Effects of immersive virtual reality-based action observation training integrated with focal muscle vibration on upper extremity in a patient with chronic disability following stroke: a single-subject study.

Background: The association of different sensory inputs enhances brain plasticity in patients after stroke, but no studies have associated Action Observation Training (AOT) delivered in immersive virtual reality (VR) with Focal Vibration (FV) to elicit a kinesthetic illusion coherent with the observed task to improve motor function.

Objective: The study aimed to evaluate the feasibility of AOT delivered in immersive VR integrated with FV of upper limb muscles on manual dexterity in patients with chronic stroke.

Methods: A single-subject study was conducted (A-B design).

Human neutralizing antibodies to cold linear epitopes and subdomain 1 of the SARS-CoV-2 spike glycoprotein.

Emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants diminishes the efficacy of vaccines and antiviral monoclonal antibodies. Continued development of immunotherapies and vaccine immunogens resilient to viral evolution is therefore necessary. Using coldspot-guided antibody discovery, a screening approach that focuses on portions of the virus spike glycoprotein that are both functionally relevant and averse to change, we identified human neutralizing antibodies to highly conserved viral epitopes.
