Thoracic
            Outlet Syndrome
          
        
What is Thoracic
              Outlet Syndrome?  
        Thoracic Outlet Syndrome is a condition which involves
          compression of either blood vessels (Subclavian Artery,
          Subclavian Vein) or nerves (Brachial
              Plexus) in the shoulder and back.
        
        What are the
                Symptoms of Thoracic Outlet Syndrome?
        
         Common symptoms include pain throughout the arm
            including the fingers, hands, and arms (especially the inner
            side of arms), the neck, the pectorals and the trapezius /
            rhomboid area of the back.  In serious cases, the
            affected hand may be noticeably colder, discolored (due to
            lack of blood flow), and may even experience a 'pins and
            needles' sensation (numbness).
        
        What Causes Thoracic Outlet Syndrome to Develop?
          
        Most commonly Thoracic Outlet Syndrome arises from physical
          trauma causing acute pressure which results in compression of
          the Subclavian Artery/Vein or more commonly
          the Brachial Plexus.  Another common
          source is repetitive strain injury from work related tasks
          (especially when repeatedly Overreaching
          for the mouse or other work materials).  Thoracic Outlet
          Syndrome can also arise from spasms or enlargements which
          result in compression of the affected blood vessels or
          nerves.    
         
        What Movements Should be Avoided if you
              have Thoracic Outlet Syndrome?
            
        Try to engage in more movement and stretches as opposed to
          static awkward postures.  This can assist in relieving
          pressure in the thoracic cavity.  Ensure that good
          posture is maintained while sitting (i.e. avoiding 'slouching'
          or 'leaning' into the arm rest of the chair).  It is also
          often the case that performing tasks while fully Pronated
          and with Wrist
            and Finger Extension and minimal arm movement will also
          increase discomfort.
        
         
        What Types of Products can be Used to
              Help Prevent or Reduce the Symptoms and Incidence of
              Thoracic Outlet Syndrome?
            
        Overreaching can be avoided by 
Corner
          Converters, 
Writing
          Surfaces, 
Document
          Holders, 
Book
          Holders and 
Compact
          Keyboards.
        
To help prevent Wrist
            Extension, Articulating
            Keyboard Arms or Adjustable
            Height Workstations will ensure the proper height for
          using keyboards and mice.
        To assist in reducing Pronation,
          consider Orthopedic
            Mice or Vertical
            Mice which reduce or eliminate the requirement to
          pronate while mousing.  Also consider Adjustable
            Keyboards to reduce the degree of Pronation
          required to keyboard.
