consulting a physician in these patients. Sleep disorders are in the second place after brachialgia with a ratio of 64% (5,12,24,27).Sleep disorders are frequently seen in patients with chronic low back pain (17). In another study, pain was shown to be the most important factor impairing quality of sleep (23). Other studies demonstrated a significant relationship between the severity of pain and the impairment in sleep quality. It has been also shown that quality of sleep improves after the treatments focusing on the cause of pain (5,6).In addition to chronic pain syndromes, there are a lot of studies on sleep disorders in patients who underwent open heart surgery, major abdominal surgery and thoracic surgery which were targeted to the disease underlying the pain (29). In the █ INTRODUCTION C ervical disc herniation (CDH) is characterized by compression of the motor and sensory tracts of cervical nerve roots (radiculopathy) and/or compression of the motor and sensory tracts of the long pathways in the spinal cord (myelopathy) as a result of degenerative events in the cervical vertebrae. An intractable and severe pain radiating from the neck down to the arm (brachialgia) and progressive neurological deficits associated with radiculopathy and/or myelopathy findings in cervical magnetic resonance imaging (MRI) are the major surgical indications in patients with CDH. The surgical procedure in CDH is at the same time a surgical procedure for pain relief. Brachialgia associated with radiculopathy and myelopathy is the main reason for AIm: To analyze the relationship between the severity of pain and sleep disorder using wrist actigraphy in patients with cervical disc herniation (CDH).
mATERIAl and 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).CONClUSION: Actigraphy may be used for the evaluation of cervical disc surgery, as an alternative and objective test for sleep disorders.
