Sitting study probes hidden link between tight hamstrings and spine shape

NCT ID NCT07682142

First seen Jul 02, 2026 · Last updated Jul 02, 2026

Summary

This observational study looks at whether tight hamstrings are related to the curve of the lower back in healthy adults who sit for more than six hours a day. Researchers measure hamstring flexibility and lumbar spine angle while participants sit upright, slumped, and leaning forward. The goal is to better understand how sitting posture and muscle tightness interact, which could eventually help improve comfort and prevent problems for people with desk jobs.
