Effects on Rounded Back, Sloping Shoulders, and Neck-Shoulder Line Improvement?

Hello. This is SIO Clinic.

​

Have you ever felt heaviness and stiffness in your neck and shoulders,

or noticed your shoulders are rounded when looking at your side profile in the mirror?

​

Especially with prolonged computer use or

the habit of looking down at your smartphone,

it can put a strain on the muscles around the neck and shoulders,

leading to postural imbalance.

​

These changes are not just aesthetic

concerns but can also cause

various discomforts such as fatigue and muscle tension in the neck and shoulders.

01. Rounded Back & Turtle Neck: Is it just a posture problem?

​

A turtle neck refers to a posture where the head protrudes forward from the body.

​

In a normal posture, the weight of the head

is distributed relatively evenly along the spine,

but as the head juts forward,

the burden on the neck muscles increases.

​

When accompanied by rounded shoulders (shoulders rolling forward)

and kyphosis (rounded upper back),

the alignment of the neck and shoulders changes further.

​

Muscles connecting the neck and shoulders,

such as the upper trapezius and levator scapulae,

may show continuous tension to maintain posture.

​

If this condition persists for a long time,

it can cause fatigue and stiffness in the muscles,

and can also lead to a short and blunt neck-shoulder line.

However, turtle neck and rounded back are not caused by a single muscle issue.

Spinal alignment, joint mobility,

muscle balance, and lifestyle habits

all interact complexly, making it important to identify the cause.

​

02. Trapezius Botox, also known as Wedding Botox

Recently, as more people focus on the silhouette of their neck and shoulders,

interest in trapezius Botox is also increasing.

​

Especially when wearing outfits that expose the shoulders, like dresses,

some people consider the procedure if they are concerned about their neck appearing short

or their trapezius muscles being prominent.

​

Trapezius Botox uses the principle of temporarily inhibiting nerve-muscle signal transmission

by injecting botulinum toxin into the trapezius muscle.

​

This reduces excessive muscle contraction,

and over time, the muscle volume may decrease

depending on its usage.

​

​

If the trapezius muscles are significantly developed,

the shoulder line may appear relatively softer and more gradual.

​

However, trapezius Botox alone does not correct

the structural alignment of a rounded back or turtle neck.

​

Therefore, it is advisable to approach posture correction

and muscle volume reduction procedures separately.

03. Trapezius Botox: A Procedure Considering Muscle Structure

Turtle Neck & Trapezius Botox::SIO Clinic

The trapezius is a large muscle that starts from the back of the neck

and extends broadly to the shoulders and back.

​

It is divided into upper, middle, and lower parts,

and each part plays a different role in the movement of the shoulders and scapula.

​

The upper trapezius, in particular, is an important muscle involved

in lifting and rotating the scapula.

​

Therefore, simply injecting a large amount of Botox

just because the trapezius muscles are developed is not always the best approach.

​

​

It is necessary to consider the muscle thickness and development,

left-right asymmetry, and shoulder movement comprehensively.

​

Overly inhibiting muscle function can weaken the ability to lift the shoulders

or cause discomfort in daily movements.

​

SIO Clinic emphasizes the importance of carefully determining the injection area and

necessary dosage, considering these anatomical characteristics.

04. Detailed Muscle Evaluation Using Ultrasound

​

​

One of the important factors when considering trapezius Botox

is to check the actual condition of the muscles.

​

It can be difficult to assess muscle thickness and structure

based solely on the apparent height of the shoulders or

the prominence of the trapezius muscles.

Ultrasound examination can help in real-time assessment of muscle thickness and

the position of surrounding tissues.

Understanding the individual's unique muscle shape and

development patterns can help in creating a more detailed treatment plan.

​

However, using ultrasound does not prevent all side effects

or guarantee treatment results.

​

What is important is an appropriate treatment plan

that considers anatomical understanding and

the individual's muscle condition.

05. Neck-Shoulder Line Changes: What to Look for in Before & After Photos

The most anticipated aspect for those considering trapezius Botox

is the actual change in the shoulder line.

​

In cases of excessive trapezius muscle development,

after the procedure, as the muscle volume decreases,

you can expect a change where the prominent shoulder contour appears softer.

​

However, the effects of botulinum toxin are not immediate.

​

​

It takes time for muscle activity to gradually decrease

and for volume changes to become apparent.

​

The degree of effect and duration of results can also vary individually

depending on muscle mass, dosage injected, and lifestyle habits.

​

​

Furthermore, when comparing before and after photos,

it is important to consider the shooting angle, shoulder position,

and differences in posture.

​

It is important to remember that Botox is a procedure to adjust muscle volume,

not a treatment to change the spinal alignment itself.

06. Turtle Neck and Rounded Back: Muscle Balance is Key

If you have a turtle neck or rounded shoulders,

simply relaxing the trapezius muscles will not solve all the problems.

Around the neck and shoulders, in addition to the trapezius,

various other muscles such as the levator scapulae, pectoralis muscles, and serratus anterior are involved.

Some muscles may be excessively tense while

others are relatively weak, leading to persistent postural imbalance.

​

Therefore, if you experience discomfort related to posture,

evaluating the condition of your muscles and joint mobility,

and if necessary, combining it with stretching, strengthening exercises,

and lifestyle improvements can be helpful.

​

​

Trapezius Botox is a separate procedure that can be considered selectively

based on the degree of muscle development.

​

Especially if accompanied by chronic pain, numbness, or muscle weakness,

it is important to seek a precise diagnosis to identify the cause,

rather than assuming it is simple muscle tension.

07. Choosing for a Natural Neck-Shoulder Line

A beautiful neck and shoulder silhouette

is not achieved simply by having small trapezius muscles.

​

It is important for the neck length, shoulder slope,

muscle balance, and overall posture to harmonize.

​

SIO Clinic emphasizes an approach that considers

the individual's body structure, muscle development,

and functional aspects, rather than just muscle reduction.

​

​

If you are considering turtle neck or trapezius Botox,

it is necessary to first distinguish whether your discomfort is due to posture

or an aesthetic concern related to muscle development.

​

Remember that the choice for a natural neck-shoulder line

begins with understanding your current condition.
