. The mean age of the patients included in the study was 79.18 ± 8.67 years,
with patients with severe cognitive decline being the oldest on average (84, 60
± 2.61), followed by patients with mild cognitive decline (79, 47 ± 8.75) and pa-
tients with moderate cognitive decline (76.50 ± 9.52).

The results of the descriptive statistics and the difference between the first
and second DEMMI tests in all three groups and Wilcoxon signed-ranked test
are shown in Table 2. In the first assessments, the patients with mild cogni-
tive impairment achieved on average the highest scores (51.47 ± 22.53 points),
followed by the patients with moderate cognitive impairment (49.50 ± 19.22
points). On average, patients with severe cognitive decline (45.80 ± 23.91 points)
achieved the lowest scores in the first assessment.

The results of the second DEMMI test improved in all three groups. The
greatest improvement was seen in the group with mild cognitive decline. On
the other hand, the smallest improvement was observed in the group with se-
vere cognitive decline. The SD of DEMMI test scores in both first and second
tests do not exceed 25 % of the M, indicating small differences in mobility with-
in each group.
The results of Wilcoxon signed-ranked test showed statistically signifi-
cant differences between the results of the first and the second DEMMI test in
with patients with severe cognitive decline being the oldest on average (84, 60
± 2.61), followed by patients with mild cognitive decline (79, 47 ± 8.75) and pa-
tients with moderate cognitive decline (76.50 ± 9.52).
