9-HPT

A timed performance test in which a subject places nine dowels in nine holes and then removes them, first with the dominant hand and then with the nondominant one. The more rapidly the test is performed, the greater the dexterity of the subject.

Results: The mean 9-HPT completion time in the dominant hand of CMT patients was significantly slower than that in the healthy controls (29.
sup][17],[18] Although the 10-MWT[sup][19] and the 6-MWT[sup][20] were previously used in China, 9-HPT and 10-MWT are not widely used in patients with CMT.
All control subjects were assessed using 9-HPT and 10-MWT, and all patients underwent a standardized protocol that included the following evaluations:
The dominant hand completed 9-HPT faster than the nondominant hand (CMT group: t = −2.
There was a positive correlation of 9-HPT completion time with ONLS and FDS, and a negative correlated with BBS just for CMT patients.
003), but no correlation with 9-HPT completion time (dominant hand: r = 0.
Further, reduced thumb mobility and intrinsic finger function in CMT patients limited prehension, resulting in abnormal posture during the 9-HPT test.
The 9-HPT is a standardized, ratio scale tool with established norms, and is available and portable for use in a variety of settings, including the clinic, laboratory, and home.
There is some evidence that 9-HPT completion time is shorter in women than that in men,[sup][34] as observed in this study.
sup][37] reported a positive correlation of the 9-HPT completion time in children with CMT with the ONLS score ( r = 0.
Several studies have shown that 9-HPT and 10-MWT could be used to determine changes in the clinical function of patients,[sup][5],[38] as well as to assess disease severity in cross-sectional studies.
