Effectivity of Slackline-Training in Physiotherapy

Not Applicable

Completed

• Conditions: Healthy Volunteers; Persons With no Known Significant Health Problems

• Registration Number: NCT02218086
• Lead Sponsor: THIM - die internationale Hochschule für Physiotherapie

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.

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.
