LDP causes weakness in the muscles relating to vocalization

When the larynx is in a deepened position, it causes weakness in the muscles relating to vocalization.
The muscles directly associated with LDP relating to vocalization are thin with a narrow range of motion. This is because the muscle strength is proportional to the area of muscle mass.
The longer you have LDP, the worse your weakened muscle status becomes. If you feel choking and/or it is difficult for your throat or voice to sing a song, than you should not just stand by. You should consider all three of the following treatment options.
To resolve LDP is 1: Flexibility of musculus extrinsic laryngis, including muscles relating to vocalization.
and 2: Forward displacement of the larynx.
Recently, through real-life case studies, we found 3: Increasing muscle strength (daily exercise routines) relating to vocalization is also an important factor to repair/fix LDP.
Even if circumstances of 1 and 2 are met, it is common for people to have LDP return again. This is because the root cause is still unknown.
As a Voice Care Professional, I firmly believe to prevent a recurrence of LDP, 3 is also needed after fixing 1 and 2.
If muscle strength is improved and the range of motion in the muscles relating to the vocalization returns, both will increase preventing a future recurrence, and it will be easier to let out the voice as well as having noticeable better singing abilities. Furthermore, if you also focus to improve the cricothyroid muscle’s strength, you’ll see your voice range is going to be wider.
LDP(Larynx deep position) is the abbreviation, which refers to the process in which the larynx gets in deeper than normal and the muscles relating to vocalization stiffen. This is a treatable condition, not an incurable disease.

Note1:LDP mostly contracts the cricothyroid muscle.
Note2:You can work to acquire A.Stretching the pharyngeal cavity. B.Improving the epiglottis standing up C.Ease by gently pressing the vagus nerves(recover from a cough) D. Improving the motion range of the cricothyroid articulation (Required for a high-pitch voice)
