title: Modification of human spinal stretch reflexes: preliminary studies.
abstract: Modulation of the human spinal stretch reflex (SSR) may be important in treating hyperactive reflexes or may be a tool to enhance normal performance. Eight of 9 subjects given feedback of biceps brachii SSR amplitude and instructed to increase (uptrain) or decrease (downtrain) this response were able to do so in the appropriate direction. These results imply that, as in non-human primates, SSR amplitude can be modified.
