Unified Summary ADPlot

Unified Summary ADplots may be used in everyday clinical practice.

Each Unified Summary ADplot can be considered as a gait graph pathology map.

Figure 1. Unified Summary ADplots for the Knee gait graphs in the sagittal and frontal planes for three groups of patients with Cerebral palsy (Hemiplegics, Diplegics Quadriplegics)

This graph is named Unified because the indexes of the Right and Left gait curves are unified resulting in a single Mean Deviation Index for the group and a Standard Deviation that represents the dispersion of the indexes of both limbs of the subjects with the specific pathology.

In the following lines it will be explained the importance of this unification.

The mean GGAI and the unified GGDI values of a specific group of patients, indicate where the mean pathology values for the specific group are located. The SD bars around the mean values can be considered as the lower and upper limits of the ranges that define the moderate gait graph pathology area.

Using this map, the clinicians can quantitatively evaluate a patient’s gait report graphs, in comparison to the respective pathology group. Thus, mild pathology involvement is documented if the patient’s GGAI and GGDI values are in the lower left end of the ADplot below the range of the moderate gait graph pathology area and closer to normal (gray area). Contrarily severe pathology involvement is considered when the patient’s GGAI and GGDI values are located upper and right than the upper limits of the moderate gait graph pathology area.

The creation of these maps for various groups with pathology, may help even clinicians without deep knowledge of gait analysis to directly evaluate the severity of the the gait report graphs for the specific pathology making it an excellent educational, communication and research tool.

Example: CP Diplegia ADPlot Pathology Map.

The yellow Boxes define the Moderate Diplegic Pathology area.

This form of ADplot is enhancing gait analysis evaluation by providing the following very useful information for each gait graph.

1) Right and Left Mean Deviation index values (Top Left values on each graph)

2) Mean Asymmetry index values ( Bottom Right values on each grpah)

3) Consistency Evaluation ( Right = Blue area, Left = Red area - larger area => larger variability)

4) Subject Pathology Evaluation (Yellow Area = Moderate , if closer to zero = Mild & if above and right = Heavy)

It is very obvious that this Diplegic person is of moderate involvement since almost all of the indexes are contained in the moderate pathology area. The increased variability in the Trasnverse plane Pelvis motion can be noticed as well as the increased asymmetry in the Transverse plane Hip motion.
