EARLY EXTENSION

The following limitations are usually at the origin of this swing characteristic.

When there is a Thorax Spine Extension/Rotation Mobility Dysfunction, it is hard for the player to rotate their shoulders, many will compensate this limitation by standing up during the swing.

Positive Tests: “Torso Rotation”, Lumbar Locked Extension/Rotation.

​

Reduced thorax or pelvic mobility and stabilisation, will cause the player to extend the lumbar area instead of extending/rotating the thorax.

Positive Tests: “Pelvic Rotation”, “Torso Rotation”, Lumbar Locked Extension/Rotation, Extension Rolling Patterns.

​

A core stability and/or Motor Control Dysfunction and a Lumbar Spine Flexion Stability and Motor Control Dysfunction will also cause the player to extend the lumbar area instead of extending/rotating the thorax.

Positive Tests: “Bridge w/ Leg Extension”, “Pelvic Tilt”, Passive Lumbar Locked Extension/Rotation, Half Kneeling Narrow Base, Prone Rocking, Flexion Rolling Patterns.

​

A Lead Shoulder Flexion Mobility Dysfunction can make it difficult for the player to lift their arms, in response, they will tend to stand up.

Positive Tests: "Lat", Shoulder Flexion Test.

Generalised tightness and asymmetry in the lower body can be caused by poor posture, sedentary lifestyle, prolonged asymmetrical activity, muscular imbalance, osteoarticular, fascial and musculoskeletal restrictions/adhesions in the hip and lower body and reduced ankle mobility.
Positive "Overhead Deep Squat" Test.

Any Hip Rotation Mobility Dysfunction can prevent the player from rotating their lower body in the swing, causing them to Early extend instead. This can be caused by osteoarticular, fascial and musculoskeletal restrictions/adhesions in hip, lower body, muscular imbalance, and reduced mobility and stability of ankle and foot.

Positive Tests: “Lower Quarter Rotation”, Seated and Prone Hip Rotation.
