Using BODITRAK To Identify Asymmetry In Standing Posture

Dr. Peter Mackay recently demonstrated how he uses BODITRAK in his clinic to identify asymmetry in standing posture.  It’s one of the most simple assessments a clinician can perform, but effective in revealing a left or right side bias.

“Over the past decade we have stressed the need to assess movement screens but we should not overlook the postural exam, especially with the help of technology. Combining the results of MRI and X-rays (pathology does not lie) with BODITRAK data gives us more information for determining a plan.” – Dr. Peter Mackay

In this video, Dr. Mackay is assessing Shawn Cox, the Director of Golf at the Grand.  As you can see, Shawn presents with a right side bias of roughly 57%.  This is especially common in athletes who play a sport that predominately turn in one direction such as baseball, tennis and golf.

“When analyzing postural imbalance on BODITRAK we can identify myofascial restrictions which correlate with the pattern. For example the lateral pelvic shift is consistent with gluteus medius stretch strain/weakness on the same side. There is also overactivity and relative shortening of the adductor group on that side. It is important to realize that this “default” postural pattern may change significantly with motion. On the other hand if there is true pathology, as in an arthritic hip with reduced flexion, the dynamic screen will demonstrate the dysfunction.” – Dr. Peter Mackay

By performing assessments on BODITRAK, patients are able to quantify their movement or posture.  A lot of data available to athletes requires them to recall how they FELT during an athletic movement.  Think about a golfer seeing their kinematic sequence, ball flight data on a launch monitor or even trace on BODITRAK.  While the technology offers immediate feedback, it’s not real-time feedback.

By standing on BODITRAK and observing pressure data in real-time, patients see the difference between real and feel.  If chronic muscle tightness causes an athlete to favor one side, they eventually recalibrate what they think is “balanced.”

“In the case of Shawn Cox, we have a left handed golfer with a right acetabular labral tear, failed single leg balance, unstable side planks bilaterally and loss of hip flexion /internal rotation. BODITRAK helps us measure his imbalance, monitor his squatting bias and utilize single leg exercises while challenging triplanar motion in the ankle.” – Dr. Peter Mackay
