Objectives Assessing the quality of sleep and the prevalence of sleep disorders in patients with chronic neck pain and identify its determinants.

Methods Cross-sectional study is conducted among patients, older than 18 years and followed for common chronic neck pain over 3 months, recruited at the consultation of Rheumatology. The Exclusion criteria were symptomatic neck pain and all chronic diseases or medication which can affect sleep. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI) (0 = no disorder, 21 = major disorders) grouped into 7 items: subjective sleep quality, sleep latency, sleep duration,habituel sleep efficiency, sleep disturbances, use of sleeping medications and daytime dysfunction

The characteristics of the neck pain were: the duration of the current episode, the presence of vertebral contractures or cervicobrachial neuralgia (NCB), the pain assessed by the visual analogue scale (VAS), functional disability assessed by the Neck disability index (NDI) French version validated, anxiety and depression assessed by Hospital Anxiety and Depression scale (HAD) Arabic version validated. A descriptive statistical analysis anda linear regression were performed

Results 80 chronic neck pain patients were included, the average age of the patients was 51.7±11 years, with a female predominance (83.8%). The median evolution of neck pain was 24 months (12-48 months). The PSQI global score was elevated in 90% of our patients with a mean of 12±3.3. 85% of patients were poor sleepers,Participantsreported an average of 60 min needed tofall asleep each night (sleep latency).The mean hours of actualsleep per night was<6 h (sleep duration). Sleep disorders were present in 85% of patients and a third of participants reported having pain at least three to four times a week. The use of sleeping medication was found in 31% of patients. Sleep difficulties causing a bad daytime functioning in 72% of patients. In univariate analysis, there is a positive relationship statistically significant between the PSQI total score and VAS pain (p=0.021, B =0.248, 95% CI [0.11, 0.129]),the duration of the current episode (p=0.05, B =0.214, 95% CI [-0.001, 0.50]) and the functional disability (NDI) (p=0.01, B =0.283, 95% CI [0.061, 0.456]). No association was found between sleep disorders and the presence of vertebral contractures or cervicobrachial neuralgia.After multivariate analysis, there is a positive relationship statistically significant between sleep disorders, VAS pain (p=0.029, B =0.237, 95% CI [0.003, 0.052]) and functional disability (p=0.042; B =0.247, 95% CI [0.009, 0.442])

Conclusions This study suggests that sleep disorders are common in patients with neck pain. This poor sleep is influenced by the intensity of the pain, which can alter their functional ability
