Now, this is not to say this is your dx but MS is a tricky dx. The surefire way to dx PD is if the Sinemet works
, you have PD. The wrist cogwheel test is taking
your wrist into the air and turning your hand in circles at your wrist, both ways; each hand. If there is difficulty in smoothness and fluidity of movement and if it is jerky, this could lead to a Parkinson's dx. Again, the true test is the drug, Sinemet.
Good luck to you.
Hope, have HOPE.
