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.

How much administration time is required?

The time required is 5 minutes.

How to calculate the score?

The score is computed for each hand separately and is the time required to place the pegs. Some researchers also record the number of pegs not placed and the number of pegs dropped; these errors may be considered clinically and are rarely seen in neurologically normal individuals.

Demographic Effect

Age

• Age has a strong impact on test scores, with performance improving (faster times) in childhood and declining with advancing age (e.g., Bornstein, 1985; Concha et al., 1995; Mitrushina et al., 2005; Ruff & Parker, 1993; Selnes et al., 1991).
• According to Heaton et al. (2004), about 30 degrees to 31 degrees of the variance in test scores is accounted for by age.

Gender

• Some have found significant gender differences in performance, with women outperforming men (Bornstein, 1985; Ruff & Parker, 1993; Schmidt et al., 2000), perhaps reflecting differences in finger size (Peters et al., 1990).
• However, others have noted that gender has little effect on test scores (Concha et al., 1995; Heaton et al., 2004; Mitrushina et al., 2005), accounting for less than 1% of the variance in test scores (Heaton et al., 2004).
• No gender effect has been found in children (Rosselli et al., 2001).

Hand Preference

• Performance is faster with the dominant/preferred hand (Bryden et al., 1998; Heaton et al., 2004). Handedness (right, left) does not affect test scores (Ruff & Parker, 1993).
