Background Each year, five million people are left disabled after stroke. Upper -extremity (UE) dysfunction is a leading problem. Neuroplasticity can be enhanced by non-invasive brain stimulation (NIBS) but evidence from large, randomized multicenter trial ...

Fluidic actuation enables movement in a wide range of mechanical systems, from simple laboratory devices to more complex industrial machinery. Fluids are used to generate motion of mechanical pieces. The term "fluids" encompasses two types of technologies: ...

This article proposes a swirling actuator that uses the electromagnetic radial force and mechanical gears to generate rotational torque. The proposed actuator generates a rotating radial force between an inner stator and a swirler. The gears on the swirler ...

We propose a novel machine learning (ML)-driven methodology to estimate biomechanical variables of interest traditionally obtained from upper-extremity musculoskeletal (MSK) modeling. MSK models facilitate personalized modeling, perform "what-if" analyses, ...

Context Long-term adherence to physical activity (PA) interventions is challenging. The Lifestyle-integrated Functional Exercise programmes were adapted Lifestyle-integrated Functional Exercise (aLiFE) to include more challenging activities and a behaviour ...

Objectives (i) to create a shortened version of the Action Research Arm Test scale, (ii) to investigate its psychometric properties compared to the original scale and (iii) to externally validate it within an independent cohort. Design Prospective longitud ...

Objective: To investigate (i) typical protocols used in research on biomechanical response to running-induced fatigue, (ii) the effect of sport-induced acute fatigue on the biomechanics of running and functional tests, and (iii) the consistency of analyzed ...

A flow directed device adapted to be guided by a fuid, such as blood, flow within a tubular structure such as a blood vessel is disclosed, said device comprising a proximal end (100), a distal end (101) and an elongated body (102) in between defining a lon ...

The invention provides for a steerable guidewire for insertion into a body cavity, characterized in that it comprises an elongated body (101) defining a longitudinally-arranged lumen (200) comprising i) a proximal end portion (100) and ii) a distal end por ...

The invention relates to a hand exoskeleton device having a modular nature. The device is designed to be wearable, portable and light in weight, and comprises from one to ten modules each having an actuating mechanism such as a linear actuator coupled with ...

A steerable device for use as e.g. a guidewire for insertion into a subject's body is disclosed. The device features a single side deflection of a bendable portion located at its distal end by application of a longitudinally-directed force either on an inn ...

A steerable catheter (10) comprises portions (100, 105) of different stiffness, having a proximal end (11), a distal end, a lumen extending there between, at least one magnet (20) at the proximal end (11), at least a magnetic field to influence the proxima ...

Stroke is one of the main causes of long-term disability worldwide, placing a large burden on individuals and society. Rehabilitation after stroke consists of an iterative process involving assessments and specialized training, aspects often constrained by ...

An implantable device for intrafascicular stimulation and/or sensing of a peripheral nerve, including a blocking element adapted for wrapping a nerve, comprising an access point and an exit point, and an electrode adapted to traverse the blocking element v ...

A connector for providing both a fluidic and electrical connection is disclosed, said connector having a proximal end, a distal end and an elongated body in between, characterized in that the elongated body has an inner cavity spanning throughout its lengt ...

Primary somatosensory cortex (S1) processes somatosensory information and is composed of multiple subregions. In particular, tactile information from the skin is encoded in three subregions, namely Brodmann areas (BAs) 3b, 1 and 2, with each area represent ...

The invention provides for a device (100) for use in electrical nerve modulation in a subject, characterized in that it comprises a rotational and linear actuator (110); a tubular element (101) having a proximal end connected to the actuator (110) and a di ...

Hydropower plants play an important regulatory role in the large scale integration of volatile renewable energy sources into the existing power grid. This duty however requires a continuous extension of their operating range, provoking the emergence of com ...

Objective To evaluate the effects of electrically assisted movement therapy (EAMT) in which patients use functional electrical stimulation, modulated by a custom device controlled through the patient's unaffected hand, to produce or assist task-specific up ...

An endoscopic device for photoacoustic imaging, including a multimode optical fiber having a distal end and a proximal end, a light source to provide a light beam to the proximal end of the multimode optical fiber, a transducer to capture acoustic waves th ...
