Does Your Bike “Fit” You?

Bike Fit Basics

Whether you ride on-road or off, pedal casually or competitively, it’s important to pay close attention to how your bicycle fits your body. A properly fitted bike will allow you to ride comfortably and safely, avoid injury, and produce more power, so you go faster with the same or less effort.

In general, when fitting a bicycle, there are five basic components to consider:
1. Frame size
2. Saddle (seat) height
3. Saddle position
4. Saddle tilt
5. Handlebar position
Frame Size
Frame size is perhaps the most important of all measurements because once you purchase the bike, there are very few—if any—minor adjustments that can affect the overall frame. Frame size is not necessarily dependent on your height; rather, it is more a matter of leg length. Simply, the frame should be easily straddled with both feet flat on the ground, and with perhaps an inch or two of clearance.

• For a road or hybrid bike, you should have an inch or two of clearance between your crotch and the top tube.
• For a mountain bike, clearance should be about four inches—especially if you plan to ride in rugged terrain where an unplanned dismount is likely.

Saddle Height
A saddle (seat) set too high or too low can cause pain and lead to injuries of the back and knees, and it will also affect the efficiency of each pedal stroke. As a starting point, set the saddle height so that your knee is slightly bent when the pedal is at its lowest position and the ball of your foot is on the pedal. It is recommended to make adjustments in very small increments and, if applicable, to wear your cycling shoes during the adjustment process.
Saddle Position
To check the saddle position, sit on your bicycle—using a friend or a stationary object to keep yourself balanced— and rotate your pedals until they are horizontal (at the 3 o’clock and 9 o’clock positions). If your saddle is positioned properly, your forward knee should be directly over the respective pedal axle (with the ball of your foot on the pedal). For precise measurement, use a plumb-bob to help you visualize the alignment. If adjustments are needed, loosen the seat post and slide the saddle forward or backward, keeping the seat level.
Saddle Tilt and Design
Generally speaking, your saddle should be level. Check this adjustment by using a carpenter’s level balanced on the saddle while the bike is on level ground. If your saddle tips too much in either direction, pressure will be placed on your arms, shoulders, and lower back.
Handlebar Position and Distance
Handlebar setup is a matter of personal preference because it will affect shoulder, neck, and back comfort. Generally, handlebars are positioned higher for comfort (a more upright riding position) and lower for improved aerodynamics.
Always Wear a Helmet!
A bicycle crash can happen at any time; however, according to the National Highway Safety Traffic Administration, a properly fitted bicycle helmet reduces the risk of head injury by as much as 85 percent and the risk of brain injury by as much as 88 percent. The following are tips to help ensure the correct helmet fit:
• The helmet should be level on the head, and it must cover the forehead.
• The Y of the side straps should meet just below the ear.
• The chin strap should be snug against the chin so that when you open the mouth very wide, the helmet pulls down a little.
• Put your palm on the front of the helmet, and push up and back. If it moves more than an inch, more fitting is required.
• Shake your head around. If the helmet dislodges, work on the strap adjustments.
• Do not wear a hat under the helmet.
• All helmets sold in bike shops must be approved by the U.S. Consumer Product Safety Commission (CPSC) and should carry a CPSC sticker.

Enjoying the Outdoors with Baby!

From biking and hiking to walking and jogging, today's parents are keeping fit and bonding with their babies in the process. With an array of products unheard of a generation ago - like baby carriers, joggers and trailers - even the tiniest among us are enjoying the great outdoors. But while these items can make life easier and more enjoyable for both parent and child, they can be the cause of pain and injury if not used properly. The American Chiropractic Association (ACA) urges you to exercise caution and good judgment while exercising with your baby.

Biking
When biking with a child on board, use a trailer, a rolling ride-along that hitches to the back end of a bike. It is a much safer option than a carrier, a "passenger" seat that sits directly on the bike, according to Dr. Scott Bautch, a member of ACA's Council on Occupational Health. Dr. Bautch prefers trailers because of their added stability. He cautions that carriers can decrease a bike's stability, possibly causing it to topple and injure both the parent and child.

