This study has recruited 50 Participants

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.

Effectivity of Slackline-Training in Physiotherapy

Official Title

Effectivity of Slackline-Training in Physiotherapy - a Randomised Controlled Study

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.

Treatments and/or Procedures

Wobbling board

Wobbling Board CE: certificated by european law for medical devices (EG Richtlinie 93/42/EWG)

Post training

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. control

beginners have to train 9 times ~15minutes within y few weeks.

Fix visual anchor

Professionals have to gaze at a fixed visual anchor during the slacklining.

Pre training

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

Moving visual anchor

Professionals have to gaze at a moving visual anchor during the slacklining.

Slackline

Slackbase PRO CE: certificated by european law for medical devices (EG Richtlinie 93/42/EWG)

Outcome Measures

Outcome measures are the tests that investigators perform to prove whether or not a treatment being tested in a clinical trial is having any effect.

Primary

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: a. slackline compared to wobble board PROFESIONALS: slackline compared to wobble board 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

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

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

average of 6 weeks

Other

Y-balance-performance: measured in cm

average of 6 weeks

Other

MFT challenge disc: measured in a score

single investigation for arms: BEGINNERS: a. slackline training vs. standing-on-1-leg training vs. control a. pre-training compared to post-training, expected training period average of 6 weeks, totally 9 trainings of 15 minutes each -------------------------------------- MFT Scale (Multi Functional Training) Scale Construct The diagnostics and scoring on the Challenge Disc is based on experience with other similar test equipment. Espacially the widely used Biodex Stability System. Total Score Total score is composed of the anterior-posterior and lateral-medial movement on the board. Scale Range Score 1-5 (1= good; 5=bad) Subscales unknown

average of 6 weeks
