Apparatus for use in diagnosing and/or treating neurological disorder

An apparatus for use in diagnosing at least one neurological disorder in a subject, the apparatus comprising:

• (a) at least one first detector device adapted to be held by a hand of the subject and to provide at least one respective first signal containing first data representing a respective force applied to said first detector device by at least one finger of the subject;
• (b) at least one second detector device adapted to be engaged by said at least one said first detector device when held by the subject, wherein said first or said second detector device is adapted to (i) provide at least one respective second signal containing second data representing a position of said first detector device relative to a respective said second detector device and (ii) provide at least one respective third signal containing third data representing an engaging force of said first detector device on said second detector device;
• (c) at least one third detector device configured to directly measure the position of part of an arm of the subject other than the hand, and adapted to provide at least one respective fourth signal containing fourth data representing a position of at least said part of said arm of the subject holding said at least one first detector device;
• and
• (d) at least one processor device for processing and comparing (i) said first data, (ii) said second data, said third data, and (iii) said fourth data, to stored values to determine potential presence of at least one neurological disorder in the subject.
