Solving Work Related Pain in Dentistry

Exercises that May be Worsening Your Health!

by Dr. Bethany Valachi, PT, DPT, MS, CEAS

When dental professionals come to understand the muscle imbalances to which they are predisposed, the proverbial ‘light bulb’ often appears…”Ah, that’s why I always had pain after that exercise.” Here are some of the most common muscle imbalances to be aware of…..while not a problem for the general population, these exercises can throw the dental professional into the vicious pain cycle!

Unbalanced Muscles – Exercise Caution!

Primary shoulder girdle stabilizing muscles.
Muscles that compensate when stabilizer muscles fatigue.
Vertical row exercise.

In order to perform the precision tasks of dentistry, the arms must have a stable base from which to operate.  For example, dentistry requires excellent endurance of the shoulder girdle stabilizing muscles, for safe shoulder movement and working posture (Fig 1, left).   These shoulder stabilizing muscles tend to fatigue quickly with forward head, rounded upper back and elevated arm postures-all  commonly seen among dental professionals.

When these muscles fatigue, other muscles must compensate and become overworked, tight and ischemic (Fig 1, center).  One exercise that can easily exacerbate this painful imbalance is the vertical row exercise (Fig. 1, right).

Another common imbalance among dental professionals is in the shoulder, caused by over-strengthening the deltoid and supraspinatus muscles.  These muscles already tend to be strong in dental professionals due to frequent shoulder abduction (lifting the arms away from the sides of the body while working).  This imbalance can cause improper movement of the shoulder joint and scapula, causing impingement and pain.

 

Shoulder abduction machines often cause painful imbalances.
Deltoid lifts can be very damaging to your joints and spine.

Another imbalance often occurs between the pectoralis muscles, which become short and tight when working in front of you for prolonged periods of time and the interscapular muscles.  Bench presses and push-ups (Fig. 3) can put you on the fast track to worsening this imbalance, resulting in rounded shoulder posture, impingement or thoracic outlet syndrome.  Push-ups also require weightbearing through an extended wrist, which is a high risk position for female dental professionals.   Full sit-ups target the rectus abdominis, and when done excessively, full sit-ups can cause flattening of the lumbar spine.  The last half of the full sit-up strengthens the hip flexors–something that dental professionals should avoid!  Rather, dental professionals should be focusing on strengthening the transverse abdominal muscles to stabilize and protect the lumbar spine.

Some Pilates & Yoga Exercises Should be Modified or Eliminated Entirely!

Push-ups strengthen the pectoralis muscles, which are already short and tight in dental professionals.
Full sit ups can cause flattening of the lumbar spine when done in excess.

 

 

 

 

The ‘superman’ exercise places high compressive loads on the lumbar spine and should be avoided by persons prone to low back pain.
The ‘bicycle’ exercise places an unsafe compressive force on the cervico-thoracic junction, and should be eliminated altogether.
