Intensity of physical activity as a percentage of peak oxygen uptake, heart rate and Borg RPE in motor-complete para- and tetraplegia.

Using current classification systems, eleven commonly performed activities were categorized in relative intensity terms, (light, moderate and vigorous) based on percent of VO2peak, HRpeak and Borg RPE. This categorization enables clinicians to better guide persons with SCI to meet required physical activity levels.
