Comparison of Core Muscle Asymmetry Using Spine Balance 3D in Patients With Arthroscopic Shoulder Surgery

Comparison of Core Muscle Asymmetry Using Spine Balance 3D in Patients With Arthroscopic Shoulder Surgery: A STROBE-compliant Cross-sectional Study

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.

Inclusion Criteria:

• neurological history or are taking related medications
• chronic headache or disease related to the inner ear
• cardiovascular disease that may affect balance ability or take related medications
• acute dizziness
• when performing other balance training
