• Aim– Propose method for assessing vascular flow measured by

transcutaneous O2 pressure (TcPO2) in ischium of physically active and sedentary people with spinal cord injury (SCI).

• Relevance– Risk of pressure ulcers (PUs) higher in people with SCI.– Pressure at interface between wheelchair user and seating

surface may reduce or eliminate peripheral arterial blood circulation, thus causing PUs.

– Physical activity may help prevent PUs.

• Sample: 38 men with thoracic SCI.– 12 physically active, 26 sedentary.

• Assessed distribution of physiological response of tissues under load during sitting via analysis of ischium TcPO2 values obtained by oximeter.– TcPO2 baseline.– Recovery time of TcPO2 after sitting (Trec).– % of TcPO2 of maximum pressure TcPO2.– Mechanic maximal pressure.



System analysis of TcPO2 with TCM400 monitor (Radiometer Medical ApS; Copenhagen, Denmark).



Results• TcPO2 Baseline

– Values were similar for both groups.• Indicates that without pressure, both groups had similar tissue

vascularization in ischial area.

• Trec – Significantly lower (p < 0.05) in physically active group

than sedentary group.• %TcPO2

– Significant differences between groups (p < 0.05) were also found.

• Vascular response of tissue area under pressure seemed to be better in population with SCI who was regularly active than in population with SCI who was sedentary.

• This first pilot study offers interesting line of research in field of physical activity and sport for improving quality of life for people with SCI.
