Radiographic Head and Neck Positional Changes in Response to Low-Powered Prismatic Lenses

This document is a clinical trial registration entry on NIH's ClinicalTrials.gov registry describing a matched-pair observational study investigating the effects of low-powered prismatic lenses on head and neck positioning in patients with Postural Deficiency Syndrome. The study will evaluate changes using low-dose biplanar radiography before treatment and 15 minutes after lens application.

For healthcare providers and clinical investigators, this represents an informational registry record rather than a regulatory action. No compliance obligations or reporting deadlines are imposed. Institutions conducting or considering similar clinical research should monitor ClinicalTrials.gov for any protocol updates or results postings as the study progresses toward its April 2026 completion date.
