​You may have heard the comment, “If there’s no damage to the car, then there’s no injury.” Unfortunately, that does not always seem to be the case.

There are MANY factors that affect the dynamics of a collision and whether or not injury occurs. A short list includes: vehicle type and design, speed, angle of collision, momentum, acceleration factors, friction, kinetic and potential energy, height, weight, muscle mass, seat back angle and spring, head position upon impact, etc.

Consider Sir Isaac Newton’s Third Law of Motion: “For every action there is an equal and opposite reaction.” This law applies to a car accident at any speed. Using the analogy of hitting a pool ball into the corner pocket straight on, when the cue ball stops, its momentum is transferred to the target ball which accelerates at the same speed…hopefully into the corner pocket!

This example is not quite the same as an automobile collision because the energy transfer is very efficient due in part to the two pool balls not deforming (crushing or breaking) on impact with one another. If either ball did deform, more energy absorption would occur and the acceleration of the second ball would be lower.
In fact, in the United States, vehicle bumpers are tested at 2.5 mph with impact equipment of similar mass with the test vehicle’s brakes disengaged and the transmission in neutral. National Highway Transportation Highway Safety Administration (NHTSA) vehicle safety standards demand that no damage should occur to the car in this scenario.
However, energy transfer occurs very quickly and with a greater amount of force when there is no vehicle deformation (damage). As a result, a greater amount of energy (described as G-force) is directly transferred to the occupants inside the vehicle—increasing the risk of injury. A 1997 Society of Automobile Engineers article provided an example in which the same 25 mph (12 m/s) collision resulted in a five-times greater force on the occupants of the vehicle when the crush distance of the impact fell from 1 meter to .2 meters.
So be aware that even low-speed impacts can still place quite a bit of force on your body, even if the bumper of your car doesn’t have a scratch on it.

Can Carpal Tunnel Be Prevented? 

~ Dr. Robert Speirs DC ~ Leave a comment

​Prevent

Carpal Tunnel Syndrome (CTS) is a VERY common condition where the median nerve is compressed or squeezed as it passes through the wrist. One reason that it’s so common is because MANY daily activities require fast, repetitive use of the fingers, hands, and arms, and the friction of the rapidly moving muscle tendons inside the tunnel results in swelling and compression of the nerve. So, can CTS really be prevented?

There are many factors associated with CTS, and some risks can be prevented. For example, some conditions like diabetes, rheumatoid arthritis, and IBS increase the risk of CTS. Therefore, it would be safe to assume those who better manage such conditions would have a lower risk for developing CTS.

Due to the many factors associated with CTS, there is no “one size fits all” when it comes to treatment and prevention of CTS. With that said, here are some VERY effective methods:

1)  Ergonomic workstation modifications: Altering the work space (monitor height, keyboard/mouse style, different chair, chair/desk height, etc.) to reduce the number and speed of movements needed to perform commons work tasks.

2)  Rest periods: Insert “micro-breaks” into a busy task. Combine breaks with stretching exercises of the wrist/hand/fingers and vary job tasks between fast and slow repetitive types.

3)  Exercise: Shake the fingers and hands, lean back in a chair with the arms/shoulders stretched back (“Brugger’s Exercise”), move the neck (chin tucks, rotations, etc.), bend the hand/wrist backwards on a wall or the desk’s edge, self-massage and deep tissue release of the forearm and hand muscles. Do regular aerobic exercise (walking, swimming, biking, etc.) several times each week.

4) Posture: Sit up straight, elbows about 90° on height-adjustable arm rests or comfortably at the sides, forearms parallel to the floor; knees level or slightly lower than the hips, feet flat on the floor or on a footrest or box, if needed. Place typing materials at eye level / avoid prolonged head/neck rotation. Use a wrist rest for the keyboard and mouse, and use a headset when on the phone.

5)  Reduce hand tool forces: Choose a tool that allows the wrist to remain neutral. Avoid side to side and flexion/extension wrist positions—especially if they’re prolonged! Tool handles should NOT dig into the palm of the hand or the wrist, and should not have sharp edges. A textured handle can improve grip. Minimize vibration from power tools. Wear shock absorbing gloves. Avoid cold work environments and cold tools.

