Finger tapping test catches early, subtle nerve damage in hATTR-PN

A computerized test that measures how quickly and accurately people perform finger tapping and hand movement tasks was able to detect subtle motor problems in people with hereditary transthyretin amyloidosis with polyneuropathy (hATTR-PN) earlier than some standard clinical assessments.

That’s according to a study in Italy that evaluated hand motor performance in more than 100 hATTR-PN patients using the Hand Test System (HTS), which uses a glove with five sensors. The HTS was tested across disease stages and examined potential associations with standard measures.
