Effects of Custom 3D Printed Insoles and Short Foot Exercises in Pes Planus
The Effect of Custom 3D Printed Insoles and Short Foot Exercises on Foot Posture, Balance, and Gait Parameters in Individuals With Pes Planus
The primary purpose of this study is to evaluate the effects of combining custom 3D-printed medial arch-supported insoles with short foot exercises on foot posture, balance, and gait parameters in individuals with pes planus (flat feet). Furthermore, the study will investigate the impact of this combined intervention on secondary outcomes, including pain levels, health-related quality of life, and functional exercise capacity measured by the 6-Minute Walk Test.

Descripción detallada
Participants will be recruited through personal networks and social media platforms using a snowball sampling method. Potential candidates will be screened for pes planus in accordance with established literature protocols, utilizing the Foot Posture Index-6 (FPI-6) and the Navicular Drop Test.
Eligible individuals who meet the criteria for pes planus will undergo 3D foot scanning. Based on the obtained data, customized medial arch-supported insoles will be manufactured using 3D printing technology. Participants will be instructed to use these custom insoles in their daily lives for a total of 8 weeks. Concurrently, they will be assigned a daily short foot exercise (intrinsic muscle training) program. Each exercise repetition will involve a 5-second hold, and the entire protocol will be maintained for 8 weeks.
All clinical, functional, and biomechanical evaluations-including foot posture, dynamic balance, comprehensive gait and plantar pressure analysis (via the Zebris system), pain intensity, quality of life, and functional walking capacity-will be conducted at two time points: at baseline and at the end of the 8-week intervention period.
For statistical analysis, depending on the normality of data distribution, either a paired t-test or a Wilcoxon signed-rank test will be used to evaluate within-group changes between baseline and week 8. To determine the magnitude of the intervention effect, Cohen's d effect sizes for dependent measures will be calculated and reported alongside 95% confidence intervals.

¿Qué mide el estudio?
Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Foot Posture Index-6 (FPI-6)
Periodo de tiempo: Baseline and 8 Weeks
|
Assesses foot posture across 6 criteria. Total scores range from -12 (highly supinated) to +12 (highly pronated). |
Baseline and 8 Weeks
|
|
Navicular Drop Test (NDT)
Periodo de tiempo: Baseline and 8 Weeks
|
Assesses medial longitudinal arch height difference (in mm) between seated (non-weight bearing) and standing (weight bearing) positions. Higher values indicate increased pronation. |
Baseline and 8 Weeks
|
|
Modified Star Excursion Balance Test (MSEBT)
Periodo de tiempo: Baseline and 8 Weeks
|
Evaluates dynamic balance by measuring the maximum reach distance (in cm) in three directions: anterior, posteromedial, and posterolateral. |
Baseline and 8 Weeks
|
|
Spatiotemporal Gait and Plantar Pressure Parameters
Periodo de tiempo: Baseline and 8 Weeks
|
Evaluated using the Zebris system. Includes gait speed (m/s), cadence (steps/min), stride length (cm), stance percentage (%), and plantar pressure parameters (e.g., peak pressure, contact area). |
Baseline and 8 Weeks
|
Medidas de resultado secundarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Numeric Pain Rating Scale (NPRS)
Periodo de tiempo: Baseline and 8 Weeks
|
Assesses pain intensity on an 11-point scale ranging from 0 (no pain) to 10 (worst imaginable pain). |
Baseline and 8 Weeks
|
|
36-Item Short Form Health Survey (SF-36)
Periodo de tiempo: Baseline and 8 Weeks
|
Assesses health-related quality of life across 8 domains. Subscale scores are transformed to a 0 to 100 scale, where higher scores indicate better health status. |
Baseline and 8 Weeks
|
|
6-Minute Walk Test (6MWT) and Modified Borg Scale
Periodo de tiempo: Baseline and 8 Weeks
|
Evaluates functional capacity by measuring the total distance walked in 6 minutes (in meters). Perceived exertion is assessed before and after the test using the Modified Borg Scale (0-10 scale; higher scores indicate greater exertion). |
Baseline and 8 Weeks
