Laser acupuncture and photobiomodulation therapy in Bell's palsy with a duration of greater than 8 weeks: a randomized controlled trial.

To investigate the efficacy of laser acupuncture and photobiomodulation therapy in alleviating symptoms among patients diagnosed with Bell's palsy with duration of greater than 8 weeks. The randomized controlled trial has been performed from May 2021 to April 2023. Patients were eligible who had Bell's palsy with duration of greater than 8 weeks on out-patient Department of Otorhinolaryngology in Beijing Tongren Hospital. The laser acupuncture group received class IV laser treatment for 3 times per weeks, a total of 72 times. The control group received the same treatment procedure except the laser parameter. The primary outcome measures comprised House-Brackmann facial nerve grading system and electroneurography. Secondary outcome measures comprised Sunnybrook facial grading system, electromyography, and the blink reflex. A total of 84 participants were included (42 control group, 42 laser acupuncture group). After treatment, House-Brackmann facial nerve grading system (OR, 0.11; 95% CI, 0.04-0.30; P < 0.001), and the pathologic numbers of electroneuronography were statistically different between the laser acupuncture group and control group, including orbicularis oculi (OR,0.08; 95% CI, 0.02-0.21; P < 0.001), Frontalis muscle (OR,0.14; 95% CI, 0.05-0.39; P < 0.001), Orbicularis oris (OR,0.13; 95% CI, 0.04-0.36; P < 0.001), Ala nasi muscle (OR,0.06; 95% CI, 0.02-0.18; P < 0.001). In secondary outcomes, Sunnybrook facial grading system, has significant difference between the two groups (20.26; 95% CI, 14.69 to 25.83; P < 0.01). Latency by ENoG, include orbicularis oculi (-0.61; 95% CI, -0.43 to -0.09; P < 0.001), frontalis muscle (-0.12; 95% CI, -0.21 to -0.03; P < 0.01), orbicularis oris (-0.28; 95% CI, -0.41 to -0.16; P < 0.001), and ala nasi muscle (-0.26; 95% CI, -0.38 to -0.16; P < 0.001). All amplitudes of MUAPs and durations by electromyography (EMG) showed statistically significant differences compared with the control group after treatment. For the frontalis muscle, the amplitude of MUAPs was -64.23 (95% CI, -80.89 to -47.56; P < 0.001) and duration was -1.18 (95% CI, -1.49 to -0.87; P < 0.001). For orbicularis oris, amplitude of MUAPs was -29.82 (95% CI, -55.03 to -4.62; P = 0.02) and duration was -0.57 (95% CI, -0.94 to -0.20; P < 0.001). For depressor angulli oris, amplitude of MUAPs was -47.06 (95% CI, -62.15 to -31.97; P < 0.001) and duration was -2.21 (95% CI, -2.69 to -1.72; P < 0.001). Blink reflex, including R1 (OR, 0.03; 95% CI, 0.01-0.16; P < .001), R2 (OR, 0.04; 95% CI, 0.004-0.29; P < .001), and R2 latency differences (OR, 0.15; 95% CI, 0.05-0.51; P < .001), have significant difference between the two groups, respectively. The findings suggest that laser acupuncture relieve symptoms for patients with Bell's palsy with a duration of greater than 8 weeks.Trial registration: ClinicalTrials.gov Identifier: NCT05846217.

Sphenopalatine ganglion stimulation with one acupuncture needle for moderate-severe persistent allergic rhinitis: study protocol for a multicenter randomized controlled trial.

BACKGROUND: Allergic rhinitis is a symptomatic allergic disease of the nose that affects 10 to 20% of the global population. Chinese otolaryngologists use one acupuncture needle to stimulate the sphenopalatine ganglion because of its potential advantages for treating moderate-severe persistent allergic rhinitis compared with traditional Chinese acupuncture (verum acupuncture); however, little evidence is available to support the wide clinical use thus far. Therefore, we propose a protocol for a parallel, multicenter, assessor-blinded, randomized controlled trial to evaluate sphenopalatine ganglion stimulation with one acupuncture needle compared to verum acupuncture for treatment of moderate-severe persistent allergic rhinitis. METHODS: In the trial, 96 patients previously diagnosed with moderate-severe persistent allergic rhinitis and meeting all inclusion criteria will be allocated to one of two equal therapeutic groups by using a computer-generated randomization list. The interventional group will receive sphenopalatine ganglion stimulation with one acupuncture needle for 4 weeks (once or twice weekly, total four to eight sessions); attending physicians will decide whether the second session is required in a week by examining signs and symptoms. The control group will receive individualized verum acupuncture for 4 weeks (twice weekly, total eight sessions). Follow-up evaluations will be performed 1 month later. The primary outcome measure is the change in the total nasal symptom score from the baseline to week 4. The secondary outcome measures include onset time and duration of effectiveness in every session, change in number of days with moderate-severe persistent allergic rhinitis from the baseline to week 8, change in total immunoglobulin E level and eosinophil count in venous blood from the baseline to week 4, change in Rhinoconjunctivitis Quality of Life Questionnaire score from the baseline to week 4, and clinical waiting time. DISCUSSION: The trial should provide evidence for the benefits of sphenopalatine ganglion stimulation with one acupuncture needle for treating moderate-severe persistent allergic rhinitis, including better change in total nasal symptom score, faster onset time, longer duration of effectiveness, and shorter treatment time.

[Observation on therapeutic effect of moxibustion with thunder-fire herbal moxa stick on xerophthalmia of oligodacrya].

OBJECTIVE: To observe clinical therapeutic effect of moxibustion with thunder-fire herbal moxa stick on xerophthalmia of oligodacrya. METHODS: Seventy cases were randomly divided into an observation group and a control group. The observation group (n=36) were treated with moxibustion with thunder-fire herbal moxa stick at Cuanzhu (BL 2), Yuyao (EX-HN 4), Tongziliao (GB 1), Taiyang (EX-HN 5), Sibai (ST 2), Jingming (BL 1), etc. and massage of acupoints and lacrimal gland around the eye. The control group (n=34) were treated with local dripping Leiran Diyanye. Changes of the main symptoms, tears secretion test, lacrimal membrane breaking time and corneal fluorescent staining before and after treatment were observed in the two groups. RESULTS: After treatment, sensation of dryness and foreign body sensation in the eye, asthenopia and gross symptoms significantly improved (P<0.01) in the two groups, and the observation group in the improvement of the sensation of dryness and foreign body sensation in the eye and the gross symptoms was better than the control group (P<0.05); tears secretion test significantly improved and was better in the observation group than that in the control group (P<0.05); lacrimal membrane breaking time and corneal fluorescent staining were improved in the two groups (P<0.05), and the improvement of lacrimal membrane breaking time in the observation group was more obvious than that in the control group (P<0.05). CONCLUSION: Moxibustion with thunder-fire herbal moxa stick has good therapeutic effect on xerophthalmia of oligodacrya.

[Clinical observation on the method for nourishing blood and moisturizing eye on xerophthalmia].

OBJECTIVE: To observe therapeutic effect of the method for nourishing blood and moisturizing eye on xerophthalmia. METHODS: Fifty-one cases of xerophthalmia were randomly divided into a treatment group and a control group. The treatment group were treated by acupuncture, moxibustion with Chinese medicine, and auricular point pressing, and the control group were treated with dripping of artificial tears. Local symptoms of eyes, tear secretion amount (Schirmer method) and BUT were observed before and after treatment. RESULTS: The total effective rate of 88.5% in the treatment group was better than 52.0% in the control group (P<0.05). CONCLUSION: The method for nourishing blood and moisturizing eye is a better therapy for xerophthalmia.
