Transcranial magnetic stimulation is a noninvasive brain stimulation technique. It is based on current induction in the brain with a stimulation coil emitting a strong varying magnetic field. Its development is currently limited by the lack of accuracy and repeatability of manual coil positioning. A dedicated robotic system is proposed in this paper. Contrary to previous approaches in the field, a custom design is introduced to maximize the safety of the subject. Furthermore, the control of the force applied by the coil on the subject's head is implemented. The architecture is original and its experimental evaluation demonstrates its interest: the compensation of the head motion is combined with the force control to ensure accuracy and safety during the stimulation.

Background: This study aims to investigate the effects of a multimodal program using augmented reality on the functional fitness and physical activity of older adults living in the community.
Method: Seventy-eight older adults living in the community participated in this study. Participants were divided into three groups: a control group that maintained their usual activities, and two experimental groups, one with multimodal training (EG1) and the other with multimodal training combined with augmented reality (EG2).

Paragangliomas, a type of extra-adrenal tumour, albeit rare, are dangerous due to their high metastatic potential and risk of hypertensive crisis from massive catecholamine release. It typically presents with sympathetic overdrive symptoms such as diaphoresis, headache, and palpitation, accompanied by substantially high plasma metanephrines level and mass on contrasted computed tomography abdomen and pelvis, whilst some are found incidentally. In this report, we discuss a case of an extra-adrenal lesion located near susceptible major structures with extensive vascularisation, in a patient with near-death experience.

Background: Traditional freehand puncture relies on non-real-time computed tomography (CT) images, which significantly affects the accuracy of puncturing targets in the lower lung lobes with respiratory motion. This study aims to assess the safety and feasibility of a teleoperated robotic system and low-dose CT for the accurate real-time puncture of targets in the lungs of live pigs during breathing under fluoroscopic guidance.
Methods: Two puncture methods were analyzed: freehand and robot-assisted.

Objective: To investigate the feasibility of remotely providing routine ultrasound (US) examinations to patients using a fifth-generation-based robot-assisted tele-ultrasonography (RATU) system in a real-world setting.
Methods: Between September 2020 and May 2021, we conducted a prospective and large-scale study using the RATU system to provide US examinations for patients on a limited-source island locate. An on-site radiologist on the island performed US examinations, which served as the reference diagnosis.

Mass production of biomedical microrobots demands expensive and complex preparation techniques and versatile biocompatible materials. Learning from natural bacteria flagella, the study demonstrates a magnetic polymer multilayer cylindrical microrobot that bestows the controllable propulsion upon an external rotating magnetic field with uniform intensity. The magnetic microrobots are constructed by template-assisted layer-by-layer technique and subsequent functionalization of magnetic particles onto the large opening of the microrobots.
