Comparison of Upper and Lower Cervical Muscle Strengths Between Subjects With and Without Forward Head Posture

Physical Therapy Korea, 2020
Background: Forward head posture (FHP) is common postural malalignment. FHP is described relatively extension to upper cervical and lower cervical is relatively flexion.

Comparison of the Pelvic Rotation Angle During Hip Lateral Rotation in the Standing and Prone Positions in Participants With and Without Tensor Fasciae Latae/Iliotibial Tract Tightness

Physical Therapy Korea
Background: Tensor fasciae latae (TFL) and iliotibial tract (ITB) tightness can pull the pelvis during hip lateral rotation (HLR), increasing pelvic rotation due to muscle tension.

Unsupervised machine learning for clustering forward head posture, protraction and retraction movement patterns based on craniocervical angle data in individuals with nonspecific neck pain

BMC Musculoskeletal Disorders
Objectives The traditional understanding of craniocervical alignment emphasizes specific anatomical landmarks. However, recent research has challenged the reliance on forward head posture as the primary diagnostic criterion for neck pain.

Relationship Between Craniovertebral Angle and Upper Trapezius Muscle Stiffness and Tone in Office Workers

Physical Therapy Korea
Background: With the increase of seated work, interest in forward head posture (FHP) has grown. Prolonged computer tasks with FHP have been considered a factor that increases the stiffness and tone of the upper trapezius (UT) muscle.
