What I’m about to tell you is gonna change your Life forever. Are you really sure you want to know it?
WHAT IS TECH NECK?
Tech Neck is the term used to describe the injuries and pain sustained from looking down at wireless devices.
Tech Neck Symptoms include:
Chronic Headaches Upper Back Pain Shoulder Pain Neck Pain Curvature of the Spine

IT'S TIME
In 2013, 1.91 trillion text messages sent. Smartphone used 3.6 hours a day or about 1,300 hours a year High school students spend 5,000 hours a year forward flexed. Kaiser Family Foundation found that 8 to 18 year olds spend
7.5 hours on tech "entertainment media". Smartphone data usage tripled from 2010 to 2011. Tablets users use 3.4 times more data than Smartphone users.

“Prolonged muscle tightness leads to fatigue, which ultimately decreases the force available to meet postural and movement demands”

Inefficient breathing could result in muscular imbalance, motor control alterations, and physiological adaptations that are capable of modifying movement.
Results demonstrate the importance of diaphragmatic breathing on functional movement.

50-70 million US adults have sleep disorders.
Most common OSA: blockage of the airway in the throat, closing off air supply and leaving the sufferer without air for up to a minute.
This can have significant outcomes: HBP/heart disease, stroke, depression…
Studies show that sleeping on ones back with high pillows puts the head forward closing off or restricting the airway.

Trigeminocervical Nucleus (TN)
A main factor affecting nerves surrounding the Trigeminocervical Nucleus is the biomechanical aspects of the upper cervical spine.
Postural changes stimulate nerve endings connecting to nucleus. This happens through irritation of the nerves themselves, or
decreasing the level of inhibition of the nucleus itself.
Chiropractic care, specifically cervical spine adjustments, results in inhibition of triggering function mechanisms and ultimately results decreased central sensitization.

mortality risk increased up to 64%. Hypothesis slumping posture causes decrease
in the respiratory index and poor posture therefore creates a decrease in health.

Strengthening Posture to Strengthen Motion
Posture and Motion are two sides of the same coin and both affect how we age.An effective protocol to address one must also address Balance, Motion and Alignment.The 5 Posture Principles is a framework to understand Bio-mechanics.

CHANGES IN UPPER-EXTREMITY MUSCLE ACTIVITIES DUE TO HEAD POSITION IN SUBJECTS WITH A FORWARD HEAD POSTURE
J Phys Ther Sci. 2015 Jun; 27(6): 1739–1742. Published Online 2015 Jun 30. Doi: 10.1589/Jpts.27.1739 Pmcid: Pmc4499973
The results corroborate the clinical notion that postural alterations related to an FHPRS can change scapular kinematics and muscle activities in individuals with such a posture.
Therefore, recovery of normal functions of the UT and SA plays an important role in correcting an FHPRS.
RAMESH BALASUBRAMANIAM PhD
“The control of standing is a complicated task that involves the action of muscles distributed over the whole body. Forces arising from gravity, external events or our own actions all tend to disturb the unstable equilibrium that preserves posture. For the central nervous system the problem of standing can be cast in terms of finding appropriate relations among body segments to maintain the desired position of the body as a whole with respect to the environment.
The control of upright stance involves predictable and unpredictable perturbations in the interplay of perceptual information, attention and cognitive processes in the control of standing."

Standing
RENE CAILLIET, MD
“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.”

Contracting muscles strengthen as they
are used, and unused muscles weaken.
Once a muscle contracts, it remains
shortened unless something else
stretches it.

POSTURAL DISTORTION
Physiologic Compromise of a Spinal Misalignment Complex
1. Unequal load creates increased load on one of the facets2. Elastic deformation of the muscles and tendons
a. Muscles: first to weaken and the first to heal. It takes 6 hours for atrophy to begin. Once atrophy begins, you lose 1.5% of muscle mass per day of non‐use
b. Tendons breakdown: unequal load of the muscle‐tendon junction, causes tendonitis
3. Plastic deformation of the ligaments (which is more likely to become permanent) a. Ligaments change due to the load applied. Loss of muscle tone decreases joint
tension and increases the load to the ligaments

POSTURAL DISTORTION
Physiologic Compromise of a Spinal Misalignment Complex
4. Cartilage most severe damage can occur; heals the slowest and the least. Nutrition is critical for repair of cartilage
5. Vertebral discs degenerate causing decreased rotational torque. The spine may suffer from 25% less rotational ability at the effected joint complex
6. Spinal nerves demonstrate a lower threshold, meaning they fire easier.
7. Nerve pathways become de-facilitated with restriction, and the associated body part becomes weak and clumsy

POSTURAL DISTORTION
Physiologic Compromise of a Spinal Misalignment Complex
8. Vasculature becomes compromised causing hypoxia in certain tissues, and decreased circulation
9. Osteophyte formation: Adhesions and bony degeneration. Wolfe’s Law states that any abnormal stress to the bone creates bony abnormalities
10. Osteoarthritis or DJD is caused by improper biomechanics and mechanical stress of joints due to weight bearing forces or repetitive activities
11. Abnormal Stimulation to Brain: due to Joints abnormal movement result in abnormal stimulation by the surrounding muscle spindles. a. CNS: changes not controlling the movement of that spinal segment properly. Motor
control and stability is different at this level
