Objective:  The present study aimed to assess the effect of intensive rehabilitation combined with hyperbaric oxygen (HBO2) therapy on gross motor function in children with cerebral palsy (CP). Methods:   We carried out an open, observational, platform-independent study in 150 children with cerebral palsy with follow-up over eight months to compare the effects of standard intensive rehabilitation only (control group n = 20) to standard intensive rehabilitation combined with one of three different hyperbaric treatments. The three hyperbaric treatments used were: air (FiO2 = 21%) pressurized to 1.3 atmospheres absolute/atm abs (n = 40); 100% oxygen pressurized at 1.5 atm abs (n = 32); and 100% oxygen, pressurized at 1.75 atm abs (n = 58).

Each subject assigned to a hyperbaric arm was treated one hour per day, six days per week during seven weeks (40 sessions). Gross motor function measure…
