Back brace showdown: jewett vs. spinomed – which one restricts movement more?
NCT ID NCT07170813
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests two types of hyperextension braces (Jewett and Spinomed) on 30 healthy adults aged 18-35. Researchers measure how much each brace limits spinal movement and affects posture during daily activities like standing and squatting. The goal is to provide clear data to help clinicians choose the right brace for patients with spinal injuries or posture problems.
