Design of a rehabilitation device for athletes with acute knee sprains in a soccer academy

Introduction: This study addresses the design of a rehabilitation device for athletes suffering from acute knee sprains within soccer academies. Knee injuries are among the most prevalent in sports, significantly impacting athletic performance and requiring effective rehabilitation solutions. Traditional rehabilitation approaches often lack accessibility and customization, prompting the development of innovative devices that align with athletes' specific needs.Methods: A mixed-method approach was employed, integrating qualitative and quantitative analyses. Data collection included interviews with physiotherapists and athletes, complemented by field observations in soccer academies. The design process combined User-Centered Design (UCD) and TRIZ methodologies to identify and resolve contradictions, leading to an optimal solution. Tools such as CAD software and rapid prototyping techniques facilitated the development of the device.Results: The resulting device demonstrated effectiveness in aiding recovery from acute knee sprains. Athletes reported reduced pain, improved mobility, and shorter recovery times. Quantitative metrics, such as muscle strength and joint stability, indicated significant improvements, while qualitative feedback highlighted the device's comfort and user-friendliness.Conclusions: The rehabilitation device represents a novel contribution to sports medicine, particularly for soccer academies. Its innovative design addresses the specific requirements of athletes, enhancing their recovery process and performance. Despite its potential, further studies are needed to validate its efficacy across broader populations and diverse sports disciplines. This research underscores the importance of integrating design, technology, and medical expertise to develop impactful rehabilitation solutions.
