Human walking, or locomotion, is the result of millions of years of human evolution. Our biomechanics, structural alignment, and muscle coordination has been fine-tuned at every step to make our way of walking as energy efficient as possible. Even slight deviations or abnormalities can result in tremendous unnecessary pain and energy expenditure. When it comes to matters of the musculoskeletal system, a proper assessment of gait/walking is often the first step toward a real solution.
