Test Objective for 90/90 Test
This test is designed to highlight any limitations in mobility of the gleno-humeral joint and/or stability of the scapulo-thoracic junction. More specifically, the 90/90 Test measures the player’s range of external rotation in the shoulder and their ability to maintain scapular stability in a golf posture. We look at the amount of external rotation in each shoulder from a standing position and then compare that range to how the shoulder rotates in their golf posture. Many golfers will lose range of motion in their golf posture due to a lack of scapular stability. If the shoulder blade elevates or flares due to muscular imbalances or poor posture in their golf stance, it will change the orientation of the glenoid fossa (shoulder joint). This in turn, will greatly reduce the amount of external rotation in their shoulder joint. |
Test Objective for the Lat Test
The Lat Test evaluates shoulder flexion which includes the flexibility of the latissimus dorsi muscle group, shoulder joint restrictions and scapular motion limitations. The lat muscle spans the entire back and inserts onto the arm. Tightness in the lat can lead to loss of spinal posture anytime the arms are elevated, such as during the backswing. Also, the lat muscle can limit the ability of the player to rotate their shoulders on the backswing or the follow-through. Common swing faults caused by lack of lat mobility are, Loss of Posture, Reverse Spine Angle, Limited Arm Heights, and Over-The-Top. The lat muscle is a powerful internal rotator and adductor of the humerus. Therefore, it is a major contributor to power in the golf swing. |
OVERHEAD DEEP SQUAT TEST:
Test Objective for Overhead Deep Squat Test: The Overhead Deep Squat Test is one of the most informative tests you can perform on a golfer. The deep squat portion of this test is used to assess bilateral, symmetrical, mobility of the hips, knees, and ankles. When you combine the dowel held overhead this test also assesses bilateral, symmetrical mobility of the shoulders as well as the thoracic spine. Therefore, the ability to perform this test requires closed-kinetic chain dorsi-flexion of the ankles, flexion of the knees and hips, extension of the thoracic spine, as well as flexion and abduction of the shoulders. |
PELVIC TILT TEST:
Test Objective for the Pelvic Tilt Test: The Pelvic Tilt Test is a great test for overall mobility of the hips in the lumbar spine and their ability to control the position of their pelvic posture. The ability to move and control the position of the pelvis is critical for optimal power transfer from the lower body to the upper body during the golf swing. |
Test Objective for the Bridge w/ Leg Extension Test
The Bridge w/ Leg Extension Test is a great test for stability in the pelvis/lumbar spine/ core, especially the gluteal muscles. Glutes are the kings when it comes to stability and generating power from the ground up. This test will highlight any inhibition or weakness in the glute max due to over-recruitment of synergistic muscles, such as the hamstrings and lower back. How to Perform the Bridge w/ Leg Extension Test Start with the golfer supine, knees bent, feet flat, knees and feet together and arms extended out over the chest. Have them lift the pelvis up off the ground. Instruct them to keep the belt line parallel to the floor and try to extend the right leg from the knee. Have them hold this position for ten seconds. It indicates an instability in the glute on the left side if the pelvis on the right side drops or the left leg shakes. It indicates inhibition of the glute and recruitment of the synergistic muscles if the left hamstring or lower back starts to cramp. Repeat the test on the other side. |
The Single Leg Balance Test
Test Objective for the Single Leg Balance Test The Single Leg Balance Test measures the golfer’s overall balance. It highlights any ankle mobility or proprioceptive imbalances from left to right as well as overall stability in the core. How to Perform the Single Leg Balance Test Have the player stand tall with their arms down by their sides, but not touching their sides, and elevate one leg until the thigh is parallel with the ground. Once stable, have them close their eyes and see how long they can maintain balance. Any re-positioning of the foot is considered a loss of balance. Record and repeat on the other side. More than 25 seconds is considered normal so stop the test after 25 seconds. |
