Aims to investigate the relationship between pes planus (PP) with foot pain (FP) and performance in team sport athletes. Correlational research was adopted to reveal the relationship between PP with FP and performance. There were 84 athletes were involved in this research. Measurement of PP with footprint test (FT), FP with knee pain intensity-visual analogue scale (KPI-VAS) and performance with items 30m sprint (30ms), modified agility t-test (MATT), counter movement jump (CMJ), standing stock balance test (SSBT). We observed that FT-PP variable has a moderate negative correlation with FP-KPI-VAS (p = 0.003), which shows that PP significantly causes foot pain. In CMJ (p = 0.035) and SSBT (p = 0.004) there is a moderate negative correlation, which shows that the PP level reduced the level of power and balance. Meanwhile, there is a moderate positive correlation with 30mS (p < .001), and MATT (p < .001), which shows that the level of PP will reduce the level of running speed and agility. At the same time, FP-KPI-VAS had a small negative correlation with 30mS (p = 0.017), MATT (p = 0.017) and CMJ (p = 0.048). Finally, FP-KPI-VAS was found to have a large positive correlation with SSBT (p < .001). Thus, we confirm that PP is significantly correlated with FP and performance related to 30ms, MATT, CMJ, SSBT in team sports athletes.

Background: Flatfoot deformity is a common condition in children and teenagers that may increase the risk of knee, hip, and back pain. Most of the insoles suggested to treat flatfoot symptoms are not designed to adapt to foot temperature during walking, and they are either too soft to provide support or hard enough to be uncomfortable. Purpose: This study aims to develop an advanced solution to diagnose and treat flexible flatfoot (FFT) using infrared thermography measurements and a hybrid insole reinforced by nitinol (NiTiCu) smart-memory-alloy wires (SMAWs), this super-elastic alloy can return back to its pre-deformed shape when heated, which helps to reduce the local high-temperature points caused by the uneven pressure of FFT. This approach achieves a more uniform thermal distribution across the foot, which makes the hybrid insole more comfortable. Methods: The study involved 16 subjects, divided into two groups of eight flat-footed and eight normal. The procedure includes two parts, namely, designing a prototype insole with SMAW properties based on thermography measurement by using SolidWorks, and evaluating this design using Ansys. Second, a hybrid insole reinforced with SMAWs is customized for flatfoot subjects. The thermography measurement differences between the medial and lateral sides of the metatarsophalangeal line are compared for the normal and flatfoot groups before and after wearing the suggested design. Results: The results show that our approach safely diagnosed FFT and significantly improved the thermal distribution in FFT subjects by more than 80% after wearing the suggested design. A paired t-test reported significant (p-value > 0.001) thermal decreases in the high-temperature points after using the SMAW insole, which was closely approximated to the normal subjects. Conclusions: the SMAW-reinforced insole is comfortable and suitable for treating FFT deformity, and infrared thermography is an effective tool to evaluate FFT deformity.
