Limitations of the study
There were some limitations of this study including the lack
of patient and therapist blinding. However, it is because of
the nature of treatments which make it difficult to conduct.
In addition, this study is limited by the lack of a control group
since ethical reasons do not allow non-treatment of the
patients. Future studies may use the resting condition (The
participant relaxed by lying on their side quietly in the same
environment as the treatment group) with education as
a control group to solve this limitation.
