Addressing knee problems in Classical Tai Chi






Hello all, 

"I am new to Tai Chi, (practicing for the last two weeks!) and I've been trying to learn the square form from the DVD, before tackling the round form. 

I can do the first two forms (preparation and raise hands)but am encountering some difficulty in the transition to the third (Hand strums Lute).

Obviously I am doing something wrong, since Master Hwa does this effortlessly in the DVD. I did check that my weight is fully on my right leg and the left leg is 'empty'. I'm sure my body is stiff (which is why I'm doing Tai Chi!), but I can't figure a way to put feet 90 degrees to each other without straining the weight bearing knee.

If anyone has encountered this before, I'll be very grateful for any suggestions."

Thanks in advance,
A student


"It is the heightened negative sensations that enable the practitioner to sense that he or she has the wrong posture or body structure, such as a concaved back putting undue pressure on the lower back, or an out turned back foot which creates a twisting force in the knee, etc. It is these negative sensations that guided me to improve my form movement. No teacher can correct every movement of the student. It is up to the student using his own feedback sensation to alert that something is not right. I always wonder why so many people practice tai chi with such bad posture oblivious of its consequences. As Sifu Jim Roach pointed out in "One Yin, One Yang" Blog article that such feedback sensation needs to be cultivated. It may not be something born with it." on One Yin, One Yang of October 3, 2011

3. "Hand Strums the Lute...."
“Pay special attention to the feet. This is the first form that subjects the students to complex feet movement. It is easy to be distracted by the complexity of the upper body movements and neglect the details of the lower body”

  • In further consideration of the above instructions and what you say about “torque in the right knee but nothing very painful”.  
  • I would spend more time paying attention to details of the lower body and forego the upper body movements for now.
  • In other words, do the stepping, weight shifting of the square form without raising the hands and arms whatsoever, put your hands by your sides. 
  •  Do this just as though you were doing the basic walking.
  • The basic walking is the lower body work of the square form. 
  • The square form takes the lower body work and adds turns, weight shifts and complex foot movement, which is why:
  •  You may wish to consider holding onto a post as you practice these lower body movements, just as Master Hwa teaches in one of the Youtube videos.  This will stabilize your upper body and further lessen the chances of becoming uncomfortable.
  • I do this “post” work, even such complex foot movements with my students and they seem to relish not subconsciously worrying about their balance.
        There is not much discussion in Tai Chi instruction “out there” with such iteration about protecting the knees as Master Hwa provides in the DVD series. For the most part, however, he addresses the mid size stance which is an optimum choice for most entering students.

            
Difficulties in turning from the heel is often due to the following factors:
        Too large a stance or incorrect/insufficient knee bend. 
           
          Finally, much more consideration should also be given to your step size

·      
       
I      If you had a knee problem before, your first order of concern is to protect your knee. When you are comfortable with your knee and can do the lower body form movement found first in the walk, or doing form movements sans the upper body, then add upper body work.

A Golden Rule with many facets..."do not hurt yourself"




The Youtube Video along with a transcript under the video (the small square icon looks like stacked paper), the  photo above,  and the following is excerpted from Master Stephen Hwa's comments in a 2011 workshop.  The subject had to do with internal discipline but also delves deeply into body structure and the benefits of practicing.  You will have to link from here to the Youtube video on the subject and can either follow along with what is written here or from the "Description" at the Youtube video itself.  

One of the things that occurred to me as I was editing the video for publication was a new perspective on something I had read in "Uncovering the Treasure".  A golden rule that Master Young gave to Master Hwa was that the knee does not extend over the toe.  It occurred to me that the knee can (incorrectly and harmfully) extend over the toe in more than just the forward direction, it can extend over from a "torque" that Master Hwa speaks of in the video and here.  In other words, it can extend over the side of the toes as well as the front, can it not?  All of that resulting from a thoughtless rotational action on what should really be a simple understandable concept for a healthy stable knee joint.

Sifu James Roach

Workshop 2011, Buffalo State College:

"If you stick to this Classical Tai Chi program there will be a big improvement to the back. This is an important component about the back.  The back will respond to stretching  if you give consistent opportunity to stretch and the lower back will improve.  If you tuck your chin in correctly, you will also stretch your cervical spine as well. So the parts of this stretch are equally important. This may very well work to correct cervical spine problems or such things as a “knot” in the back of the neck.

