The word "troch" is a rare term that is generally used in the medical field to describe a cylindrical apparatus used in measuring the force of muscles. The word is spelled using the IPA phonetic transcription as /trɒk/, with a silent "h" at the end. The "o" and "ch" are pronounced as in the words "rock" and "church," respectively. The word does not have any commonly used derivatives or variations and is only encountered infrequently in specific medical contexts.
