Woollahra Dental would like to share some information published by the Heidi Dawson  to provide her top five exercises that everyone should be doing. The aim of these exercises is to address common muscular issues that so often lead to muscle imbalances, poor posture and subsequent pain or injury.


Few of us perform exercises regularly with the aim of preventing pain or injury. In fact, few of us perform any exercises regularly with injuries in mind — even ones we have previously been prescribed to help rehabilitate an old injury. Once the pain has gone, the exercises often stop.

As the old saying goes, "prevention is the best medicine," and this is definitely true when it comes to the training and development of our bodies. There are so many injuries I see on a daily basis that stem from the same few causes — causes that can so easily be addressed in just a few minutes a day, before they become a problem or cause a problem somewhere else along the chain.

So, with this in mind, here are my top five exercises that everyone should be doing. The aim of these exercises is to address common muscular issues that so often lead to muscle imbalances, poor posture and subsequent pain or injury.

1. The clam

The clam is an exercise designed to strengthen the abductor and external rotator muscles of the hip, such as gluteus medius and minimus. This exercise is important for a number of reasons, but the most common reason I prescribe it is in knee pain rehabilitation.
If these muscles are weak, it allows the knee joint to fall inward when we are weight-bearing or landing predominantly on a single leg, as occurs when walking, running, jumping, etc. This creates a valgus force at the knee and dramatically affects the biomechanics of the knee joint.
The most frequent complaint caused by this pattern of movement is known as patellofemoral pain syndrome — a condition characterized by a vague pain at the front of the knee which often comes and goes, moves around and is usually worse when walking down hills and stairs.
The reason so many of us suffer with this weakness is because we don't move laterally. Ever. Everything we do is straight forward and occasionally backward (in the sagittal plane as it's known). These muscles specialize in moving us sideways, and as the saying goes "use it or lose it." If we don't train laterally, we can't expect our bodies to do it well when it comes to daily situations.
The clam exercise can help strengthen the muscles which are responsible for preventing the knee falling inwards like this. Here's how to do it:
Lay on your side, knees bent to a right angle, feet together and in line with the spine and hips stacked one on top of the other.
Keep the lower back and pelvis still and the feet in contact, as you lift the top knee up, away from the bottom knee.
Ensure you don't roll backward through the pelvis as you lift the knee. This means the movement will probably be smaller, but it will be isolated to the hip joint.
Slowly return to the start position, under control and repeat.



2. Gluteus maximus isolation

The gluteus maximus is the biggest of the "glute" muscles found in the butt. Its role is to extend, abduct and externally rotate the hip. This muscle is often known as the powerhouse of the hip, and its role is vital within the gait cycle.
However, for too many of us, the Gmax doesn't work as efficiently as it should and becomes "inhibited." This basically means it doesn't fire when required.
The most common cause of Gmax inhibition is a shift in the pelvic position into an anterior tilt. What this means is that the front of the pelvis is pulled down (usually by tight hip flexors — more on this later), resulting in a forward rotation of the pelvis.
This in turn actually lengthens the Gmax and can cause it to "switch off." This places a bigger demand on the hamstrings and other, smaller bum muscles that can then become overworked, leading to injuries such as hamstring strains, lower back and sciatic pain and even calf and Achilles problems.
This exercise is really useful in order to "switch on" the Gmax:
Lay on your front, both legs straight and the leg you want to work turned out a little (so the foot points outward)
Simultaneously lift the whole leg (knee straight) off the floor and out to the side, in a diagonal movement.
Don't lift the leg so high that the back arches — a small lift is sufficient
Rest and repeat

These three movements are all of the ones that the Gmax performs and no other muscle can do all three, so it has to fire here. Repeating this movement pattern helps to re-establish the connection between the brain and the biggest of butt muscles.