So as relating to body posture, that is one of the central themes.  In this regard you will be able to have the energy transfer from the neck down to the heel. The energy can flow this circuit without outflowing to the middle of the body, like the lower spine for example.  This will transmit all the force to the ground in one uninterrupted  flow,  it will not be transmitted to just the lower back where it can cause problems.

The other important body posture is referred to in Tai Chi  as “Hand follows the foot, elbow follows the knee and shoulder follows the hip”. In other words we do not turn by only using  half of the upper body and neglecting to turn the lower.  The turning power has to come from the waist and the entire muscles of the back.  There is a vast majority of Tai Chi schools that do not follow this rule.

There is a question which has been raised in the past about this rule.  Where do we apply this rule?  Because we also have turning moves as well.  This is relatively easy to see in the form but when you are doing applications with other people, or as in “free form”, when is the rule applied?

I searched the entire form and found there is consistency and explanation actually. It is easy to explain and there are many different levels of explanation for this:  Any movement that you where you are going to cause a torque (a twisting force that tends to cause rotation) (the danger of which comes from “shear force” a stress which is applied parallel or tangential to a face of something  as in this case a knee or ankle) in the knee or ankle, then you use the rule.   In other words, any time you have the potential for a twisting force that tends to cause rotation, key words twisting force which causes rotation to a knee or ankle. 

This is surprisingly such a simple concept but people are not following it. One of the best examples of this I can use is a golf swing.  Do you see the torque in my knee and ankle?  This why golfers have ankle problems, lots of people have knee problems.  I am not a golfer so I cannot say but certainly if you “hand follow…” the foot out you will not have that problem.  Whether you can do that as a golfer or not, I do not know.   However, if you look at our form and in every case, every  instance, it is always following the rule to the letter.  Now if you examine the “half body” turning movement, there is no torque down at the knees or ankles.  So this type of turn is allowed because you see I do not have to turn my foot with it.

Now this is certainly for health viewpoint.  For martial art viewpoint, it is this way and you have much more power.  More power than the leg lagging behind, in which you are fighting yourself.  The torque force pulls your body backward while you are attempting to turn forward.  

On another level, remember at one time we came back to considerable argument regarding “turning at the waist vs. turning at the hip”.  People have said that “turning at the hip has more power than turning at the waist”.   Well, you see, again that turning at the hip is torqueing your knee and ankle.  WELL, YOU MAY SAY YOU ARE GETTING YOUR OPPONENT ON THE GROUND BUT EVENTUALLY YOU WILL HURT YOURSELF, YOU ARE ALREADY HURTING YOURSELF.

After all, when you learn martial arts, the first principle is that you do not want to hurt yourself.   Otherwise, your opponent can wait just a few years for the damage to set in (laughter).  Somehow not hurting yourself and delivering the power really coincide with each other.   If you don’t hurt yourself, you can deliver more power.   Now there are people, who argued with someone here in the past, now they are very strict…STUDENTS HAVE GOT TO TURN THEIR HIP.

If you are a young person, you can get away with all kinds of movements for awhile.   You see this in golfers when they are young but when they get older they are really hurting themselves.  Sooner or later this will take its toll."

More methods for training the basic walk of Classical Tai Chi




I am very grateful to my teacher for the work he did in making this video.  Over the years of practice and training students I have discovered a few other methods and observations that can be used for the training. In Classical Tai Chi the basic walk is done with the knees slightly bent and remaining so. When practicing the first lesson of Classical Tai Chi Walk one should first look to stretching the neck up.  Students should also check that they are not watching the ground to see if their feet are correct.  Check the position of the feet  in one of the exercise methods we outline below wherein the student will stand in one spot. The position of the legs can also be checked in this “one spot” method, thus making sure that the thighs line up when the student sits back, or the knee does not go over the front toe when the student leans to the front.  As the student progresses they should find they are automatically stretching the head up and looking forward as well.  This is an important part of the “lean” forward posture where unless checked a student will watch their feet. When one “sits” back, the body should be vertical and perpendicular to the floor

As training progresses, the student will keep the body weight back when they are dropping the foot.  It is a sign of a perpetual beginner to have the body weight lurch when the foot takes a step. The foot pushes down until it is completely flat on the ground then used either to pull the body forward or back.  Until the foot plants firmly the body does not move and hence the body moves in a pulling from one weight shift to another.  One wants to learn to recognize,then end, any kind of rocking action with either lead foot as the weight shifts.  I show this “rocking” in my class by students pulling me  by the arm AS my  lead foot is being planted, then pull me  AFTER my lead foot plants.  This also holds for stepping backward and plant the foot by actually touching the heel to the floor first.  Eliminate the rocking action that occurs with stepping onto the ball of the foot. I will also have them do the same comparative movement.  They readily see the instability of rocking the foot as one is shifting the weight vs. “planting” the foot.

