title: Reduced inclination of cervical spine in a novel notebook screen system - implications for rehabilitation.
abstract: BACKGROUND
  Professional working at computer notebooks is associated with high requirements on the body posture in the seated position. By the high continuous static muscle stress resulting from this position at notebooks, professionals frequently working at notebooks for long hours are exposed to an increased risk of musculoskeletal complaints. Especially in subjects with back pain, new notebooks should be evaluated with a focus on rehabilitative issues.
  
  
  METHODS
  In a field study a new notebook design with adjustable screen was analyzed and compared to standard notebook position.
  
  
  RESULTS
  There are highly significant differences in the visual axis of individuals who are seated in the novel notebook position in comparison to the standard position. Also, differences are present between further alternative notebook positions. Testing of gender and glasses did not reveal influences.
  
  
  CONCLUSIONS
  This study demonstrates that notebooks with adjustable screen may be used to improve the posture. Future studies may focus on patients with musculoskeletal diseases.
