There’s often a lot of fuss made about biomechanics and injury prevention and how they relate to one another. In the clinic this tends to appear in the misconception that the better my running technique is, or other appropriate activity, the less likely I am to get injured. Yet whilst this is true to some extent there’s less of a direct relationship than you might think between biomechanics and injury. If we are looking at how likely we are to get injured how well the movement is performed is less important than how much load is placed on the tissues involved when performing it. So how much you do has a much bigger impact on whether an injury might occur or not rather than the actual way you’re doing it. Continue reading “How do biomechanics relate to injury?”
I often find when clients develop nonspecific aches and pains they start, almost randomly, introducing low load rehab work into their program in an attempt to solve the problem. This is usually done after a quick google search which makes various reasonable suggestions as to what might be wrong and the exercises to do to help the problem. This though really doesn’t tackle the problem well, if at all, given it misses out looking at why the aches and pains developed to begin with.
When the sciatic nerve becomes irritated it can create pain, pins and needles or numbness down the back of the leg.
Nerves can be compressed, trapped or irritated in a number of ways at the point where it leaves the spine but there is quite a bit of space around the nerve at this point so the chances of it getting pinched here are low. If it does happen the most common of way is where a disc herniates and pushes against the nerve. Whilst this is the most common way for the nerve to become “trapped” it is still only likely to affect 1 in 10 of those suffering from back pain. Continue reading “What can you do about sciatica?”
Last weekend I had the pleasure, again, of doing a workshop at Crossfit BG with Bob Clark and the crew. I had done a couple last year and they had been a lot of fun and this one was no exception. The workshop covered all things deadlifting and we looked at warm up ideas, breathing, deadlift technique and why we want to maintain a neutral or fixed spinal position.
This is great piece by Gregory Lehman and though a long one well worth reading it all. He looks at the pros and cons of maintaining a neutral spine and allowing spinal flexion to occur. Needless to say the case isn’t clear cut and it depends on your goals, tasks you require to do amongst other factors.
Correctly setting and bracing the abdominals during a barbell squat can make a significant difference to the feel of the movement though increasing torso stability. Properly engaging the abdominals will also improve hip range of movement which will make the bottom position feel easier to move into whilst maintaining an upright torso and aid in the reduction of unwanted spinal movement.
We should all be able to separate to a reasonable degree the movement of most joints of the body that is the movement of the wrist and elbow, the neck should be separate from shoulder girdle, lumbar spine from hip etc. Often annoying aches and pains and general poor movement can come from an inability to do this. Not always but often enough to warrant checking things out as over time it begins to limit our movement options.
Patellofemoral pain can be thought of where pain is present in and surrounding the tissues between the patella and the femur. The cause of the pain can be something of a mystery as it rarely develops quickly and isn’t the result of a traumatic incident the way a ligament tear is. The symptoms are often made worse by, though not exclusively, activities like squatting, lunging, kneeling, going down stairs or running downhill. In-other words relatively high load activities that put a lot of stress on or through the area. in addition to this sitting for long periods where the knee is flexed can also cause the symptoms to get worse.
