TL;DR: There is a gap in the market for a new high fidelity hip replacement and resurfacing training simulator, and there is increasing use of patient-specific virtual models which reduce the learning curve, for orthopaedic surgery simulators in general.

TL;DR: A user centered review is presented on requirements for orthosis actuators; the electric, hydraulic, and pneumatic actuators currently used in orthoses and their advantages and limitations; the potential of new actuator technologies, including smart materials, to actuate orthoses; and the future of Orthosis actuator research.

TL;DR: It is suggested that an IMU is a valid tool to measure dynamic pelvic angles during various activities of daily life which could be applied to monitor rehabilitation in a wide variety of musculoskeletal disorders.

TL;DR: This work proposes to implement an adaptive neuro fuzzy inference strategy (ANFIS) to predict the in-socket residual limb temperature and results indicate that both the modeling techniques have comparable performance metrics and can be efficiently used for non-invasive temperature monitoring.

TL;DR: For the cases examined, the effect of stress shielding on the periprosthetic bone seems to be more significantly influenced by the implant material than by the implants geometry.

TL;DR: This work uses a particle-based mesoscopic hydrodynamic simulation approach to investigate the margination of different carriers for a wide range of hematocrits and flow rates, and shows that margination strongly depends on the thickness of the available free space close to the wall, the so-called red blood cell-free layer (RBC-FL), in comparison to the carrier size.

TL;DR: The results of this study suggest that the Kinect for Windows v2 has the capacity to measure selected spatiotemporal gait parameters for healthy adults.

TL;DR: This paper aims to provide a systematic overview and evaluation of existing bilateral upper-limb rehabilitation devices and robots based on their mechanisms and clinical-outcomes to explore the actual value of these robots and devices.

TL;DR: The domain of admissible stimulation intensities that results from the nonlinearities in patients' stimulation intensity tolerance is characterized and a nonlinear controller output mapping is applied to compensate most of the cross-couplings between the FES intensities and the foot motion.

TL;DR: Preliminary amputee test results suggest strong potential of the developed sensor system for exploitation as an assistive technology to facilitate socket design, socket fit and effective monitoring of lower limb residuum health.

TL;DR: Evidence is provided that the external portable aDBS system prototype designed for clinical testing in freely-moving PD patients with externalized DBS electrodes can track levodopa and DBS-induced LFP spectral power changes among different patient's clinical states.

TL;DR: It is shown that predictions of an individual's age, height, and sex can be improved by using 3-D shape and cortical thickness when compared with traditional morphometric measurements, and that femoral cortex geometry can be predicted from anthropological data combined with femoral measurements with less than 2.3 mm root mean square error.

TL;DR: This paper presents a review of the state of the art of current hybrid robotic solutions for upper limb rehabilitation after stroke, selected through a search using web databases: IEEE-Xplore, Scopus and PubMed.

TL;DR: It has been noticed that the deformability of RBCs induces cells aggregation during flow in microcapillaries, allowing the formation of clusters of cells, which can be used for the analysis of pathological RBC's collective behavior, for which reliable quantitative methods are still lacking.

TL;DR: Multiple-Network Poroelastic Theory (MPET) is used to develop a novel spatio-temporal model of fluid regulation and tissue displacement within the various scales of the cerebral environment to investigate the role of endoscopic fourth ventriculostomy in alleviating oedema formation.

TL;DR: The purpose of this review paper is to summarize the current knowledge on cell-scale mechanically-inflicted deformation-damage, which is at the frontier of cell mechanobiology and biomechanics science, specifically in the context of chronic wounds.

TL;DR: A feasibility study in which healthy users were able to use a non-invasive Motor Imagery-based brain computer interface (BCI) to achieve linear control of an upper-limb functional electrical stimulation (FES) controlled neuro-prosthesis.

TL;DR: In this paper, the influence of process parameters (rotational speed, feed rate, drill diameter and vibrational amplitude) on change in the temperature was studied using design of experiment technique i.e., response surface methodology (RSM) and data analysis was carried out using ANOVA.

TL;DR: There exists a need to carry out a more comprehensive validation study for the SWF loading mode to identify which combination of MMMs and E-ρ relationship leads to the best match for whole bone and local mechanical response.

TL;DR: Fiber-reinforced constitutive modeling that takes into account the collagen fiber defect inherent to the aneurysmal ascending aorta is paramount for accurate finite element predictions and ultimately for biomechanical-based indicators to reliably distinguish the more from the less 'malignant' ATAAs.

TL;DR: There appears to be an optimal fixation configuration for a given angle of obliquity and gap size, which could enhance callus formation in presence of a large gap but could lead to excessive callus strain and interstitial fluid flow when a small transverse fracture gap is present.

TL;DR: The results suggest that the subject-specific MSK MBD modelling framework for TKA using FDK has potential as a powerful tool for investigating the functional outcomes of knee implants.

TL;DR: The system reported in this paper advances the state-of-the-art by integrating an FES electrode array on the forearm to assist complex hand and wrist gestures, and employing an interactive touch table to present motivating virtual reality (VR) tasks.

TL;DR: It is demonstrated that with various possible assumptions of lumbar spine rhythm and intra-abdominal pressure, variation in predicted loads and muscles forces increase with larger flexion, so it is essential to adapt these model parameters for accurate prediction of spinal loads and trunk muscle forces.

TL;DR: An inertial measurement unit based algorithm was developed and validated to monitor wheel kinematics and the type of wheelchair propulsion (self- or attendant-) within a "real-world" situation.

TL;DR: The transverse and sigmoid colons were the major determinant in tortuosity and morphometrics between body orientations and may potentially help to facilitate colonoscopy techniques, accuracy of polyp spatial distribution detection, and design of novel endoscopic devices.

TL;DR: This work compared the performance of six different fatigue detection algorithms quantifying muscle fatigue based on electromyographic signals obtained by an experiment from upper arm contractions at three different load levels from twelve volunteers.

TL;DR: An optimized drilling method has been found which might also enable drilling in more delicate procedures such as that performed during minimally invasive robotic cochlear implantation.

TL;DR: It is suggested that correct positioning the component to avoid edge loading that may occur during daily activities is important for MoP THR in clinical practice.

TL;DR: It is demonstrated that peri-implant bone damage already occurs during screw insertion, and this should be taken into consideration to further improve primary implant stability, especially in low quality osteoporotic bone.
