Effectivity of Slackline-Training in Physiotherapy
Condition: Healthy Volunteers; Persons With no Known Significant Health Problems
Study type: Interventional

Summary: 
      Slacklines have been established in the last few years as a training equipment in sports such
      as climbing, skiing and others to increase postural control. Furthermore, slacklines are used
      in physiotherapy in terms of stabilizing training such as wobbling boards.

      However, if slackline training is effective in rehabilitation has not been investigated yet.
      Therefore, to goal of this study will be to investigate the effectivity of slackline training
      in physiotherapy compared to a wobbling board with a single tilting axis.

      Outcomes will be electromyographic-data and the kinetics of the whole body.
    

Detailed description: 
      Comparing beginners pre-training (less than 1 hour of slackline training) to post-training (9
      times 30 minutes of individual, controlled training) to investigate the effects of balance
      training on a slackline.

      Comparing beginners (less than 1 hour of slackline training) to professionals (more than 100
      hours of slackline training) to investigate differences in balance strategies.

      Comparing professionals during slacklining under two different conditions of their visual
      anchor: fix vs. moving. This to investigate the role of the visual system during balance
      reactions.

      Comparing slackline training versus a demanding training standing-on-1-leg. We do compare
      Y-balance-performance, performance on the MFT challenge disc, each compared with
      simultanousely recording body Sway (lower trunk) with SwayStar.

      Muscle activity will be investigated by absolute amplitude (mV) and frequency to get an idea
      of which muscle fibers are acting during the task and how the activation pattern may change
      through motor learning.

      Body kinematics should show movement strategies especially differences in roll and pitch
      control of the body.
