Hello Val, The P.T. David Ogden address is: 10632 N. 39th Ave. Phoenix, Az. Perhaps if the demand is great we can reissue the 8 tapes we made. The approach stresses performance of motor activities that challenge the P.D.compromised set of responces andperformace. For example, seated perform reciprocal movement of right foot on racket ball while toe heeling with left. The hands and arms open and close while the right is circling. Be sure a helper uses a gait belt when walking, command might be Two steps backwards to the right and Four steps to the left on a diagonal. The program is ongoing and very successful from a P.D> point of view.Personally I have no fractures since participating. Please recognize comittment is necessary for success! Hope this explains! phyllis.
