Clinical Prediction

“This study identified that the combination of three of four predictors… increased the probability of marked improvement with foot orthoses from 25% to 78%. The preliminary clinical prediction rule identified in this study may assist clinical reasoning when considering foot orthoses prescription in individuals with PFPS.”Barton CJ, Menz HB, Crossley KM.

Regarding Vicenzino et al.: “Although this is a good preliminary clinical prediction rule, it was not developed from a purposely designed study. As a result, the analysis was inadequately powered for the number of variables entered into the regression equation, and evaluation was limited to patient demographics and foot morphometry.”Barton CJ, Menz HB, Crossley KM.

Regarding Sutlive et al.: “The study identified three predictors of >50% pain reduction after 3 wk (positive likelihood ratio > 2.0), including greater forefoot valgum, reduced first metatarsophalangeal joint (MTPJ) dorsiflexion, and reduced navicular drop (less pronated foot type). However, because of the poor interrater reliability reported for prediction variables (ICC = 0.25–0.55) and poor sensitivity values (0.13) of the non–weight-bearing forefoot and first MTPJ measurements, the findings have limited utility.”Barton CJ, Menz HB, Crossley KM.
