How Lower Extremity Injuries Impact Ground Utilization and Swing Mechanics
Thu Mar 8, 2018 by Adam Halseth
The world of golf is becoming much more aware of the importance of utilizing the ground to maximize efficiency and power in a golf swing. Today’s game has so much emphasis on maximizing distance that knowing how to create speed and power is critically important to being a competitive golfer, and this begins with footwork and ground interaction. A recent article by BodiTrak highlights how Rory McIlroy utilizes the ground to generate power. Being a golf medical provider, I have seen many trends as to how body limitations and injuries can impact a golfers interaction with the ground.
When assessing a player's interaction with the ground, I assess the pressure in each foot, the timing and velocity of pressure shifts, and the timing and amplitude of ground reaction forces using BodiTrak pressure mats. Certain trends can be observed with each of these variables as they relate to physical limitations and previous injuries. In the following paragraphs I will break down how these variables may be impacted by lower extremity injuries and body limitations.
This can affect their ability to push off the trail leg and change the timing and the speed of which they transition to lead side. When golfers are more tentative with their transfer to the lead side, their GRF tends to be highest at a later point in the downswing (closer to impact. Generally, a trend we see in elite ball-strikers is that they have pressure on their lead side earlier in the downswing, most notably at shaft vertical on the downswing. This is an important characteristic of golfers who are most effective at using the ground to generate clubhead speed.
Dorsiflexion limitations are commonly found in those with achilles tendinopathies, previous ankle sprains and a multitude of other injuries. I usually will notice DF mobility limitations when assessing the overhead deep squat as described by the SFMA. TPI has found a strong correlation with limitations in the overhead deep squat and early extending in the downswing. Frequently, overhead squat limitations can be rooted in dorsiflexion mobility impairments. This causes altered movement patterns in a squat that tend to replicate in the golf swing resulting in early extension. When assessing pressure changes in early extension, you will see a pressure trace moving anterior with pressure more on the toes throughout the downsing and at impact. The relationship between ankle and early extension is discussed by Dr. Greg Rose in this article.
The knees are a more stable joint, compared to the mobile ankle and hip joints. However, previous knee injuries will tend to negatively impact quad strength and stability in the knee. This is critically important on the lead side. Golfers rely on the ability to push off on the lead leg to effectively transfer energy through the body to the clubhead and maximize speed. The ability to do this can be impacted when quad strength deficits, decreased neuromuscular control, and poor loading strategies are present. This will occur following injuries such as past ACL tears, meniscus tears, and chronic issues such as osteoarthritis. That weakness and instability in the knee can affect the timing of the pressure shift and limit GRF as they are not comfortable transferring weight quickly or forcefully into the lead leg, resulting in max GRF at impact compared to early in the downswing, again decreasing potential to maximize clubhead speed.
Any decrease in ability to rotate the hips in either side will significantly reduce a golfer's ability to effectively load that side. Arthritic changes in the hip joint, labral pathologies, CAM and PINCER lesions, among others pathologies will all affect the ability to rotate. When golfers can not rotate well around their hip, they may demonstrate various swing characteristics such as a sway and slide, reverse spine angle, early extension, among others. When hip pathologies are present or a history of hip injuries/surgeries (i.e. hip replacement) they tend to have glute strength reductions as well.
Below is a general example of a progression I may use for golfers such as him that struggle to efficiently transfer weight and/or appropriately push off their lead side with focus on controlling the movement. These are intended to improve movement patterns after they have the necessary mobility and stability prerequisites to safely perform without compensatory actions. Doing this drill will teach the golfer to correctly utilize the ground and transfer weight quickly and efficiently during the golf swing. Scroll to the right to see all four videos:

Adam, I'm a resent total knee replacement patient. I've had a successful surgery and am now trying to get back to golf. Since I'm a writer, I've embarked on a project about Returning to Golf After Total Knee Replacement. I've been interviewing my surgeon here in New York as well as the Physical Therapists I've worked with, two of whom have recently been certified by Titleist. Do you know whether TPI has started doing specific things to accommodate golfers that have undergone joint replacement surgery (shoulder, hip or knee)? I would love to talk to someone at TPI who might know more about this subject. Best regards, David Smith 516-458-8240,

Ian. Please contact me, I also completed the Medical Level 3 certification and own and operate StrongSwing in Naples, FL. I use KAATSU blood flow moderation training with my golfers and it's great at helping recover from injuries and/or surgery. I can be reached on my cell 203-422-6665 or firstname.lastname@example.org

Sir This is interesting but not applicable for me . i have a replaced right hip 2008, left ankle 2014,both knees 2016. I have now a full plus range of motion in my left ankle ( more than right ) full right hip , both knees full extension 140 degrees flexion. I have regained full leg and gluteal strength. My problem is still decreased proprioception in both legs ans delayed weight transfer and push up on left leg. some exercises you show are not really possible without risking damaging my artificial joints. Just to add to the problem I am 79 and play or on the practice ground everyday here in Naples FL
