Adhesive capsulitis (AC), also known as frozen shoulder, is described as a painful restriction of the shoulder’s range of motion and about 3% of adults will develop the condition in their lifetime. In this study, researchers examined 148 adults, half of whom had AC, and identified a strong association between pain, anxiety, and sleep disturbance among those with frozen shoulder. The findings suggest that anxiety and disturbed sleep are common among patients with frozen shoulder and that conservative treatment, such as chiropractic care, aimed at reducing pain and improving range of motion may also improve sleep quality and anxiety levels in patients with the condition.
