Exercise Testing Using Upper Extremity Ergometry in Pediatric Spinal Cord Injury

Purpose: To describe an upper extremity ergometer test for children with spinal cord injury (SCI) and examine differences based on injury level for peak heart rate (HRpeak), oxygen uptake (VO2peak/kg), and peak power output per kilogram (Wpeak/kg). Methods: Twenty-nine children with motor complete SCI participated. Nine had low cervical (C7, C8), 9 had upper thoracic (T1–T4), and 11 had mid/low thoracic (T5–T11) SCI. HRpeak, VO2peak/kg, and Wpeak/kg were compared based on these 3 injury level groupings. Results: HRpeak (p = 0.013), VO2peak/kg (p = 0.041), and Wpeak/kg (p = 0.001) differed between groups. The mid/low thoracic group had the highest values for each variable. Conclusions: The differences in HRpeak, VO2peak/kg, and Wpeak/kg were consistent with exercise effects reported for adults with SCI. Further research is needed to develop an appropriate standardized ergometric test for children with SCI.
