Abstract

IN AN EARLIER paper published in the Archives,1 data were presented relating to the rate of advance of the Hoffmann-Tinel sign in regenerating nerves. From an examination of these data it was concluded that regenerating sensory dendrites grow distally at a progressively diminishing rate. At the same time, attention was directed to the difficulty of obtaining suitable clinical material on which repeated observations could be made at frequent intervals during the critical period of recovery, a difficulty which probably explained why this feature of regeneration was generally neglected. This defect can be remedied only by collecting additional data whenever and wherever the opportunity occurs for conducting successive examinations of suitable clinical material. Nathan and Rennie2 devoted attention to an evaluation of the Hoffmann-Tinel sign, but in their paper they did not refer to the rate of descent of the sign. In a later paper, Napier3 illustrated a
