“…The combination of the relatively high VO 2peak with the low PO peak supports the finding that wheelchair propulsion is mechanically less efficient than arm-cranking. 24 Measuring VO 2peak and PO peak VO 2peak and PO peak have proven valid and sensitive outcome measures for the assessment of physical capacity, 1 and should be included in the follow-up of persons with an SCI. The outcome of the maximal exercise tests were expressed as peak levels of oxygen uptake and power output (instead of maximal levels), because some subjects may have been able to activate a larger muscle mass, either through activation of the lower limbs (eg in those with incomplete lesion), or without the restraints from overuse and fatigue of the upper extremities.…”

“…Secondly, peak heart rate is not a valid measure of physical capacity in SCI, and is not sensitive to change during training. 1,34,75 Reasons for this may be that upper body exercise is limited by local fatigue and overuse (rather than cardiovascular strain), and that peak heart rate varies too much in persons with a tetraplegia. 20,21,24,71 Overall, a positive selection is shown which will bias the results.…”

“…1 It is reduced in persons with a spinal cord injury (SCI) by the direct loss of motor control and sympathetic influence below the level of lesion. Additionally, the majority of persons with an SCI will be wheelchair users and dependent on arm work for mobility and activities of daily living.…”

“…This could be attributed to the disparity in population, methodology and presentation of results, which hamper comparisons and generalization. 1,3,10 Furthermore, few studies have addressed more than one component of physical capacity simultaneously. 1,3,12 Therefore, the purpose of this study was to integrate evidence on different components of physical capacity in SCI, by critically analysing absolute values and (in)consistencies in the literature.…”

Study design: Review of publications. Objective: To assess the level of physical capacity (peak oxygen uptake, peak power output, muscle strength of the upper extremity and respiratory function) in wheelchair-dependent persons with a spinal cord injury (SCI). Setting: Erasmus MC, University Medical Centre Rotterdam, The Netherlands. Methods: Pubmed (Medline) search of publications from 1980 onwards. Studies were systematically assessed. Weighted means were calculated for baseline values. Results: In tetraplegia, the weighted mean for peak oxygen uptake was 0.89 l/min for the wheelchair exercise test (WCE) and 0.87 l/min for arm-cranking or hand-cycling (ACE). The peak power output was 26 W (WCE) and 40 W (ACE). In paraplegia, the peak oxygen uptake was 2.10 l/min (WCE) and 1.51 l/min (ACE), whereas the peak power output was 74 W (ACE) and 85 W (WCE). In paraplegia, muscle strength of the upper extremity and respiratory function were comparable to that in the able-bodied population. In tetraplegia muscle strength varied greatly, and respiratory function was reduced to 55-59% of the predicted values for an age-, gender-and height-matched able-bodied population. Conclusions: Physical capacity is reduced and varies in SCI. The variation between results is caused by population and methodological differences. Standardized measurement of physical capacity is needed to further develop comparative values for clinical practice and rehabilitation research.
