The Two Types

Digital gait-scanning technology is the only way to truly "see" how the foot functions as we walk. This is a major breakthrough in the identification and assessment of abnormal foot function, but of the two versions of this technology available, there is one which takes prescription orthoses to a new level.

All digital gaitscanning equipment comprises some type of pressure-sensitive pad which measures the forces within the foot as you stand on it and walk over it. The results from this scan, however, can be used in two different ways:

1.Subjective Digital Transfer - Data from the digital scan of the foot is interpreted by the practitioner, who then prescribes the orthotic;

2.Objective Digital Transfer - Data from the digital scan of the foot is sent directly to the laboratories where it is used to manufacture the orthotics. The prescription can be altered if required.

Pros and Cons

Both types allow us to "see" foot function, but only equipment of the Objective type can generate prescription orthoses directly from the digital data.

By using Objective Digitial Transfer, the continuity of data from capture through to production of the orthotic means subjectivity is eliminated from the prescription process. After all, it is gravity that causes abnormal foot shapes to alter foot function when we are weightbearing, so it makes sense that we capture the forces at work under the foot as we walk and use that data to directly calculate the most appropriate custom orthotic.

Whilst the human brain can identify and assess individual parts of the entire foot function sequence; it also interprets it, based on its' own training, ideas, beliefs and systems. Using a software package that can analyse the results and create the most effective control solution increases reliability and objectivity, something the world of custom orthotics desperately needs.

Does it really pay to go digital?

At present, there is only one digital gaitscanning package that operates using the Objective Digital Transfer method - TOG GaitScan.

Initially skeptical that technology could do better than years of specialist training, one of the world leaders in Functional Orthotic Therapy compared the effectiveness of orthoses "objectively" prescribed through the TOG GaitScan system against traditional subjective prescription methods on many of her patients.

She was amazed by the results - the objective prescription consistently provided the best device, regardless of the degree of correction required. Not only that, but the way in which the results are presented has proven a fantastic resource with which to educate her patients.

After experimenting and seeing the results for herself, she now knows that that the objective, laboratory-recommended prescription from TOG GaitScan provides an excellent device for the vast majority of patients first time around. In some cases, minor adjustments are required on the lab-based objective prescription, but this is typically required for very young or older patients and is something that is easy to adjust. She now uses the system exclusively in her own private practice, and presents seminars throughout Europe, on behalf of The Orthotic Group, to train others how to use the system.
