Arm (Biceps, Triceps, and Wrist Extensors) Vibration Release

Best Body Position:

• Supine for biceps brachii and wrist extensors
• Prone for triceps brachii
• Side-lying for deltoids

Bony Areas: (Block with a thumb or finger when approaching these areas)

• Olecranon process of the ulna
• Lateral humeral condyles

Muscles

• Middle deltoid is a superficial muscle, that creates a "cap" over the glenohumeral joint, coursing from the acromion shelf to the deltoid tubercle.
• Biceps brachii are superficial muscles that course from underneath the anterior deltoid to the cubital fossa of the anterior elbow.
• Triceps brachii are superficial muscles that course from underneath the posterior deltoid to the olecranon process
  • Common Trigger Point: Middle of the muscle belly, although trigger points in these humeral muscles are fairly rare.
• Wrist Extensor Muscles are a group of muscles that course from the lateral condyle of the humerus, into long tendons that begin at about half the length of the forearm, and extend across the joints of the wrist and fingers.
  • Common trigger points: Middle of the muscle bellies; however, the muscle bellies are relatively short, only extending about half the length of the forearm. Most trigger points occur 3 - 5 centimeters distal the lateral condyle of the humerus.
