What is Applied Functional Science?
Applied Functional Science (AFS) presents a distinct paradigm that synthesizes that realms of physical, biological, and behavioral sciences, harmoniously working together to treat patients holistically. This interdisciplinary approach leverages biomechanics influenced by the everyday dynamics of life to pinpoint and address the root causes of injuries.
Incorporating Physical Science, AFS scrutinizes the functional mechanics of joints and muscles, their responses intricately woven into the fabric of daily activities. Biological Science seamlessly applies neuromuscular properties within these activities, uncovering deeper functional insights. On the behavioral front, AFS takes a personalized route, integrating individual motivations and aspirations into bespoke treatment plans.
The Scientific Truth About Movement embodies the convergence of physical, biological, and behavioral sciences. This comprehensive perspective illuminates the mechanics of human motion, guided by the principles, strategies and techniques of PST. This scientific approach to movement extends its application to the golf swing, acting as both a preventative measure against injuries and safeguard against detrimental impacts on the swing itself.
Step into the realm of Applied Functional Science, where the synergy of sciences amplifies the understanding of human movement and propel personalized treatment towards comprehensive wellness. From rehabilitation to enhancing performance, AFS transcends boundaries to foster optimal movement patterns and overall well-being.
