Because specific evidence for occupational therapy in
PD is lacking, some insights might be gained from
evidence obtained with other chronic disorders in which
functional problems bear resemblance to PD. We will
discuss occupational therapy interventions that appeared to
have some potential for improving activities and participation
in PD. The level of evidence has been adjusted
accordingly when evidence was obtained from related areas
or disciplines other than occupational therapy itself. For
example, although there is Level 2 evidence for using
cues to improve gait, the strength of the recommendation
for occupational therapy is weaker as limited evidence is
available for its effectiveness in improving the performance
of functional activities
