Energy Cost Index as an Estimate of Energy Expenditure of Cerebral‐palsied Children During Assisted Ambulation

Abstract: SUMMARY The energy expenditure of cerebral‐palsied children ambulating with bilateral quad canes and wheeled walkers was estimated, using average heart rate and speed of walking. An energy cost index (average number of heart rates per unit distance walked) was derived to allow for varying speeds among patients. Children were then categorized into those who had a lower energy cost index when using quad canes and those who had a lower index when using walkers. This made it possible to offer treatment recommendat… Show more

“…This early loss of ambulatory capacity can be explained by studies on the high energy cost of ambulation in those with CP. [22][23] The avoidance of undue fatigue by relinquishing independent walking is confirmed by other authors. [24][25][26] This idea is given further weight by a recent study on fatigue by Jahnsen et al 27 in which they showed that mean scores on total fatigue and physical fatigue were significantly higher in participants with CP, but no statistical relationship between fatigue and level of motor impairment was found.…”

“…Resting heart rate, walking heart rate and velocity are used to calculate either the Energy Efficiency Index (EEI) [2] or the Physiological Cost Index (PCI) [3]. These indexes are considered reasonable alternatives to direct measurement because of the linear relationship established between heart rate and oxygen consumption at submaximal workloads [4]. In addition, the assessment of heart rate can be performed with minimal equipment and expertise making this methodology easily applicable in a clinical setting.…”

“…The disadvantages of directVO 2 measurements include the cumbersome nature of the testing process and high costs of data collection systems. Several indices have been developed to estimate energy cost andVO 2 from heart rate (HR), with the assumption that linear relationships exist between HR andVO 2 in individuals with motor disorders and in children with CP [16,17].…”
