There are great number of assumptions in this popular paradigm most of which have not been thoroughly tested. One component supposes that patterns of plantar pressure and associated hyperkeratosis lesions should be associated with distinct rearfoot mid foot first metatarsal and hallux kinematic patterns. Our aim was to investigate the extent to which this was true. Methods Twenty-seven subjects with planter pathological hyperkeratosis were recruited into one of two groups. Group 1 displayed pathological plantar hyperkeratosis only under metatarsal heads 2 3 and 4 n 14 . Group 2 displayed pathological plantar hyperkeratosis only under the 1st and 5th metatarsal heads n 13 . Foot kinematics were measured using reflective markers on the leg heel midfoot first metatarsal and hallux. Results The kinematic data failed to identify distinct differences between these two groups of subjects however there were several subtle generally 3 differences in kinematic data between these groups. Group 1 displayed a less everted heel a less abducted heel and a more plantarflexed heel compared to group 2 which is contrary to the Root paradigm. Conclusions There was some evidence of small differences between planter pathological hyperkeratosis groups. Nevertheless there was too much similarity between the kinematic data displayed in each group to classify them as distinct foot types as the current clinical paradigm proposes. Background Clinical diagnosis and orthotic management of mechanically related foot disorders is founded on a the generally
