Reliability of a recumbent stepper submaximal exercise test after traumatic brain injury.

Purpose: To determine the test-retest reliability of a total body recumbent stepper (TBRS) submaximal exercise test and to examine its relationship with other measures throughout the International Classification of Functioning that are indicative of overall health in individuals with traumatic brain injury (TBI).

Methods: Twenty-three ambulatory individuals with severe, chronic (>6 mos) TBI completed a TBRS submaximal exercise test, 6-minute walk test (6MWT), and Mayo Portland Adaptability Inventory (MPAI-4) at initial testing. A repeat TBRS submaximal exercise test was conducted 4-7 days later.
