Clinical onset

Clinical onset will be when symptoms (pain, parasthesia, weakness) in the hand, in the median nerve distribution, first began. 

Clinical worsening

A clinical course involving periods of remission and exacerbation is common.  There may be progression from intermittent to persistent sensory symptoms, and later, to the development of motor symptoms (weakness).
