[57] ABSTRACT
An apparatus (10) for testing the sensory system in humans or animals comprising housing parts (12, 14) which are jointed together in volume defining manner to form a housing. The housing has a gap formed by recesses (64,66) in the housing parts, and encloses a disc (26) having mounted thereon a plurality of pins (40) with tips extending beyond the periphery of the disc (26). The pins (40) are held captive in the housing and cannot be removed therefrom. The disc (26) is arranged to be rotated incrementally by a manually operable knob (30) so as to present the pins (26) in sequence to the gap.
