Efficacy of Ya-Tha-Pra-Sen in Relieving Frozen Shoulder Pain

Abstract

This preliminary quasi-experimental study focuses on the efficiency of Ya-Tha-Pra-Sen toward the frozen shoulder patients of Kaeng Sopha Health Promotion Center, Kaeng Sopha Sub- District, Wang Thong District, Phitsanulok. Subjects of this study were 28 volunteers who have used Ya-Tha-Pra-Sen two times per day for 14 days. The assessment was collected before and after the drug testing with data analysis form of the Visual Analog Scale (VAS) pain level, and the evaluation of shoulder range of motion was performed with the Thai Arthrometric Navigator Scale (TAN Scale). Data were analyzed through percentage, mean, standard deviation, and paired sample t-test statistics.

These results demonstrated that the pain level after the use of Ya-Tha-Pra-Sen was significantly alleviated (P-Value < 0.001), and the range of motion in the shoulder joint in the arms raising position and the arm extending position was significantly increased (P-Value < 0.001). However, there is a mild adverse effect on drug safety. The results indicate that Ya-Tha-Pra-Sen from the Phra Narai textbook is effective in relieving shoulder pain, and also improving the capability of arms, and active the degree of the shoulder joint rotation.
