Low frequency-repetitive transcranial magnetic stimulation combined with Xingnao Kaiqiao acupuncture improves post-stroke cognitive impairment and has better clinical efficacy.

BACKGROUND

Enhancing post-stroke cognitive impairment (PSCI) is a key aspect of prognosis for stroke patients. Low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) is currently a widely utilised method for treating PSCI. With the increasing promotion of traditional Chinese medicine, Xingnao Kaiqiao (XNKQ) acupuncture has been progressively incorporated into clinical treatment. This paper observes the effect of LF-rTMS with XNKQ acupuncture on patients with PSCI.

METHODS

Totally, 192 patients with PSCI were consecutively recruited and treated either with LF-rTMS and XNKQ acupuncture (observation group) or LF-rTMS only (control group) for 4 weeks. The pre- and post-treatment Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores, P300 latency and amplitude, inflammatory factor levels were compared and clinical efficacy was assessed.

RESULTS

Both groups exhibited increased MMSE/MoCA scores, and P300 amplitude, and shortened P300 latency, and the observation group had higher scores and P300 amplitude, and shorter P300 latency than the control group. Both groups displayed decreased inflammatory factor levels (Tumour necrosis factor-α, interleukin (IL)-6, IL-10, IL-1β) after treatment, which were lower in the observation group than the control group. Inflammatory factor levels in PSCI patients were negatively interrelated with MMSE, MoCA score and P300 amplitude, and positively with P300 latency. The observation group showed an increased number of patients showing cured and significantly effective results, a decreased number of patients showing effective and invalid results, and an observably elevated total effective rate.

CONCLUSION

LF-rTMS with XNKQ acupuncture can improve cognitive function and reduce inflammatory immune response, and has better clinical efficacy in PSCI patients.
