Inclusion Criteria

Participants with a chronically unstable ankle between 18 and 40 years of age, one injury (distorsion trauma) =1 year ago, Identification of functional instability (IdFAI) = 11 points, questions 5 and 6 of the IDFAI are not answered with never In the sense of the investigation.

Primary Outcome Measures

Name	Time	Method
M. peroneus longus activation during the landing from one-leg-drop-jump before and after a mobilization treatment of the ankle joint. The measurement will be carried out with the EMG device NORAXON TeleMyo 2400T G2 and one-way electrodes Ambu® Blue-Sensor.

Secondary Outcome Measures

Name	Time	Method
Evaluation of the<br>1. Time-to-stabilization in post-one-leg drop-jump assessment as a parameter for postural control. The anterior / posterior, the medial / lateral and the vertical ground reaction force with a sampling frequency of 1000 Hz are recorded as values using a force measuring plate (Kistler Quattro Jump, Sindelfingen, Germany), whereupon the TTS is calculated.<br>2. Muscle activation of the tibialis anterior, soleus, gastrognemius, quadriceps femoris, biceps femoris during landing after one-leg-drop-jump. The measurement will be carried out with the EMG device NORAXON TeleMyo 2400T G2 and one-way electrodes Ambu® Blue-Sensor.<br>3. Reliability measurement of time-to-stabilization.<br><br><br>
