Abstract
Background Ao-dake-humi is a traditional Japanese bamboo foot stimulator consisting of a half-pipe-shaped step made of bamboo used to stimulate the foot by stepping on it, and is commonly used to promote general health among the elderly in Japan. However, its efficacy has not been reported in the scientific literature. This study was performed to investigate the role of ao-dake-humi focusing on lower urinary tract symptoms (LUTS), constipation, and hypersensitivity to cold (HC).MethodsParticipants with LUTS, constipation, or HC were enrolled in this study. Ao-dake-humi was used twice a day for 28 days. Before and 28 days after starting ao-dake-humi use, international prostate symptom score (IPSS), quality-of-life (QoL) score, and overactive bladder symptom score (OABSS) were measured to evaluate the efficacy of ao-dake-humi on LUTS. To evaluate the objective efficacy of ao-dake-humi on LUTS, a frequency-volume chart (FVC) was plotted in LUTS patients for 3 days. A visual analogue scale (VAS) was used to evaluate the efficacy of ao-dake-humi on constipation (VAS-constipation) and HC (VAS-HC) in the participants with constipation or HC.ResultsA total of 24 participants were enrolled in this study. Twenty-one participants had LUTS, 11 had constipation, and 17 participants had HC. IPSS, especially storage-subscore, QoL score and OABSS, decreased significantly after use of ao-dake-humi. The use of ao-dake-humi increased maximal bladder capacity, resulting in a significant decrease in urinary frequency as determined from the FVC. In accordance with the results of VAS-constipation and VAS-HC, both constipation and HC were significantly relieved after ao-dake-humi use.ConclusionThe results of this prospective pilot study indicated that ao-dake-humi is safe and has therapeutic efficacy in cases of LUTS, constipation and HC. The possibility of using ao-dake-humi as physical neuromodulation therapy was shown in the management of LUTS, constipation and HC.Trial registration UMIN000019333 (UMIN-CTR, Registered October-15-2015) retrospectively registered.

We reported the importance of simultaneous management of lower urinary tract symptoms (LUTS), constipation and hypersensitivity to cold (HC) considering interaction among pelvic organs and skin [2] (Fig. 1a)
Constipation and HC were evaluated according to selfdescription
Summary
This study was conducted between July 2013 and October 2015. The trial registration number is UMIN000019333 (UMIN-CTR, registration date is 15th Oct. 2015). In the process of the previous management of LUTS before enrolling this trial, urinary tract infection and cancer including prostate cancer had already excluded. Participants could continue to take medication for LUTS and constipation to maintain the same condition before and after the study. The participants were not permitted to start or stop any intervention for LUTS, constipation or HC during the study. Before and 28 days after ao-dake-humi, international prostate symptom score (IPSS), quality-of-life (QoL) score, and overactive bladder symptom score (OABSS) were measured for evaluation of efficacy of ao-dakehumi on LUTS. Visual analogue scale (VAS) was used to evaluate the efficacy of ao-dake-humi on constipation (VAS-constipation) and HC (VAS-HC) in the enrolled participants with constipation or HC. The FVC on 3 continuous days was recorded in all of the enrolled LUTS participants before and 28 days after starting ao-dake-humi use. The changes before and after aodake-humi were analysed using the paired t test
