Conditions

Asymmetric Limb Muscle Stiffness, Immobilization, Muscle Disorder, Postoperative Pain, Shoulder Injuries

Brief summary

This study is an observational cross-sectional study. Post-operative patients need an immobilization period for a certain period of time after surgery. Kinetic chain changes due to immobilization can affect the symmetry of the core muscle. Therefore, in this study, core muscle asymmetry (CMA) is measured using a whole body tilt device for inpatients who have undergone arthroscopic shoulder surgery. We would like to make a clinical suggestion for post-operative rehabilitation by identifying the characteristics of CMA according to the left or right site.

Interventions

DEVICEwhole body tilt device (Spine Balance 3D)

The symmetry of the deep muscle was evaluated using a whole body tilt device (Spine Balance 3D, Cyber Medic Co., Ltd., Korea). Spine Balance 3D can evaluate the maintenance strength and maximum strength of the core muscles, and perform a personalized core muscle training program based on the evaluated results.
