Transcutaneous electric nerve stimulation in restless leg syndrome with cirrhosis: a pilot study.

BACKGROUND

The study aimed to evaluate the effect of transcutaneous electric nerve stimulation (TENS) on restless leg syndrome (RLS) severity, sleep, quality of life, anxiety, and depression in liver cirrhosis patients.

RESEARCH DESIGN AND

METHODS

This was single-arm, open label, pilot study. Cirrhosis patients with RLS were evaluated with International RLS Score (IRLSS, scored 0-40 for severity) at baseline and 1, 2, 4, 6 weeks. Sleep quality, quality of life, depression, and anxiety were assessed using Pittsburg Sleep Quality Index (PSQI, 0-21 with poor sleep), RLS Quality of Life Questionnaire (RLSQoL, 18 items, 13 scored 0-15, higher score - good quality of life), Hamilton Depression Rating Scale (HAM-D, scored 0-53 with increasing depression), and Hamilton Anxiety Rating Scale (HAM-A, scored 0 to 56 with increasing anxiety) at baseline and 4 weeks of TENS.

RESULTS

Twenty-five patients (mean age 52 ± 9.1 years, 52% females) received TENS. Mean IRLSS improved from 22.28 ± 6.724 to 6.08 ± 5.590, 7.48 ± 7.206, 8.56 ± 6.715, 11.76 ± 5.456 after 1, 2, 4, and 6 weeks. Baseline sleep quality, quality of life, anxiety, and depression scores (9.6 ± 5.1, 73 ± 20.7, 25.4 ± 11.7, 19.2 ± 10.6) improved after 4 weeks of TENS (4.7 ± 3, 94.9 ± 12.5, 8.9 ± 5.7, 7.5 ± 5).

CONCLUSION

Transcutaneous Electric Nerve Stimulation improved RLS symptoms, sleep quality, anxiety, depression, and overall quality of life in cirrhosis patients.
