Impact of foot pronation on postural stability: An observational study

OBJECTIVE: To investigate the effect of foot pronation on the postural stability through measuring the dynamic balance including overall stability index (OAI), anteroposterior stability index (APSI) and mediolateral stability index (MLSI). METHODS: Forty participants from both sexes were selected fr...

Description
Summary:OBJECTIVE: To investigate the effect of foot pronation on the postural stability through measuring the dynamic balance including overall stability index (OAI), anteroposterior stability index (APSI) and mediolateral stability index (MLSI). METHODS: Forty participants from both sexes were selected from the Faculty of Physical Therapy, Cairo University, with a mean age of 23.55 ± 1.74 years. Subjects were divided into two groups: group A (8 males and 12 females) with foot pronation, and group B (9 males and 11 females) with normal feet. The Navicular Drop Test (NDT) was used to determine if the feet were pronated and Biodex Balance System was used to assess dynamic balance at level 8 and level 4 for both groups. RESULTS: No significant difference was found in dynamic balance, including OAI, APSI and MLSI at stability level 8 ( p > 0.05) but, there was a significant difference at stability level 4 ( p < 0.05) between the two groups with lower stability in group A. CONCLUSION: Foot pronation affects the postural stability at stability level four and not affects stability level eight compared with those in the control group.
