文摘

Frequently the symptoms of the carpal tunnel syndrome (CTS) occur at night time (Patel et al., 2014), but the relation between CTS and the sleep characteristics of those patients (Lehtinen et al., 1996) have yet to be systematically described by objective methods, such as electroneuromyography (ENMG) and polysomnography (PSG), which is the aim of this study.

Methods

Consecutive female patients with CTS diagnosed by conduction studies (ENMG) were studied by polysomnographic exams and listed in accordance with CTS severity, evaluated by distal motor latency of the median nerve of the affected hand or hands, and their polysomnographic data was analysed.

Results

42 patients were studied from June 2011 to June 2015. The Arousal Index (AI) of the patients with severe CTS were altered in a larger proportion of those individuals (100%) than in those patients with slight or moderate CTS, 60% and 66%, respectively, (Table 1). This relation was also prevalent when the Desaturation Time (DT) was analyzed. Alterations of the Sleep Efficiency (SE) were more common among patients with bilateral CTS. Sleep architecture was equally altered among all patients, with slow wave sleep (SWS) and REM sleep diminished in all groups. The presence of Sleep Apnea was not dependent of the CTS severity.

Conclusions

The larger the CTS severity evaluated by ENMG, more prevalent were the fragmented sleep and sleep desaturation. Further analysis is required to ascertain causal relations between sleep quality and CTS severity.
