Human Assessment Mastery

Most of us are aware of triplaner motion. But when I ask someone how they apply it in training, the usual response is: "I make sure I train all 3 planes...Sagittal, Frontal, Transverse".

While this isn't necessarily wrong. It's not what triplaner motion was intended to teach. Real triplaner motion is being able to look at any task (be it gait, running, lifting, or playing a sport) and understanding how all 3 planes of motion are happening SIMOTANIOUSLY! 

Every lift you do (even if it is a bilateral squat which is predominately sagittal plane) has triplaner motion occurring! The more you understand this, the more your patients will think you can predict the future. As you'll be able to guess what most range of motion limitations are located simply by watching them walk, squat, lunge and reach overhead.
