This study aimed to determine differences in sleep quality between
patients with mechanical neck pain, patients with whiplash (WAD) pain, and
healthy controls and to determine the relationship between the intensity of
ongoing pain, disability, and sleep quality.
DESIGN: Nineteen patients with
mechanical neck pain (4 men, 15 women; age, 40 +/- 16 yrs), 22 with WAD (4 men,
18 women; age, 38 +/- 15 yrs), and 18 comparable controls (4 men, 14 women; age,
41 +/- 13 yrs) completed the Pittsburgh Sleep Quality Index to assess sleep
quality. A numerical pain rate scale (0-10) and the Neck Disability Index (0-50)
were collected for assessing neck pain and disability. RESULTS: Significant
differences in sleep quality (P < 0.001), sleep latency (P = 0.005), sleep
efficiency (P = 0.002), sleep disturbances (P < 0.001), use of sleeping
medication (P < 0.001), daytime dysfunction (P < 0.001), and total Pittsburgh
Sleep Quality Index score (P < 0.001) but not for sleep duration (P = 0.096) were
found; patients with mechanical neck pain and WAD pain exhibited higher scores in
all components compared with healthy controls. Seventeen (77%) patients with WAD
and 13 (68%) with mechanical neck pain reported poor sleep quality (Pittsburgh
Sleep Quality Index score, >8). Significant positive correlations between mean
intensity of ongoing pain with sleep quality (rs = 0.693; P < 0.001); sleep
duration (rs = 0.433; P = 0.044); sleep efficiency (rs = 0.644;
P = 0.001) and
total Pittsburgh Sleep Quality Index score (rs = 0.643; P = 0.001) were found in
patients with WAD pain; the higher the intensity of ongoing pain, the worse the
sleep quality. CONCLUSIONS: Sleep disturbances are a common finding in
individuals with neck pain and are associated with the intensity of ongoing pain
in WAD. It seems essential to address the ongoing cycle of pain and sleep
disturbances as an integral part of the treatment of patients with neck pain.