3. Scapula stabilizer strengthening
The scapula stabilizers are muscles that connect the scapula (shoulder blade) to the rib cage and spine. They include little gems such as serratus anterior and the lower fibers of trapezius.
Without these muscles functioning efficiently, our scapulas move about all over the place when we move our arms. The scapula is the point onto which many muscles in the upper body attach, and we need this to be a stable base of attachment to produce the most effective and powerful movements we can. 

Without strong scapula stabilizers, you put yourself at risk of injuries such as shoulder impingement and rotator cuff or labrum tears, to name just a few. The scapula stabilizers are also important in maintaining good posture, which in turn can reduce the risk of tight, aching neck and shoulder muscles, neck pain and headaches.
There are several exercises out there that are recommended to work the lower trapz and serratus, and it's hard to pick just one. But this scaption exercise has been shown to produce the combined highest muscle activation of both muscles. Here's how to do it:  

Perform this exercise one arm at a time — hold a dumbbell or the end of a resistance band in one hand
Start with the thumb pointing up and the scapula retracted (pulled back)

Raise the straight arm upward at a 30-45-degree angle in front of the body. Think halfway between lifting the arm straight up in front and straight out to the side. This is the scapula plane.

Lift the arm up above shoulder height, as far as is comfortable and then slowly come back down, maintaining a retracted scapula. Repeat.

There is lots of debate ongoing at the moment concerning the best exercises for promoting scapula stability, and that has made it hard to choose just one. Other ones you could try include a push-up plus and the dynamic hug exercise.




4. Pec minor stretching
The majority of us spend a large part of our day sitting down, hunched over something like a computer, desk, steering wheel, etc. Even with the best intentions, posture often slips into that atrocious curved spine, rounded shoulders position that feels so natural. But constantly adopting this posture can cause problems due to the shortened length of the pectoralis minor muscle.

The pec minor is the smaller of the two main chest muscles (the other being pectoralis major). It attaches to ribs 3-5 and travels upwards to insert into the coracoid process — a forward-facing bony protrusion of the scapula. If shorter in length than it should be, it can effectively pull the shoulder blade forwards, creating a protracted (rounded) shoulder position.

As we learned from the hip flexors and gluteus maximus earlier, shortening on one side of the body leads to lengthening and potential inhibition on the other side. In this case, the inhibition often manifests in the scapula stabilizers (see above).

Stretching the chest muscles in a conventional way doesn't really target pec minor due to it having no attachment on the arm. Therefore moving the arm into extension, abduction and external rotation (as most chest stretches do) will have no effect. Instead you need to find a way of increasing the distance between the upper ribcage (origin) and the scapula (insertion). Cue the foam roller method:
Place a foam roller on the floor and lie on your back, with the foam roller along the length of your spine.
Ensure your head is rested (either on the roller or a pillow) and the knees are bent with feet flat on the floor.
Allow the shoulders to drop down towards the floor and relax.

This reverses the hunched over position we often adopt which leads to a shortened pec minor. It probably won't feel like as strong of a stretch as a hamstring stretch, but it should feel like a subtle pull and like the chest and shoulders are opening up.





5. Hip flexor stretching 

Again, often due to being seated for long periods, tight hip flexors are a common issue. The rectus femoris and iliopsoas muscles at the front of the hip and thigh are in a shortened position when we are seated. If sitting for long periods, this becomes their natural resting length, and this is where the problems can start.
As discussed above, increased hip flexor tone can cause an anterior pelvic tilt. This plays havoc with the way the pelvis moves and affects other muscles such as the gluteus maximus, abdominals and hamstrings, as well as smaller, deeper hip muscles.

Injuries and pain conditions resulting from an anteriorly-tilted pelvis can range from lower back and sciatic pain, to hamstring and groin strains, and even as low as the ankle or as high as the neck and shoulder due to further compensatory biomechanical adjustments.

Stretching the hip flexors regularly throughout the day is a simple way to help reduce this natural shortening:
Kneel on the floor on one knee, with the other foot on the floor in front of you, knee bent to 90 degrees.
Tilt the pelvis posteriorly. This can be achieved by trying to tuck the tailbone underneath yourself or by trying the flatten the lower back.

