Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Muscle activity using surface electromyography device. 1. measuring amplitude of muscle activation in mV (millivolt) 2. measuring frequency pattern of muscle activation to distinguish /detect activation of slow and fast muscle fibers

    single investigation for arms: 1. BEGINNERS: a. slackline compared to wobble board 2. PROFESIONALS: 1. slackline compared to wobble board 2. fix visual anchor compared to moving visual anchor double investigation: 1. BEGINNERS a. pre-training compared to post-training, expected training period average of 6 weeks, totally 9 trainings of 30 minutes each

    average of 6 weeks

Secondary Outcomes (1)

  • Whole body kinematics (composite outcome measure): a. calculating joint angles [deg & deg/s] b. calculating absolute and relative body part movements (such as trunk, pelvis, head): tilts & translations [mm, mm/s]

    average of 6 weeks

Other Outcomes (3)

  • measuring the duration of a trial (if less than 30 sec): measured in sec

    average of 6 weeks

  • Y-balance-performance: measured in cm

    average of 6 weeks

  • MFT challenge disc: measured in a score

    average of 6 weeks
