HAMSTRING TIGHTNESS AND LUMBAR LORDOSIS ANGLE ACROSS FUNCTIONAL SITTING POSTURES

Sponsor: Cairo University

View on ClinicalTrials.gov

Summary

The goal of this observational study is to learn about the relationship between hamstring tightness and the lumbar lordosis angle in sedentary adults across different sitting postures. The main question it aims to answer is: Is hamstring tightness related to the lumbar lordosis angle across three functional sitting postures (upright, slumped, and forward-leaning)? It also asks whether hamstring tightness differs between men and women, whether it differs between the dominant and non-dominant leg, and whether the lumbar lordosis angle differs between men and women across the three postures. Participants will have their hamstring tightness measured with the Active Knee Extension test and their lumbar lordosis angle measured with a bubble inclinometer while sitting in each of the three postures.

Official title: CORRELATION BETWEEN HAMSTRING TIGHTNESS AND LUMBAR LORDOSIS ANGLE ACROSS FUNCTIONAL SITTING POSTURES IN SEDENTARY ADULTS.

Hamstring tightness and lumbar lordosis assessment

Hamstring tightness measured bilaterally with the Active Knee Extension test (digital goniometer) and lumbar lordosis angle (T12-S2) measured with a bubble inclinometer across three functional sitting postures. No therapeutic intervention is administered; these are observational measurements only.
