Working his muscle

I called a neighbor, who is a physical therapist, asking if there were exercises Ethan could do to strengthen his quad muscle and help with the pain in his tendon.  She came down and told him of some exercises and then hooked him up to a "taser" (as Ethan calls it).  The problem was that Ethan still has a fracture so the electrical jolt went right to his break and he was in so much pain.  She left it for him saying that he needed to use it because it would help his muscle get back to working order. But I don't think he used it again.  It did prompt him to start the exercises she gave him religiously.  He would sit in class and be moving his leg side to side, front to back, etc.  It has really helped and he has been able to lift his leg easier and has been getting his strength back.  His left thigh is still really skinny but he will work on it when he can walk again.
