tone testing
Last reviewed 01/2018
During the testing for tone in the neurological examination of the upper limb, the examiner should seek to answer the following questions:
- is there increased tone?
- if there is increased tone, is it clasp knife ie spastic hypertonicity, or is it lead pipe - ie parkinsonian?
- is there decreased tone? This is very hard to judge without a great deal of clinical experience.
- is there cog wheeling?
