[[alternative]]Effects of Colorpuncture on Electrodermal Activities in Nurses with Shoulder Myofascial Pain

[[abstract]] 背景及目的：因為工作環境、及工作壓力等多方面因素，護理人員常常面臨肩頸及下背痛疼痛的困擾，其中以肌筋膜疼痛為最常見。傳統東方醫學認為，疼痛是因為身體正常運作的能量阻塞或停滯了，其反映了身體某部分受傷，而產生疼痛。過去研究顯示，穴位針灸及光能有效緩解肩頸疼痛。本研究即探討彩光針灸介入對於肌筋膜疼痛的成效。 材料及方法：本研究為前驅性之單組前後測實驗，實驗對象為南部某教學醫院護理人員，條件為持續二週以上在頸部或上背部有肌筋膜疼痛症狀，且有一個以上的激痛點者；收案人數16人；在受試者左右肩部肩中俞、肩外俞、肩井、巨骨等八個穴位，以藍色光各照射1分鐘。評量工具包括疼痛視覺類比量表(Visual Analogue Scale, VAS)、穴位能量儀彩光針灸筆 (Perlux P-117)。數據資料以SPSS 18.0 統計軟體進行分析。 結果：經過彩光針灸介入後，受試者於疼痛視覺類比量表下的疼痛分數由5.13 ± 2.09降為3.31 ± 1.44 (p < .05)，疼痛感降低了35%，顯示彩光針灸的介入能有效改善肌筋膜疼痛。經過彩光針灸介入後，受試者在商陽、少澤、厲兌、大敦、肩中俞、巨骨、肩外俞等穴位能量的穴位百分落差值(percentage difference, PD)有不同程度的上升或下降趨勢，但皆未達顯著差異。研究結果也發現，彩光針灸介入並未改變原有的陰陽平衡。 結論：彩光針灸為不具侵入性，使用安全，操作方便的一種替代療法，可改善肩頸部位之肌筋膜疼痛，推測此疼痛改善與穴位能量的提升有關；除此之外，肩部四穴點及十二井穴的相關性，與其循行的路線及對應的臟腑互為影響。[[abstract]] Background and Purpose: Due to the factors such as the working environment and work stress, nursing staffs are usually suffering from the shoulder and neck pain, which are commonly named as shoulder myofascial pain. From the viewpoint of Traditional Chinese Medicine, a pain happens when the energy flow of the body operation is blocked or stagnant and reflects the partial injury of the body. This study is to investigate the effectiveness of colorpuncture intervention for the shoulder myofascial pain. Materials and Methods: This is a pilot study by single-group pre-test. The 16 experiment objects were selected from hospital, who had symptoms of myofascial pain in the neck or upper back for more than two weeks and more than one trigger pain point. Objects was irradiated for 1 minute with blue light at the eight points of the Jianzhongshu (SI15), Jianwaishu (SI14), Jianjing (Gb21) and Jugu (LI16). The assessment tools are Visual Analogue Scale (VAS) and acupoint energy colorpuncture meter (Perlux P-117). Data was analyzed using SPSS 18.0 statistical software. Results: After the intervention of colorpuncture, the pain score under the VAS of the experiment objects is decreased from 5.13 ± 2.09 to 3.31 ± 1.44 (p < .05) and the pain feeling was reduced by 35%, which indicates the intervention of colorpuncture can effectively improve shoulder myofascial pain. The percentage difference (PD) of the electrodermal activities of the acupoints such as Shangyang (LI1), Shaoze (SI1), Lidui (St45), Dadun (Liv1), Jianzhongshu (SI15), Jianwaishu (SI14), Jianjing (Gb21) and Jugu (LI16) had different degrees of increase or decrease, all had not reached significant differences. This study also found that the intervention of colorpuncture does not change the yin-yang balance. Conclusion: Colorpuncture is an alternative therapy with effectiveness of not invasive, no side effects, safe and easy to use, which may improve shoulder myofascial pain. This study assumes that the pain improvement is related to the raise of acupoint energy. The correlation between the four acupoints of the shoulder and the twelve well-points affects the route and the corresponding organs
