What is Upper Cross Syndrome??

Upper-crossed syndrome (UCS) is a condition of muscular imbalance that impacts the upper body, primarily the neck, shoulders, and upper back. It is also referred to as proximal or shoulder girdle crossed syndrome, and it arises due to inequity between the tautness and feebleness of specific muscle groups. Joint dysfunction is caused by this pattern of imbalance, especially at the T4-T5 segment, atlanto-occipital joint, C4-C5 segment, cervicothoracic joint, and glenohumeral joint. According to Janda, these core areas of stress in the spine complies to transitional zones where the morphology of nearby vertebrae changes.

What causes UCS?

Poor posture is the main contributor to UCS. Long periods of time spent driving, using a computer, or sitting at a desk cause people to slump forward, which can cause their shoulders to round and their neck to protrude forward. The upper trapezius, levator scapula, pectoralis major, and minor muscles are overworked and strained as a result of this posture. At the same time, muscle imbalances develop due to the weakening and underuse of the lower trapezius, middle trapezius, and deep cervical flexors.

Injuries to the neck or shoulders, such as whiplash, as well as repetitive strain injuries brought on by performing the same activities repeatedly can also contribute to the development of UCS. Stress, which can make people tense up their muscles and exacerbate muscle imbalances, can also be a factor.

Symptoms of UCS?

UCS can cause a variety of symptoms, but the most common ones are pain, stiffness, and restricted motion in the neck, shoulders, and upper back.

Headaches, exhaustion, and upper body weakness may also be present. Along with poor posture, people with UCS may also experience tingling or numbness in their arms and hands.

UCS is characterized by specific postural changes, such as forward head posture, a rise in cervical and thoracic kyphosis, elevated and protracted shoulders, rotation or abduction of the scapulae, and winging of the scapulae. 

Due to the weakening of the serratus anterior, which causes the glenoid fossa to become more vertical and causes the scapulae to rotate, abduct, and wing, these postural changes reduce the stability of the glenohumeral joint. To maintain glenohumeral uniform distribution in the face of this loss of stability, the upper trapezius and levator scapulae must become more active.

Diagnosis of UCS

Physical Examination:

The first stage of the UCS physical examination is posture assessment. The doctor looks at the patient's posture while they are standing to look for any deviations from the head, shoulders, and spine's natural alignment. A common indicator of UCS is a forward head posture, in which the head protrudes forward and the cervical spine is stretched out. Another sign of tightness in the pectoralis muscles and weakness in the middle and lower trapezius is rounded shoulders and a hunched upper back.

Testing your range of motion (ROM) is essential when assessing your UCS. To detect any restrictions or pain during movement, the clinician evaluates the patient's ability to move their head, neck, and shoulders through their full range of motion. Tightness in the upper trapezius and levator scapulae may be the cause of the limited range of motion in the neck's flexion, extension, and rotation. Additionally, restricted external rotation and shoulder abduction may be signs of pectoralis muscle tightness.

Muscle strength testing is another crucial component of the physical examination for UCS. Weakness in the deep cervical flexors and middle and lower trapezius muscles is commonly observed in patients with UCS. The clinician may use manual muscle testing techniques to evaluate muscle strength and identify any muscle imbalances.

Palpation can also be used to locate tender or constricted areas in the affected muscle groups. To locate any areas of tightness or tenderness, the therapist may palpate the upper trapezius, levator scapulae, pectoralis major and minor, as well as the middle and lower trapezius muscles.

Finally, the clinician might perform unique tests to assess particular joints affected by UCS. For instance, the cervical flexion-rotation test may be used to evaluate joint dysfunction at the C1-C2 segment and atlanto-occipital joint. Glenohumeral joint dysfunction may be evaluated using the shoulder impingement test.

Treatment:

• Physical Therapy: The first course of action for UCS is frequently physical therapy. To correct muscle imbalances, a physical therapist can work with the patient to create a personalized exercise regimen that includes stretching and strengthening exercises. To reduce pain and restore joint function, the therapist may also employ manual therapy techniques like massage or joint mobilization.
• Postural Correction: A key component of treating UCS is correcting posture. In order to reduce the strain on the upper body muscles, patients may need to learn how to sit and stand correctly.
• Ergonomic Adjustments: In order to stop the onset of UCS, patients may need to make adjustments to their working environment, such as raising or lowering their chair or computer monitor.
• Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs), which reduce pain and inflammation in the affected muscles, may be prescribed.
• Surgery is rarely necessary to treat UCS, but it might be if the muscle imbalances are brought on by a structural issue or injury.

In conclusion, developing healthy habits like maintaining good posture, stretching frequently, strengthening weak muscles, taking frequent breaks, and using ergonomic equipment are all important steps in preventing UCS. You can avoid UCS and maintain a healthy musculoskeletal system by incorporating these lifestyle changes into your daily routine.
