Clinical Trial Summary

Up to 84% of patients after stroke are accompanied by dysphagia, of which 53% are oral dysphagia. The oral phase is the initial phase of swallowing activity and the only stage of swallowing that is completely discretionary. Swallowing activity in the oral stage is not only related to the formation and push of food pellets, but also affects the continuity between the transition from spontaneous swallowing to the swallowing reflex.

Description:

After stroke, patients are prone to oral dysphagia, poor control of food masses and liquids in the mouth, resulting in food spillover, residual and premature overflow, resulting in dehydration, malnutrition, aspiration, pneumonia and other serious consequences, which greatly reduce the eating safety and quality of life of patients after stroke. Therefore, the rehabilitation of oral swallowing function is a way for patients with swallowing disorder after stroke to return to society and improve their quality of life. Previous studies have found that acupuncture is an effective intervention to improve swallowing disorder in oral stage after stroke. Whether acupuncture promotes the improvement of swallowing function in oral stage by regulating the synergic activity of cortical swallowing network and muscle group has not been fully clarified.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Oral functional score	To assess participants' oral swallowing function	4 weeks (Before and after intervation)
Secondary	Surface electromyography	To assess the swallowing muscle activity	4 weeks (Before and after intervation)
Secondary	Water swallowing test (WST)	The severity of dysphagia was assessed by the WST. Level 1: Can drink 30ml water successfully within 5 seconds; Level 2: Drink water more than 2 times, can swallow without choking. Level 3: Can be drunk once, but cough. Level 4: swallowed more than twice, but with choking. Level 5: Frequent choking, unable to swallow all. Normal: Level 1, Suspicious: Level 1, more than 5 seconds or level 2; Abnormal: Level 3 to 5	4 weeks (Before and after intervation)
Secondary	Standardized Swallowing Assessment (SSA)	To assess the severity of swallowing. The lowest score on this scale is 18 points, the highest score is 46 points, the higher the score, the worse the swallowing function.	4 weeks (Before and after intervation)
Secondary	Functional Oral Intake Scale (FOIS)	To assess the condition of swallowing. The grade of FOIS was categorized as level 1 to 3 (poor FOIS: tube feeding), levels 4 and 5 (moderate FOIS: total oral diet requiring special preparation) or levels 6 and 7 (good FOIS: total oral diet without special preparation).	4 weeks (Before and after intervation)
Secondary	Teacher salivation rating (TDS)	Assess salivation. Level 1: No salivation; Level 2: Small amount, occasional flow. Level 3: Stream from time to time; Level 4: Flow frequently, but not linearly; Level 5: Flow in line, chest often wet	4 weeks (Before and after intervation)
Secondary	Swallowing Related Daily Quality of Life Scale (SWAL-QOL)	Assessed patients' quality of life. The SWAL-QOL scale consists of 11 dimensions, covering 44 items, of which 10 dimensions measure patients' quality of life and one dimension measures patients' swallowing symptoms. The 10 quality of life dimensions included 30 items, of which 8 (25 items in total) were related to swallowing, including psychological burden, eating time, appetite, food choice, verbal communication, fear of eating, mental health, and social interaction: the common dimension had 2 (5 items in total), including fatigue and sleep. The dimension of swallowing symptoms included 14 items. The SWAL-OOL scale was scored by Likert scoring method. The higher the score of five levels (1-5 respectively), the better the quality of life.	4 weeks (Before and after intervation)
