What is the english medical term for the filipino tagalog folklore word "Pasma"?

[Rommel S]

Sufferrers tend to have this shaking hand sensation (later in life) and they get that from hitting the showers immediately (and not resting a considerable amount of time) after a strenuous activity...Many athletes do this and i have been told that there are cases prevalent and most old people in the Philippines will tell you it exists.....do you know the english medical term for this?

Parkinson's is a shaking hand in later life but there's no correlation to taking showers after exertion.
