Study population: young adults with forward head posture

Brief summary: The purpose of this study will be to investigate:

1. Relationship between forward head posture and hamstring tightness in young adults
2. The gender specific effect (female versus male) on the relationship between forward head posture and hamstring tightness in young adults

Detailed description: Forward head posture imposes approximately 3.6 times more pressure on the neck than proper posture, and the prolonged burden of supporting the increased head weight can potentially cause neck pain, fatigue, and chronic musculoskeletal disorders. Hamstring tightness can cause posterior pelvic tilt, which leads to decreased lordosis of lumbar spine and resulting in LBP. Hamstring tightness can contribute to various issues, including muscle strains,loss of lumbar spine curvature, sacroiliac joint disorders, and plantar fasciitis. These problems primarily arise due to misalignment of the body and imbalanced force distribution between muscles and joints. Hamstring and sub-occipital muscles are connected by a neural system and sub-occipital muscles pass through the dura mater. this is called superficial back line (SBL), which connects the lower extremities, trunk, neck, and head protects the body's entire posterior surface and provides an important function of up-righting the body. There is still lack of research work about the relationship between FHP and hamstring muscle tightness and the gender-specific effect (female versus male) on the relationship between FHP and hamstring tightness in young adults.
