions of pain are recorded. A manual for the assessment protocol was developed as accompanying material. CONCLUSION The developed instrument provides for the first time a physiotherapeutic assessment tool for patients with CPPS for interprofessional clinical and scientific use.

Abstract
Integration of haptics in Serious Games (SGs) remains limited compared to vision and audio. Many works seem to limit haptic interactions to the mimicking of real life feelings. Here, we address this by investigating the use of haptics to promote learning outcomes in serious games. By analyzing how we learn, we proposed a model that identifies three learning outcomes: (1) engage the user with the content of the game, (2) develop technical skills, and (3) develop cognitive skills. For each learning skill, we show how haptic interactions may be exploited. We also show that the proposed model may be used to describe and to evaluate existing methods. It may also help in the designing of new methods that take advantage of haptics to promote learning outcomes.
