How to use Lafayette Grooved Pegboard?
Pegboard administration instructions:
- The apparatus is placed with the peg tray oriented above the pegboard.
- The person is instructed to insert the pegs, matching the groove of the peg with the groove of the hole, filling the rows in a given direction as quickly as possible, without skipping any slots.
- Using the right hand, the patient is asked to work from left to right, and with the left hand, in the opposite direction.
- The dominant hand is tested first. The patient is warned that only one peg should be picked up at a time and that only one hand is to be used.
- If a peg is dropped, the examiner does not retrieve it; rather, one of the pegs correctly placed (usually, the first or second peg) is taken out and used again.
- The examiner demonstrates one row before allowing the patient to begin. A practice trial is not given, and a trial may be discontinued after 5 min.
- In the HRNES (Russell and Starkey, 1993) version, the person continues until all pegs have been placed or until a time limit of 3 min has been reached.
- ln both versions, the examiner begins timing after cueing the individual to begin.
