Interface pressure mapping is often used in seating clinics to determine the effects of different cushions. Currently, therapists and clinicians cannot easily compare repeated assessments. Longitudinal analysis and self-registration (LASR) is a new technique, developed by our team, to get rapid three-dimensional analysis of pressure maps. LASR was tested on measurements from neuromuscular electrical stimulation experiments. LASR showed that seating pressure distributions improve over time with electrical stimulation of paralyzed buttock muscles in people with spinal cord injury. These changes may reduce the risk of pressure ulcer development. Using LASR in seating clinics will help clinicians decide which cushion is best for the user.
