Design outcomes

Primary

Measure	Time frame	Description
Numerical Rating Scale (NRS)	Change from baseline to minutes 30, day 1, week 1, 2, 4, 6 after the block	Pain Score Change The 11-point NRS consists of numbers between 0 and 10 where 0 indicates no pain and 10 indicates maximum pain. The patient is instructed to identify one number between 0 and 10, which is best representative of their pain intensity.
