Why is it that most running injuries occur at the knee or in the lower leg? Is there some common factor that might be involved? The authors of this study set out to look for some answers to these questions. They didn't do a study themselves of runners. Instead they turned to the literature and did a search of all the published articles on running injuries. Research studies like this are possible now that everything is contained within an electronic database. Four of the most well-respected electronic databases (e.g., MEDLINE, EMBASE, PsychoInfo, CINAHL) were accessed for information on risk factors for overuse running injuries. By doing a search with words like running , injury , mechanics . and knee , they were able to find 283 articles on running injuries published between 1980 and 2008. They narrowed the search down by looking for running injuries in long-distance runners who ran at least 20 kilometers (12 miles) each week. The athletes were recreational or competitive runners (not elit...
I have migraines that cause my face to go numb, both my legs to go weak and get pins and needles and burning sensations. I can have altered sensation in both my feet and legs at the same time, this usually only lasts for short periods of time but happens on and off with twitching in the numb areas. Sometimes this can make it difficult to walk. I can also get a tingling tongue. I also sometimes get stabbing eye pain. I never feel sick or light sensitive but I have stabbing like pains in my head, like an electrical bolt. I have had repeat brain MRI on a T3 machine which have been normal. I never usually get severe headache just more weird sensations in my head.
Can migraine cause both legs to go numb at the same time? Or both arms at the same time? I was told migraine is only one sided? I have had spinal MRI and this is normal too.
Thank you for any info. Cheers, Eleanor.
Although the headache and many of the other sy...
A basic idea in science says that for every action there's an equal and opposite reaction. If someone gets pushed, the usual reaction is to shove back. The same thing happens when we walk. The foot and the ground each exert a certain amount of force on each other. What if someone has hip pain from arthritis? The natural response is to change how fast and how hard the foot hits the ground. However, the force of the ground meeting the foot doesn't change. Where does the rest of that energy go? Interesting question! When it is necessary to change the way we walk, the body compensates by moving differently. The force goes to a different section of the body. Suddenly, the foot isn't striking the ground on the painful side of the body as hard as it is on the other. The force or action is shifted away from the hip to the pelvis and the knee. How do scientists know that? Advances in camera technology have made it possible to study how people walk. Specialized cameras can capture movement during...
