The purpose of this study was to investigate the effect of combined spinal stabilizing exercise for cervical alignment. For this study, 20 people who had abnormal cervical alignment were randomly divided into four group(n=5 per group) ; Con(control group), Mat exe(mat exercise group), Swiss exe(swiss ball exercise group), Mixed exe(mat and swiss ball exercise group). Spinal stabilizing exercise was performed to total 6 set a day, four times a week, during 5 weeks with method, which 10 seconds hold and 5 seconds relax, 10 times on 1 set and rest time 1 minute after each set ends. The results of this study were summarized as follows. 1. The change of Jackson's angle were showed significant difference in the group Mat exe, Swiss exe, Mixed exe especially, showed greatest statistically significant difference in the Mixed exe group compared to the control group(p<.001). 2. The change of ROM were showed significant difference in the group Mat exe, Swiss exe, Mixed exe especially, showed greatest statistically significant difference in the Mixed exe group compared to the control group(p<.001). In conclusion, experimental group performed spinal stabilizing exercise that cause ROM and Jackson's angle better coordinate flexor and extensor muscles of spine. Experimental group performed combined spinal stabilizing exercise can be effective for cervical alignment. Experimental group Mixed exe that performed mat and swiss ball exercises together shows significant difference and greatest effect as compared with other experimental group. Therefore, the combined spinal stabilizing exercise can be effective in rehabilitation to normal range of curvature of the cervical spine and in the increase of ROM.

Objective: To identify the asymmetric spinal stabilizing exercise (ASSE) postures that selectively activate the multifidus (Mu) relative to the erector spinae (ES) in patients with adolescent idiopathic scoliosis (AIS), thereby supporting the development of curve-specific exercise programs for three-dimensional spinal deformities.Methods: Surface electromyography recordings were obtained bilaterally from the ES and Mu muscles during ASSE postures. Signals were normalized to the maximal voluntary isometric contraction. The asymmetry ratio, Mu/ES ratio, and additional asymmetric contraction of the Mu were analyzed.Results: The study included 40 patients with AIS. The Mu demonstrated greater ipsilateral activation in the side-lying posture, whereas greater contralateral activation was observed during unilateral lower extremity lifting and combined upper?lower extremity lifting in the prone posture, as well as during combined upper?lower extremity lifting in the bird-dog posture. In the prone and bird-dog postures, the Mu/ES ratio exceeded 1.0, indicating relatively stronger Mu recruitment under rotational loading. Additional asymmetric contraction of the Mu was greatest in the side-lying posture (47%), with differences<15% in all other postures.Conclusion: ASSE induces posture-specific asymmetric activation of the paraspinal muscles in patients with AIS. Although the side-lying posture produced the largest asymmetry, this reflected increased ES activity for trunk elevation rather than true selective Mu contraction. In contrast, the prone and bird-dog postures demonstrated a greater Mu contribution relative to the ES under rotational loading. These findings suggest that ASSE can be adapted to target specific paraspinal muscle components: side lying for lateral bending and bird-dog variations to enhance rotational stability.