Hold this tucked pelvis position, as you gently shift your weight forward over the kneeling knee, until a stretch is felt in the front of the hip.

To more specifically target the rectus femoris, perform the same stretch, with the toes of the back leg tucked under the foot — this increases knee flexion slightly and the stretch shifts down the thigh.




Stretching these muscles should be performed regularly, ideally 3-5 times, spread throughout the day to lengthen the muscle after a period of sitting.
This is by no means a definitive list of preventative exercises that any individual may want to adopt. But it is a good starting place for many people who fall into a fairly "typical" daily pattern of sitting for long periods and then undertaking sudden bursts of activity/exercise.

Spending just 10 minutes a day working on these most common imbalances, can save a lot of time (and money) on treating an injury further down the road.

Proper dental care linked to reduced risk of respiratory infections in ICU patients

New research shows vulnerable patients in the Intensive Care Unit (ICU) who received enhanced oral care from a dentist were at significantly less risk for developing a lower respiratory tract infection (LRTI), like ventilator-associated pneumonia, during their stay. The study was published in the November issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America (SHEA).

"Bacteria causing healthcare-associated infections often start in the oral cavity," said Fernando Bellissimo-Rodrigues, MD, lead author of the study. "This study suggests that having a dentist provide weekly care as part the ICU team may improve outcomes for vulnerable patients in this setting."

Brazilian researchers utilized an observer-blind randomized clinical trial design to analyze data from 254 adult patients who stayed in a general ICU for at least 48 hours. Patients were randomized to receive enhanced dental care provided by a dentist, or to receive routine oral hygiene performed by the ICU nurse staff.

Enhanced dental care included teeth brushing, tongue scraping, removal of calculus, atraumatic restorative treatment of caries, tooth extraction and topical application of chlorhexidine corresponding to each patients' needs four to five times a week. Comparatively, regular treatment consisted of mechanical cleansing using gauze followed by topical application of chlorhexidine three times a day.

Patients provided enhanced dental care were 56 percent less likely to develop a respiratory tract infection during their ICU stay compared to the control patient group. Researchers note that enhanced dental treatment, including oral antisepsis routinely performed in ICUs could be more effective in reducing the oral bacteria and help prevent migration of these bacteria into the lungs.

TMJ Next Generation Device FDA Approved for Temporomandibular Joint Disorders

Woollahra Dental would like to share some information published by the AACP written by GAURAV KRISHNAMURTHY to provide information a device (FDA Approved) for Temporomandibular Joint Disorders .

TMJ Health (Farmington Hills, MI) has received FDA clearance for the TMJ NextGeneration Device to alleviate temporomandibular joint disorder (TMJD) pain. TMJD affects the jaw joint, surrounding muscles, and nerves, leading to chronic pain and poor quality of life. According to the NIH, more than 35 million Americans suffer from TMJD, which includes symptoms such as pain in the face, jaw or neck, jaw muscle stiffness, and sharp pain around the ears. TMJD has conventionally been treated with bite splints to reduce the amount of grinding of the teeth that causes the sharp pain. These splints cannot be worn while eating, are known to affect speech, and cause long term damage to the joints.


The TMJ NextGeneration device treats the TM joint pain in the ear canal, which happens to be near the temporomandibular joint. The device consists of two hollow ear canal inserts that rest in the outer part of the ear canal and allow full transmission of sound due to their hollow construct. The device is also easy to remove thanks to the retraction posts that are built into it.  The device is discreet, not noticeable from the outside, and makes use of the dynamic change in the ear canal geometry when the jaw is opened or closed through movements such as chewing and smiling. The device is 20% larger in size compared to the ear canal when jaws are closed, and this change in ear canal space applies light pressure against the walls of the ear canal to encourage the patient to return to the open jaw position while reducing the inclination to clench the jaw. All TMJ Next Generation devices are custom built to match the patient’s unique anatomy.
