NCT06792539
The goal of this clinical trial is to evaluate the safety and effectiveness of the Polymotion Hip Resurfacing (PHR) System compared to total hip arthroplasty, for adults who require hip resurfacing arthroplasty due to 1) non-inflammatory arthritis (degenerative joint disease) such as osteoarthritis, traumatic arthritis, or 2) mild dysplasia/developmental dislocation of the hip (DDH) up to Crowe Grade 1.
NCT07561372
The purpose of this study is to better understand how electrical or magnetic stimulation affect the nervous system by optimizing the way researchers measure muscle responses. The relationship between stimulation intensity and muscle response is described by "neural recruitment curves," which are critical for monitoring the state of the nervous system during therapies like transcranial magnetic stimulation (TMS) and spinal cord stimulation (SCS). This study tests a new, real-time computational approach based on our previously developed methods (Hierarchical Bayesian models) to estimate these recruitment curves more efficiently. The primary goal is to use this model to dynamically guide the experiment, automatically selecting the optimal stimulation intensities to test. The investigators hypothesize that this optimized approach will accurately estimate the entire recruitment curve, or specific targets components of it like the motor threshold, using significantly fewer samples than standard methods. By reducing the number of measurements required, this approach aims to decrease experimental time and minimize participant burden, making future TMS and SCS therapies and experiments more feasible and efficient.
