Abstract:
Objective To investigate the combined effects of digastric muscle low frequency modulated medium frequency electro-acupuncture therapy and voice training for dysphagia in patients who underwent aortic arch surgery. Methods Forty-two consecutive patients with dysphagia after aortic arch surgery between October 2014 and November 2017 were divided into two groups including an observation group and a control group. There were 21 patients in each group. There were 17 males and 4 females at age of 51.0±6.5 years in the observation group, while 18 males and 3 females at age of 49.8±7.3 years in the control group. The patients in the observation group underwent electroacupuncture therapy and voice training (20 min per day for each therapy, 2 weeks), while the patients in the control group only received safe swallowing education and rehabilitation guidance (2 weeks). The test results, such as fibrolaryngoscope and functional
oral intake scale (FOIS) score, and the data of computer phonatory detection, before and after the intervention were compared. Results The fibrolaryngoscope of vocal cords significantly decreased and the FOIS score significantly increased after digastric muscle low frequency modulated medium frequency electro-acupuncture therapy and voice training in the observation group(6.30 vs. 4.60, P<0.05). Bucking was obviously reduced. The indicators of hoarse degree, such as median pitch, fundamental frequency, jitter (0.60%±0.96% vs. 1.99%±1.86%, P=0.033), shimmer (2.47%±4.26% vs. 5.89%±3.66%, P=0.043), maximum phonation time (15.31±9.10 s vs. 3.72±8.83 s, P=0.006), maximum and loud phonation time (9.30±5.73 s vs. 2.32±2.99 s, P=0.039), mean noise-to-harmonics ratio (23.99±10.17 vs .9.98±9.37, P=0.006) and mean harmonics-to-noise ratio (0.03±0.02 vs. 0.17±0.23, P=0.019) improved after the treatment in both groups. But the improvement in the observation group was significantly better than that in the control group. Conclusion The combination of digastric muscle low frequency modulated medium frequency electro-acupuncture therapy and voice training on dysphagia in patients who underwent aortic arch surgery can significantly improve the swallowing function of patients. Meanwhile, it also helps the recovery of phonic function and improves the ability of feeding and communication in these patients.
