title: Actigraphic Analysis of Patients with Cervical Disc Herniation.
abstract: OBJECTIVE
  To analyze the relationship between the severity of pain and sleep disorder using wrist actigraphy in patients with cervical disc herniation (CDH).
  
  
  METHODS
  Fifty patients with the diagnosis of CDH underwent subjective tests and actigraphic analysis in preoperative period, and at the end of postoperative first week and postoperative first month. The data of the subjective tests and actigraphic analysis were compared.
  
  
  RESULTS
  There was a strong and statistically significant negative correlation between the subjective tests of Visual Analog Scale (VAS) for Pain 0-1-2 and the objective parameters of Sleep Onset Latency (SOL) 0-1-2 (rs= -0.798, p=0.009 - rs= - 0.832, p=0.006 - rs=- 0.710, p=0.004). There was a positive correlation between the subjective tests of VAS for Pain 0-1-2 and the objective parameters of Sleep Efficiency (SEF) 0-1-2 (rs=0.721, p=0.006 - rs= 0.768, p=0.001 - rs= 0.748, p=0.001).
  
  
  CONCLUSIONS
  Actigraphy may be used for the evaluation of cervical disc surgery, as an alternative and objective test for sleep disorders.
