Introduction to Golf Rehabilitation and Performance: 90 Percent Mental, 90 Percent Physical: Summary 37
Shot Physics • Ball behavior will depend on face angle relative to swing path relative to the target • Swing considerations: ○ Path : Direction the club is being moved ○ Face : Angle of the face when club hits the ball ○ Target : Line that is chosen between where golfer is and where they want to hit ball RELEVANT ANATOMY
Shoulder • Regions/components : ○ GH joint ○ Humerus ○ Scapula (glenoid)
• Actions :
○ Flexion ○ Extension ○ Abduction ○ Adduction
○ Internal rotation (IR) ○ External rotation (ER) ○ Horizontal abduction ○ Horizontal adduction
Foot/Ankle • Regions:
○ Forefoot ○ Midfoot ○ Rearfoot ○ Ankle
Cervical Spine • Actions : ○ Flexion ○ Extension
• Actions:
○ Tibial rotation ○ Dorsiflexion ○ Plantarflexion
○ Sidebend (Left/Right) ○ Rotation (Left/Right)
○ Inversion ○ Eversion
MECHANICS • Orientation of a joint : Refers to movement of the joint in space • Motion of a joint : Refers to movement of the bones relative to one another: ○ Real motion: Bone position and bone movement ○ Relative motion: Joint position and joint movement Golf Swing Mechanics • Backswing :
○ Internal rotation (IR) ○ External rotation (ER) ○ Supination/pronation
Hip • Regions : ○ Femoroacetabular joint: Femur + Innominate (acetabulum) • Actions :
○ Internal rotation (IR) ○ External rotation (ER)
○ Right subtalar eversion ○ Left subtalar inversion ○ Right hip IR/adduction/extension ○ Left hip ER/abduction/flexion ○ Right thoracic rotation
○ Adduction ○ Abduction ○ Flexion ○ Extension
○ Right posterior rib expansion ○ Left anterior rib expansion ○ Right shoulder ER/horizontal abduction ○ Left shoulder IR/adduction ○ Cervical rotation left • Downswing/follow-through : ○ Left hip IR/adduction/extension ○ Right hip ER/abduction/flexion ○ Left thoracic rotation ○ Left posterior rib expansion ○ Right anterior rib expansion ○ Left shoulder ER/horizontal abduction ○ Right shoulder IR/adduction ○ Cervical rotation right ○ Left subtalar eversion ○ Right subtalar inversion
Thorax • Regions/components : ○ Thoracic spine ○ Ribs ○ Sternum • Thoracic spine actions : ○ Flexion ○ Extension
○ Side bend (left/right) ○ Rotation (left/right)
• Rib actions :
○ Bucket handle—lower ribs ○ Pump handle—upper ribs
