Summary:•Cardiac autonomic function is impaired in children after severe TBI.•Cardiac autonomic measures at rest did not change during the sub-acute stage.•Cardiac autonomic measures recovered in part in response to autonomic tests.•Clinical trials of interventions to improve cardiac autonomic function are needed. One of the sequalae of severe traumatic brain injury (TBI) in children is impaired function of the cardiac autonomic control system (CACS) at rest. The CACS response to conventional autonomic tests is little known. To examine the CACS response to conventional autonomic tests in children after severe TBI during the rehabilitation period and to compare with typically developing (TD) children. This study combined a case-control and follow-up design. The severe TBI group (cases) consisted of 33 children aged 9–18 years, 14–142 days after severe TBI who were followed for 8 weeks during rehabilitation. The control group consisted of 19 TD children matched for age and sex. Heart rate (HR) and heart rate variability (HRV) were evaluated with the Polar RS800CX device at rest (sitting), during a handgrip test and during a paced breathing test. At the first assessment, we found lower HRV values at rest and a lower HRV response during the paced breathing and handgrip tests in the TBI group than the TD group (p
