Response of muscle spindle primary endings to static stretch in acute and chronic spinal cats.

摘要: To evaluate fusimotor activity, the response of muscle spindle primary endings to static stretch was recorded from group Ia fibers in 8 control cats and 31 at 3, 6, 14, 30, 60 days after lumbar spinal cord transection. The responses clinical status each were compared with those group. At 3 transection, hypotonic mildly hyperreflexic. Spindle significantly depressed. By day hypertonic significant recovery had occurred, although still depressed levels. responses, hypertonia, hyperreflexia continued increase 30. this time, remained depressed, markedly A change activity or did not occur 30
