In February 2009 a team led by Dr Thomas Bochdanksy, head of the department of Physical Medicine and Rehabilitation at the regional hospital in Feldkirch, Austria, studied the effect of the kyBounder on 31 test subjects, compared with a conventional therapy mat.
He tested the instability caused by the mats based on the distance from subjects’ center of balance. The results showed that exercise on the kyBounder stimulates postural stability far more than on a conventional therapy mat. Dr Bochdansky believes that this intensive way of improving your balance boosts the functions of the deep muscles and, among other things, helps reduce pain, especially in the lumbar vertebrae.
How the kyBounder compares: huge demands placed on your balance system
The data show that greater control is needed to stand still on the kyBounder (= harder work). This is due to the high degree of instability which characterizes the kyBounder, and can be seen on all frequency levels (see graph). According to Bochdansky this result indicates that exercising on the kyBounder makes demands on all the main control systems (visual, vestibular and somatosensory).The expert’s positive interpretation of the study results is that as the kyBounder allows the exercise intensity to be increased, this also improves its effect.
What does instability mean for your body?
Your body reacts very sensitively to instability, as in everyday life it indicates a high risk of a fall. Confronted with an unstable surface, your body thus automatically tries to regain stability. In therapy, instability can be used in a highly targeted manner as a stimulus to exercise the body’s natural stabilization mechanisms. This improves your dynamic spine stabilization (= postural stability, core stability), which is a key factor in the occurrence of backache over long distances.
What benefit does instability have during sports or in therapy and rehabilitation?
The trunk is the basis for any movement in your extremities. Generally, it can be said that the stronger that basis is, the better (more precise, targeted, extreme) the movement is. Exercising on a kyBounder leads to a general improvement in your balance and can thus help reduce your risk of a fall. The kyBounder can play a valuable part in every field of preventive work (primary, secondary and tertiary prevention). Moreover, instability can also play a major role in improving your dynamic control of your joints, leading in the case of degenerative illnesses to better kinematics and kinetics and thus ideally distributing the load on your joints.
“When measuring balance we found that the kyBounder provided the most instability compared with other exercise mats. From this we can conclude that balance training on the kyBounder can have a greater effect on dynamically stabilizing the spine, and should thus have a high primary and secondary effect in preventing backache.” Dr. Thomas Bochdanksy, head of the department of Physical Medicine and Rehabilitation at the regional hospital in Feldkirch, Austria.
This instability is also provided by the kyBoot, meaning that the kyBoot should also provide effective exercise with its special walk-on-air sole.
