Sleep disturbance is common in carpal tunnel syndrome (CTS), and we hypothesize that it has an important impact on the quality of life of CTS patients. The characteristic of sleep problems associated with CTS has not been evaluated.
We performed a case–control study to measure the association between a variety of sleep disturbances and CTS. Sixty-two cases with clinically diagnosed CTS and a probable or classic hand diagram were compared to 138 primary care patients without CTS. In addition to demographic features, we collected the nature of sleep disturbance experienced by the patients from a categorical list and the nature, impact, and severity of sleep disturbance using the Insomnia Severity Index.
Patients with CTS complained of significantly more severe problems with sleep than the control population and had multiple sleep complaints compared to the control group. Sixty-three of the 138 control patients indicated that they had one cause of sleeping disturbance with no control patient choosing more than one. In contrast, in CTS patients, 44 of 63 patients indicated they had two or more causes of sleep disturbance. The Insomnia Severity Index was significantly higher in CTS patients and the impact of sleep disturbance on quality of life was higher in the cases.
Sleep disturbance in CTS patients is characterized by a broad array of physical symptoms that have a significant impact on quality of life.
