ABSTRACT:
A tubular-frame rocking platform is provided with a wheeled platform. To the structure a resistance rod is selectively locked in a forward part of the chair and extends rearwardly through a rearward element of the chair and is provided with a spring and head. When the occupant pushes back to rock the chair backwards, he does so against the opposition of the spring. This done repeatedly has therapeutic value.
