The aim of this study was to observe the effect of Embedding therapy on frozen shoulder. Methods: 57 patients with frozen shoulder were treated with Embedding therapy. It was performed once a day, once per a week. 15~20 Embedding thread were used in one time Embedding therapy. The total number of Embedding therapy was 10. Trapezius muscle including the Gyeonjeong (GB 21), Deltoid muscle including the Nosu (SI 10), Supraspinatus muscle including the Byeongpung (SI 12), Infraspinatus muscle including the Cheonjong (SI 11) and gokwon(SI 13), Lavator scapular muscle including the Gyeonjunsu (SI 15), Rhomboides major muscle including the Pungmun (BL 12), Rhomboides minor muscle including the Daejeo (BL 11) and Teres major muscle including the Gyeonjeong (SI 19). VAS scale, SPADI scale and ROM were compared between before and after treatment to evaluate the effect of Embedding therapy. Results: VAS scale decreased significantly (p=0.003). SPADI Scale decreased significantly (pain (p=0.006), disability(p=0.005)). ROM angle range increased significantly(flexion (p=0.005), extension(p=0.005), abduction(p=0.003), adduction(p=0.003), external rotation (p=0.005), internalrotation(p=0.005)). 29.8% patients were very much satisfied, 62.0% patients were satisfied and 8.0% patients were answered so so about Embedding therapy. Conclusion: The Embedding therapy could be effective to improve symptoms of frozen shoulder.
