Trigger Point Signs and Symptoms: Symptomatology is similar to that of a Thoracic outlet syndrome, with the arm and forearm pain excluding the elbow and wrist being a cardinal indicator. Due to possible entrapment of the subclavian artery it is possible to have a positive Adsons Test, especially when the shoulders are elevated (Modified Adsons Maneuver).

Trigger Point Activating and Perpetuating Factors: Persistent shoulder elevation e.g. sitting with arms too high in a chair, leaning on one elbow at a desk, or sleeping on ones side with their arm elevated above their head.

Differential Diagnosis: Brachial plexus entrapment, Thoracic Outlet Syndrome (Scalenus anticus, Costoclavicular, or Cervical rib syndromes), (Segmental, Subluxation, Somatic dysfunction) C5 or C6 radiculopathy, Angina Pectoris, Myocardial Infarction, Frozen Shoulder (Adhesive Capsulitis), Subclavian artery entrapment, Rotator Cuff Injury, Dislocated Clavicle, Fractured clavicle, Separated Shoulder, Charcotís Arthropathy, Fibromyalgia, Systemic lupus erythematosus, Osteoarthritis, Osteoporosis, Stinger or Burner, Eosinophilic fasciitis, Tetanus, Systemic infections or inflammation, Nutritional inadequacy, Metabolic imbalance, Toxicity, Side effects of medication.
