Purpose: We analyzed the evolution and pattern of heart rate (HR) during the 12-minute wheelchair propulsion field test (WPFT) and compared the peak HR (HRpeak) from the WPFT to the HRpeak obtained in the progressive cardiopulmonary exercise test on arm cranking ergometer (ACT). We aimed to determine if the field test detects the HRpeak consistently and could be used in clinical practice. Methods: Eleven wheelchair-using children and adolescents with myelomeningocele (aged 8–15 y) performed a maximal ACT and a 12-minute WPFT. HR was recorded continuously at rest, during each minute of the tests, and at recovery. Mixed analysis of variance was used to compare the variables at rest and peak. Bland–Altman plot and Lin’s concordance correlation coefficient were used to show agreement between the tests. Results: During minute 2 of the WPFT, participants reached 73%–96% of the HRpeak values recorded in the ACT. From minutes 4 to 12, participants reached HRpeak values ranging 86%–109% of the values recorded in the ACT. There is agreement between the ACT and the WPFT tests. Conclusion: WPFT with minimal duration of 4 minutes may be an alternative tool to obtain HRpeak in children and adolescents with myelomeningocele.
