DMD and muscular dystrophy: Although the patient has an in-frame deletion of DMD exon 5 that predicts a Becker’s muscular dystrophy diagnosis, his signs and symptoms of prominent pelvic girdle weakness (full timed Gower’s in 3.2 seconds); plantigrade stance; run with increased upper extremity swings and a waddle; unable to extend his hips fully against gravity for the table top manoeuvre; rising from a chair by turning his body, followed by hand push off the chair and waddling gait with lordosis with a heel-toe progression warranted further investigation.
