Understanding Thoracic Outlet Syndrome

A Comprehensive Guide to Treatment Options

As an active adult a complaint like neck and shoulder pain really puts a wrench in your weekly activity. There is no good time to take time off at the gym, or maybe you have a competition or a race coming up. You are beginning to notice a slow increase in pain in your neck and even your shoulder. You haven’t necessarily changed much within your daily activities, but pain is still present. You assume that this is just normal and continue on with your life. Sometimes your hand feels colder than normal, or even can get numb or tingly. Again you brush it off like it is just normal. You talk to your friends and family about it and some describe the same type of feeling. With all of this you are still unsure on what to do or who to go to for an assessment. It very well could be Thoracic Outlet Syndrome!

You make an appointment with your local physician. An exam includes a physical assessment including questions about when and what causes symptoms to occur. The physician moves your neck, your shoulder and arm around. They look for any sign of injury both visually along with using functional tests and seemingly odd positions. You are still not entirely sure of what they are looking for. 

At the end of an assessment your physician goes over what is called a differential diagnosis list. What that means is for your symptoms there are multiple conditions that could be causing you the issue. With that  information the next steps are to either require more tests, begin treatment and explain what to expect through treatment and any other option that you may want to choose. 

A difficult part about symptoms like Thoracic Outlet Syndrome is that they overlap other conditions. As previously mentioned, multiple conditions can cause numbness and tingling, or neck and shoulder pain. Below we will go over some specifics of the condition.   

Thoracic Outlet Syndrome

Thoracic Outlet Syndrome (TOS) is a group of disorders that occur when blood vessels or nerves in the space between the collarbone and first rib become compressed. This condition can lead to pain in the shoulders, neck, and upper back, as well as neurological symptoms such as tingling, numbness, and weakness in the hands. Individuals affected by Thoracic Outlet Syndrome often seek relief through various treatment options, including both conservative and medical interventions. This blog aims to provide a detailed overview of Thoracic Outlet Syndrome, its symptoms, and effective treatment strategies available to patients.

Thoracic Outlet Syndrome can be classified into several types based on the structures affected:

1. **Neurogenic Thoracic Outlet Syndrome**: The most common type, caused by compression of the brachial plexus, a network of nerves that innervate the arm.
2. **Venous Thoracic Outlet Syndrome**: Caused by the compression of the subclavian vein, leading to swelling and the risk of blood clots.
3. **Arterial Thoracic Outlet Syndrome**: The rarest type, resulting from compression of the subclavian artery, which can lead to severe complications if not treated.

Symptoms of Thoracic Outlet Syndrome can vary depending on the type and severity of the condition but often include:

• – Shoulder and neck pain
• – Numbness or tingling in the fingers
• – Weakness in the hand
• – Swelling of the arms or hands
• – Coldness in the hands or arms
• – Symptoms worsening with certain arm positions or activities

 Causes and Risk Factors

Various factors can contribute to the development of Thoracic Outlet Syndrome, including anatomical abnormalities, injuries, repetitive motions, or heavy lifting. Common risk factors include:

• – Anatomical abnormalities like an extra rib
• – Trauma to the neck or shoulder
• – Poor posture
• – Repetitive activity involving overhead motions
• – Sedentary lifestyle leading to weakened muscles

To diagnose Thoracic Outlet Syndrome, healthcare providers typically conduct a detailed medical history and physical examination. There may be a need for further examination using imaging tests such as X-rays, MRI, or ultrasound to evaluate the structure of the thoracic outlet. Electromyography (EMG) and nerve conduction studies can help assess nerve function and determine if nerve compression is present.

Treatment for Thoracic Outlet Syndrome

The treatment for Thoracic Outlet Syndrome varies based on the severity of the condition and the symptoms experienced by the patient. Below are the primary treatment options available.

1. **Physical Therapy**: A physical therapist can design a customized exercise program to improve posture, strengthen shoulder and neck muscles, and enhance flexibility. Techniques such as manual therapy, stretching, and specific strengthening exercises can be helpful in managing symptoms and improving function. According to a study published in *Physiotherapy Theory and Practice* physical therapy has shown positive outcomes in patients with TOS (López et al., 2021).

2. **Chiropractic Care**: Chiropractic adjustments can help relieve spinal misalignments and improve mechanics in the thoracic outlet region. Chiropractic techniques may focus on neck and upper back adjustments, soft tissue manipulation, and therapeutic exercises.
3. **Medication**: Over-the-counter pain relievers such as ibuprofen or naproxen can help alleviate pain and reduce inflammation. In some cases, doctors may prescribe muscle relaxants or corticosteroids for more significant pain relief.
4. **Lifestyle Modifications**: Patients are encouraged to make changes to their daily habits, including avoiding repetitive overhead activities and practicing good posture. Ergonomic adjustments to workstations can also be beneficial.
5. **Heat and Cold Therapy**: Applying heat or cold to the affected area can reduce symptoms. Heat can relax tight muscles, while cold therapy can reduce inflammation.

Medical Treatment Options

If conservative treatments fail to provide relief, or if the condition is severe, medical interventions may be necessary.

1. **Medication Management**: In persistent cases, stronger pain medication, anti-inflammatory drugs, or corticosteroids may be used. Some patients may benefit from medications that improve blood flow.
2. **Nerve Block Injections**: Injections of anesthetic or steroids into the affected area can reduce pain and inflammation and may aid in diagnosing the exact source of symptoms (Khan et al., 2020).
3. **Surgery**: Surgical intervention may be considered for patients with severe TOS unresponsive to other treatments. Decompression surgery aims to remove the source of nerve or vessel compression, which may include removing a cervical rib or a portion of the first rib. According to a systematic review by Jain et al. (2021), surgical outcomes are generally positive, with most patients experiencing significant symptom relief.

Thoracic Outlet Syndrome can significantly impact an individual’s quality of life. However, with a comprehensive treatment approach that includes both conservative and medical options, many patients find relief from their symptoms. Physical therapy, chiropractic care, lifestyle modifications, and, when necessary medical interventions are all on the table as options. 

As part of any care plan, having options to focus on this at home, or at the office, becomes imperative to see long term results. The objective is to lessen external environment factors that are controllable for your condition. Utilizing a movement therapy for pain maintenance may be a large part of this condition. Many musculoskeletal conditions improve as we begin to gain the benefits of exercise therapy.
