Participant Flow

21 patients were enrolled in the study. Of these, 17 steroid-naive boys with DMD were enrolled into the 12 month twice weekly steroid arm and 2 of the 17 underwent cycle exercise training from month 6 to 12. Of the 21 enrolled patients, 4 boys on daily steroids were enrolled into a 6-month exercise training arm.

Participant milestones
Measure
Twice Weekly Glucocorticoid Without Exercise
Steroid naive patients were enrolled and administered low-dose prednisone (dose of 0.75 mg/kg per day) twice weekly for 12 months.
Daily Glucocorticoid With Exercise
Patients on daily glucocorticoids for at least 3 months will undergo 6 months of structured, supervised and home-based exercise training. In-home Exercise Training: For boys on current standard of care (daily glucocorticoid use), 6-months in-home, remotely supervised exercise training program involving a combination of aerobic and isometric leg strength exercises.
Twice Weekly Glucocorticoid With Exercise
Steroid naive boys with DMD were enrolled and underwent the twice weekly steroid protocol for 6 months; exercise was initiated at 6 months while continuing twice-weekly steroids.
