11. Tibia length between 13.4 inches (33.9 cm) and 22 (55.9 cm) inches measured between the knee joint and bottom of the foot.

12. In general good health and able to tolerate moderate levels of activity.

13. Blood pressure and heart rate within established guidelines for locomotive training:

At rest; Systolic 150 or less Diastolic 90 or less and Heart rate 100 or less Exercise; Systolic 180 or less Diastolic 105 or less and Heart Rate 145 or less

Exclusion Criteria

Uncontrolled seizures, musculoskeletal injury, fracture or lower-limb surgery in past year.

16. Known history of pulmonary disease limiting exercise tolerance or history of cardiac disease 17. Psychopathology, or other condition that the physician or investigator, in his or her clinical judgment, considers to be exclusionary to safely use an exoskeleton.

18. Severe concurrent medical diseases, illness, systemic or peripheral infection 19. Dizziness or headache with standing 20. History of autonomic dysreflexia 21. Orthostatic Hypotension: Decrease in Systolic BP > 20, Diastolic BP > 10 upon standing from a seated position.
