Sialorrhea (saliva production perceived by patient as excessive) is one of the non-motor manifestations of Parkinson’s disease (PD) mostly found at late stages of the disease. In one study, 46, 5% of patients with PD who complained about drooling also suffered swallowing problems of which 18, 8% thought that it was socially disabling. The present study was mainly designed to evaluate the effectiveness of an alternative non-invasive management approach involving speech therapy for individuals with sialorrhea as a consequence of PD. For this purpose, we evaluated the effectiveness of 2 approaches to reduce sialorrhea, Thermal-Tactile Stimulation (TTS) and Cognitive Behavioral Treatment (CBT)
Methodology: For this prospective cohort study, 18 individuals with PD were recruited and divided randomly into two groups. The first one received only CBT while the other received CBT plus TTS. The saliva produced by the individuals during 5 minutes after the stimulation session ended was collected using graduated tubes that were weighed. We also evaluated the perception of sialorrhea using the Clinical Scale of Sialorrhea for Parkinson’s (SCS-PD). Both types of measurement were made at the beginning of the study and after 5 weeks of therapy. A T-student parameter test and the Mann-Whitney test were used to compare results.
Results: The difference observed in the measurement of saliva secretion before and after treatment in both groups was not statistically significant (Fig. 1). Neither was the difference on the scores of the SCS-PD between the CBT group and CBT plus TTS group. However, there was a statistically significant decrease in the scores comparing baseline and end line measurements in both groups (p<0.001).
Conclusions: Both treatments are effective to decrease sialorrhea perception with no significant differences between both types of treatments. An alternative non-invasive approach may be suggested to individuals who suffers sialorrhea secondary to PD.
