There are many diseases and especially so orthopaedic and neurological ones that have an obvious influence on the gait. In spite af that, there have been comparatively few attempts ta quantify gait disorders except within the orthopaedic discipline.
The quantification af gait is very useful in monitoring changes in the process af a gait disturbence, for instance ta evaluate the effects af a treatment af a patient. This may be the adjustment af a prostheses orta evaluate a surgical operation or rehabilitation procedures.
The gait quantification may also contribute to the task af making the diagnose af the disease.
In analysing the gait, the different factors which contribute ta the gait must be understood, their origin and in which way they are influenced by the disorder.
Valuable quantifications may be made in any hospital corridor with the simple expedient af a watch and a measuring tape. In combination with systematic visual inspection, measurements af velocity, stride frequency, and stride length may be used ta follow the course af a disease or ta test the effect af therapy.
With a more sophisticated equipment more information might be obtained, but the gait recording will be more difficult ta carry through and the load an the patient will increase.
There are two factors which are important for the understanding af gait dynamics, the progression and the postural control.
