The primary purpose of this randomized, controlled, multicenter study is being conducted to determine the efficacy of early in-patient exercise, when used as an adjunct to standard of care (SOC), in improving recovery of adults from burns. The secondary purpose is to assess the efficacy of a personalized, structured, and quantifiable exercise program (hereafter referred to as MP10) carried out soon after admission until hospital discharge (including during the BICU stay and time on ventilation). This objective will be met through a multicenter trial in children and adults (7 - 60 years) with ≥30% TBSA burns. Outcome variables will include BICU days, ventilator days, hospital days, peak treadmill time, and lean body mass and psychosocial function (See Section 8 for details).
