Lower extremity blood flow and responses to occlusion ischemia differ in exercise-trained and sedentary tetraplegic persons

30 subjects including 10 sedentary tetraplegic men, 10 tetraplegic persons previously habituated to electrically stimulated cycling exercise for 0.4 to 7 years, and 10 nondisabled controls.
