The body is an intricate machine. Every motion made is a reflection of that fact. Whenever the body is moved or put into a position that is unnatural, pain or injuries usually follow. In the athletic training profession one of the biggest parts of the job is the prevention of injuries. So many athletic injuries are the result of some biomechanics movement that could've been fixed with proper training and strengthening. One tool that is widely gaining use is the Functional Movement Screen (FMS) created by Lee Burton in 1997.
The functional movement screen is a set of seven tests of coordination and strength (including core) used to document movement patterns that are essential to normal function. When used, the FMS readily identifies functional limitations and asymmetries (functionalmovement.com). After proper training, the screen can be used by an athletic trainer, personal trainer, strength and conditioning coach or any other medical professional because it only requires the ability to observe basic movement patterns already familiar to most athletic professionals.
When used as an assessment tool, the FMS should be introduced prior to participation in physical activity to determine deficits that could be overlooked during traditional medical evaluations (perform better.com). When risk factors are identified early, they can be addressed which reduces the chance of injury and improves performance.
