Cerebral Vascular Accident (CVA)/Stroke

This is a prospective, multi-center, randomized controlled study. The goal of the study is to assess the safety and effectiveness of the Resonova® CHORDS® Cerebral Protection System in capturing and removing embolic debris during Transcatheter Aortic Valve Replacement (TAVR). A total of 240 eligible participants will be enrolled and randomized in a 1:1 ratio to undergo TAVR either with the CHORDS® Cerebral Protection System (Test group) or the Sentinel System (Control group).All the participants will be followed up at 30 days and 90 days post-procedure.

The goal of this longitudinal observational study is to learn the course of recovery after stroke. Specifically, in this study we will learn and describe the changes in cognitive, motor and sensory function over time in stroke patients.

The study aims to compare the effects of dorsal-double-layered 10% circumferential reduction (DD-10), single-layered 10% circumferential reduction (S-10), and single-layered no circumferential reduction (S-0) pressure garments on sensorimotor functions, including motor control, dexterity, muscle tone, pain, self-perceived upper extremity function, and quality of life among stroke patients during the 8 weeks of application (Time 1: Baseline, Time 2: Week 4, Time 3: Week 8).

This study is being done to see how errors lead to improvement. Specifically, we are evaluating the errors stroke participants make during an upper extremity exercise program when reaching for a target using their affected arm. Once we understand the participant's reaching errors, we plan to create a customized reaching exercise according to the individual's specific error tendencies which will lead to better performance on movement ability after training.
