Validity of heart rate indexes to assess wheeling efficiency in patients with spinal cord injuries

Study design: Cross-sectional study. Objectives: To validate heart rate (HR) indexes for the evaluation of energy expenditure during wheelchair propulsion in people with spinal cord injury (SCI).

Description
Summary:Study design: Cross-sectional study. Objectives: To validate heart rate (HR) indexes for the evaluation of energy expenditure during wheelchair propulsion in people with spinal cord injury (SCI). Setting: SARAH Rehabilitation Hospital Network—Brasilia, Brazil. Methods: Forty-eight men aged 29.0±7.8 years with a SCI between C6 and L3 causing complete motor impairment were enrolled in the study. The assessment consisted of 5 min of rest while seated in the wheelchair, followed by 5 min of wheelchair propulsion at a self-selected comfortable speed. The main outcomes measured were oxygen consumption, HR, physiological cost index (PCI), total heart beat index (THBI) and propulsion cardiac cost index (PCCI). Results: Using oxygen uptake as gold standard, the highest correlations were found between this and PCCI ( r =0.59, P
