Abstract
Two hundred and twenty-two adult crawling poliomyelitic cripples were investigated. Analysis showed that bilateral lower limb paralysis with or without trunk involvement was the most common residual lesion. Remarkably paralysis was confined to a single lower limb in six cases. The various crawling patterns can be classified into six broad groups which are described and illustrated. It is suggested that in a developing country this classification has a practical application in the assessment of patients for rehabilitation to crutch walking. Subjects in the "true quandruped progression" and "squatting gait" categories generally have an excellent potential for rehabilitation, as often do those in the "infant-like crawl" group. Caution should be exercised in attempting crutch walking for those in the "body-dragging" group, and there seems little indication for attempting to establish upright walking for those in the "buttock pivoting" and "minimal movement" groups.
