Arterial TOS occurs when an artery is compressed. Resolution of symptoms occurred only afterthoracicoutletdecompression. In my experience, its a great and even potentially dangerous myth to assume that these tight muscles are over active and mandate release.

My posture has always been quite bad. Relative utility of different electrophysiologic techniques in the evaluation of brachial plexopathies. Thats what I think this mewing trend is missing. We were more impressed with the deep cervical fascia as the cause of intermittent rotational obstruction rather than the anterior scalene muscle.

So far, the key points that we have talked about are: Itis absolutely critical to establish proper breathing habits, clavicular resting position and cervical posture, in order to resolve thoracic outlet syndrome. South Med J. In neurogenic TOS, neurogenic symptoms occur in the upper extremity and may radiate to the shoulder, neck, and occipital regions if the upper trunk is involved; Raynaud phenomenon is frequently seen due to an overactive sympathetic nervous system, whose fibers run along the C8 and T1 nerves. Patients with thoracic outlet syndrome will most likely present pain anywhere between the neck, face and occipital region or into the chest, shoulder and upper extremity and paresthesia in the upper extremity. The axillary nerve passes through the quadrangular interval, and will usuallybe compressed between the teresminorand teres major. comes under pressure, oxygen supplied to the affected part of the body is diminished. Signal strength indicates the amount of blood that travels at the given speeds, and is thus quantitative. Dont get me wrong though; strengthening workis important.
