Background Patients with musculoskeletal disorders, such as osteoarthritis (OA) and rheumatoid arthritis (RA) suffer from not only pain but also insomnia, day time sleepiness, and other sleep disturbances. Poor sleep may also affect disability in musculoskeletal disorders. However, in the previous study, there was less data about the comparison of quality of sleep (QOS) and quality of life (QOL) in OA and RA patients.

Objectives In this study, we aimed to assess the impact of OA on QOS comparing it with that of RA patients and control subjects. We also studied the QOS and QOL of these two musculoskeletal disorders.

Methods 149 patients with OA, 130 patients with RA, and 117 voluntary control subjects participated in the study. The groups were compared in terms of demographic characteristics. QOS was evaluated by using the PSQI (Pittsburgh Sleep Quality Index) Health Survey and ESS (Epworth Sleepiness Scale) in all study participants. The Pain VAS (Visual Analog Scale) and McGill Pain Questionnaire were used to evaluate significant pain experienced by OA and RA patients. QOL was estimated by using Korean versions of the SF-36 (Short Form 36).

Results The subjective sleep quality, sleep latency, sleep duration, sleep disturbance, use of sleeping medication, and total PSQI score were higher in OA and RA patients than in control subjects (p<0.05). The between-groups comparisons revealed that OA patients had significantly scored high in sleep latency, sleep duration, habitual sleep efficiency, and total PSQI score than RA patients (p<0.05). All parameters of McGill Pain score and Pain VAS score were significantly higher in OA than in RA patients (p<0.01). The total SF-36 score was lower in OA patients than in RA patients (51.02±20.68 vs. 60.05±20.82, respectively, p<0.01). The PSQI score correlated with McGill Pain Questionnaire, Pain VAS, and total SF-36 score in OA (p<0.05) and RA (p<0.01). Pain VAS also correlated significantly with the total PSQI score and total SF-36 score in OA (p<0.01) and RA (p<0.01).

Conclusions Looking at the study’s findings, we need a slightly different approach on evaluating patients with either OA or RA suffering from sleep disturbance. The pain score is associated with QOS and QOL in OA and RA patients; thus, appropriate pain control of OA and RA patients could lead to improve their QOS and QOL.