To further ensure the child's safety while biking, keep the following tips in mind:
• The trailer must be equipped with a harness that can be placed over the child's body. The harness should be complicated enough that the child cannot unhook it or wiggle out of it.
• A screen that covers the front of the trailer will add an extra line of protection against stray pebbles and other flying objects.
• Be sure to select a trailer that has large, bicycle-style tires, which will add stability and ease to your ride.
• Protect your child's head with a sturdy, adjustable helmet that can be sized to fit properly. If the helmet rests too high, it will expose part of the child's head, leaving it susceptible to injury.
• Bike only on smooth surfaces for optimal control.
• Only an experienced rider should attempt to bike with a child on board at all. And even then, the rider should practice with a ride-along trailer for two weeks before riding with a real child - in an effort to get a feel for the strength and coordination necessary to maneuver the bike.
Jogging
If you wish to go for a jog and bring your child along for the ride, the baby jogger is your best option. A baby jogger is a rolling pushcart that a parent can jog behind, using handlebars to maneuver. Here are some rules of thumb to consider:
• Make sure the handlebars of the jogger are both large and adjustable, so that they fit comfortably into your hands for complete control. The handlebars should be kept as upright as possible.
• Handbrakes and a locking mechanism are a necessity.
• Look for a jogger with a good shoulder harness to keep the child secure.
• Large, bicycle-style tires offer more control and stability.
• A screen over the front of the jogger adds to its safety by deflecting stray flying objects.
• Jog only on smooth surfaces.
Backpack-Style and Front-Side Baby Carriers
For parents who prefer walking or hiking with their little ones, a backpack-style or front-side baby carrier could be for you. Dr. Bautch cautions, however, that there are risks involved with carrying an infant on your back in a backpack-style carrier. "The cervical spine of a child less than one year old is not fully developed. It is important at that age that the head does not bob around. The backpack-type carrier is not ideal because the parent cannot watch to make sure the child's head is stable. A front-side carrier is better for a very young child," explains Dr. Bautch.

Dr. Bautch also urges you to think about the following:
• A backpack-style or front-side carrier decreases a parent's stability when walking or hiking. It is critical that a parent gets into shape before attempting to use one of these products.
• Since these carriers will change the feel of walking or hiking quite a bit, they should not be used by beginning walkers or hikers.
• If using a backpack-style or front-side baby carrier, make sure to select one with wide straps for your shoulders and waist. This will help distribute the carrier's weight evenly. The shoulder straps should fit comfortably over the center of your collarbone.
• The carrier should include a harness to keep the child stable.
• Once you place the child in the carrier, check to make sure there is no bunching of material against the child's body, particularly on the back, buttocks and spine. Isolated, uneven pressure like this can produce pain.
Baby Slings
The "baby sling" is becoming more and more popular for its versatility of positions and comfort. But if you wish to use a baby sling, keep in mind that it is intended only for very young infants and follows these tips:
• A baby can become very hot inside the sling, so be mindful of the temperature around you. Also, make certain the baby's breathing is clear and unobstructed by the sling's material.
• Never run or jog while carrying a baby in any backpack-style carrier, front-side carrier or baby sling. A baby's body is not adjusted to the cyclic pattern that is a part of running and jogging. This motion can do damage to the baby's neck, spine and/or brain.
Take Care of Yourself
Finally, don't forget about your own health and comfort. When lifting a child to place him or her into a trailer or jogger, exercise caution. Don't bend from the waist, but begin in a 3-point squat and implement a two-stage lift that consists of a) pulling the child up to your chest and then b) lifting straight up with your leg muscles. Stay as close to the car seat or trailer as possible and place the child into it without reaching, stretching or twisting. The further the child is from your body, the more strain you will place on your spine and musculoskeletal system.

