Abstract:

Objective To explore the effect of anodal transcranial direct current stimulation (atDCS) on premotor cortex (PMC) on upper limb motor function in patients with severe stroke.

Methods From June, 2021 to December, 2022, 60 patients with severe stroke in Zhejiang Provincial People's Hospital were randomly divided into control group (n = 20), primary motor cortex (M1) group (n = 20) and PMC group (n = 20). All the groups accepted routine rehabilitation treatment, while the control group accepted atDCS pseudo stimulation to the focus side PMC, M1 group accepted atDCS to the focus side M1, and PMC group accepted atDCS to the focus side PMC, for six weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), the surface electromyography root mean square (RMS) ratio of affected/unaffected side of triceps and extensor carpus were used to evaluate the efficacy before and after treatment.

Results After treatment, the scores of FMA-UE and WMFT, and RMS ratio of triceps and extensor carpus significantly increased in all the groups (|t| > 2.458, P < 0.05), and were better in PMC group than in the other two groups (F > 4.084, P< 0.05).

Conclusion atDCS on PMC could improve the overall function of upper limb in patients with severe stroke.
