Cross-sectional analytical study. Adhesive capsulitis (AC) is a long-standing condition with varying extents of disability seen among patients. The role of postural manifestations and contractile tissue involvement in this condition is poorly understood and yet to be explored. This study aimed to analyze if individuals with adhesive capsulitis demonstrated the characteristics of an upper crossed syndrome (UCS) postural manifestation and whether or not its presence affected the extent of disability experienced by this population. Sixty-five individuals with AC were assessed for the presence of UCS. Scapular muscle strength and length alterations, forward head posture (FHP), and disability were assessed and compared between those with and without UCS. Paired T test and an independent T test were utilized to compare means within and between these groups, respectively, while non-parametric measures were utilized for their skewed counterparts. Phi coefficient (φ) was used to determine the strength of association between the descriptive patient characteristics. The correlation between symptom duration and degree of postural involvement was analyzed using Pearson's correlation coefficient. 43.1% of the study population demonstrated UCS and 80% FHP with a significant negative correlation between Cranio Vertebral Angle and chronicity of AC (r = −0.27). Individuals with AC demonstrated significantly decreased scapular muscle strength (p =