Students who do the basic walk for a while will not stand up when they lift the leg to take a step.  By “standing up”,  I mean that the weight bearing leg does not flex and straighten itself.  This type of flexion will result in the student bobbing up and down as they walk.  Or what might be called a kind of duck walking .  To do the walk correctly, the bend of the standing knee will not change as you lift the other leg,  whether moving forward or backward.  I have my students lightly touch a wall as they move, so lightly that the fingers gently slide as they walk.  I tell them that if they are aware enough, they will actually feel the hand move up and down if the “standing” leg is bobbing up and down as they walk.  Another technique I recommend is to put a piece of tape on a mirror at the level of one’s head as they stand with knees bent. Students   watch   the top of the head as one walks toward it.  Do not bob up and down and  keep looking forward while not watching the ground.  The top of the head should not rise above the tape as the student moves.

Another use for a wall, post, kitchen counter, etc.,   is to isolate the walking practice into a few basic walking steps.  The first advantage of this method is that one does not have to worry about their balance.   In the beginning,  students will inevitably be overly concerned with balance and not able to concentrate on the real movement itself.  With holding on to the wall or post, at least the balance problem takes care of itself so one can give full attention to the actual practice and training of movement.   In a first step, the full planting of the foot while holding the pole will make it less likely that the body lurches forward.  Additionally, the student can check their posture in either lean or sit back positions because they can take an extended pause with no concern for maintaining balance.  Is the rear end tucked in, is the neck stretched up, is there a continuous stretch from top of head to bottom of heel, etc.  ?  In this one position, one should just slowly deliberately shift the weight from front to back while pausing to do the self - check in each posture.

Another method one can use for these exercises is to do numerous continuous walking steps while sliding the hand along a wall.  This method  is slightly different from my teachers which as I iterated involves  holding  a support without moving the hand.  I teach students to practice different exercises while using both methods. The “holding” onto a support is very useful for lessons that involve the training of core movement to move the body.  Students doing this can do many repetitions where they can contract the lower abdomen or tan tien area to move the body either front  or back and shift the weight by pulling.  Eventually, one learns to feel the contractions of the abdomen engage the lower back, buttocks, legs and feet, etc.   I tell students who struggle with feeling the contractions engage with other muscle groups to simply “pull” with the legs. Or as Mike Fittipaldi who is also a teacher put it, to “pull with the knee”.  That is the way that I started out as I gradually began to learn not only to contract the abdominal muscles but also to learn where they contract, how it felt and how to engage the other parts of the body.

One other method I use for “core contraction” training is to have students simply sit in a straight back chair with one foot slightly in front of the other.  I then tell the student to contract the muscles of the lower abdomen while leaning the upper body slightly forward.  From the “lean” position, I then tell students to contact the lower abdomen while pulling the body back to a straight and perpendicular sitting position.  Like the “holding” onto a support while one stands, this sitting in a chair method can generate many, many repetitions to train such core contractions and body movement.  The student thinks and feels what sensations are happening and to look for such things as engagement with the feet to coincide with the pulling action. One can also gradually learn to detect engaged muscle groups such as the back, buttocks, etc. 

Another component or method for training the walking is to hold the support, take a couple of steps either forward or backward and pause at each juncture.  Of particular significance at each “pause” is to check head stretched up, and a stretch from top of head to bottom of heel.  However, an additional check is made on how well the rear end is “tucked” in with both the forward lean and sit back postures.  For the forward lean one still has to try and tuck in the buttocks.  For the sit back posture, one also has to tuck in the buttocks.  In the lean of course, one will not fully tuck under the buttocks as much as one can when sitting back.  I frequently point out to beginners how important the tuck is.  To illustrate this I have them move to touching a wall with the backs of their body.  With their legs straight and not bent at all they see they can run their hand through the curve in their lower back between the back and wall.  Then I have them bend the knees and tuck in the behind while feeling the same area of the lower back.  With their back to the walls I can also have them practice the “one step” method of shifting the body back and forth numerous times.  When they pull back, I urge them to see which part of the back will touch the wall first.  If the shoulders or even the head touches the wall first, the obvious correction is to tuck in the buttocks fully.  The lower back near the sacrum should be touching the wall with no other portion of the back in contact. These types of additional practices besides breaking down the various components of walking thus enable students to practice the most difficult portions of the walking.
