Group 1: This cross-over RCT involves two periods. Period 1 with intervention and period 2 without intervention. During the period 1 with intervention, a total of six individual intervention sessions

Eligibility

Sex/Gender

All

Age

18 Years to 40 Years

Inclusion criteria

Inclusion criteria: Participants with chronic ankle instability, all together one trauma > 1 year, Identification of functional instability (IdFAI) = 11 points, Query 5 and 6 IdFAI: should be answered with „never“.

Exclusion criteria

Exclusion criteria: lower body injury< 3 months, due to which physical activity was not possible for more than 1 day, surgery on the affected lower extremity < 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
Muscle activation of the peroneus longus during landing after one-leg-drop-jump before and after multiple mobilizations (six intervention units) of the foot. 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 during landing after one-leg-drop-jump as a parameter for the postural control before phase 1 and after phase 1 as well as before phase 2 and after phase 2. The TTS values are recorded by means of a force measuring plate (Kistler Quattro Jump, Sindelfingen, Germany), the medial / lateral and the vertical ground reaction force are recorded with a sampling frequency of 1000 Hz, which is used to calculate the TTS. 2. Muscle activation of the Tibialis anterior, soleus, gastrognemius, quadriceps femoris, and biceps femoris during landing after one-leg-drop-jump before phase 1 and after Phase 1 and before phase 2 and after phase 2. 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 in period 1 and period 2.	—
