Brief Summary
The investigators want to investigate the reliability (variability) of a new device, that should be able to measure lower leg compartment pressure non-invasively. Therefore the tool is used under different circumstances. The introduced differences in circumstances are:
- Measurements at several time points
- Measurements using different anatomical landmarks
- Measurements by different researchers
- Measurements in rest and after exercise This study's results are important to create a reliable measurement tools for patients with lower leg symptoms. In this way the diagnosis can be improved and as well the treatments given to the patients. It is expected that the variability of the device will be low compared to current techniques.

Outcome Measures
Primary Outcomes (1)
Inter-class correlation
The primary endpoint of inter-observer variability will be the intraclass correlation coefficient (ICC) of agreement between three observers, four sites per subject, and four repetitions per measurement. The ICC will be assessed using a two-way random effects model. Both observers and subjects will be included as random effects. The first measurement for each location will be taken from every observer to calculate the ICC. Apart from that, the ICC will be measured using the average of the four repetitions of ratings, to estimate the effect on the ICC of repetitive measurements. "Good reliability" classification will be reached if the lower bound of the computed ICC confidence interval does not fall below 0.75.
1 session of approximately 90 minutes

Exercise effect on compressibility

Study Arms (1)
Healthy Volunteers
EXPERIMENTALHealthy subjects are not subjected to any type of treatment besides non-invasive lower leg muscle compressibility measurements in rest and after exercise. All 35 healthy subjects will undergo four times four measurements in rest (m. tibialis anterior of both legs, using two different internal landmarks). These four times four measurements in rest will each be done by three observers. To measure the effect of exercise, compressibility will be measured immediately, one minute, and five minutes after a standard treadmill exercise at just one leg. The treadmill exercise and the corresponding measurements will be performed twice to address for measurements of both legs.
Interventions
CPM#1 measurements: Step 1: Manual investigation to identify the compartment for compressibility measurements Step 2: Marking the location for compressibility measurements Step 3 - Examination with CPM#1 * Place the probe on the target area * Identify correct landmark * Compress the compartment * Increase steadily the pressure applied by the CP probe to 80 mmHg.
Exercise: Step 1: Participants will walk on a treadmill with standardized walking speed (5.0 km/hour) and slope (15%) for 5 minutes. Step 2: Immediate, one minute, and five minutes post-exercise CPM#1 measurements will be performed at one leg. Exercise and post-exercise CPM#1 measurements will be repeated for the other leg.
Questionnaires NIAPS questionnaire: Baseline NIAPS questionnaire with one additional question about leg dominance. Experience questionnaire: Scores 1-5, questioning the intensity, how painful, the nuisance, the duration of the study and the non-invasive pressure measurements.
