First, the occupational therapists in the two groups were not completely blinded to the nature of the intervention. Sec- ond, our findings were based on a relatively small number of patients, all of whom were women. Third, so far no follow-up study has been conducted to corroborate the findings. A future follow-up study should include a larger sample and should include men as well. Moreover, this study only evaluated tasks performed by patients in the intervention group.
