Abstract:

Objective To investigate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) combined with bilateral arm training (BAT) on upper limb motor function of hemiplegic stroke patients.

Methods From January, 2021 to January, 2022,105 stroke patients from Zhejiang Provincial People's Hospital were randomly divided into taVNS group (n = 35), BAT group (n = 35) and combined group (n = 35). All the patients received routine rehabilitation, while taVNS group received taVNS, BAT group received BAT, and the combined group received both taVNS and BAT, for eight weeks. The root mean square (RMS) of surface electromyography in deltoid, triceps brachii and extensor carpi was measured, and the scores of Box and Block Test (BBT), and Fugl-Meyer Assessment-Upper Extremities (FMA-UE) were obtained before and after treatment.

Results The RMS of all these muscles, and the scores of BBT and FMA-UE improved in all the three groups after treatment (|t| > 6.124, P< 0.001), and they were improved the most in the combined group (F > 18.162, P< 0.001).

Conclusion Both taVNS and BAT can enhance the muscle strength on the affected upper limb, increase the hand flexibility, and improve upper limb motor function of stroke patients, while the combination of both methods is more effective.
