It was through this experience that I was able to observe a number of common trends with respect to their pain presentation, joint dysfunction, range of motion, and the side in which these golfers swing their clubs. To me this was regional interdependence at its finest.
For those not familiar with the term, regional interdependence is the concept that dysfunction (either painful or silent) in areas distant to the patient's primary (main) complaint may be contributing to, or associated with the primary complaint. There are many examples of this interplay between different body parts. Neck pain may stem from issues at the shoulder or mid-back or vice versa, knee pain may arise from issues at the ankle or hip, etc.
Whether you golf or not, I'm sure you can appreciate the amount of rotation that is needed when swinging a golf club. An issue some golfers appeared to have had last week was a limitation (usually non-painful) in their ability to turn their lead leg inwards. After contact is made with the ball and they're following through with the club, there should be sufficient internal rotation of the lead leg in conjunction with rotation through the thoracic spine (mid-back). If this internal rotation is lacking at the hip, you will inadvertently find that your body "makes up" for this limitation by causing rotation or other coupled movements at a different area(s) of the body. Put another way, with any movement, your body will take the path of least resistance. If your hip is providing any resistance to your swing, you may compensate by putting more force through areas such as the transitional point between the mid- and low-back, you may extend you low back excessively, etc.
When considering the concept of regional interdependence, it may explain why foam rolling or rubbing analgesic creams over a painful area may only provide temporary relief. This is not to say these forms of self-care do not have a place, I'm simply suggesting that addressing the painful area only will not correct the underlying issue(s).
Although most of this article was written in a golf context, regional interdependence applies to all facets of human movement. If you have longstanding aches and pains that you've been unable to self-manage, having an assessment performed by a member of your health team that has a "movement" focus (chiro, physio, etc.) can provide invaluable information with regards to what may be contributing to your problem and what can be done to correct it.
