Study of electroacupuncture with different frequencies for the treatment of headache and anxiety-depression symptoms in patients with migraine: A randomized clinical trial: 不同频率电针改善偏头痛患者头痛及焦虑抑郁症状的差异性研究-随机临床试验

ObjectiveTo observe the effects of electroacupuncture (EA) with varied frequencies on headache and anxiety-depression symptoms in patients with migraine and to screen optimal frequency of EA for patients with such conditions.DesignSingle-center, randomized, controlled clinical trial was designed, and the outcome assessors and statisticians were blinded. The patients with migraine were randomized into 2 Hz EA group, 100 Hz EA group and sham-stimulation group. In each group, the changes in migraine attacks, days with headache, the scores of visual analogy scale (VAS), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and migraine-specific quality-of-life questionnaire (MSQ), as well as the dosage of analgesics were observed at the baseline, during treatment, in 1, 2 and 3 months of follow-up separately.SettingPatients were enrolled in the Third Affiliated Hospital of Zhejiang Chinese Medical University, between 1^st August 2018 and 31^st July 2021.ParticipantsSixty-five migraine patients with or without aura.InterventionsIn the EA groups, the acupoints were bilateral Fengchi (GB20), Gongxue (Extra), Sizhukong (TE23), Taiyang (EX-HN5), Shuaigu (GB8), Waiguan (TE5) and Yanglingquan (GB34). Electric stimulation was exerted at GB20 and Gongxue (Extra), with 2 Hz and 100 Hz separately. In the sham-stimulation group, the shallow acupuncture was operated at the sites 1 cm lateral to GB20 and Gongxue (Extra), and on the radial side of TE5 and GB34. The output wires were cut off after attached to the acupoints. The patients in each group received the treatment 3 times weekly, once every two days, for consecutive 4 weeks. The complete intervention was composed of 12 treatments.Main outcome measuresChanges in numbers of migraine attacks at treatment phase (week 1 to week 4) from the baseline(week -4 to week 0) in patients of each groupResults(1) Changes in migraine attacks and days with headache: In the 2 Hz EA and 100 Hz EA groups, the changes for migraine attacks and days of headache were higher significantly when compared with that in the sham-stimulation group at the same time stage (P < 0.05). There was no statistical difference between two EA groups. (2) Changes of VAS score: In the 2 Hz EA and 100 Hz EA groups, the changes of VAS score were significantly higher when compared with that in the sham-stimulation group at the same time stage (P < 0.05). There was no statistical difference between two EA groups. (3) Assessment of anxiety and depression: The differences in the changes of SAS and SDS scores had no statistical significance in patients of each group at each assessment stage (P > 0.05). (4) Assessment on the quality of life: Compared with the sham-stimulation group at the same time stage, the improvement in MSQ score was increased significantly during treatment in patients of the 2 Hz EA and 100 Hz groups (P < 0.05). There was no statistical difference between two EA groups. (5) Assessment on safety and compliance: The patients of each group had sound compliance. There was no adverse events during trial, suggesting promising safety of treatment.ConclusionEA may effectively reduce the migraine attacks, and the days and intensity of headache, presenting promising safety. However, there was no significant improvement on anxiety-depression symptoms, and no significant difference between high and low frequencies of EA treatment in relieving headache and anxiety/depression symptoms in the patients with migraine.Trial registrationChiCTR1800017259

ObjectiveTo observe the clinical efficacy of different acupuncture modalities in the treatment of adhesive capsulitis a tthrough different clinical stages.MethodsNinety patients of adhesive capsulitis weregraded in three different stages based on clinical presentations. Patients in painful stage were treated with silver needles once every 5to 7 days for two courses; patients in adhesive stage were given acupotomy treatment every 7 to 10 days for two courses; while patients in recovery stage were treated with acupuncture with warm needles by moxibustion on tendon knots, once a day 10 times in a course, for two courses of treatment. The disease scores were compared between all groups before and after the treatment, and clinical efficacy was evaluated after the treatment.ResultsThe disease scores in patients of all three stages were higher after treatment, and the differences were statistically significant (all P < 0.05). Among 90 patients with adhesive capsulitis, 32 cases were clinically under controlled, 37 cases claimed remarkably effective, 18 were effective, and 3 ineffective cases, thus the total effective rate for this stage-based treatment is 96.7%.ConclusionFor adhesive capsulitis,different acupuncture modalities targeting patients in different clinical stages were feasible and effective, the disease scores of patients were significantly improved.

电针联合骨质疏松治疗仪对脊髓损伤患者骨代谢指标的影响

ObjectiveTo observe the effect of electroacupuncture combined with low-frequency pulsed electromagnetic field on bone metabolism in patients with spinal cord injury (SCI).MethodsThe 60 SCI patients who met the inclusion criteria were randomly divided into 2 groups by means of a random number table. In the control group, 30 patients were treated with osteoporosis treatment apparatus. In the observation group, 30 patients were treated with osteoporosis treatment apparatus and electroacupuncture at the foot-shaoyangacupoints [Yánglíngquán (阳陵泉GB 34) and Xuánzhōng (悬钟GB 39) of both sides].The treatment was applied once a day, 5 days a week, for 8 weeks.Before and after treatment, the changes of indexes in the two groups, including the bone mineral density (BMD), bone gla-containing protein (BGP), serum alkaline phosphatase (ALP), procollagen type I C-peptide (PICP), and 25‑hydroxy-vitamin D [25(OH)D], were observed for comparison.ResultsAfter treatment, in the two groups, the BMD and 25(OH)D indexes of the femoral neck, greater trochanter, and Ward's triangle region were not significantly changed in comparing with those before treatment (P>0.05), while the BGP, ALP, and PICP indexes were significantly higher than those before treatment (P<0.05). After treatment, in the observation group, the BGP and ALP indexes were significantly increased in comparing with those of the control group, and the difference was statistically significant (P<0.05), whilst the BMD, PICP, and 25(OH)D indexes of the femoral neck, greater trochanter, and wards triangle region, were not significantly different in comparing with the control group (P>0.05).ConclusionThe osteoporosis treatment apparatus can improve bone metabolism in SCI patients, and the curative effect can be enhanced when combined with electroacupuncture at foot-shaoyangacupoints.
