Article Abstract
An important quality of upper limb force estimation is the repeatability and worst-case performance of the estimator. The following paper proposes a methodology using an ensemble learning technique coupled with the fast orthogonal search (FOS) algorithm to reliably predict varying isometric contractions of the right arm. This method leverages the rapid and precise modelling offered by FOS combined with a univariate outlier detection algorithm to dynamically combine the output of numerous FOS models. This is performed using high-density surface electromyography (HD-SEMG) obtained from three upper-arm muscles, the biceps brachii, triceps brachii and brachioradialis. This method offers improved performance over other HD-SEMG and SEMG based force estimators, with a substantial reduction in the number of channels required.

Background: Neurological diseases such as stroke or Parkinson's disease are often accompanied by weakening or loss of proprioception, which seriously affects the motor control ability of the patients. However, proprioception rehabilitation is challenging due to the pain caused by impaired joints and the hard efforts that patients have to make during training. This study investigated the cross-transfer effect of short-term visuomotor training to the untrained wrist from the trained wrist, from both views of behavioral results and brain activity analyses.

Background: The mechanisms contributing to epidural-related maternal hyperthermia remain unclear. One explanation is that blockade of cholinergic sympathetic nerves prevents active vasodilation and sweating. However, it is not known how labour epidural analgesia affects cutaneous sympathetic function.

Introduction And Importance: Monteggia lesions combine a fracture of the ulna with dislocation of the radial head. Monteggia-like variants add a radial head fracture. We report a unique Monteggia-like injury with a bifocal radial fracture and subcutaneous enucleation of the radial neck, which does not fit existing classifications.

Purpose: Children with incomplete recovery from Brachial Plexus Birth Injury (BPBI) experience varying degrees of upper limb impairment, and 20-30% require interventions to optimize function. A psychometrically validated measure of upper limb activity capacity is essential to guide shared clinical decisions for surgical and rehabilitation interventions.
Materials And Methods: Following the Joanna Briggs Institute Manual for Evidence Synthesis, this systematic review included studies on the measurement properties of the Brachial Plexus Outcome Measure (BPOM) - Activity Scale, a performance-based outcome measure of upper limb activity capacity in children with BPBI.
