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], Although the 10-MWT[sup] and the 6-MWT[sup] 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] as observed in this study.
sup] 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], as well as to assess disease severity in cross-sectional studies.
