Treating Sports Injuries
- An acute twisting or overextension of a joint can lead to tears of muscles and tendons, called "strains," and tears of ligaments result in "sprains."
- In mild injuries, just a few fibers are torn or stretched. Severe injuries, where there is a tear through the full thickness of the structure, frequently require surgical intervention.
- The intervertebral disc, a ligament between the vertebrae of the spine that works as a shock absorber, can also be torn, resulting in a disc bulge and/or herniation.
- In those who are training too much, overuse of a particular joint or joints in the body can result in pain and dysfunction. There injuries are called "overuse syndromes."
- A common overuse injury is tendinosis, a condition in which the tendon becomes inflamed from repetitive use.
- Some athletes may experience a stress fracture, which occurs when an abnormal amount of stress is placed on a normal bone, such as in a runner who rapidly increases the amount of mileage, rather than gradually progressing to longer distances.
- Shin splints are caused by microfractures on the front surface of the tibia (shin bone). This is most often seen in runners, although other athletes can be affected.
Sports injuries are most often diagnosed from the history of the activity which brought on the pain, along with a physical examination. In some cases, X-rays are necessary to rule out a fracture. Fractures require the application of some stabilizing device, such as a cast, after the bone is put back into position. Rarely, surgical intervention is required. Magnetic resonance imaging (MRI) and ultrasound may also be used.
There is a relatively standard treatment protocol for most types of sports injuries, which involves:
- Rest. Generally no more than 48 hours of rest and/or immobilization is needed, depending on the severity of the injury.
- Ice or heat can help with pain reduction and tissue healing.
- Compression of the area may reduce the amount of swelling from the injury.
- Elevation of the injured arm or leg above the level of the heart is thought to be helpful in reducing swelling.
- Joint manipulation. Recent research has shown that, in some cases, joint manipulation can help with pain reduction and more rapid recovery.

Bike Fit Basics
1. 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 an inch or two of clearance for a road of hybrid bike and about four inches of clearance for a mountain bike.
Always Wear a Helmet!
•The helmet should be level on the head, and it must cover the forehead.
•The Y of the 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.

Forward Head Posture
In the poster on the left, the first sketch (top-left) represents “perfect” head posture. A line dropped from the center of the external auditory meatus (EAM) would land directly in the center of the shoulder (the tip of the acromion process). The graphic on the right demonstrates the progression of forward head posture (occasionally referred to as “anterior head translation”).
According to Kapandji (Physiology of the Joints, Volume III), for every inch your head moves forwards, it gains 10 pounds in weight, as far as the muscles in your upper back and neck are concerned, because they have to work that much harder to keep the head (chin) from dropping onto your chest. This also forces the suboccipital muscles (they raise the chin) to remain in constant contraction, putting pressure on the 3 Suboccipital nerves. This nerve compression may cause headaches at the base of the skull. Pressure on the suboccipital nerves can also mimic sinus (frontal) headaches.
Rene Cailliet M.D., famous medical author and former director of the department of physical medicine and rehabilitation at the University of Southern California states:
“Head in forward posture can add up to thirty pounds of abnormal leverage on the cervical spine. This can pull the entire spine out of alignment. Forward head posture (FHP) may result in the loss of 30% of vital lung capacity. These breath-related effects are primarily due to the loss of the cervical lordosis, which blocks the action of the hyoid muscles, especially the inferior hyoid responsible for helping lift the first rib during inhalation.”
Persistent forward head posture (a.k.a “hyperkyphotic posture”) puts compressive loads upon the upper thoracic vertebra, and is also associated with the development of Upper Thoracic Hump, which can devolve into Dowager Hump when the vertebra develop compression fractures (anterior wedging). A recent study found this hyperkyphotic posture was associated with a 1.44 greater rate of mortality.
It's not uncommon to observe 2" of anterior head placement in new patients. Would you be surprised that your neck and shoulders hurt if you had a 20-pound watermelon hanging around your neck? That's what forward head posture can do to you. Left uncorrected, FHP will continue to decline. Chiropractic can be very corrective, especially in the hands of a chiropractic rehabilitationist. Our specialty is in reversing the joint fixations (what we refer to as “subluxations”) and in re-invigorating the muscles that normally retract the head.
