Adson’s test for anterior scalene syndrome version of thoracic outlet syndrome. The client is asked to rotate the neck ipsilaterally, flex it laterally to the opposite side, and extend the head and neck while the therapist palpates the strength of the radial pulse.
The term ‘thoracic outlet syndrome’ describes compression of the neurovascular structures as they exit through the thoracic outlet (cervicothoracobrachial region). The thoracic outlet is marked by the anterior scalene muscle anteriorly, the middle scalene posteriorly, and the first rib inferiorly.

Thoracic outlet syndrome is a neurovascular disorder resulting from compression of the brachial plexus and/or subclavian vessels in the interval between the neck and axilla. Diagnosis can be suspected clinically with specific provocative tests and supplemented with radiographs or vascular studies. showing anatomic causes of compression.
Compression of the blood vessels and nerves can cause shoulder and neck pain. It also can cause numbness in the fingers. Common causes of thoracic outlet syndrome include trauma from a car accident, repetitive injuries from a job or sport, and pregnancy.
Thoracic outlet syndrome (TOS) manifests when pressures in the thoracic outlet increase to the point of impinging vessels or nerves. These pressures can result from several anatomical abnormalities, such as the thoracic ribs or space-occupying lesions, including tumors or cysts.
Abstract. The diagnosis of thoracic outlet syndrome (TOS) has long been a controversial and challenging one. Despite common presentations with pain in the neck and upper extremity, there are a host of presenting patterns that can vary within and between the subdivisions of neurogenic, venous, and arterial TOS.
