简要总结
This study aims to investigate the effects of pes planus deformity on gait spatiotemporal parameters and pelvic kinematics during walking on different inclines. Participants will include healthy adults aged 18-35 years with flexible bilateral pes planus and normal body mass index. Pes planus severity will be evaluated using the Jack's toe-raise test and the navicular drop test. Gait parameters such as walking speed, cadence, stride length, stance and swing phase percentages, gait cycle duration, as well as pelvic tilt, obliquity, and rotation symmetry will be measured using the BTS-G wireless sensor system. Assessments will be performed on both flat and inclined treadmill conditions. The findings are expected to provide new insights into the biomechanical adaptations of pes planus during walking and contribute to the development of an individualized rehabilitation protocol.
详细描述
This study will evaluate the effects of pes planus deformity on gait spatiotemporal parameters and pelvic kinematics during walking on flat and inclined surfaces. Flexible pes planus will be confirmed with Jack's toe-raise test, and severity will be assessed using the navicular drop test.
Healthy adults aged 18-35 years with bilateral flexible pes planus and normal BMI will be included. Exclusion criteria are lower extremity injury or surgery in the last 6 months, chronic ankle instability, other musculoskeletal disorders, or orthotic use.
Gait will be assessed with the BTS-G wireless sensor system, recording speed, cadence, stride length, stance and swing phase percentages, gait cycle duration, pelvic tilt, obliquity, and rotation symmetry. Participants will walk in standard sports shoes on level and inclined treadmill conditions. Data will be analyzed to determine biomechanical differences across surfaces.
The findings may provide insights into how pes planus influences gait and contributes to rehabilitation and footwear strategies.

结局指标
主要结局
Gait Speed (Level vs. Inclined Walking)
时间窗: up to 6 months
Self-selected walking speed (m/s) measured during 20-m trials under level and inclined treadmill conditions using the BTS-G wireless sensor (L4-L5 placement). Between-group (pes planus vs control) and within-condition comparisons.
Cadence
时间窗: up to 6 months
Steps per minute captured by BTS-G during level and inclined walking; between-group and within-condition comparisons.Unit of Measure: steps/min.
Stride Length
时间窗: up to 6 months
Stride length (cm) during level and inclined walking recorded via BTS-G; between-group and within-condition comparisons.
Stance and Swing Phase Percentages
时间窗: up to 6 months
Percentage of the gait cycle spent in stance and swing (%) under level and inclined conditions using BTS-G; between-group and within-condition comparisons.
Pelvic Kinematics-pelvic tilt
时间窗: up to 6 months
Pelvic tilt recorded with BTS-G sensor across barefoot, 2 cm heel, and 6 cm heel conditions. It will be recorded as a degree.
