Paul Chek, in his excellent book, The Biomechanics of Golf, writes: "Amateur golfers achieve approximately 90 percent of their peak muscular effort when driving a golf ball. This is the same intensity as picking up a weight that can only be lifted four times before total fatigue." And that's just for one swing! Golfers take hundreds of swings when they play or practice golf.
Golfers have a high incidence of injury. It has been reported that nearly 50 percent of golfers will eventually suffer a golf-related injury. The injuries are of the repetitive strain variety. Your patients swing their golf clubs at speeds of 90 to 115 miles per hour. When they swing off-balance, there is undue and often violent strain on the muscles, tendons, ligaments and joints of the body.
So how do you, as the treating physician, identify issues of balance in the golf swing? It begins with understanding the "plane line." This is a line on the ground that starts just behind the golf ball and runs 10 feet behind the ball. There are four key points to identify and diagnose when your patient move their body and swings the club relative to the plane.
To swing on-balance means that as you generate kinetic energy during your backswing, you will release the stored energy down the plane line through the ball and directly toward your intended target.
An off-balance golf swing implies that your patient has lost the necessary positional relationship and alignment to the plane line.
During the downswing, the stored kinetic energy is not released toward the intended target. Your patient's body will react by reflex once it realizes it's out of position. Watch compassionately as your patients flip their hands and overreach, push and pull with the arms, then lunge at the ball. They will do whatever it takes to "get that darn ball to behave!" However, the muscles, tendons, ligaments and joints eventually become strained from the abuse.
Correction Protocol: Your patient must undergo repetitive, yet objective, neuromuscular re-education. The goal is to retrain the body to release the stored kinetic energy of the backswing safely and efficiently down the plane line, through the ball and toward the intended target. This will minimize, and in many cases, eliminate the unwanted strain on the muscles, tendons, ligaments and joints of the injured golfer.
Have your patient tape the plane line on the floor, and rehearse his or her backswing and downswing with the left arm parallel to the plane line between 6-9 o'clock on an imaginary clock face. (They do not need to hit balls to rehearse. In fact, it's better that they do not hit balls while re-educating the neuromuscular pathways and motor memory). They will need a device known as a "swing trainer" to be able to practice tracing the incline plane of the club shaft relative to the plane line. This should be repeated 30-50 times daily for three weeks. After three weeks of perfect rehearsal, your patient will have a new golf swing.
If we can see the root cause of the repetitive strain syndrome, it is our responsibility to identify the problem to the patient and offer a corrective solution.
