PMID 36467522WHAT IT FOUND
Normative data for the O'Connor Finger Dexterity Test in Macau office workers showed no significant differences by age, sex, or typing hours.
However, the sample size was too small to generate reliable norms, so these values should be used with caution.
Key findings
01There was no significant difference in finger dexterity scores between the three age groups.
02Finger dexterity scores did not differ significantly based on the number of hours spent typing, writing, or filing.
03The study authors state that the sample size of 127 is insufficient to generate reliable normative scores.

What it does not show
The sample size of 127 is considered too small to generate reliable normative scores. Participants were recruited via convenience sampling from specific institutions, which limits generalizability. The study only included right-handed participants, so results may not apply to left-handed individuals. No comparison was made between the dexterity test results and other functional assessments.
Declared interests
None reported.
The easy way to misread this
Do not treat these percentile scores as established normative data. The authors explicitly state that the sample size of 127 is insufficient to generate reliable norms, so using these values to diagnose impairment or evaluate progress may lead to incorrect conclusions.
