Plantar Pressure Distribution of Right and Left Foot in Bilateral Clubfoot Treated by Ponseti Method: A Correlation Analysis

Application of pedobarographic analysis in neglected congenital clubfoot patients following Ponseti treatment for recurrence prediction

“…Efforts to enhance cooperation, such as using toys, candies, or parental guidance, may have influenced the quality of testing data. However, the researchers involved in this study were experienced, and the testing process, validated by previous research [ 15 , 24 ], is considered mature and reliable, ensuring the quality of data collection. A primary limitation is that the study is observational, focusing on identifying prediction parameters.…”

“…An a priori power analysis (α = 0.05, β = 0.20) was conducted using GPower 3.0© software to determine the sample size. Based on an unpublished pilot study and a review of previous research [ [13] , [14] , [15] ], a sample size of 25 was initially estimated. Accounting for a potential dropout rate of 15%, a minimum of 30 participants needs to be included in the present study.…”

“…The pedobarographic data were collected using a Footscan® pressure plate [ 15 ] (RSscan International, Olen, Belgium, 2096 × 472 × 18 mm, with 16,384 resistive sensors arranged in a 256 × 64 matrix at a resolution of 2 sensors/cm 2 , data acquisition frequency of 125 Hz, and pressure range of 0–200 N/cm 2 ), which was connected to a computer via data processing box ( Fig. 3 A).…”

“…However, these methods pose challenges in achieving accurate and quantitative evaluation and are susceptible to subjective influences from examiners. Pedobarographic analysis, widely used in CCF evaluation [ 15 ], provides dynamic loading information during the roll-over process. Its advantage lies in its ability to detect residual or recurrent deformities that may not be visible to the naked eye, potentially aiding in the early identification of possible recurrence.…”
