Age

18 Years to 40 Years

Inclusion criteria

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.

Exclusion criteria

Exclusion criteria: Lower limb injuries during the last 3 months, due to which physical activity was not possible for more than one day, surgery on the affected lower extremity in the last 12 months, surgery on the affected ankle, neurological or peripheral vascular disease, medication with influence On the balance, therapeutic treatment on the lower limb and back (eg physiotherapy or osteopathy) during the duration of the study, acute infections, fever.

Design outcomes

Primary

Measure	Time frame
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

Measure	Time frame
Evaluation of the 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. 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. 3. Reliability measurement of time-to-stabilization.	—
