1
Normally, only with head movement does fluid within the inner ear also move, informing the brain that a head turn occurred.
2
However, should a crystal called an otolith gets displaced into the posterior canal of the inner ear, BPPV dizziness occurs.
3
Fluid movement occurs due to the crystal rather than head turns
4
causing the brain to think movement has occurred even though none has happened.
5
The Epley maneuver is performed to treat this posterior canal BPPV by trying to get the loose crystal out of the canal.
6
This maneuver is started by turning the head 45 degrees
7
and the body laid back such that the head is extended about 20 to 30 degrees.
8
If BPPV is present, eye twitching called nystagmus will occur.
9
After 30 to 60 seconds, the head is turned 90 degrees to the opposite side and held for another 30 to 60 seconds.
10
The head is then further rotated another 90 degrees, accomplished by having the patient turn onto their side,
11
which is then held for another 30 to 60 seconds.
12
At this point, the head should be turned 45 degrees from the horizontal.
13
When performing this maneuver, another individual can help with these position changes.
14
The maneuver is then completed by having the patient sit up.
15
So what's going on with these position changes?
16
Essentially, the head is moved in such a way to manipulate the crystal to fall towards the canal opening.
17
With each position change, it takes about 30 to 60 seconds for the crystal to settle into the most dependent position in the canal.
18
If turns are made before the crystal has a chance to settle, the crystal may fall back the wrong way and the maneuver will fail.
19
It's also important that the head positions are angled correctly
20
or else the crystal will not settle to the correct position in the canal and the maneuver will fail.
21
Also, if the position changes are done too slowly, the crystal may not settle quickly enough from lack of momentum and the maneuver will also fail.
22
Once the crystal falls out of the canal, the dizziness should resolve if due to posterior canal BPPV.

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
