Abstract Introduction
To measure the elasticity of a compartment, the compression sonography is an appropriate non-invasive measure procedure. It’s a possible diagnostic tool for acute or chronic compartment syndrom. This method already has been used in earlier studies with human cadaver and animal models. So far there are no standard values for healthy subjects available. Goal of this study is to define the standard compartment elasticity in healthy subjects and to evaluate the reliability of the measurement method.

The study included 60 healthy subjects in whom the depth of the tibialis anterior compartment was measured while an external pressure of 10mmHg and 80mmHg was applied. A pressor manometer on top of the ultrasound probe was used to observe the external pressure. The ratio of the two values defined the elasticity. Two examiners each carried out two measurements on 10 subjects in order to asses the reliability of the measurements.

The mean elasticity of the tibialis anterior compartment was 15.9% (mean standard deviation: 3.7%; Range 5,0 – 22,2). There was no significant correlation of the circumferene of the lower leg, size, weight, sex, activity hours per week and type of activity (e.g. weightlifting / endurance sports). The intraobserver reliability showed an interclass-correlation (ICC) of 0,89 for the more experienced observer and 0,79 for the less experienced observer. The interobserver reliability shows an ICC of 0,78.

The mean elaysticity in the anterior tibialis compartment in healthy subjects was 15,9%. The elasticity didn’t show a dependence of the demographic parameter or the quantity and neither the typ of performed sport. The method of measurement showed a high reliability with a high intra- and interobserver correlation.
