Blood flow cuffs may boost back pain relief without heavy lifting
NCT ID NCT07576101
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether low-load exercise combined with blood flow restriction cuffs can reduce pain, improve hamstring strength, and lessen disability in people with chronic low back pain. About 44 adults aged 18–45 with pain lasting over 12 weeks will participate. The goal is to find a gentler treatment option that still provides meaningful relief.
