Conditions due to neuromuscular and vascular pathologic processes together with deformities of the lower extremities are generally recognized causes of disturbances in locomotion. The treatment of these disorders embraces the fields of medicine, general surgery and orthopedics. Whenever treatment of such conditions is seriously undertaken, the difficulties accompanying the visual analysis of gait are recognized.
Efforts directed toward the development of methods for recording gait have been less numerous than the apparent need for such clinical advantage would seem to justify. Most of the studies in this country and abroad have been made with a consideration for the physiology of locomotion without reference to the possibility of such studies being of practical value to the various branches of clinical medicine.
We accept the premise that no two people walk alike. We doubt the possibility of determining a normal gait. Our position is comparable to that of Wunderlich's and others in
