척추 및 골반 변형을 교정하기 위한 맞춤형 운동 재활 시스템 개발 = Development of a Personalized Exercise Rehabilitation System for Correction of Spine and Pelvic Deformity

다국어 초록 (Multilingual Abstract)

Spine and pelvis plays a very important role to keep balance and correct posture. However, congenital or acquired spine and pelvic deformity may cause low back pain, scoliosis, pelvic asymmetry, and leg length discrepancy, and it affect negatively on postural balance. Although, with the increase in demand generalized rehabilitation exercise devices for solving problems are being developed, personalized exercise rehabilitation system to provide 3-dimensional personalized exercise based on the results of clinical evaluation of patients has not been studied until now.
Therefore, in this study, biomechanical characteristics of patients with spine and pelvic deformity were evaluated by measuring pelvic inclination angle, body and planter pressure, and trunk muscle activities in static and dynamic sitting conditions. And then, based on the results of clinical evaluation, personalized exercise rehabilitation system was developed to treat spine and pelvic deformity and improve postural imbalance. In addition, clinical test for verifying the effectiveness of manufactured system was conducted by comparing differences in postural balance patterns between before and after exercising.
In the first study, postural balance patterns of patients with spine deformity were evaluated by assessing the inclination angles, body and plantar pressure, and trunk muscle activities in static and dynamic sitting condition. From the results of this study, it was confirmed that spine deformity cause postural imbalance with asymmetrical pelvic inclination angle, pressure distribution, and muscle activation patterns.
In the second study, postural balance patterns of patients with spine and pelvic deformity were assessed by comparing the differences in inclination angles, body pressures, and trunk muscle activities among control group, patients with spine deformity group, patients with pelvic deformity group, and patients with spine and pelvic deformity group. It was concluded that asymmetrical postural balance has been associated with occurred area on spine and pelvic deformity.
In the third study, personalized exercise rehabilitation system was manufactured based on the results in the clinical evaluation of patients with spine and pelvic deformity. This system was designed to provide the axial elongation, derotation, deflexion, facilitation, and stabilization for efficient exercise. To evaluate the clinical effectiveness of this system, changes in the inclination angles, body pressure distribution, and muscle activities were compared between initial, middle, and final test after performing personalized exercise. The results of this study showed that asymmetrical postural balance was improved as well as weak muscle was also strengthen relatively after performing exercise program using personalized exercise rehabilitation system. This study suggests that personalized exercise rehabilitation system and exercise program may help to prevent progression of deformity and recover abnormal postural balance of patients with spine and pelvic deformity.
