“…When compared with our previous study, the sagittal forefoot dorsiflexion decreased throughout the entire barefoot trial but not enough to show clinical significance [20]. However, in our current study, there was no significant difference between the HAFO and barefoot trials.…”

“…During the initial visit of our study, the use of the HAFO produced an increase in ankle dorsiflexion and a decrease in forefoot sagittal motion [20]. Romkes et al [23] also found an immediate improvement after HAFO use; there was a reduced ankle plantarflexion during the swing phase (–26.7° BF and 0.7° HAFO) and toe off (–17.1° BF and 2.7° HAFO) and increased step and stride length.…”

“…The system used square sensors (∼1.5 cm × 1.5 cm) placed on the foot to register movement, and all sensors were attached via a cord to a signal processing box. The marker configuration used was a 6SF model previously used to measure changes in foot motion in normal pediatric subjects . The external sensors were placed on the foot to track motions of the tibia, calcaneus, cuboid, navicular, 1st metatarsal, and hallux.…”

We compared the ankle joint and foot segment kinematics of pediatric cerebral palsy (CP) participants walking with and without orthoses. A six segment foot model (6SF) was used to track foot motion. Holes were cut in the study orthoses so that electromagnetic markers could be directly placed on the skin. The Hinged Ankle Foot Orthoses (HAFO) allowed a significant increase in ankle dorsiflexion as compared to the barefoot condition during gait, but significantly constrained sagittal forefoot motion and forefoot sagittal range of motion (ROM) (p < 0.01), which may be detrimental. The Solid Ankle Foot Orthoses (SAFO) constrained forefoot ROM as compared to barefoot gait (p < 0.01). The 6SF model did not confirm that the SAFO can control excessive plantarflexion for those with severe plantarflexor spasticity. The supramalleolar orthosis (SMO) significantly (p < 0.01) constrained forefoot ROM as compared to barefoot gait at the beginning and end of the stance phase, which could be detrimental. The SMO had no effects observed in the coronal plane.

“…However, most literature describing normal foot motion is limited by the small number of segments of the foot investigated, small sample size, or both. The most valid kinematic data requires direct measurement of bone motion [ 8 ] or imaging of individual bones [ 9 , 10 ]. However these inevitably suffer from a lack of generalisability.…”

BackgroundUnderstanding motion in the normal healthy foot is a prerequisite for understanding the effects of pathology and thereafter setting targets for interventions. Quality foot kinematic data from healthy feet will also assist the development of high quality and research based clinical models of foot biomechanics. To address gaps in the current literature we aimed to describe 3D foot kinematics using a 5 segment foot model in a population of 100 pain free individuals.MethodsKinematics of the leg, calcaneus, midfoot, medial and lateral forefoot and hallux were measured in 100 self reported healthy and pain free individuals during walking. Descriptive statistics were used to characterise foot movements. Contributions from different foot segments to the total motion in each plane were also derived to explore functional roles of different parts of the foot.ResultsFoot segments demonstrated greatest motion in the sagittal plane, but large ranges of movement in all planes. All foot segments demonstrated movement throughout gait, though least motion was observed between the midfoot and calcaneus. There was inconsistent evidence of movement coupling between joints. There were clear differences in motion data compared to foot segment models reported in the literature.ConclusionsThe data reveal the foot is a multiarticular structure, movements are complex, show incomplete evidence of coupling, and vary person to person. The data provide a useful reference data set against which future experimental data can be compared and may provide the basis for conceptual models of foot function based on data rather than anecdotal observations.
