I especially appreciate the discussion on the goal of using consistent force when diagnosing and treating patients.  Quality should improve when all therapists use a consistent and predictable range of force during treatment of patients.

FORCE SENSING

Jeannine--Fascinating post.  My father is in assisted living and I definitely know there is a tremendous need for devices as you have described.  The technology to bring about force sensing must be "cutting-edge" or maybe I have not been paying attention.  I think I know the answer to this one but, are these devices on the market today?  If not, when might we see commercialization?  Another question, how is feedback delivered in the case of surgical devices?  Is there a monitor giving the force; i.e. pressure and how are limits established for determining the level of force relative to the tissue in question?  Again, great post.

Force sensing in medical devices is really a natural, and I believe that's because medical device engineering is a little different than consumer products.  In medical devices the user is always in charge.  The philosophy is to warn the physician if he is exceeding pre-programed safety algorithms, but to always allow the physician to do what he needs to treat the patient.  So in a consumer device you might limit the force available, but in a medical device you'll allow the physician to use additional force, but the device will monitor the force and warn the physician that normally safe limits are being exceeded.
 
I say this is different than consumer devices because medical devices always assume that the user is responsible and is in charge of the device operation, while in consumer devices that responsibility is being engineered out of the product.
