I have a Hinterberg frame too, however I used to do stab stich on it. My middle finger right hand has bad arthiritis (unfortunately so do my others but this one is the worst) so I have regretfully stored it in a bedroom now. I found the lady's comment who quilted with her index finger instead of middle finger very interesting. I had to import my frame to Australia, we had nothing like it here. I do make some of my quilt piecing on a treadle machine which also has a lovely rythm like hand quilting.
