Clinical study on Jin’s three-needle therapy for post-stroke cognitive impairment

Abstract

To observe the clinical efficacy of Jin’s three-needle therapy on post-stroke cognitive impairment (PSCI) and the effect on neuroelectrophysiology (event-related potentials). A total of 60 PSCI patients were selected and divided into a treatment group and a control group according to the method of random number table, with 30 cases in each group. The patients in the control group received routine treatment while the patients in the treatment group received additional Jin’s three-needle therapy. The treatment for both groups lasted four weeks. Mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) scores as well as amplitude and latency of potential 300 (P300) were adopted to compare the between-group results before and after treatment. Before treatment, there were no significant differences (all P>0.05) in MMSE and MoCA scores, P300 latency and P300 amplitude between the two groups. After 4 weeks of treatment, the MMSE and MoCA scores and P300 amplitudes were improved in both groups, and the P300 latencies became shorter. The results showed significant intra-group and between-group differences (all P<0.05). Based on the routine treatment, Jin’s three-needle therapy is effective for PSCI. The mechanism is probably through its regulation on the patients’ neuroelectrophysiology.
