Solving Work Related Pain in Dentistry

Dentists, Golf & Low Back Pain

-Dr. Bethany Valachi-

You’ve had a tough day in the operatory, the sun is out, your back is aching, and the green is calling.  What could be better than a game of golf to work the aches out?  For some dentists…just about anything!

It’s no secret that over 50% of dentists experience chronic low back pain1.   So prevalent is the problem, low back pain has become a cornerstone that many dental manufacturers use to market their ergonomic products to dentists.  Yet the very sport that most dentists flock to after work, on weekends or at conferences reports low back pain as the most frequent area of pain and injuries among its enthusiasts.  A staggering 62% of amateur golfers cited the low back as the area most frequently injured2.  Is it possible that dentist’s favorite sport may be exacerbating the ‘weakest link’ in their body?

 Many dentists’ favorite sport may exacerbate certain muscle imbalances to which dentists are predisposed, leading to low back pain.

The good news is that addressing two risk factors that contribute to low back pain in both dentists & golfers may help golfing dentists more comfortably continue the sport they love.  These risk factors are flexed spinal posture and poor spinal rotation away from the patient, or toward the backswing side.

The first of these, flexed spinal posture is a common position assumed by many dentists and often difficult to avoid due to varying patient size, poor patient tolerance to reclining, location of the occlusal surface, etc.   Flexing the spine forward over the patient is a risk factor for muscle strains, trigger points, facet arthopathy and disc degeneration or herniation that can result in low back pain1.

Golfers with low back pain tend to flex their spines more when addressing the ball3, which tends to limit the amount of spinal rotation. Poor conditioning of the deepest abdominal stabilizing muscles, the transversus abdominis, has been shown to contribute to low back pain4, and will predispose dentists and golfers to a slouched working posture.

To avoid this damaging posture, both dentists and golfers should make it a habit to actively pull the navel to the spine (which activates the transversus abdominis muscle) and pivot forward from the hips, not the waist, whenever leaning forward.

Engaging the transverse abdominal muscles in this manner helps stabilize and protect the lumbar spine, and facilitates proper pivoting at the hips both in the operatory and on the green5,2.  Not only should the deep abdominal muscles be the target of a strengthening program for dentists and golfers to decrease low back pain, but also the other trunk stabilizers: quadratus lumborum, lumbar multifidus, erector spinae and oblique muscles.  The swiss exercise ball is one excellent way to target these groups, however the golfing dentist should also progress to standing exercises that are more functional to the sport.

Spinal rotation is also difficult for most dentists to avoid in the operatory.  One study showed that right handed dentists leaned forward, to the right & rotated to the left for two-thirds of their working hours 6.  Dentists who repeatedly postured this way had the highest incidence of low back pain, and also tend to have less spinal rotation to the right (away from the patient).  Repeatedly twisting the trunk in one direction (i.e. toward a delivery system or a patient) can also lead to the development of muscle imbalances that cause low back pain7.

Likewise, the body mechanics of right handed golfers somewhat simulates dentists in the operatory: leaning forward, and rotating to the left.   Golfers with low back pain tend to have less flexibility with trunk rotation3, which can cause compensatory movements in the spine, hips or shoulders2.

The golfing dentist should incorporate specific trunk rotation exercises, especially stretches toward the backswing side (or ‘away from the patient’), as this is the direction that is most problematic for both populations.   Also of importance is avoiding a muscle imbalance of the trunk rotators (oblique abdominals) by targeting the oblique abdominal muscles in a strengthening program.  For this exercise, use a golf club threaded through the elbows, keep the back straight and pivot forward at the hips.  Perform slight rotations toward the backswing side–the weakest side for most dentists.

Although the sport of golf may exacerbate certain muscle imbalances to which dentists are prone, you need not give up the sport you love.

Dr. Valachi’s CE Video Course, Home Exercise for Dental Professionals contains specific stabilization exercises for dentists who golf.
