When considering a chronic injury it can be all too easy to focus on the specific site itself rather than the bigger picture or entire KiKinetic Chain (what’s happening further away and its subsequent affect)
Here’s a nice little research article that emphasises that principle. http://download.journals.elsevierhealth.com/pdfs/journals/1466-853X/PIIS1466853X12000089.pdf
The ability of your glute max (Gmax) to contract of course bears a direct relevance on chronic ankle instability and vice-versa (but you knew that of course!)
Perhaps some questions to ask of the participants with the ankle instability would have been:
- How was your initial rehabilitation prescribed?
- What protocol was followed?
- Was the emphasis on sagittal plane only and localised to the ankle/knee complex?
- Prior to injury had you only trained/loaded your Gmax in the sagittal plane predominately?
- What mobility had you previously through the foot/ankle/knee and hip complex?
All the above will relate to Gmax ‘s ability to load effectively in 3 dimensions.
Looking at the way our bones move, joints sense and our muscles react further up (in this case) the KiKinetic Chain will have a profound effect on our function!
Applying this Knowledge
- If you want to stimulate a high Gmax activation for function, consider a multiplane Hip/Knee/Ankle pattern (squat) (include transverse plane loading)
- Consider the Ki Kinetic Chain in relation to the objective movement Eg: If looking at the foot/ankle you need to consider what the Knee and Hip are also doing.
- Apply exercise/movement choices that take your clients through all 3 dimensions to prepare them appropriately for the demands their body will require.
In sports performance and everyday activity there will always be a degree of the unexpected or unknown range of movement that your clients will encounter, so prepare them in a progressive manner that not only replicates the movement but challenges them in the different planes – this will help stimulate the right proprioceptive feedback to enable their muscular system to deal with that range or motion safely!
