"With Return to Center Force"


A proof of concept animation for a patent on Telemark ski bindings that release laterally in a fall, then return to center with a gravity assist has been produced for Ride In Harmony TM.  
After a fall, when the skier recovers, the foot is raised, the binding rolls back into place for the skier to continue.
           To see how it works for yourself, think of a shoulder or hip joint.  Stand with the arm or leg draped from the shoulder or hip, turn your foot in or out, then relax.  It straightens out. 
            Part of the emerging Holy Grail of Telemark or free heel  skiing, the KAM-HOLDZ TM decoupler releases laterally under pressure, then, rolling back into place with the assist of gravity. This “return to center force” allows the skier to easily resume sking.

 Sequence of Events             Lindsey Vonns ACL Injury
Claimed is fair use of video for educational purposes.
Lindsey came over a rise, a jump, and as she did so, her weight and balance dropped back of the center of the skis, toward the tail.  Note: Hands behind hips, and hips have dropped behind the ankles.
She's in the "back seat". 
  Vonn-Going over the jump
#2 Hands moving up,hips back,ankle straightShe begins to recover. Ideally, the hands would be in front, the hips are over the ankles, and both skis are tipped in the same plane or direction, for the ski to carry the skier in the intended direction.  The center of a functional range of motion.
The hips are still  behind the ankles though, right leg extended and slightly ahead of left. The right ankle is straight, and the calf is against the back of the boot, angleing the tail of the ski toward the snow.
The boot and tail of the ski, from this position will combine to apply forces to the knee when the ski hits the snow.
Because the right hip is inside the right ski, and not squared over it she is about to land off balance back and slightly to the inside or left.
#4 Pre TD hips in back, skitop not visible
#5 The right ski tip rises slightly as the tail of the ski hit
s the snow. Compare with Photo #4 above.
 The right leg is now straight, as it is hyperextended
 by rebound from the tail of the ski into the back
 of the boot, and now the knee can't bend forward.
 This energy will go somewhere.
#6 Ski jets out,starts to roll inward
#6  The top of the ski becomes visible as the ski rolls inward. Follow it's trajectory.
#7 Right ski continues to roll up as the knee collapses, judging by how much of the top of the right ski is visible. 
  ACL #7 as the Rt. ski rolls so does the knee. The top of the ski becomes visible
.#8  Ski continues to roll inward as Lindsey starts to go
down.  Remember, what you see happening to the ski top is
 happening to to the lower part of the right leg.
Kneehas collapsed
#9 The knee has collapsed.
#10 Ouch.  Women have two to ten times the ACL injuries that men do.  There are gender issues for athletes, skiers, and instructors and coaches.
The IOC in a report, identified causes of ACL injuries in women,  and coaching strategies to mitigate them.
Gender issues in general sports include:
Increased risk at the time of the month, due to hormonal changes affecting ligament strength, a smaller notch in the knee, and the knee torques
inward more during impact on landing.
We will have more in this in the next issue.
#11  Lindsey tore the ACL, MCL, and cracked the top of the Tibia, a bone in the lower leg.
It will typically take six months or more to rehabilitate the injury, according to published reports.
And it's a painful rehab, that will put her Olympic
aspirations in Sochi at risk in2014.

RIDE THE SNOW IN HARMONY™ lessons, RIDEINHARMONY™,  AND SHAPED TEACHING™, its teaching method, are consistent with advise and practices about how to avoid the most common major injuries to the knee, as we know them, and we have evolved some of our own common sense practices, to boot.  Oh yeah, that's one of them.  Get the right boot, and learn your size in "ski talk" so you know what you are getting. 
What causes an ACL to shear or snap?  An inward twist of the outside knee, that's excessive or sudden, sometimes in a turn, a fall, or upon landing from a jump.  

What USUALLY starts the excessive internal twist? The turn-side(TM), inside, hand drops back and in, taking the rest of the body with it, while the outside foot is stationary, trapped, or posted in one place.  Know where you are going and point in that direction.

Is this a simplifying things? Yes, but it applies in about seventy percent of the ACL ruptures, the most common major ski injury.

Just beginning to ski, or arriving at a ski area for the first time, here are some things you can put on your side for safety.
ACL Checklist for newskiers: 
      1. Know your size foot and the boot you are given.
                 They should be the same size or tighter, fitting like a glove, to move when your foot does.  Ski Boots are sized in a system called Mondopoint, but you can translate most sizes into standard US sizes easily.  A size 8 in a regular shoe, for instance, is a marked as 26. 2+6=8 so size 26 in a ski boot is equal to size 8 in a reglar shoe.  Getting a larger boot than your foot size, can be like installing loose steering on a car.
2. Turn-side™ hand forward, RIH style. First three lessons, train you to move the hands forward.  A safe practice.  
3. Two footed foot movements. Lesson 4. Tail of the Dolphin   Learn at your own pace on slopes you are comfortable skiing and riding, then work up.
4. Get aligned early in your career - Huh!  If you are knockneed, statistically, your risk of injury is greater. Get a footbed from a qualified technician or bootfitter that supports the inside of the foot against pronation. Your goal is to get support of the edge of both skis at the same time. If you are knockneed you may not be getting that, and it is called being underedged, for purposes of skiing.  Ideally a footbed will provide a,"Prophylactic arrest of inward rotation of the femur" or knee. Because Knees bend better forward than sideways, 
support under the foot, adapted to you, may resist the internal rotation of the femur.
5. There is more but this is a start.  Physical conditioning should be taken into account as you continue. If you have not already been an athlete, you are now.

 Patented use of gravity

   Ride In Harmony™   Founder, Cary Thompson , has 19 claims for patent granted by the US Patent and Trademark Office, for telemark bindings used in free-heel skiing.  The Kam-Holdz™ technology,  operating like a shoulder or hip joint, features a partial release system which pivots back into place with a gravity assist, following a release during a fall.
Cary says he expects new free-heelers to welcome the security of a release system, and stay with it for the enhanced performance that the strategic placment brings to skiing. 
Experience the "Unbearable lightness of skiing", and patented "return to center force" of KAM-HOLDZ™ Technology, with apologies to Milan Kundera.

     It makes sense that the easiest way to learn to ski and ride, is also the safest, and consistent with safe practices.  
     They are not just what your body can be made to do, but what it does with the least effort, because they are natural.
     But are they generally taught in ski schools?  Not always.  That's where RIDE IN HARMONY (TM) and its SHAPED TEACHING (TM) method come in. Anterior_cruciate_ligament
