Preferences in Sleep Position Correlate With Nighttime Paresthesiasin Healthy People Without Carpal Tunnel Syndrome

摘要

Carpal tunnel syndrome has been associated with sleepposition preferences. The aim of this study is to assess self-reported nocturnalparesthesias and sleeping position in participants with and without carpaltunnel syndrome diagnosis to further clinical knowledge for preventive andtherapeutic interventions. A cross-sectional survey studyof 396 participants was performed in young adults, healthy volunteers, and apatient population. Participants were surveyed on risk factors for carpal tunnelsyndrome, nocturnal paresthesias, and sleep preferences. Binary logisticregression analysis was performed comparing participants with rare and frequentnocturnal paresthesias. Subanalyses for participants without carpal tunnelsyndrome under and over 21 years of age were performed on all factorssignificantly associated with subclinical compression neuropathy in the overallpopulation. Thirty-three percent of the study populationexperienced nocturnal paresthesias at least weekly. Increased body mass index( < .001) and sleeping with the wrist flexed( = .030) were associated with a higher frequency ofnocturnal paresthesias. Side sleeping was associated with less frequentnocturnal symptoms ( = .003). In participants without carpaltunnel syndrome, subgroup analysis illustrated a relationship between nocturnalparesthesias and wrist position. In participants with carpal tunnel syndrome,sleeping on the side had a significantly reduced frequency of nocturnalparesthesias. This study illustrates nocturnalparesthesias in people without history of carpal tunnel syndrome includingpeople younger than previously reported. In healthy patients with upperextremity subclinical compression neuropathy, sleep position modification may bea useful intervention to reduce the frequency of nocturnal symptoms prior todeveloping carpal tunnel syndrome.
