Experts vs. Novices

"So when confronted with a problem, the expert applies her knowledge problem schema by working forward from the information given to solve the problem. They tend to work from the known to the unknown. The expert has solved many similar problems and recalls schemas easily. The novice, on the other hand, tends to work backwards. They begin with the unknown in the problem and try to use trial and error or incomplete schemas to solve it."
Karl Kapp

SQUARE 1 works forward from the most isolatable and testable functional unit of movement, joint actions, and works towards more complex and unknown elements. SQUARE 1 practitioners tests which actions can and cannot tolerate load. The actions that are intolerant to load are addressed. By restoring function to the elemental raw materials of movement, the downstream components immediately improve (motor patterns, motor learning, outcomes). The SQUARE 1 methodology fits the definition of expertise according to Karl Kapp.

Most approaches that are commonly used by today's physical therapists and personal trainers to improve movement attempt to work backwards from observed poor outcomes such as a movement restriction or pain-provoking movements. Based on their superficial observations, a motor learning (exercise) program is usually prescribed. Basically it's the old, if it's tight stretch it, if it's weak strengthen it. Sounds good but it's totally a JV approach. To make it sound extra science-y, some pros might throw in terms like patterns and motor control. Mr. Kapp is nice and calls the traditional industry approaches trial and error. I say the vast majority of the industry is just guessing.
