This month's issue of Backpacker includes a short article on how to "End Knee Pain Forever." Paul Simica, a physical therapist with much experience and himself an accomplished competetive athlete, contributed to the article.
The article focuses on simple exercises to strengthen and stabilize the muscles of the lower body - in particular the glutes, hamstrings, and soleus - an excellent strategy. The instructions are for isolated strengthening exercises - leg extensions, leg raises, and calf raises - all of which will do the job over time. What I wish to discuss here is the difference in approach between how western medicine uses exercise, and how Chinese medicine uses exercise. Bear in mind, one is not necessarily better than the other, they're just different.
We address injury and pain thorugh exercises taken from martial arts and qigong training. Essentially patients are taught to relax while moving the entire body as one unit as much as possible. This recruits all relevant muscle groups to work together synergistically. In this example, this means the goal is to stabilize the leg while performing movements through what should be a natural range of motion.
Some qigong exercises involve coordinating the breath with the movement of the body, some require you to contract one area while learning to relax another, but all require you to relax, and that is something no weightlifting routine talks about clearly. If done correctly, they give you the opportunity to re-learn at an unconscious level (actually a neuromuscular level) how to use the injured limb correctly, and reintegrate it into the whole of your body.
Let's examine a familiar exercise: knee rotations. Many people do these quickly and without thought as a warm-up before training. But if done slowly, in a relaxed manner, you can feel the challenges and benefits very clearly: knee rotations done in this way will show you which hip is tighter than the other, challenge you to stabilize the leg as a whole (especially the adductors and abductors of the upper leg), and remind you to relax the back. Challenge yourself further by keeping the feet flat on the floor, and you're on your way to balancing the strength of the muscles of the lower leg such as the soleus, calves, tibialis anterior, and peroneals, some of which are major players in meridian therapy when it comes to knee pain.
Squats, when performed slowly and with the heels on the floor, can be an even bigger challenge and also engage your core. (Please don't try any of these without proper guidance; these are just two of many exercises we use for knee pain, and they may not be right for your presentation.)
If you're having knee pain, don't wait to have it treated. Usually it's a pretty straightforward thing for acupuncturists to deal with, but it's not going to abate on its own. Most knee pain seen in the clinic is the result of imbalances of the muscles above and/or below the knee, or the ligaments and connections inside the knee. As time goes on, problems tend to get worse as our bad habits (including those when walking) become more ingrained within our mechanics. Get it treated to stop the pain and increase your reange of motion, then rehabbing it should be much easier.
