AB To the Editor:— 
    I wish to reply to Dr. Rentschler's comments (208: 2337, 1969) concerning my modification of Tinel's percussion test for evaluating intraspinal sensory nerve root involvement (208:152, 1969).I stated that the use of Tinel's percussion test for evaluating peripheral nerve lesions was well known, and that I was suggesting a modification of this test for diagnosing involvement of any spinal sensory nerve root which innervated a cutaneous dermatomere. I chose the sixth cervical root as an example because it is frequently compressed or irritated by cervical disks or osteophytes. However, my comments concerning the manner of doing the test and its interpretation were applicable to any sensory dermatomere in the body. For example, the eighth cervical dermatomere supplying the little finger, and the mesial surface of the ring finger; the fifth thoracic dermatomere which crosses the nipple line; or the fifth lumbar dermatomere which includes the
