What is the origin of the Scalenes?
Origin and insertion It originates from the transverse processes of axis (C2), transverse processes of atlas (C1), and the posterior tubercles of transverse processes of the vertebrae C3-C7. The muscle fibres extend posterolaterally to form a tendon, which inserts into the superior border of the first rib.

What related syndrome can the Scalenes be associated with?
Secondary MPS of scalene muscle is known to be associated with other medical problems such as osteoarthritis, trauma, complex regional pain syndrome (CRPS) and various systemic medical illnesses (1,5).
Why do scalenes get tight?
The scalenes muscles are considered non-postural or fast twitch muscles, meaning they fatigue quickly. When they fatigue and are overworked, the muscle fibers tighten and waste products accumulate, making the neck stiff and sore on each side, and making tilting the neck painful and nearly impossible.
What is scalene anatomy?
Scalene are a group of three pairs of muscles in the lateral neck: scalenus anterior, scalenus medius and scalenus posterior. Sometimes a fourth muscle, the scalenus minimus is present behind the lower portion of the scalenus anterior.
What causes scalene muscle pain?
Activities that can cause scalene muscle pain are whiplash; excessive coughing; sufferers of breathing conditions such as COPD, asthma, and emphysema; extended periods of head tilted; sleeping on stomach with head to one side; carrying something heavy such as a backpack or purse; pulling or lifting with the arms at …
Do Scalenes rotate the neck?
Conclusions: All 3 scalene muscles produce rotation of the cervical spine to the same side. Maximum stretching of the scalenes should include rotation to the opposite side.
What are Scalenes in your neck?
What are your Scalenes? The Scalenes are a muscle group that help stabilize, flex (bend forward), laterally flex (tilt the head to the side), and rotate the neck. They also help raise your upper two ribs when you inhale, meaning they are working every time you breathe.
What causes Costoclavicular syndrome?
A scissoring action of the clavicle against the first rib narrows the costoclavicular passage and shears the neurovascular bundle. The first rib elevates toward/against the clavicle. This often occurs in clients who have laboured breathing. Tight anterior and middle scalenes and subclavius can also cause this to occur.
What is thoracic outlet syndrome caused by?
Common causes of thoracic outlet syndrome include physical trauma from a car accident, repetitive injuries from job- or sports-related activities, certain anatomical defects (such as having an extra rib), and pregnancy.
What are scalenes and how do they affect the neck?
The scalenes are implicated in a number of neck maladies. Below are a few of the more common ones. Torticollis: Torticollis, also known as wry neck, is a condition in which your neck muscles stay contracted in chronically shortened positions.
What is scalene myofascial pain syndrome?
Pathologies: Scalene myofascial pain syndrome is a regional pain syndrome wherein pain originates over the neck area and radiates down to the arm. This condition may present as primary or secondary to underlying cervical pathology. Trigger point activity in the Scalene muscle group plays a significant role in many upper body pain complaints.
What is the origin of the posterior scalene muscle?
The posterior scalene muscle has its origin at the posterior tubercula of the transverse processes of the 5th to 7th cervical vertebrae and its insertion at the second rib.
What causes referred pain and numbness in the scalene muscle?
When the referred pain is due to MPS of the scalene muscle, the referred pain and numbness can be due to brachial plexus irritation as a result of direct compression between two scalene muscles (3,5). This phenomenon justifies the established fact that MPS of the scalene muscle is one of the causes of TOS.
