Your head position and strain on your neck

For every inch your head is forward, your upper back and neck muscles have to hold an extra 10 lbs (~4.5 kg), as they have to work harder to keep the head (chin) from dropping to your chest. This also forces the sub-occipital muscles (they raise the chin) to remain in constant contraction, putting pressure on the three sub-occipital nerves. This nerve compression may cause headaches at the base of the skull or mimic sinus (frontal) headaches.
Kapandji, Physiology of the Joints, Volume III

We address this in two ways at Denver Chiropractic Center. We use chiropractic adjustments to realign the spine. We also use Active Release Techniques to release those tight sub-occipital muscles that can cause headaches, neck pain and fatigue.

Exercise: Watch Your Step!
When exercising, the force centered on your ankle can exceed up to seven times your body weight. 23,000 people sprain their ankle every day in the United States, resulting in 1.6 million doctor office visits annually. The direct and indirect costs (e.g., lost days from work) associated with treating ankle sprains exceed $1.1 billion annually. To make matters worse, these numbers do not take into account the long-term disability often associated with ankle sprains. Overweight athletes with a prior history of ankle sprain are 19 times more likely to suffer another ankle sprain.

Wellness/Prevention: Obesity Microbes?
New research suggests changing the mix of gut microbes can prevent obesity, but only if combined with a healthy diet. Eating a diet high in fruits and vegetables encourages leanness-related microbes to populate the gut leading to better weight control. However, a diet high in saturated fat and low in fruits and vegetables thwarts the invasion of microbes associated with leanness.

Chiropractic is an Effective Treatment For Sciatica Patients.

A year-long study compared chronic sciatica patients with symptomatic lumbar disk herniations who received either a microdiskectomy or 21 chiropractic visits. The researchers found that 60% of the patients who received chiropractic care benefited to the same degree as those who underwent surgery. The study’s authors recommend that patients with a symptomatic lumbar disk herniation try chiropractic first, before considering surgery.

Child with Headaches Responds to Chiropractic Adjustments.

This case study involved an eight-year-old boy with a complaint of daily headaches for three years. The child reported a significant decrease in headache frequency after one chiropractic treatment. The frequency of his headaches decreased to once per month after four adjustments. Since headaches are a common complaint in children, chiropractic treatment warrants further investigation.

Exercise Linked to Reduced Depression.

A recent review of 35 trials involving 1,356 individuals diagnosed with depression revealed that patients who engaged in exercise experienced a moderate decrease in depression symptoms. Researchers discovered that exercising proved as effective a treatment for depression as psychological therapy or taking antidepressants.

My oldest son Andrew and I ran the Hot Chocolate 5k on Sunday morning. This was his first race, and he went in hoping to be under 40 minutes. He did it in 33:33. Not bad for an year-old. I, of course, stayed with him. That was a great event for first-timers. I’d recommend it to anyone.

Mental Attitude: No Yelling.
Harsh verbal punishments, such as shouting, cursing, or using insults, are just as harmful to adolescents as physical discipline. Adolescents whose parents used harsh verbal punishment are more likely to suffer from depression and are more likely to engage in vandalism or aggressive behavior. Parental warmth, love, emotional support, and affection between parents and their kids is not enough to outweigh the negative effects of harsh verbal discipline.

Diet: Chew Your Food.
It is not a surprise that almonds are a great source of healthy fats and extra energy. However, the extent that almonds are chewed can make a difference in how much nutrition is absorbed by the body and how much is expelled. The more you chew, the more your body can use.

Exercise: Sudden Cardiac Death Risk reduced with Exercise.
Sudden cardiac death (SCD) accounts for 50% of all deaths from coronary heart disease, and is defined as death with cardiac origin within 24 hours after onset of symptoms. A 19-year study looked at the impact of high leisure-time physical activity (LTPA) combined with cardiorespiratory fitness (CRF) on the risk of SCD. The results showed that the risk of SDC was nearly double among men who are inactive (low CRF and low LTPA).

Chiropractic Manipulation and Childhood Ear Infections.

Forty six children with a diagnosis of otitis media who received chiropractic manipulation showed 93% improvement in all cases, 75% in 10 days or less, and 43% with only 1-2 treatments. Results indicate that limitation of medical intervention and the addition of chiropractic care may decrease the symptoms of ear infection in young children.

Money, ice baths and antibiotic resistance – This Week’s 1-Page Health News

Mental Attitude: With Age Comes Financial Wisdom.
In a study environment, older participants (ages 60-82) performed better than younger participants (ages 18-29) on finance-related topics where life experience and accumulated knowledge were favored. Such areas included temporal discounting, loss aversion, financial literacy, and debt literacy. The study authors believe that younger people would benefit from financial education earlier in life, before they begin making major financial decisions in adulthood.

Health Alert: Antibiotic Resistance Warning!
According to the Centers for Disease Control and Prevention (CDC), each year two million people contract either a bacterial or fungal infection that is resistant to at least one class of antibiotics. Antibiotic resistance has increased to the point where the CDC is calling for action to prevent the situation from progressing further. Their recommendations include preventing infections through more organized procedures in hospitals, better food handling, and the smarter use of antibiotics.

Diet: Passive Calorie Counting.
A new wearable computer called an eButton is able to autonomously view the food you are eating, identify it, and estimate the food’s nutritional content. Researchers believe passive devices such as the eButton could help people with conditions such as obesity, diabetes, and cardiovascular disease more accurately monitor their total caloric intake.

Exercise: No Ice Bath Please.
According to researchers, taking an ice bath after a workout does not effectively reduce soreness or strength loss and only mildly reduces inflammation. Lead researcher Dr. Naomi Crystal advises, “Use [ice baths] sparingly. Use them in tournament situations; use them with an athlete who has done something extraordinary. But for day-to-day athletes, I wouldn’t recommend them.”

A Treatment for Sciatica.

Research revealed 60% of patients with sciatica who failed medical management benefited from spinal manipulation. The authors concluded that patients with a symptomatic lumbar disc herniation who have failed medical management should consider chiropractic care. At Denver Chiropractic Center, our chiropractors know that Active Release Techniques can free up the entrapped sciatic nerve as it passes through the muscles in the hip. In fact, in our experience sciatica is caused by the muscle much more commonly than it is caused by the disc.

Chiropractic for Sacroiliac Joint Pain.

Located in the pelvis, the sacroiliac joint (SI joint) can be the cause of sciatica, resulting in back pain that radiates down the leg. A recent study compared physical therapy, chiropractic manual therapy, and joint injections of corticosteroids. The study found that manual therapy was the best choice for sacroiliac joint dysfunction. The success rate for chiropractic manual therapy was 72%, 50% for corticosteroid injections, and 20% for physiotherapy. Researchers found manual therapy resulted in significant improvement in pain severity, while neither physical therapy nor injections resulted in significant pain relief. In our experience, adding Active Release Techniques treatment makes the chiropractic work even more effective for treating SI joint pain.
