Purpose: Continuous use of a smartphone increases the angle of forward bending of the user’s cervical vertebrae, causing pain in the shoulders and back, including the thorax, lumbar region, and vertebrae. Although there are many studies on changes in the cervical spine due to smartphone usage, the changes in the shoulders, thoracolumbar spine, and pelvic have rarely been compared. The purpose of this study is to investigate the change in the spinal segments, shoulders, and pelvic when using a smartphone with both hands while in the standing position. Methods: This study was conducted on 35 adults in their twenties. The selection criteria for the subjects were limited to those in a similar age group, thus excluding posture differences according to age, and to those who did not have specific diseases or pain in the spinal and musculoskeletal system for 12 months prior to the study. In this study, we used a 3D spinal diagnostic imaging system (Back Mapper, Frickenhausen) to compare the changing conditions in each vertebral segment before and during smartphone usage with both hands while in the standing position. Posture differences according to smartphone usage were compared using the paired t-test for the motion of each spinal segment. Results: This study showed that the thoracic and lumbar angle increased posteriorly during smartphone usage (p<0.05). In addition, the anterior rotation angle of the shoulder bone significantly increased, but no significant difference occurred in the pelvic region. Conclusion: Based on the results of this study, smartphone usage with both hands while in the standing position showed that the spine, as a whole, forms a kyphotic curve. Therefore, we propose to present a postural guideline for correct smartphone usage, considering the change in each vertebral segment.

학회를 방문 해 주셔서 감사 드립니다. 대한고유수용성신경근촉진법학회는 오래 전 부터 외국 강사를 초빙 하여 임상적지식을 보급하고, 학술적으로 연구 해 오든 중 1995년 11월11일 제주도에서 창립총회를 했습니다.
고유수용성신경근 촉진법(proprioceptive neuromuscular facilitation, PNF )은 물리치료사인 Margaret Knott 와 의사이며 신경생리학자인 Herman Kabat (1946-1951 )에 의해 고안 되었습니다. PNF 에는 환자 치료를 위한 철학과 치료기법을 포함하고 있습니다. 치료기법에는 운동학습, 운동조절, 운동행동, 생역학, 인지 등등을 고려한 중추신경계손상자를 위한 접근법과 근력강화, 관절가동범위증가, 지구력의증가, 통증 조절등의 정형외과 계열의 환자를 위한 모든 치료법을 포함하고 있습니다
기능 즉 인체의 모든 기관계의 조화로운 통합으로 이루어지는 기능을 향상 발전 시킬 수 있는 통합적 접근 기법입니다.
최근 WHO(2001)가 제정한 ICF( international classification of function )를 충족 할 수 있는 유일한 치료 접근법이라 할 수 있습니다. 많은 학술 연구자, 임상가들이 학회 발전에 참여하여 학문적, 임상적 풍요로움이 넘치는 학회가 될 수 있기를 기원합니다
