Clinical examination in PNIs (based on [89,93]).

Test	Details
Manual muscle testing	-aims to identify specific weakness patterns, helping in the proper localization of the nerve injury -muscle strength is graded from M0 (no muscle power) to M5 (full muscle power) -evaluation is performed using grade M4 (power against moderate resistance)
Sensory collapse test	-the patient must resist applied force before and after the examiner scratches/touches the skin over the suspected nerve compression site -a focal nerve compression causes a temporary loss of muscle strength
Pain testing	-allodynia is evaluated at the compression site
