In this study, we investigated the feasibility of predicting the performance of a specific guidewire in terms of its ability to cover a lesion cap surface and apply force to the lesion for a given patient's vessel anatomy. The aim of this research was to provide information that could be used to plan occlusion crossings and peripheral revascularization procedures preoperatively in a way that reduces the risk of potential intraoperative complications and increases the likelihood of success. We used finite element (FE) analysis to simulate the interaction between the guidewire and a model of a tortuous vessel, and we used this simulation to predict the reachable workspace and deliverable forces of the device for various entry positions and angles. We then validated these predictions through experiments in which we advanced a guidewire through an identical vessel phantom using a robotic manipulator. Our findings suggest that it may be possible to predict the performance of a guidewire and forecast the likelihood of success or failure for a given vessel anatomy and lesion morphology, which could enable improved planning and device selection.

Objective: This study aimed to assess reachable workspace (RWS) in patients post-osteosynthesis of shoulder, elbow, or wrist fractures and explore correlations with self-reported function and kinesiophobia.
Design: An observational case-control study compared patients with fractures to a control group, utilizing questionnaires and 3D kinematic data.
Participants: The sample included 66 individuals who had undergone osteosynthesis: 21 with shoulder fractures, 10 with elbow fractures, and 22 with wrist fractures.

Article Synopsis
- FSHD is a genetic muscle disorder that can start in childhood, affecting about 20% of patients early on. Understanding its progression and outcomes is important for care and research.
- A study followed 20 childhood-onset FSHD patients over 5 years, assessing muscle function and disease severity with various tests. Most participants did not notice changes in their condition, despite measurable progression.
- Results showed variable disease progression, with improvements in quality of life and decreased fatigue. The study emphasizes the need for more sensitive outcome measures and larger international studies in future pediatric research.
Structural Parameter Optimization of a Tomato Robotic Harvesting Arm: Considering Collision-Free Operation Requirements.

The current harvesting arms used in harvesting robots are developed based on standard products. Due to design constraints, they are unable to effectively avoid obstacles while harvesting tomatoes in tight spaces. To enhance the robot's capability in obstacle-avoidance picking of tomato bunches with various postures, this study proposes a geometric parameter optimization method for a 7 degree of freedom (DOF) robotic arm.

Optimal upper extremity motor control and range of motion are necessary to achieve even the basic activities of daily living (ADL) function. Stroke, with resulting hemiparesis, can significantly and negatively impact an individual's ADL function. Functional Independence Measure (FIM) self-care score can provide an assessment of what aspects and to what degree ADL functions are impaired.

Introduction: Soft robotics play an increasing role in the development of exosuits that assist, and in some cases enhance human motion. While most existing efforts have focused on the adult population, devices targeting infants are on the rise. This work investigated how different configurations pertaining to fabric-based pneumatic shoulder and elbow actuator embedding on the passive substrate of an exosuit for pediatric upper extremity motion assistance can affect key performance metrics.
