Abstract
Background: Joint hypermobility is a connective tissue disorder that increases joint
range of motion. Plantar pressure and foot loading patterns may change with joint
hypermobility. We aimed to analyze static plantar pressure in young females with and
without joint hypermobility.
Methods: Joint laxity in 27 young females was assessed cross sectionally using the
Beighton and Horan Joint Mobility Index. Participants were divided into the hypermobility
(score, 4–9) and no hypermobility (score, 0–3) groups according to their scores. Static
plantar pressure and forces were recorded using a pedobarographic mat system.
Results: Higher peak pressures (P ¼ .01) and peak pressure gradients (P ¼ .025) were
observed in the nondominant foot in the hypermobility group. According to the
comparison of dominant and nondominant feet in each group, the hypermobility group
showed significantly higher peak pressures (P ¼ .046), peak pressure gradients (P ¼
.041), and total force values (P ¼ .028) in the nondominant foot.
Conclusions: The plantar pressure and loading patterns vary in young females with joint
hypermobility. Evaluation of plantar loading as an injury prevention tool in individuals
with joint hypermobility syndrome can be suggested
