Influence of Pes Planus on Ankle Joint Mobility

Abstract

Background Individuals having proprioceptive problems associated with joint stiffness also tend to have ankle joint mobility disorders which can lead to injuries to lower extremities. Pes planus is the outcome of the midfoot arch collapsing. Since the midfoot absorbs shock those with pes planus are more susceptible to problems such as thumb valgus tendonitis plantar fasciitis pain in the metatarsals knee pain and lower back pain from extended walking all of which lower the quality of life.Objective The objective of this comparative study was to compare the ankle mobility of individuals with and without flat feet.Methodology The navicular drop test NDT was used for screening the dominant side. For the screening individuals aged between 18 and 24 years were chosen as subjects. A flat-foot has an excursion greater than 9 mm. The ankle joints range of motion RoM was measured using a Halo digital goniometer.Results There was a weak negative correlation between NDT and dorsiflexion DF of r 76 -.23 P.04 and eversion of r 76 -.19 P.09. There was a weak positive correlation between NDT and plantar flexion PF of r 76 .14 P.21 and inversion of r 76 .10 P.38. The research revealed a weak correlation between the ankle joints plantar flexion inversion or eversion.Conclusion A weak correlation was found between the extent of pes planus and anklersquos range of motion.