Chiropractic Care Can Help
If you or your child experiences any pain or discomfort resulting from these or other outdoor activities, call your doctor of chiropractic. Doctors of chiropractic are licensed and trained to diagnose and treat patients of all ages, and can provide health tips for you and your children that will make enjoying outdoor activities safer and more enjoyable.

Osteoporosis: Not Just An Elderly Disease

It used to be that osteoporosis was considered a disease that affected only the elderly. We particularly associated osteoporosis with older women whose backs were slightly hunched over or those who could no longer stand up straight. Today, the truth is that an estimated 20 million American women suffer from osteoporosis, and 80 percent of them don't even know it.

Osteoporosis is a chronic, progressive condition that steals bone from the body, leading to fractures of the hip, spine and wrist. Older people can suffer disability and even death from osteoporosis-related fractures. Alarmingly, one in two women and one in eight men will suffer from an osteoporosis-related fracture in his or her lifetime.

Many people confuse osteoporosis with arthritis, and wait for swollen joints and discomfort before being tested. Even though osteoporosis is painless until a bone fracture occurs, it is important to find out how healthy your bones are now and if need be, adjust your lifestyle to avoid this brittle bone disease. The American Chiropractic Association recommends the following tips to maintain healthy bones:

• Start a regular exercise program. Walking, skipping rope, jogging, playing racquet sports, swimming and aerobics are all helpful in reducing the risk of osteoporosis. Exercising for 20 minutes, three times a week, is helpful.
• Although weight lifting exercises are generally recommended, the National Osteoporosis Foundation says those suffering from osteoporosis should consult their health care practitioner before beginning a weight lifting program because excessive strain on the bones could result.
• Those with severe osteoporosis and who have suffered from fractures may find Tai Chi, a form of martial arts, to be a beneficial strength training exercise system.
• People suffering from osteoporosis should be careful when bending and lifting heavy objects, including grandchildren. Bend from the knees, not the waist, when lifting, and try to avoid hunching while sitting or standing.
• Be sure to include calcium in your daily diet. The National Institutes of Health's recommendations are 1,000 mg/day for post-menopausal women taking estrogen; 1,500 mg/day for postmenopausal women not taking estrogen, and 1,500 mg/day for men and women over 65 years of age.
• If you are looking for a calcium supplement, try one that's highly absorbable, such as microcrystalline hydroxyapatite concentrate (MCHC), or one of the malates, fumarates, succinates, glutarates, or citrates. But don't overdo it. Taking more than the recommended amount of calcium may cause kidney stones.
• Consider taking additional nutritional supplements, such as vitamin D, C, magnesium, zinc and silica after consulting with your doctor of chiropractic.
• Eat a healthy, balanced diet, including fresh vegetables, fruit, nuts and seeds. Try broccoli, kale, collard greens, cabbage and turnip greens. Experiment with tofu, salmon, sardines and grains. Low-fat milk and/or yogurt are good sources of calcium. (A glass of low-fat milk and a cup of yogurt add 600 mg of calcium to your daily diet.)
• Drink 8 eight-ounce glasses of water a day (herb teas, juices and coffee are not a substitute for water.) Avoid caffeine, carbonated sodas, alcohol, baked goods and junk food.
• Watch your animal protein intake.

Chiropractic Care Can Help...
Talk to your doctor of chiropractic about ways to improve the health of your bones. Doctors of chiropractic are licensed and trained to treat patients of all ages and can help people suffering from osteoporosis lead healthier lives.

Scoliosis

Scoliosis affects 5 to 7 million people in the United States. More than a half million visits are made to doctors’ offices each year for evaluation and treatment of scoliosis. Although scoliosis can begin at any age, it most often develops in adolescents between the ages of 10 and 15. Girls are more commonly affected than boys. Because scoliosis can be inherited, children whose parents or siblings are affected by it should definitely be evaluated by a trained professional.

What is scoliosis?

