The anatomical study of the major signal points of the court-type Thai traditional massage on legs and their effects on blood flow and skin temperature.

OBJECTIVE: This study aims to investigate the relationship between major signal points (MaSPs) of the lower extremities used in court-type Thai traditional massage (CTTM) and the corresponding underlying anatomical structures, as well as to determine the short-term changes in blood flow and skin temperature of volunteers experiencing CTTM. METHODS: MaSPs were identified and marked on cadavers before acrylic color was injected. The underlying structures marked with acrylic colors were observed and the anatomical structures were determined. Then, pressure was applied to each MaSP in human volunteers (lateral side of leg and medial side of leg) and blood flow on right dorsalis pedis artery was measured using duplex ultrasound while skin temperature changes were monitored using an infrared themographic camera. RESULTS: Short-term changes in the blood flow parameters, volume flow and average velocity, compared to baseline (P < 0.05), were observed on MaSP of the lower extremity, ML4. Changes in the peak systolic velocity of the area ML5 were also observed relative to baseline. The skin temperature of two different MaSPs on the lateral side of leg (LL4 and LL5) and four on the medial side of leg (ML2, ML3, ML4 and ML5) was significantly increased (P < 0.05) at 1 min after pressure application. CONCLUSION: This study established the clear correlation between the location of MaSP, as defined in CTTM, and the underlying anatomical structures. The effect of massage can stimulate skin blood flow because results showed increased skin temperature and blood flow characteristics. While these results were statistically significant, they may not be clinically relevant, as the present study focused on the immediate physiological effect of manipulation, rather than treatment effects. Thus, this study will serve as baseline data for further clinical studies in CTTM.

The Efficacy of Thai Herbal Prasaplai Formula for Treatment of Primary Dysmenorrhea: A Short-Term Randomized Controlled Trial.

This study aims to compare the efficacy of pain relief between a specific Thai herbal Prasaplai formula (PPF) and placebo in patients with primary dysmenorrhea. Forty women with primary dysmenorrhea symptoms were randomized into two groups. The experimental group received PPF capsules 1000 mg orally three times per day before meals for three days starting from the first day of menstruation. The placebo group received placebo as the same dose and time. Average pain intensity from the first day to the third day of cycle significantly decreased in both groups (p < 0.001), but with no statistically significant difference between groups. Using a pre- and posttreatment difference in NRS of at least 2, a greater proportion of patients in PPF group experienced pain relief compared to placebo during the first and second day of period. A greater proportion of PPF group also experienced no pain compared to the placebo group on day 1 and day 3 by using multidimensional scoring. The PPF demonstrates pain relief activity when used during menstruation in primary dysmenorrhea patients, with no adverse effects. However, further studies are needed in order to assess the value of PPF as a long-term prophylaxis for primary dysmenorrhea.