6)  Diet: Cut down on caffeine and smoking. Avoid obesity—a known risk factor of CTS! Consider an anti-inflammatory diet (Paleo, Mediterranean).

7)  Splints: A wrist cock-up splint at night prevents prolonged faulty positions and REALLY helps!

This is a partial list of preventative measures that can REALLY help. Doctors of chiropractic treat the WHOLE person and can teach you the right exercises, ways to modify your diet, offer manual therapies and modalities, and help guide you in your self-management of CTS, as this can be a lifelong affliction. A multi-modal treatment approach generally works best!

Trigger points in the pectoralis minor muscle.

~ bryancobb ~ Leave a comment

The pectoralis minor is a small strap like muscle that is underneath (deep) to the pectoralis major. It originates on the third to fifth rib, near the costal cartilages. It’s insertion is on the coracoid process of the scapula. It acts to draw the scapula forward, downward, and inward at nearly equal angles ( think of rounding or shrugging your shoulders forward). This muscle is very often shortened and tight in people due to the high prevalence of desk jobs. This muscle pulls the shoulder blade forward resulting in the muscles in the back(rhomboid and mid traps) being chronically strained. Trigger points that form in the pec minor primarily refer pain over the anterior chest and shoulder, with spillover down the medial arm. Trigger points in the left side can mimic angina.

The Bird Dog

Bird Dog

Today we are going to look at one of the most effective exercises to protect your lumbar spine from discogenic injury, the bird dog. A great way to work on both posterior chain and rotational stability, the bird dog is safe, effective and simple.

  • Get on your hands and knees (four point position) with your knees and hands, hip and shoulders width apart.
  • Your back is in neutral position (slightly arched) and your chin must be tucked in.
  • Activate your lower abdominals (transversus abdomini) by bringing your belly button inward and by activating your pelvic floor muscles 20 to 30% of maximal contraction.
  • Maintain a steady abdominal breathing while you simultaneously lift one leg backwards and the opposite arm overhead keeping your back in neutral position.
  • Return to the initial position and repeat with the other leg and arm.

2 sets of 10 reps as part of your regular core/stability routine will have you well on your way to a life-proof low back!

Trigger points in the pectoralis Major muscle.

~ bryancobb ~ Leave a comment

The pectoralis major or “pecs” is commonly thought of as the chest muscle. It originates on the clavicle, sternum, costal cartilage , and the external oblique aponeurosis. It inserts on the intertubercular groove of the humerus. Its main actions are to adduct the shoulder and to internally rotate the humerus. This muscle gets chronically shortened by a rounded shoulder forward posture such as from prolonged sitting. Tightness in this muscle can cause strain in the rhomboids and traps. When trigger points form in this muscle they refer pain into the anterior shoulder, as well as the anterior chest and medial aspect of the arm. Trigger points in the pecs can also cause nipple hypersensitivity. Trigger points in the left pec muscle can mimic heart pain.

Why am I so dizzy after my whiplash?

~ Dr. Robert Speirs DC ~ Leave a comment

Migrane​

Whiplash, or better termed “Whiplash Associated Disorders” (WAD), is a condition that carries multiple signs and symptoms ranging from neck pain and stiffness to headache, confusion, ringing in the ears, and more. But can WAD cause dizziness? Let’s take a look!

Dizziness is a general term that is used rather loosely by the general population. We’ve all experienced dizziness from time-to-time that is considered “normal,” such as standing up too quickly or while experiencing a rough flight.

Often, dizziness and problems with balance go hand in hand. There are three main organs that control our balance: 1) the vestibular system (the inner ear); 2) the cerebellum (lies in the back of the head); and, 3) the dorsal columns (located in the back part of the spinal cord). In this article, we will primarily focus on the inner ear because, of the three, it’s unique for causing dizziness. Our vision also plays an important role in maintaining balance, as we tend to lose our balance much faster when we close our eyes.

It’s appropriate to first discuss the transient, usually short episode of “normal” lightheadedness associated with rising quickly. This is typically caused by a momentary drop in blood pressure, and hence, oxygen simply doesn’t reach the brain quick enough when moving from sitting to standing. Again, this is normal and termed “orthostatic hypotension” (OH).

