BACKGROUND AND PURPOSE: To investigate the test-retest reliability, the standard error of measurement (SEM), and the smallest real difference (SRD) of the finger to nose test, as well as establish its reference values, according to sex, age, and dominant limb.
METHODS: Individuals were requested to touch a 6 cm target, fixed in front of them, as quickly as possible for 20 s, first with the dominant limb and then with the non-dominant limb. In order to assess test-retest reliability, the test was administered two times, in 30 individuals, 5-7 days apart. In order to establish the Finger to Nose reference values, at least 30 individuals (15 women and 15 men) in each follow age group were collected: 20-29, 30-39, 40-49, 50-59 and over 60 years old. Test-retest reliability was assessed using the intraclass correlation coefficient (ICC). The SEM and SRD were calculated from the ICC.
RESULTS: One hundred and sixty-five individuals were assessed. The test-retest reliability of the Finger to Nose showed good values, with an ICC of 0.92 for the dominant limb and 0.86 for the non-dominant limb. The SEM values were < 15%, being 9% for the dominant limb and 11% for the non-dominant limb, and were also considered adequate. Regarding the SRD, the values found were 7 points for the dominant limb and 8 points for the non-dominant limb. Finally, reference values were established based on sex, age and limb dominance.
DISCUSSION: This study showed that the Finger to Nose test has good reliability for assessing upper limb motor coordination. In addition, changes of at least 7 points in the dominant limb and 8 in the non-dominant limb are necessary to be considered clinical changes in the patient. Finally, reference values were defined based on sex, age and dominance, offering support for future assessments and interventions.
