Research in the field of neuromuscular disease is increasing at an astonishing pace. However, there is no current standardization in the evaluation of the ambulatory status of patients.

Unlike the traditional binary stratification, this method adds a third stratification which is very important for clinical trial planning and an accurate assessment of the ambulatory status of patients.
