Twenty-four healthy young men were fitted with telemetrized electrogoniometer to measure hip, knee, ankle joint excursions in sagittal plane, also fitted with foot switches to measure heel and toe contact time. All of the acquired data were sampled by and stored in a computer system and determination of the mean values and dispersions were made. Major attention was focused on the area of angle-angle diagram loops to discuss the parameters which would be useful to evaluate the neuromuscular coordination and control and be of value in interpreting and assessing the diagram. Here we introduced some parameters and its normal value.

In order to establish the reliability of method, comparison of the result of the test and retest were performed.

The conclusions were as following

1) The test were reliable except some of foot switch information due to its easy malfunctioning.

2) The parameters introduced such as perimeter, area, PA value, α angle, β angle, two diameters of diagram, may be useful to evaluate neuromuscular coordination and control and to classify the type of angle-angle diagram.

Key Words: Electrogoniometer, Angle-angle diagram, Coordination
