The efficacy and safety of Sipjeondaebo-tang in Korean patients with cold hypersensitivity in the hands and feet: a protocol for a pilot, randomized, double-blind, placebo-controlled, parallel-group clinical trial
Abstract
BackgroundCold hypersensitivity in the hands and feet (CHHF) is frequent in Asian countries including Korea. The quality of life can be degraded by the symptoms of CHHF. In particular, gynecological disorders such as menstrual pain, infertility, leucorrhea, and irregular bleeding may be related to CHHF. Sipjeondaebo-tang (SDT) is widely used in the treatment of various diseases including CHHF by balancing Yin and Yang, restoring the deterioration of physiological function, and improving immunity. However, the efficacy of SDT in the treatment of CHHF has not been assessed in clinical trials. Therefore, we aimed to investigate the feasibility of a full randomized clinical trial of SDT for the treatment of CHHF in Korean women through this trial.MethodsThis study will be a pilot, randomized, double-blind, two-arm, placebo-controlled, parallel-group, multicenter clinical trial. Women aged 19–59 years who present with CHHF will be recruited from five university hospitals. A total of 60 subjects will be randomly assigned to a treatment group (SDT) or a placebo group at a 1:1 ratio. The subjects will receive 3 g of either SDT or placebo three times daily for 8 weeks. The primary outcome measures will be the Visual Analogue Scale scores of CHHF. The secondary outcome measures will be changes in body temperature in both the hands and the feet as measured using a thermometer and the Korean version of the World Health Organization Quality of Life Scale Abbreviated…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 60 participants or records.