However, OH can be exaggerated by colds, the flu, allergy flair-ups, when hyperventilating, or at times of increased stress or anxiety. OH is also associated with the use of tobacco, alcohol, and/or some medications. Bleeding can represent a more serious cause of OH such as with bleeding ulcers or some types of colitis, and less seriously, with menstruation.

The term BPPV or benign paroxysmal positional vertigo, has to do with the inner ear where our semicircular canals are located. The canals lie in three planes and give us a 3D, 360º perspective about where we are in space. The fluid flowing through these canals bends little hair-like projections, which are connected to sensory nerves that tell the brain about our spatial position. If the function of these canals is disturbed, it can mix-up the messages the brain receives, thus resulting in dizziness. Exercises are available on the Internet that can help with BPPV (look for Epley’s and Brandt-Daroff exercises).

DANGEROUS causes of dizziness include: HEART – fainting (passing out) accompanied by chest pain, shortness of breath, nausea, pain or pressure in the back, neck, jaw, upper belly, or in one or both arms, sudden weakness, and/or a fast or irregular heartbeat.

STROKE – sudden numbness, paralysis, or weakness in the face, arm, or leg, especially if only on one side of the body; drooling, slurred speech, short “black outs,” sudden visual changes, confusion/difficulty speaking, and/or a sudden and severe, “out of the ordinary” headache. CALL 911 (or the number for emergency services if you’re outside the Canada) if you suspect you may be having a heart attack or stroke!

The Best Piece Of Fitness Gear?

For my money I still believe that the classic TRX suspension trainer is the best piece of fitness equipment out there. Easy to use, super effective, safe, compact and scalable. All fitting into a little bag you can throw in your backpack or purse to take with you.

We have kids as young as 7 using it (my kids want to “work out” with us but are too young for weights, kettlebells and treadmills. The TRX is a great way to have them as part of your fitness routine in a safe way) and adults in their 70’s too (both my parents use the TRX to stay strong and limber in the retirement years).

With dozens of exercises and workouts at your disposal online you’ll never get bored and never find it “too easy”.

Lumbar Spine Stabilization

~ Dr. Robert Speirs DC ~ Leave a comment

L Spine Stabilization

This is a great way to increase the stability of your lower back.

  1. Lie with your stomach over a therapeutic ball while stabilizing yourself with your feet and arms and keep your head in line with your body.
  2. Tighten your abdominal muscles to flatten the spine by pulling your belly button towards your back and hold the contraction throughout the exercise.
  3. Bend one knee and lift it up towards the ceiling.
  4. Lower the leg and repeat on the other side.

 

Trigger points in the rhomboid muscles.

~ bryancobb ~ Leave a comment

This is another common muscle to get trigger points. It originates on the spinous processes of the T2-T5 vertebrae. It inserts on the medial border of the scapula. It’s main actions are to adduct the scapula pulling it back toward the spine, and to rotate the glenohumeral joint downward. This muscle also prevents wining of the scapula. This muscle is often overloaded by a sitting posture where the shoulders are rolled forward such as when using a computer. The Rhomboids are often weak and under trained in people. Trigger points in this muscle cause pain and ache in the upper back between the shoulder blade. Strength trading for this muscle is necessary to help prevent postural overload.

When Are My Shoes “Done”?

~ Dr. Robert Speirs DC ~ Leave a comment

Running shoes need to be replaced every 250 miles. There are three basic options:

 

✓ Motion Control Shoes – Designed for people with low or no arches, these shoes are for runners who strike the ground on the outer edge of their foot. Avoid overly stiff shoes as these decrease you perception of ground strike and lead to new injuries.

 

✓ Stability or Neutral Shoes – Designed for people with normal or average arches and running mechanics. The shoe contains some cushioning to absorb shock and prevent injuries and some rigidity to avoid pronation.

 

✓ Cushioned Shoes – Designed for people with high arched feet. Their footprint will typically leave a thin band along the foot’s edge. As they run weight is distributed from heel strike to the outer edge of the foot and small toes that bear the brunt of “lift off.” This shoe is more flexible and absorbs the shock created by the lack or rotation (under-pronation) created by their running style.
