"BEST AVAILABLE EVIDENCE"

​

​

The term “Best Available Evidence” in research circles means that to date,

this is the most accurate and current information in the scientific community.  

 

 

This research study (medically based) did just that by incorporating the following firsts:

​

• We were able to measure via the IPecs device the actual force’s being applied to the prosthetic

• The sampling rate, quantity and accuracy of the data collected went through empirical review from statisticians to ensure the collection method was not contaminated

• Incorporating Trackman (golf radar system) we had validation of the ball’s flight and distance to ensure accuracy of ball flight performance

 

By combining these steps we were able to validate that we did reduce deforming forces on the knee of the athlete and in most instances did not lose golf ball performance (carry distance), and in many cases increased both (carry and total distance) of ball flight performance.

Results of the Axial Socket Reaction Moments (ASRM)* ASRM explained - Ground Force Reaction as measured on the prosthetic through all 3 planes of motion (transverse, sagittal and frontal) at the socket (join to the femur).  Axial, this is the line of force. Think of a screw driver in the ground and you are turning it from the handle, your hand is moving around the axial; this is the line of force being measured.

One item we would like to point out here. It is documented that for new motor skills (neurotoxicity /muscle memory) to be retained by the brain and the body, it takes 40 hours of practice for this new skill to become a new learned motor skill retained in muscle memory.   Subject one had only 2 hours of training while subjects two and three had 4 hours of training.

Golf Ball Distance – as measured by Trackman

​

Let’s be honest and as I am a golf player myself, I would most likely not change to the new “Athletic Stance Swing” if it decreased my distance. Period end… I would just play through the pain.  At a minimum, the new stance has to let the golfer hit the ball just as long as the traditional swing.  That is why we were so thrilled to have Trackman as our corporate sponsor during our study.  No ambiguity, we simply have the numbers.

​

Results Summary:

​

Before you open the PDF - here are the results.  This subject F3 (subject 1 in the ASRM above), hit consistently longer with the new stance.  As an amputee golfer the new stance gives him a larger and stronger platform to generate power. The new swing plane also allows better consistency & control of the club itself, delivering the ability to hit the ball on the down swing with more impact (as the bottom of the swing is now off the front shoulder) and lastly; having the ball placed off the front foot, enables a repeatable process that does not require the ball to move within the stance itself.  

 

The other two subjects (two and three from the ASRM) performance was not as consistent as subject 1, their results were as follows:

Subjects two & three  - performed better with mid-iron & pitching wedge with the Athletic Stance Swing and better with the driver in the traditional stance.
