Abstract: A method and apparatus for pharmacological control of spastic urethral sphincters, particularly in patients with spinal cord injuries, includes a special monopolar electrode/needle (30) adapted for insertion through a cystoscope (46) in electrical isolation therewith but connection with an electromyograph (12) for precise determination of injection sites so that a toxin, such as botulinum A, can be injected directly into skeletal muscle tissue, rather than connective tissue, to denervate and thus relax the sphincter.

Abstract: An improved method and apparatus for mechanical stimulation of nerves to evoke reflexive response, particularly sacral reflex latentency, comprises a hammer (30) having opposite distal and proximal ends. A normally open switch (36) with an extending switch arm (38 ) is mounted on the distal end of the handle (32) and positioned to close upon impact. The switch (36) is adapted for connection to an electromyograph. The switch (36) is preferably partially recessed within an enlargement (40) of the distal end of the handle (32). The switch (36) closes in response to tapping on the patient with the hammer (30) to effect manual stimulation and trigger recording of the reflexive response sensed via an electrode (26).
