Abstract
Objective: To determine the validity of Brody’s Navicular Drop Test (NDT), recorded using Foot Levelers’ Postural Stability Indicator (PSI) card, by correlating the change in the vertical height of the navicular bone in weightbearing and non-weightbearing positions.
Methods: Fifty-two volunteer subjects had their navicular positions documented using the PSI card system. Those values were then compared to “the more accurate values produced by radiography.”
Results: Of the 52 subjects measured radiographically, three showed an increase in navicular height, three demonstrated no change, and 46 demonstrated a decrease in height from non-weightbearing to weightbearing
positioning.
Discussion: Proper identification and application of orthotic intervention in patients with pes planus could prevent injury and improve performance within the kinetic chain of the spine and pelvis. In 1997, Foot Levelers announced the creation of the PSI, a simple, calibrated card to help chiropractors identify their patients’ risk factor for pronation.
Conclusion: The report determined that the ability of the NDT to reflect navicular position accurately was verified by comparison to the currently accepted procedure, X-ray analysis. Foot Levelers’ PSI card is a simple, reliable test for navicular position.
