5 Simple Exercises to Combat The Effects of Bad Posture

In practice it’s often difficult to get the results we want with regard to spinal correction. The reason for this is the prolonged time they spend sitting. According to the American Journal of Pain Management “Posture effects and moderates every physiological function from breathing to hormonal production. Spinal pain, headache, mood, blood pressure, pulse, and lung capacity are among the functions most easily influenced by posture.” (1) There is also evidence that poor thoracic posture shows “a trend towards greater mortality” as discussed in a study by the Journal of the American Geriatrics Society.

The newest epidemic! Text Neck. Using our cell phones and computers has to some, gotten to the point of an obsessive compulsive disorder of your phone. In practice I see patients texting while on therapies and while walking into the adjusting room. When I come into a room to adjust a patient, they are sitting in the corner and texting! Why do I allow that in my office? I don’t! I repeatedly remind patients that this type of posture is why they are in my office and point out the irony. This is why I say, it’s an obsession!

A recent article by Kenneth Hansraj, MD the chief of Spine Surgery at New York Spine Surgery and Rehabilitation describes that as the head tilts forward its weight effectively goes from 10 to 12 pounds in the neutral position to as much as 60 pounds at 60 degrees of flexion, which is the typical position that we have while using a mobile device. (4)

Over time this forward head position leads to permanent deformation of the structural ligaments of the spine. (5)

In addition to the ligamentous deformation, muscle adaptations such as ‘Upper Cross Syndrome’ always follow. UCS is characterized by tightness of the upper trapezius, levator scapula and pectoral muscles along with weakness of the deep cervical flexors and middle to lower trapezius muscles.

As these postural changes occur with the neck and upper body, our lower body becomes susceptible to adaptions as well. These include weakened back muscles as evident in a study by Sanches-Zuriaga that found a decrease in low back muscle activation after soft tissue creep, suggesting that prolonged or repeated flexion could increase the risk of injury. (6) These findings support the fact that prolonged sitting should be interrupted with breaks in order to decrease this risk along with exercise intervention.

For the purpose of this article the focus will be on the Active Subsystem (spinal muscles) as described by Panjabi in his spinal stability system model. The following five exercises can be used for most patients requiring minimal time and no equipment. These exercises will not only help with preventing the above-described deformation and adaptation risks, but also encourage patients to stand up regularly and perform mini exercise breaks throughout the day.

We will start with the forward head posture as described by Harman and colleagues who found that this position is associated with weakness of the deep cervical flexor and mid thoracic scapular retraction muscles. (7) Additionally, shortening of the opposing cervical extensors and pectoral muscles was also noted. A combination of strengthening exercises for the deep cervical flexors and scapular retraction muscles coupled with stretching of the cervical extensor and pectoral muscles was performed for 10 weeks. The findings of the study demonstrated that a short, home-based targeted exercise program can improve the postural alignment related to forward head posture.

Based on the above findings the following three upper body exercises are suggested given they are ‘low-barrier’ homework for clients that they can perform daily without any equipment.

As described earlier, prolonged sitting and its effect on posture is not limited to the upper body alone but also affects the lower body. Tightness of the hip flexors along with an inhibition of the extensor muscles can lead to an aberrant motor pattern know as “gluteal amnesia” according to McGill. (8) He recommends exercises to enhance gluteal muscle function to unload the back in additional to hip flexor mobility with specific psoas muscle targeting.

Head Retraction

Head-retraction_2Begin seated, or standing, looking forward with shoulders back with good neutral posture. Activate core muscles. Attempt to draw head directly backwards. Maintain level head position. Do not tilt head up or down. Hold for two seconds. Return to start position. Beginners should start with 3 sets of 10 repetitions.

Shoulder Retraction

Begin standing in good posture. Shoulders should be back and head up. Bend elbows to Scap-retraction_1-90 degrees and keep elbows near sides. While maintaining good posture, draw shoulders back squeezing shoulder blades together. A stretch may be felt in the chest and front of shoulder. Do not allow shoulders to raise upward. Hold for 5-10 seconds. Beginners should start with 3 sets of 5 repetitions.

Doorway Chest Stretch

Chest-Stretch-1Place forearm on wall, or doorway, with elbow bent at 90º. Elbows should be slightly

below shoulder level. While maintaining forearm contact, lean body into doorway until gentle stretch is felt in the chest and shoulder. Hold for 20-30 seconds. Beginners should start with 3 repetitions on each side.

As described earlier, prolonged sitting and its effect on posture is not limited to the upper body alone but also affects the lower body. Tightness of the hip flexors along with an inhibition of the extensor muscles can lead to an aberrant motor pattern know as “gluteal amnesia” according to McGill. (8) He recommends exercises to enhance gluteal muscle function to unload the back in additional to hip flexor mobility with specific psoas muscle targeting.

Here two very effective and easy to perform exercises that clients can do during short exercise breaks throughout the day:

Standing Hip Flexor Stretch

Begin standing in front of a chair about 18 inches away. Place one foot flat on the chairHip-flexor_1seat. Slowly allow hips to glide slightly forward until a gentle stretch is felt on the front of straight leg. Hold for 20-30 seconds. Beginners should aim for 3 sets each on each side.

 

 

 

 

 

Glute Hip Bridge

HP1214_2Begin lying on floor, facing up. Bend knees so feet are firmly on floor and arms extended

  1. to sides. Activate core muscles. Lift hips off floor to attain a bridge position with knees, hips, and shoulders in alignment. Slowly return to start position. Repeat for prescribed repetitions and sets. Initially, you may develop some cramping in the back of the thigh. A simple hamstring stretch, before and after, may prevent this from occurring. Beginners should aim for 3 sets.

All of the above displayed exercises are easy to execute and include minimal risks if performed as prescribed. Most important here is the regular execution and mid- to long-term adherence to the program. A calendar that reminds clients of the exercises and allows them to check off performed sets and reps could be a nice motivation for them and helps you track their compliance.
