Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, and currently, manual repositioning techniques are often used for treatment. However, up to 30%-50% of patients may experience residual symptoms such as non-rotational dizziness, heaviness, instability, and emotional disturbances even after successful repositioning, which significantly impacts their daily functioning and quality of life. Electroacupuncture therapy has been proven to be an effective treatment for dizziness and has been applied to various vestibular disorder patients. However, the efficacy of electroacupuncture on the residual effects of successfully repositioned BPPV patients remains unclear. This study aims to explore the effectiveness of three regimens: electroacupuncture, betahistine in patients with residual symptoms after successful manual repositioning.
According to the diagnostic criteria and therapeutic efficacy evaluation for benign paroxysmal positional vertigo (BPPV) formulated by the Otolaryngology-Head and Neck Surgery Branch of the Chinese Medical Association, the patient was confirmed as having BPPV and the repositioning maneuver was successful.
After the maneuver, the patient's clinical symptoms were relieved, with no sense of rotation or dizziness, but residual symptoms such as discomfort and unsteady gait persisted.
There were no obvious communication barriers or visual impairments.
The patient and their family members agreed to the treatment plan.
Patients with other ear diseases, history of head trauma or surgery;
Patients who are weak and unable to tolerate, pregnant women;
Patients who have undergone vestibular rehabilitation training before this treatment; ④ Patients with joint diseases that affect balance and walking; ⑤ Patients with a history of brain organic diseases (such as tumors, stroke, cerebral hemorrhage) or severe neurological diseases; ⑥ Patients with incomplete data or who withdraw from treatment midway.

Group A
Procedure/SurgeryAcupoint selection: The location of the vertigo-auditory area follows the positioning standard of Jiao Shunfa's Head Acupuncture. Operation: Electroacupuncture stimulation in the vertigo-auditory area of affected side. Pulse electrotherapy produced by Wujin Changcheng Medical Instrument. Sparse-dense waveforms are selected, with a voltage of 2-4V, a frequency of 60-80 times/min, and the intensity is determined by the patient's tolerance. The needle is in affected side for 30 minutes, and treatment is given once daily for a total of 5 days.
Group B
DrugThe original text is related to a medication called Pitavastatin Calcium Tablets, commonly known as "Minshilang" in Chinese, produced by Weicai (China) Pharmaceutical Co., Ltd. The dosage is 12mg, three times a day (Tid) for four consecutive weeks. Compliance monitoring is conducted by counting the remaining tablets in the medication packaging box brought by patients during the 4-week follow-up period. Concurrent use of other medications that may affect the observation results, such as anti-anxiety drugs, vestibular suppressants, and anti-dizziness Chinese patent medicines, is considered a violation of the protocol.
Visual Analog Scale (VAS) score
A scale used to evaluate the degree of dizziness in patients, scores range from 0 to 10, with higher scores indicating more severe degree of dizziness they feel.
Dizziness Handicap Inventory
Self-perceived handicapping effects imposed by dizziness. Internal consistency (Cronbach's alpha: 0.92), Test-retest reliability r = 0.95
Foam posturography
The sponge-cushion posturing is a quantitative method for measuring postural stability. The test-retest reliability of sponge-cushion posturing is good (ICC = 0.887-0.973)
