In your case this appears to be a harmless nuisance rather than indicative of a neurological disorder like Parkinson's disease,ALS,etc. Apparently those maneuvers cause irritability of the median nerve or its branch leading to your index finger as you don't experience this symptom on other occasions. A neurologist or a hand specialist can advise you further if you still have concerns.
