Brief summary in scientific language
The capsule and the ligaments contain mechanoreceptors (Golgi tendon organs, Ruffini and Vater-Pacini bodies) and free nerve endings. These have different somatosensory tasks in the area of afferent information transfer of the joint position to the central-nervous-system (CNS). If they are impaired in their function by an injury, for example in the case of a ankle joint distortion, it can be assumed that the control loop between afferent and efference no longer functions correctly. This may lead to altered proprioception and postural control (Hertel, 2002; Hubbard & Hertel, 2006; McCriskin et al., 2015). Hopkins (2009) postulated that patients with CAI show a longer latency of the peroneus longus muscle during walking and altered activation patterns in a jump. In addition, deficits in sensorimotor and postural control are described in patients with CAI (Munn et al., 2010; Steib & Pfeifer, 2015). Passive ankle mobilization and ankle manipulation improves the range of motion of the ankle joint (Loudon, Reiman, & Sylvain, 2014; Marron-Gomez, Rodriguez-Fernandez, & Martin-Urrialde, 2015). It can also be assumed that mobilization affects the mechanoreceptors of the capsule (Baeske, 2016). It can be assumed that the mechanoreceptors in the capsule are affected by passive joint mobilization, resulting in improved information transfer, which can improve muscle activation and postural control. This effect would also be desirable in patients with a CAI. Based from that described above, this study examine short-term effects after an unique manual ankle mobilization on muscle activation of the leg muscles and the postural control in patients with CAI.

- S93 - Dislocation, sprain and strain of joints and ligaments at ankle and foot level

Interventions, Observational Groups
- Arm 1:
- The participants will get an intervention (mobilization): The mobilization thrust direction is from anterior to posterior in a final degree of dorsiflexion of the talocruralis joint. Mobilization: during 5 x 1 minute, each with an ease-off of 10 seconds in between. In a Grade III mobilization to Maitland, a passive movement is performed, which has a large amplitude and enters the resistance. It is measured before and after the intervention.
- Arm 2:
- The participants sit on a chair for 10 minutes. Before and after the rest a measurement will be performed.
Endpoints
- Primary outcome:
- 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:
- 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.
