This work presents an intention decoding algorithm that can be used to control a 4 degrees-of-freedom shoulder-elbow exoskeleton in reaching tasks. The algorithm was designed to assist the movement of users with upper-limb impairments who can initiate the movement by themselves. It relies on the observation of the initial part of the user's movement through joint angle measures and aims to estimate in real-time the phase of the movement and predict the goal position of the hand in the reaching task. The algorithm is based on adaptive Dynamic Movement Primitives and Gaussian Mixture Models. The performance of the algorithm was verified in robot-assisted planar reaching movements performed by one healthy subject wearing the exoskeleton. Tests included movements of different amplitudes and orientations. Results showed that the algorithm could predict the hand's final position with an error lower than 5 cm after 0.25 s from the movement onset, and that the final position reached during the tests was on average less than 4 cm far from the target position. Finally, the effects of the assistance were observed in a reduction of the activation of the Biceps Brachii and of the time to execute the reaching tasks.

The ongoing conflicts in the Middle East have led to a substantial influx of Syrian refugees, exposing them to severe traumatic experiences and contributing to a range of mental health issues. This systematic review examines psychotherapeutic interventions employed in psychological treatment studies with Syrian refugees, focusing on 22 articles identified across Scopus, PubMed, Web of Science, and ScienceDirect. The review highlights the need for psychotherapeutic intervention for Syrian refugees due to the high prevalence of post-traumatic stress, depression, anxiety, grief, and loss which results from an increased risk of various forms of violence and exploitation.

Introduction: Creutzfeldt-Jakob disease (CJD) is a rare, rapidly progressive, fatal, neurodegenerative disease classified as prion diseases. There are many subtypes of this disease, but information about clinical presentation and investigation findings in Thailand is scarce.
Objective: To describe the clinical presentation, radiological and electroencephalographic characteristics of CJD encountered at Siriraj hospital in the past 10 years (between January 1, 2006 and December 31, 2015).

Introduction: Fibromyalgia (FM) and chronic fatigue syndrome (CFS) are complex central sensitization syndromes that represent an important public health problem. Low cardiorespiratory fitness and muscle function with habitual intolerance to efforts are common characteristics of FM and CFS. This study aimed to examine the effect of a brief multicomponent intervention based on physical activity (PA), nutrition, and chronobiology on movement behaviors (PA, sedentary and sleep time), muscle strength, and cardiorespiratory capacity.

Muscle tone represents a foundational property of the motor system with the potential to impact musculoskeletal pain and motor performance. Muscle tone is involuntary, dynamically adaptive, interconnected across the body, sensitive to postural demands, and distinct from voluntary control. Research has historically focused on pathological tone, peripheral regulation, and contributions from passive tissues, without consideration of the neural regulation of active tone and its consequences, particularly for neurologically healthy individuals.
