The study showed that combining liuzijue qigong with basic articulation training can significantly improve the respiratory control and comprehensive speech ability of stroke patients with dysarthria.
Objective: The aim of the study was to investigate whether liuzijue qigong could improve the ability of respiratory control and comprehensive speech in patients with stroke dysarthria. Design: A randomized controlled trial. Setting: The research was carried out in the department of rehabilitation. Participants: Altogether, a total of 98 stroke patients with dysarthria participated in the study. Interventions: Patients were randomly divided into two groups (the experimental group: basic articulation + liuzijue qigong, 48 patients or the control group: basic articulation + traditional breathing training, 50 patients). All therapies were conducted once a day, five times a week for three weeks. Main measures: Primary outcome measure: Speech breathing level of the modified Frenchay Dysarthria Assessment. Secondary outcome measures: the modified Frenchay Dysarthria Assessment, maximum phonation time, maximal counting ability, /s/, /z/, s/z ratio, and the loudness level. All outcome measures were assessed twice (at baseline and after three weeks). Results: At three weeks, There were significant difference between the two groups in the change of speech breathing level (81% vs 66%, P = 0.011), the modified Frenchay Dysarthria Assessment (5.54 (4.68-6.40) vs 3.66 (2.92-4.40), P = 0.001), maximum phonation time (5.55 (4.92-6.18) vs 3.01(2.31-3.71), P < 0.01), maximal counting ability (3.08(2.45-3.71) vs 2.10 (1.53-2.67), P = 0.018), and /s/ (3.08 (2.39-3.78) vs 1.87 (1.23-2.51), P = 0.004), while no significant differences were found in the change of /z/ (3.08 (2.31-3.86) vs 2.10 (1.5-2.64), P = 0.08), s/z ratio (1.26 (0.96-1.55) vs 1.03 (0.97-1.09), P = 0.714), and the change of loudness level (69% vs 60%, P = 0.562). Conclusions: Liuzijue qigong, combined with basic articulation training, could improve the respiratory control ability, as well as the comprehensive speech ability of stroke patients with dysarthria.
