• Aim– Investigate physical exertion rate of robotic-assisted tilt-
table therapy (RATTT) in patients with spinal cord injury (SCI).
– Compare response of patients with motor-complete SCI (cSCI) and motor-incomplete SCI (iSCI).
• Relevance– RATTT may provide strong training stimulus to
complement conventional physiotherapy.– RATTT may both increase orthostatic tolerance and
attenuate decline in aerobic fitness.

Method• Participants – 3 cSCI.– 3 iSCI.
• Protocol– 5 discrete phases, 5 min each
• Measures– Continuous: pulmonary gas exchange, ventilator,
heart rate.– Final 30 s: blood pressure.

Method• Testing phases:– 1. Subject supine; no stepping profile imposed.– 2. Subject tilted to 70 from horizontal at 0.06 rad/s.– 3. Robotic orthoses provided full guidance force. • cSCI: No volitional effort.
– 4a. iSCI only. Guidance force reduced, volitional effort increased.
– 4b. Functional electrical stimulation (FES) applied.• iSCI subjects instructed to continue volitional participation.

Results• iSCI– O2 uptake, respiratory exchange ratio (RER), minute ventilation,
heart rate:• Significantly increased in Phases 4a and 4b only.
• cSCI– Minute ventilation:
• Small but significant increase.• iSCI vs cSCI– O2 uptake, RER, minute ventilation, heart rate:
• No difference in Phases 1-3.• Significantly larger in Phase 4b for iSCI.
– Mean arterial pressure significantly larger in all phases for iSCI.

Conclusion• Volitional effort led to increased cardio-pulmonary
and ventilatory response during RATTT.– Sustained or improved with addition of FES.
• Patients with iSCI:– Period of training with volitional contribution could
improve cardiopulmonary and ventilatory fitness.
• Patients with cSCI:– FES-assisted RATTT may be sufficient to attenuate
fitness losses.
