Table 2.
Validity of the finger tapping test for identifying infratentorial and cervical cord demyelinating lesions in four different settings based on handedness, and location of tap (i.e. thumb tip versus distal thumb crease) across different categories of providers (neurologists, neurology residents, and advanced practice providers)
| Dominant hand, Thumb tip |
Dominant hand, Distal thumb crease |
Non-dominant hand, Thumb tip |
Non-dominant hand, Distal thumb crease |
