In this study, we compared the responsiveness and validity of the Box and Block
Test (BBT), the Nine-Hole Peg Test (NHPT), and the Action Research Arm Test
(ARAT). We randomized 59 patients with stroke into one of three rehabilitation
treatments for 3 weeks. We administered six outcome measures (BBT, NHPT, ARAT,
Fugl-Meyer Assessment [FMA], Motor Activity Log [MAL], and Stroke Impact Scale
[SIS] hand function domain) pretreatment and posttreatment. We used the
standardized response mean (SRM) to examine responsiveness and the Spearman rank
correlation coefficient (rho) to examine concurrent validity. The BBT, NHPT, and
ARAT were moderately responsive to change and not significantly different (SRM =
0.64-0.79). The correlations within the BBT, NHPT, and ARAT were moderate to good
at pretreatment (rho = -0.55 to -0.80) and posttreatment (rho = -0.57 to -0.71).
The BBT and ARAT showed fair to moderate correlations with the FMA, MAL, and SIS
hand function domain at pretreatment and posttreatment (rho = 0.31-0.59), whereas
the NHPT demonstrated low to fair correlations with the FMA and MAL (rho = -0.16
to -0.33) and moderate correlations with the SIS hand function domain (rho =
-0.58 to -0.66). Our results indicate that the BBT, NHPT, and ARAT are suitable
to detect changes over time. While simultaneously considering the responsiveness
and validity attributes, the BBT and ARAT can be considered more appropriate for
evaluating dexterous function than the NHPT. Further studies with larger samples
are needed to validate these findings.
