The PNF diagonal patterns covered by this course apply to the legs and arm.  There are also PNF diagonal patterns for the upper and lower trunk, head and neck.  

Although not covered, both trunk and neck will be demonstrating varying degrees of D1 and D2 movements as the client performs the PNF patterns with the arms and legs.  Resistance by the water to arm and leg movements during performance creates irradiation facilitating trunk and neck musculature.
