On psychological assessment, the levels of
anxiety and depression in Group 6 were found
to be higher than those of other groups, suggesting
that subjective symptoms are associated
with psychological distress. Although LE and
depression are associated, the depression
levels of patients in Group 5 with prominent
LE were lower than those of patients in Groups
1 and 6, which means that the associated factors
of depression are multiple,and more active
pain control is indicated for the patients
with depression.
