Regional Associations Between Q-Angle and Plantar Loading in Active Young Adults

NCT07500597 | Completed

• 1 other identifier: HRÜ/25.20.26
• Study Type: observational
• Target: 92

Brief Summary

This observational study aims to examine the association between Q-angle and plantar loading characteristics in physically active young adults. Q-angle is a commonly used clinical measure of lower-extremity alignment, but its relationship with regional plantar loading during gait remains unclear. Participants will undergo bilateral Q-angle assessment and plantar pressure evaluation during walking. The study will investigate whether Q-angle is associated with specific plantar loading variables across different foot regions in active young adults.

Conditions

Q-angle; Plantar Loading Patterns

Keywords

Q angle; Plantar loading; Pedobarography; Lower extremity alignment; Foot biomechanics; Young adults

Outcome Measures

Physically active young adults

Eligibility Criteria

• Age: 18 Years - 27 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

Physically active young adults aged 18 years and older who were able to walk independently and had no current lower-extremity injury, neurological disorder, or other condition affecting gait or plantar loading. Participants underwent Q-angle measurement and plantar pressure assessment during walking.

You may qualify if:

• (1) being within the predefined young age range, (2) being physically active according to the IPAQ-SF based assessment, and (3) willingness to participate voluntarily.

You may not qualify if:

• (1) history of lower extremity injury within the previous 6 months, (2) previous lower extremity surgery, (3) known neurological or vestibular disorder affecting gait or balance, (4) current musculoskeletal pain in the spine or lower extremities during assessment, (5) diagnosed structural lower extremity deformity, and (6) inability to complete the assessment procedures independently.
