Nine Hole Peg test (NHP)

Description:

The Nine Hole Peg Test is regularly used by therapists as a simple and rapid evaluation of dexterity [9].

The patient sits in front of a table and with one hand must place 9 pegs (9 mm in diameter and 32 mm long) in a wooden box containing 9 holes (10 mm in diameter and 15 mm deep).

The time required to perform this task is recorded, or if it is greater than 50 seconds, the number of pins placed is recorded.

The normal is 18 seconds for 9 pins. The unevaluated hand can be used to hold the frame, but not to place pins.

In general, this test can only be used for people with moderate partial deficits. It is not indicated in the initial phase of recovery from severe CNS lesions.

The purchase price of new equipment is between 100 and 150 Euros.

Performing the test takes less than 10 minutes, and no special training is required for the evaluator.

While the majority of studies are conducted in patients with vascular disease, 2 studies were conducted on multiple sclerosis patients [8, 14].

General comment on reliability:

This is the only grip test with three psychometric criteria (inter judge reproducibility, validity and test -retest convergence/Concurrence) [10].
Internal consistency is high [14].
Excellent convergent validity with the Motricity Index [4].
Very good inter-judge reproducibility [9, 14], and moderate correlation [ 9] good [ 12, 14 ] between the scores of the subjects (test-retest).
The MDC (Minimal Change Detection, which is a statistical estimate of the smallest amount of change that can be detected by measuring, and representing a significant change) is high on the most affected side (32.8 s) [12].
It can detect an improvement in distance after patients have achieved a maximum score in the Frenchay Arm Test [5].
BBT and ARAT seem more appropriate for evaluating dexterity than the Nine Hole Peg Test but the sensitivity to change, which is moderate [1], is the same between the three tests. [13]
