Posture vs. Movement

 

 

 

The optimal range of all possible movements is the middle 2/4ths of the range of motion.  

 

0 degrees = neutral position for all joint angles.    

 

Neck Flexion and Extension: 0-23 Degrees (that’s probably a lot less than you would want in order to look at the fretboard).

 

Neck Rotation: 0-40 Degrees. 

 

Neck Lateral Flexion: 0-25 degrees

 

Shoulder forward flexion: 0-90 degrees 

 

Shoulder external rotation: 0-45 degrees

 

Shoulder Abduction: 0-95 degrees

 

Shoulder External rotation: 0-45 degrees 

 

Elbow Flexion/Extension: 25-125 degrees

 

Forearm pronation: 0-60 degrees 

 

Forearm supination 0-65 degrees  

 

Wrist flexion: 0-65 degrees 

 

Wrist extension: 0-65 degrees 

 

Wrist radial deviation: 0-15 degrees 

 

Wrist ulnar deviation: 0-23 degrees 

 

Finger Metacarpal Phalangeal flexion/extension: 20-60 degrees

 

Finger Proximal inter-phalangeal flexion/extension: 25-75 degrees 

 

Finger Distal inter-phalangeal flexion/extension: 20-60 

 

Thumb basal joint Palmar Adduction/Abduction Contact/45

Radial Adduction/Abduction Contact/60

 

Thumb Interphalangeal Hyperextension/Flexion 15H/80

 

Thumb Metacarpophalangeal Hyperextension/Flexion 10/55
