About

The purpose of this study is to develop and test a VR training system that integrates GFT AI with virtual obstacle scenarios that, when compared to a sham-VR training system, is hypothesized to increase neuromechanical and perceptual-motor fitness, decrease collision frequency and impact forces for soccer athletes, during a single training session and also when assessed at approximately 1 week and 1 month following training.

Full description

Player collisions cause over 70% of concussion injuries in contact sports, in addition to 50% of lower extremity injuries and 40% of catastrophic knee ligament injuries. The majority of these collisions are unanticipated, and associated with reduced neuromechanical and perceptual-motor fitness underlying an athlete's adaptability to on-field conditions. Thus, training collision anticipation necessitates a method that taps into neuromechanical and perceptual-motor fitness. Virtual reality (VR) is a tool that can target these mechanisms, while providing a safe, well-controlled environment for assessment and training. The current proposal innovates on VR with the integration of genetic fuzzy tree (GFT) artificial intelligence (AI) to drive scenario configuration designed to target modifiable mechanisms and tailored to the individual athlete's performance capabilities, for the optimization of behavior modification and skill transfer. The current study will examine test a GFT AI-driven VR collision anticipation training compared to a sham-VR training system in healthy soccer athletes.

45 participants in 2 patient groups

VR Obstacle group

Experimental group

Description:

Initial Visit: navigates a cluttered array of fixed and moving virtual obstacles to reach a way-point (goal) as fast and efficiently (avoiding obstacles) as possible. In each block, task difficulty (i.e., complexity) will increase linearly, regardless of success or failure (≥ 1 collision before reaching the goal). Second (Training) Visit (randomized into two groups):

Treatment:

Other: GFT AI training

Agility Group

Experimental group

Description:

Initial Visit: Completes a soccer ball dribbling agility task in which they must dribble a soccer ball toward an artificial way-point, while avoiding artificial obstacles overlaid onto the real world via a Microsoft Hololens augmented reality display. Second (Training) Visit

Treatment:

Other: GFT AI training
