The Volcano theraputty exercise supports smooth coordinated movements of fingers and thumb working together (lumbricals). The volcano can also promote the strengthening of the smaller (interossei) muscles to support function in everyday activities. Start by firmly securing the pancake to the table by pressing the edges down, then place your fingers and thumb lightly around the edge of the pancake. Press fingers and thumb into putty and slowly pull fingers together towards the centre. Carry out exercise with both hands.
