Tongue Acupuncture to Treat Dysphagia in Patients with Parkinson's Disease: A Randomized Controlled Trial.

OBJECTIVE

Parkinson's disease (PD) is a chronic degenerative disease that lacks specific treatment. The incidence of dysphagia in patients with PD is 35%-82%. Dysphagia not only affects nutritional intake but also leads to pneumonia, even asphyxia. This study explored the efficacy of tongue acupuncture for treating dysphagia in patients with PD.

MATERIALS AND

METHODS

From March 2021 to June 2023, 64 patients with PD-related dysphagia were chosen from Qingdao Central Hospital and the Affiliated Hospital of Qingdao Binhai University, both in Qindao, Shandong, China. The patients were divided into a tongue acupuncture group (n = 32) and a control group (n = 32). The control group was treated with a VitalStim® 5900 Swallowing Disorder Therapeutic Instrument (CA, USA), and the tongue acupuncture group had tongue acupuncture at Juquan (Ex-HN-10) and Haiquan (Ex-HN-11). Swallowing function and nutritional conditions were compared between the 2 groups after all treatments.

RESULTS

The total clinical effective rate in the tongue acupuncture group was higher than that of the control group (P < 0.05). The proportion of grade 1 and grade 2 of the 5-scaled Kubota drinking-water test in the tongue acupuncture group was significantly higher than that in the control group (78.13 % versus 31.26 %; P < 0.05), and the proportion of grade 3, grade 4, and grade 5 was significantly lower than that in the control group (21.87 % versus 68.74 %; P < 0.05). After tongue acupuncture, levels of body mass index, upper-arm circumference, triceps skinfold thickness, hemoglobin, serum albumin, and prealbumin were significantly higher than those in the control group (P < 0.05) and the incidence of complications caused by PD was significantly lower than that in the control group (P < 0.05).

CONCLUSIONS

Treatment of dysphagia in PD by tongue acupuncture significantly improved swallowing function and nutritional level, and decreased the incidence of complications.
