Objectives: This study investigated the effect of electroacupuncture on swallow function in stroke patients with dysphagia. The purpose was to determine whether electroacupuncture could improve swallow function and quality of life for patients with dysphagia caused by stroke. A pilot double-blind, randomized controlled trial design was used.
Methods: A total of 17 stroke patients with dysphagia were recruited to this study, 8 assigned to the swallowing electroacupuncture (SE) group and 9 to the control group. Swallowing electroacupuncture was assessed for 5 Hz electrical or sham stimulation for 20 min duration 3 times a week. Outcome measurements were DOSS, 14-item questionnaire from the SWAL-QOL, NIHSS and MBI. Assessment was carried out for baseline, 2 weeks and 4 weeks.
Results: In the 2 weeks follow up data, the study group showed significant difference in DOSS and SWAL-QOL compared with the baseline. The study group also showed significant difference in DOSS and SWAL-QOL compared with the control group. Similarly in the 4 weeks follow up data, the study group showed improvement tendency in DOSS and SWAL-QOL compared with baseline and also with the control. The NIHSS and MBI scores returned no significant differences. The swallowing electroacupuncture was well tolerated in all cases with no serious adverse effects.
Conclusions: The findings from the pilot study indicated that electroacupuncture has significant effects on improvement in swallowing function and quality of life. With both inpatients and outpatients, further larger and longer-term follow-up study is needed to confirm this suggestion.
