Abstract:
Pupose: Foot orthoses (FOs) may be prescribed to control excessive foot pronation and have been implicated in enhancing postural stability. However, there is limited information relating to middle-age women who undertake physical activity. The purpose was to evaluate if wearing a standardised shoe containing a rigid, textured FOs had an effect on static postural stability in women with pronated feet. Method: A convenience sample of 22 asymptomatic female subjects was recruited (mean age: 51.5 ± 6.8years; mean height: 1.62 ± 0.06m; mean mass 70.1 ± 13.1Kg). All subjects were diagnosed with excessive foot pronation using the Foot Posture Index (mean score=6.3 ± 2.5). All subjects were fitted with standardised footwear and were randomly allocated into two groups. The control group (n=12) received shoes fitted with a prefabricated FOs with a medial rearfoot wedge of 40. The shoes of the intervention group (n=10) contained a similar prefabricated FOs with a medial rearfoot wedge of 40, and a dimpled texture applied to the surface. Postural stability was assessed using a Kistler force platform. Subjects stood on the force platform wearing the shoes and FOs with the feet placed either side of a T-shaped separator. Subjects had postural stability assessed with eyes open at baseline, then after 6 weeks of daily wear. Subjects were requested to wear the shoes for at least 6 hours a day in this time. For analysis of static postural stability 90% Confidence Intervals were determined for the changes in range of postural stability over a six week period. Results: Over 6 weeks, mean daily wear time was 4.7 ± 1.9 hours. The mean change in medial-lateral postural stability was 0.72mm (90% CI,-2.17 to 1.15 mm) and for the anterior-posterior postural stability was 2.53 mm (90% CI,-6.12 to 1.87 mm). Conclusions: There were no substantial effects on postural stability in this group of healthy middle-aged women when wearing shoes with a rigid textured FOs compared to a similar group who wore the shoes with a rigid FOs. Wearing hard textured FOs did not appear to improve their postural control.
