Description

Technical Field

[0001] The invention relates to a diagnostic and therapeutic device for otolith repositioning, and in particular to an otolith repositioning diagnostic and therapeutic device for people with limited mobility. Background Art

[0002] Benign paroxysmal positional vertigo (BPPV), commonly known as "otolithiasis", is a peripheral vestibular disease induced by changes in head position relative to gravity, characterized by recurrent episodes of transient vertigo and characteristic nystagmus.

[0003] The pathogenesis of BPPV is that otoliths located on the vestibular otolith membrane fall off and gather in the semicircular canals, causing vertigo due to the effect of gravity as the body position changes. Among the BPPV patients who seek clinical treatment, 60% to 90% have unknown causes and are idiopathic BPPV. The disease can also be secondary to trauma, surgery and inner ear diseases.

[0004] The exact pathogenesis of BPPV is still unclear, and the currently recognized theories include canalolithiasis and crestolithiasis.

[0005] According to the cause and the affected semicircular canals, BPPV can be divided into posterior semicircular canal BPPV: accounting for about 70% to 90%, of which cristalithiasis accounts for about 6.3%; lateral semicircular canal BPPV (horizontal semicircular canal BPPV): accounting for about 10% to 30%. According to the type of nystagmus during the roll test, it can be further divided into geotropic nystagmus and alotropic nystagmus, of which geotropic nystagmus accounts for the vast majority; anterior semicircular canal BPPV: a rare type, accounting for about 1% to 2%; multiple semicircular canals BPPV: multiple semicircular canals on the same side or bilateral semicircular canals are affected at the same time, accounting for about 9.3% to 12%. Among them, posterior semicircular canal BPPV and horizontal semicircular canal BPPV are the most common, while superior semicircular canal dehiscence and compound semicircular canal BPPV are less common.

[0006] The Chinese Medical Association's Otolaryngology-Head and Neck Surgery Branch (2007, 2017), the American Academy of Otolaryngology-Head and Neck Surgery (2008), the American Academy of Neurology (2008) and the Barany Society (2015) have respectively published BPPV-related diagnosis and treatment guidelines or standards.

[0007] The first recommended treatment for BPPV is otolith repositioning therapy. Common repositioning methods for posterior semicircular canal BPPV and horizontal semicircular canal BPPV include Epley method and Barbecue method. Manual repositioning can be done manually or with the help of otolith repositioning equipment, and the effect is good.

[0008] The Epley method is recommended as the first choice for treating posterior semicircular canal BPPV. The specific steps of the Epley method are as follows: 1. The patient changes from a sitting position to a supine position; 2. The head is extended to a hanging position and turned 45 degrees to the affected side; 3. The head is turned back to the midline position and 45 degrees to the healthy side; 4. The body is rotated to the healthy side and the head is turned down to 45 degrees to the horizontal plane; 5. Maintaining this head position, the patient returns to a sitting position with the chest tucked in and the head lowered 30 degrees.

[0009] The Barbecue method is often used to treat horizontal geotropic nystagmus caused by BPPV of the external semicircular canal (including horizontal geotropic nystagmus that can be converted to geotropism). The Barbecue method is as follows: 1. The patient sits on the treatment bed, twists the head 90° to the healthy side, and quickly lies flat; 2. The body is turned 180° to the healthy side, the head is turned 90°, and the tip of the nose is facing downward; 3. The body is continued to be turned toward the healthy side until it is lying on the affected side; 4. The patient sits up.

[0010] For patients with intact mobility, it is easy to complete the above-mentioned BPPV treatment process through limb movements or existing treatment instruments. However, some patients with limited mobility or upper limb paralysis cannot complete the above-mentioned treatment movements by themselves or with existing instruments. It is urgent to develop an otolith repositioning diagnosis and treatment device for these patients. Summary of the invention
