Medical History
Giles has been diagnosed with Amyotrophic lateral sclerosis and is currently confined to a wheelchair as he is paralyzed below the waist. He has become depressed as he has realized that the disease's progressive effect is slowly paralyzing his diaphragm. Although he has trouble breathing, his condition has left him unable to exercise the type of breath control he requires in order to play the trumpet.
