Gait Analysis

The London Podiatry Centre has one of the most advanced dedicated podiatric gait facilities anywhere in the world today.

We have a whole website dedicated to our Gait Analysis services and facilities at

http://www.gaituk.com/

Whilst the Centre's 3D Vicon system is more commonly seen in university research facilities and special effect movie sets, it represents one of our most important diagnostic services.

Many injuries and conditions that are encountered occur as a consequence of an inherent abnormality in walking and it is only after diagnosing such deviations in normal "gait" that an accurate and highly specific treatment plan can be created.

Gait abnormalities occur in all manner of individuals but several key areas where we use our system extensively include:

  1. The technology is particularly used to diagnose the cause of an injury so that an effective evidence based treatment approach can be adopted.
  2. the analysis of children with walking abnormalities;
  3. complex injury management which has not responded to other treatments;
  4. professional and recreational athletes of all standards who are prone to injury.

Gait analysis can be divided into several components and these include:

  1. 2D analysis - where cameras are used to observe changes in walking without undertaking specific measurements
  2. Kinetic analysis - where up to 900 sensors are placed in each shoe so as to measure the forces, moments, pressures and loading times.
  3. 3D analysis - where advanced infra-red motion capture systems are used to recreate a digital model of the patient so that highly detailed quantitative data is obtained. Very few podiatric centres have this technology even though it is without doubt, the gold standard for analysing movement.

2D ANALYSIS

Two dimensional gait analysis using digital cameras and computerised software forms the mainstay of this assessment. The body is analysed comprehensively to shed light on the various imbalances which may be contributing towards the patients complaint. The information is cross referenced against the medical exam and biomechanical assessment and pressure analysis is often incorporated into this test.

Two dimensional gait analysis provides much useful data but it is ultimely far less accurate than advanced 3d technology. Furthermore, many of the imbalances and measurements that are obtain with 3d technology cannot be seen with 2d analysis

3D ANALYSIS

The Centre provides three dimensional analysis for those patients who require the most advanced form of gait investigation currently available. The assessment is ideal for patient who opt for a no compromise approach to gait analysis. It is invaluable in the assessment of professional athletes, paediatrics and for complex injury management. It provides base line information for future comparison and this can be invaluable for patients suffering from progressive disease such as rheumatoid arthritis and Parkinson's disease. The centre uses a state of the art Vicon motion capture system.

On the right is a video which shows how the centre managed to correct a patient's limp by means of a specialised ankle brace. 3D Vicon technology has been used to assess the patient. The yellow figure is the patient without the brace. Superimposed on the same video sequence is the same patient with the brace, this time in red. Note how the patient walks far more normally with the brace. This treatment has enhanced the patient's quality of life allowing her to walk pain-free for much longer distances!

KINETIC ANALYSIS

The London Podiatry Centre uses in-shoe pressure sensors to assess and measure force, pressure and timing. The system allows us to determine whether conditions of the foot relate to abnormalities in force and pressure. It also allows us to look at gait efficiency in a more general sense by optimising factors such as the centre of pressure, the force time relationship and other "kinetic" variables.
