Abstract
Background: Gaining a comprehensive understanding of the plantar pressure distribution patterns in individuals with bilateral KOA is crucial for optimizing treatment strategies and improving patient outcomes.
Objective: Current this study aimed to compare the plantar pressure distribution patterns between men with bilateral KOA and those without KOA. By examining the differences in peak plantar pressure during walking, valuable insights can be gained regarding the biomechanical alterations associated with KOA.
Methods: 12 men diagnosed with bilateral KOA were recruited for the OA group (The sample size diagnosed via G*Power software). Their mean age was 59.48 ± 6.91 years, with an average weight of 77.13 ± 13.64 kg, height of 170.10 ± 11.88 cm, and BMI of 26.60 ± 2.13 kg/m2. Additionally, 12 healthy men were included as the control group, with a mean age of 55.45 ± 8.13 years, weight of 79.46 ± 13.64 kg, height of 172.12 ± 15.08 cm, and BMI of 26.94 ± 3.01 kg/m2. Peak plantar pressure OF 10 zones, was measured using RSscan Foot Scan. Statistical analysis was conducted using SPSS software version 21, employing an independent sample t-test with a significance level of 0.05 (P < 0.05).
Results: The analysis of plantar pressure distribution of 10 zones patterns revealed notable differences between the OA and healthy groups. Specifically, individuals in the KOA group exhibited lower peak plantar pressure in the hallux region, indicating reduced pressure exerted on the big toe during walking. Conversely, greater plantar pressure was observed in the medial heel region of the OA group, suggesting increased loading on the inner heel area. Additionally, elevated pressure was found in the midfoot and fourth metatarsal regions among individuals with KOA.
Conclusion: The findings indicate reduced pressure in the hallux and heightened pressure in the medial heel region, along with increased pressure in the midfoot and fourth metatarsal areas. These observed differences shed light on the biomechanical alterations associated with KOA and contribute to our understanding of the condition's impact on walking mechanics. Such insights are crucial for developing targeted interventions and optimizing treatment approaches for individuals with KOA.
