The Ten Euro Neurotest: a new test of finger dexterity proves reliable in controls and patients with Huntington's disease

Introduction: In clinical practice and in research settings, neurologists need standardized motor tests to assess symptom severity and evaluate therapy. Unfortunately, only few motor tests have been formally validated. More specifically, validated simple tests of finger dexterity are lacking. We introduce a new quantified test of finger dexterity, called the Ten Euro Neurotest (TEN), that is easy and fast to use and may be easily standardized across different study centers. Methods: The TEN is performed as follows: ten coins of one euro are aligned on a straight line in the middle of a plain A4-sized paper. The…
