Effectivity of Slackline-Training in Physiotherapy
A study testing Slackline, Wobbling Board and Pre-training in people with Healthy Volunteers and Persons With no Known Significant Health Problems, run by THIM - die internationale Hochschule für Physiotherapie at 1 site in Switzerland.
Trial 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. Read more about this study

About this study
Official title: Effectivity of Slackline-Training in Physiotherapy - a Randomised Controlled Study
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.
Read the 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.

Pre-trainingDevice
First investigation of the beginners with less than 1 hour experience with slacklining.

Professionals have to gaze at a fixed visual anchor during the slacklining.
Moving visual anchorDevice
Professionals have to gaze at a moving visual anchor during the slacklining.
Post-trainingDevice
Second investigation of the beginners occurs after a training session of 9 times 30 minutes within a few weeks.
Slackline vs. standing-on-1-leg vs. controlDevice
beginners have to train 9 times ~15minutes within y few weeks.

| beginners | Experimental | balancing on the slackline / wobbling board 3 times by 30 seconds pre-training compared to post-training Receives: Device: Slackline; Device: Wobbling Board; Device: Pre-training; Device: Post-training; Device: Slackline vs. standing-on-1-leg vs. control |
What is being measured
The primary outcome is the main question the study is designed to answer.
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:
- BEGINNERS:
- slackline compared to wobble board
- PROFESIONALS:
- slackline compared to wobble board
- fix visual anchor compared to moving visual anchor double investigation: 1. BEGINNERS
- pre-training compared to post-training, expected training period average of 6 weeks, totally 9 trainings of 30 minutes each
Measured: 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]
