Trigger Point Signs and Symptoms: There is an expressed weakness in grip strength especially when the hand is either in flexion or extension. The pain is initially noted at the epicondyle thus making it easy to misdiagnose as epicondylitis “tennis elbow” or tenosynovitis, the pain is exacerbated with forceful supination or pronation of the hand. If the cause of pain is triggers in the brachioradialis, they will be relatively unresponsive to anti-inflammatory medication. If the primary cause is inflammation, there should be a favorable response to rest, ice and anti-inflammatory medications.

Trigger Point Activating and Perpetuating Factors: Repetitive forceful hand gripping, e.g. gardening, using hammers, writing for long periods, sewing by hand or knitting.

Differential Diagnosis: Epicondylitis, (Segmental, Subluxation, Somatic dysfunction) C5 or C6 radiculopathy, Carpal tunnel syndrome, Tenosynovitis (De Quervain’s Disease), Arthritis, Osteoarthritis, Neurogenic Arthropathy (Charcot’s Joint), Sprain/Strain of the elbow wrist or thumb, Bone fracture, Bone cancer, Ganglion Cyst, Thoracic Outlet Syndrome, Systemic infections or inflammation, Nutritional inadequacy, Metabolic imbalance, Toxicity, Side effects of medication.
