What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| change of neuromuscular stiffness of the gastrocnemious muscles | biomechanical property of a muscle that characterizes the resistance to an external force that deforms its initial shape, using a Myoton. | 10 minutes before the intervention, and 1 minute after the intervention | 
| change of elasticity of the gastrocnemious muscles | Biomechanical property of a muscle that characterizes the ability to recover its initial shape after the removal of the external force that lead to its deformation, using a Myoton. | 10 minutes before the intervention, and 1 minute after the intervention | 
| change of relaxation of the gastrocnemious muscles | Time for a muscle to recover its shape from deformation after the removal of an external force, using a Myoton. | 10 minutes before the intervention, and 1 minute after the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| change of active dorsiflexion ROM | Active range of movement of the dorsiflexion of the ankle, using an inclinometer (degrees). | 4 minutes before the intervention, and 6 minute after the intervention | 
| change of pasive dorsiflexion ROM | Pasive range of movement of the dorsiflexion of the ankle, using an inclinometer (degrees). | 2 minutes before the intervention, and 8 minute after the intervention | 
| change of gastrocnemious strength | Isometric strength of the gastrocnemious muscles using a handheld dynamometer microFET 2 (newtons). | 5 minutes before the intervention, and 5 minute after the intervention | 
| change of pain intensity | How much pressure needs to be applied to cause pain | 8 minutes before the intervention, and 2 minute after the intervention | 
| change of pressure-pain threshold | How much pain the pacient reports while a pressure of 1kg/cm²/s is being applied over his gastrocnemious muscle | 7 minutes before the intervention, and 3 minute after the intervention |
