Correlation Between the 'Nine Holes Peg Test' Performance and the Triple Stimulation Technique Within a Group a Patients With Multiple Sclerosis

The Nine Hole Pegs technique is a simple manual dexterity test, commonly used in ergotherapy. The participant tries to place 9 pegs in a 9 holes perforated plate, and then tries to remove them as quickly as possible. The hand must stay in a depression within the plate, thereby insuring a constant distance between the hand and the pegs.

TST (Triple stimulation technique) combines two techniques used in neurologic diagnosis: magnetic stimulation and electroneuromyography. It is based on the principle of two collisions between the descending central stimulation (magnetic stimulation) and the ascending peripheric stimulation. TST allows to better quantify central nervous system diseases. The abnormal amplitude registered by TST is proportional to the intensity of conduction disorders. The evaluation of these disorders is more precise than with the magnetic stimulation technique alone.
