Paul Graham has been using plantar pressure analysis as part of his clinical practice since first purchasing an Fscan Mat and in-shoe system in 1998. It was a steep learning curve to understand the information behind the pretty colours and what they mean. At the time, this form of analysis was in its infancy in Australia, and the only way of gaining an appreciable understanding of what the data represented and how it could be used in clinical practice was gained through regular email and phone contact with a number of podiatrists in the U.S. who had been using the Fscan system for many years.
The most well-known of these practitioners is Dr Howard Dannenberg and through this relationship Paul grew to understand the relationship of sagittal plane movement and the importance of how the foot has a significant effect on the rest of the body. In fact Paul’s foundational knowledge of recording, data management and analysis came through Howard’s leadership and the plantar pressure case studies that were shared. This knowledge base was further augmented when Dr Bruce Williams DPM, a protégé of Howard’s training, visited Australia in 2004 and stayed with Paul in Geelong, working with and training him at Total Care Podiatry. In 2005, Paul was invited to Latrobe University to present on his clinical use of plantar pressure in orthotic correction design and prescription.
At this point, Paul was combining evidence-based examination and video gait assessment with plantar pressure analysis and, through this orthotic manufacture. The issue was that each part of the assessment used different equipment. In 2006 Paul moved to the Milletrex system, (forerunner of the Freestep software and Sensormedica hardware) as this combined all aspects of the diagnostic and manufacturing process.
In late 2010, the Freestep software program was presented and the engineers in Italy were keen to make it the best on the market. Since then there have been regular updates to make the program more user-friendly and the data presentation more valuable and easy to understand.
In 2017 Paul is working with Scott Sorenson of BodyTech Systems and the Italian Freestep software developers to enhance the analysis further so that areas of dysfunction and asymmetry are easily noted and measured. This will be valuable for both the initial assessment and to easily chart improvement at review appointments. This continued refinement and development, makes Freestep a very valuable clinical tool.
Plantar pressure analysis can only grow in significance as it shows objective data that the eye cannot see. This is now even more important with the discovery that vertical force, that we describe as pressure, is what causes the overloading that results in tissue damage, rather than any angular anomaly such as an inverted heel or lowering of the medial longitudinal arch.
Using Freestep enables Paul to chart a patient’s improvement effectively and efficiently each visit by simply having them walk over the mat or run on the treadmill and comparing it to the previous visit; all within five minutes. This is then a record of the patient’s progress; valuable, not only to the treating clinician, but also to any third party who may be paying for the treatment.
Video gait assessment is very, very helpful in understanding the biomechanics of the body in motion and should be used in conjunction with plantar pressure analysis; however Paul’s clinical use of plantar pressure analysis has led him to the conclusion that it is superior to video assessment in providing consistent meaningful results and in ease and speed of analysis.
