“…The core result was that the index of load of the midfoot was the only cluster which showed a significant difference between healthy volunteers, AA and TTC. [10] This study builds on this result. Within the index of load for the midfoot the maximal force (MF) was the strongest contributor to the net effect.…”

“…In an earlier study this number was reduced to 27 parameters (9 each for hindfoot, midfoot, and forefoot). [10] This reduction was crucial to make the data amenable to statistical analysis and for an interpretation of results. The remaining variables were aggregated into clusters, thus creating an index of rollover (representing all parameters of time) and an index of load (representing all parameters of load) for each area.…”

“…In the past, other studies have also tried to identify correlations between AOFAS score and pedobarographic parameters. In a study comparing ankle- and tibiotalocalcaneal arthrodesis to healthy participants we also found a correlation between different midfoot load parameters (MF, PP, integrals of MF and PP) summarized as “midfoot index of load” and the AOFAS-score [9]. Schuh found a significant correlation between the AOFAS score and the loading parameters of the medial midfoot after surgery of posterior tibial tendon dysfunction [23].…”

BackgroundPedobarography offers dynamic information about the foot, but the interpretation of its large data is challenging. In a prior study it was shown that attention can be restricted to pedobarographic midfoot load data. We aim to verify this observation in ankle osteoarthritic and contralateral feet.MethodsWe assessed both feet of 120 patients with end-stage ankle osteoarthritis (OA) and 35 healthy volunteers with AOFAS-score and dynamic pedobarography in barefoot condition. We introduce a new parameter, the Relative Midfoot Index (RMI), representing the depth of the midfoot weighted by the maximal force (MF) in the hindfoot and forefoot. Main outcome measures were the RMI, MF and contact times in the hindfoot, midfoot and forefoot. Ankle OA, contralateral and healthy feet were compared with ANOVA.ResultsThe RMI was significantly smaller in OA feet (0.65 ± 0.19) and contralateral feet (0.69 ± 0.15) than in healthy feet (0.84 ± 0.08, p < 0.0001). There was no significant difference between OA and contralateral feet. The RMI showed a correlation of 0.48 with the AOFAS score. Contralateral and OA feet were significantly different from healthy feet (p < 0.001) in all parameters except the hindfoot MF. An RMI <0.8 showed a positive predictive value of 80% and sensitivity of 78% for being unhealthy.ConclusionThe RMI assists the interpretation of pedobarographic parameters and provides a user-friendly indicator for unhealthy foot conditions with a cut-off value of 0.8. The contralateral feet of ankle OA patients differed significantly from healthy feet and are therefore not suitable as control group.Level of Evidence: 3 case control study
