Why Women Have More Foot, Knee, Hip, & Back Pain (and what you can do about it)
Posted Feb 21 2010 7:58am
Recently, EmpowHer invited me to write a column – here it is!
Pain and problems in the female foot are common—four times greater than for men. One study found that eighty-two percent of U.S. women report having foot pain, seventy-two percent have a foot deformity, and of all foot surgeries in the U.S., women undergo ninety percent of them.
Incredibly, it isn’t just the woman’s foot that leads in pain and problems. Females suffer with more ankle, leg, knee, hip, back, and neck problems. Clearly, when it comes to pain, this is one place women have too much equality!
Don’t despair! You can do simple things to prevent and alleviate pain now. Before I get to that, I want to explain why women are more prone than men to experience muscle-skeletal pain and ailments.
Feet are your foundation—whether you are man, woman or child. Strong, well-functioning feet and ankles are essential for support and balance. Working in unison with the body, your feet rapidly adapt to maintain balance over a variety of surface, whether you are running, walking, jogging, carrying a backpack, baby, purse, or all three, or even recovering from a sudden stumble. Feet do it all.
Having incredibly dynamic feet is great until something with them goes wrong. The smallest imbalance in your feet shows up as larger problems up above—in your knees, hips, back, and/or neck. Thus, a misaligned foot leads to a misaligned hip and/or back and/or neck.
Our body depends on agonist-antagonist muscles pulling against each other around our dozens of joints, and any joint imbalance will cause weakness of the muscles on one side of the joint and tension and strain of the muscles on the other side. The result is pain.
Further, these muscle-skeletal misalignments are more likely to occur due to the unique shape of the woman’s “normal” foot.
Compared with males, the female’s foot is generally shorter, narrower, and the length of instep is not as long. The average woman wears a size 8.5 (her foot is approximately twenty-four centimeters or 9.5 inches in length, about an inch shorter than the foot of the average male). The woman’s heel is narrower when compared to the ball of foot, which is wider and has a larger girth relative to the rest of the foot.
Overall, the woman’s foot is flatter than the male foot. This lower (or more pronated) foot is the root cause of the many of the body’s structural problems.
When feet flatten more than necessary (or over-pronate), the legs compensate by rotating excessively inward. This increased internal rotation creates abnormal stress on the knees causing them to become painful and deteriorate (osteoarthritis). With the knees now strained and out of alignment, a “ripple effect” can occur, causing imbalances, pain and arthritis in the hips, back and neck Since a woman’s foot is already on the flat-side, she is more predisposed to this painful cascade of events. (For those people whose feet are high arched (or supinated), a similar cascade of joint misalignment occurs leading to pain, imbalance and osteoarthritis.)
To make this chain-of-events even worse, a foot—male or female—that is on the flat side (excessively pronated) is more prone to become even weaker through a vicious downward foot-flattening cycle. Ultimately, this progressive flattening of the foot results in even more foot problems and more muscle-skeletal problems throughout the body.
To restore normal alignment to your body, you need to restore balance. The best way to do this is by strengthening agonist and antagonist muscles around your major joints with the goal of improving posture.
This sounds complicated, but there is a very simple way to start: walk barefoot. Shoes act as braces for your feet, altering the alignment of your body and negating the need for many muscles to work at all. Walking barefoot or in minimalist footwear (very flexible shoes such Terra Plana’s Vivo Barefoot), allows your body to “feel” the ground. Do as much walking barefoot as safely possible.
Barefoot activity allows your body’s muscles to develop and remarkably, an innate biofeedback system kicks in that tells your body how to make subtle, unconscious adjustments in the way you walk (your gait). To walk correctly takes a lot of work and study, and is beyond this article, but barefoot walking is a great way to start.
When you must wear shoes, less is more. As mentioned, wear minimalist shoes or very flexible, thin shoes that provide basic protection but still let your feet sense the ground beneath them.
Now, you can begin to understand the effect of foot misalignment and other joint imbalances on your body. The simplest way to start to strengthen your muscles and rebalance your body is through your feet, and how by losing your shoes, you will be on your way to losing the pain.