Because we walk on 2 feet, the human nervous system constantly works through reflexes and postural control to keep our spine in a straight line from side to side. Occasionally, a lateral (sideways) curvature develops. If the curvature is larger than 10 degrees, it is called scoliosis. Curves less than 10 degrees are often just postural changes. Scoliosis can also be accompanied by lordosis (abnormal curvature toward the front) or kyphosis (abnormal curvature toward the back). In most cases, the vertebrae are also rotated.

In more than 80% of cases, the cause of scoliotic curvatures is unknown; we call this condition idiopathic scoliosis. In other cases, trauma, neurological disease, tumors, and the like are responsible. Functional scoliosis is often caused by some postural problem, muscle spasm, or leg-length inequality, which can often be addressed. Structural scoliosis does not reduce with postural maneuvers. Either type can be idiopathic or have an underlying cause.

What are the symptoms of scoliosis?

Scoliosis can significantly affect the quality of life by limiting activity, causing pain, reducing lung function, or affecting heart function. Diminished self-esteem and other psychological problems are also seen. Because scoliosis occurs most commonly during adolescence, teens with extreme spinal deviations from the norm are often teased by their peers.

Fortunately, 4 out of 5 people with scoliosis have curves of less than 20 degrees, which are usually not detectable to the untrained eye. These small curves are typically no cause for great concern, provided there are no signs of further progression. In growing children and adolescents, however, mild curvatures can worsen quite rapidly—by 10 degrees or more—in a few months. Therefore, frequent checkups are often necessary for this age group.

How is scoliosis evaluated?

Evaluation begins with a thorough history and physical examination, including postural analysis. If a scoliotic curvature is discovered, a more in-depth evaluation is needed. This might include a search for birth defects, trauma, and other factors that can cause structural curves.

Patients with substantial spinal curvatures very often require an x-ray evaluation of the spine. The procedure helps determine the location and magnitude of the scoliosis, along with an underlying cause not evident on physical examination, other associated curvatures, and the health of other organ systems that might be affected by the scoliosis. In addition, x-rays of the wrist are often performed. These films help determine the skeletal age of the person, to see if it matches an accepted standard, which helps the doctor determine the likelihood of progression. Depending on the scoliosis severity, x-rays may need to be repeated as often as every 3 to 4 months to as little as once every few years.

Other tests, including evaluation by a Scoliometer™, might also be ordered by the doctor. This device measures the size, by angle, of the rib hump associated with the scoliosis. It is non-invasive, painless, and requires no special procedures. A Scoliometer™ is best used as a guide concerning progression in a person with a known scoliosis—not as a screening device.

Is scoliosis always progressive?

Generally, it is not. In fact, the vast majority of scolioses remains mild, is not progressive, and requires little treatment, if any.

In one group of patients, however, scoliosis is often more progressive. This group is made up of young girls who have scolioses of 25 degrees or larger, but who have not yet had their first menstrual period. Girls generally grow quite quickly during the 12 months before their first period and if they have scolioses, the curvatures tend to progress rapidly. In girls who have already had their first periods, the rate of growth is slower, so their curves tend to progress more slowly.

What is the treatment for scoliosis?

There are generally three treatment options for scoliosis—careful observation, bracing, and surgery. Careful observation is the most common “treatment,” as most mild scolioses do not progress and cause few, if any, physical problems. Bracing is generally reserved for children who have not reached skeletal maturity (the time when the skeleton stops growing), and who have curves between 25 and 45 degrees. Surgery is generally used in the few cases where the curves are greater than 45 degrees and progressive, and/or when the scoliosis may affect the function of the heart, lungs, or other vital organs.

Spinal manipulation, therapeutic exercise, and electrical muscle stimulation have also been advocated in the treatment of scoliosis. None of these therapies alone has been shown to consistently reduce scoliosis or to make the curvatures worse. For patients with back pain along with the scoliosis, manipulation and exercise may be of help.

Most people with scoliosis lead normal, happy, and productive lives. Physical activity including exercise is generally well-tolerated and should be encouraged in most cases
