Regional musculoskeletal pain. The elbow, forearm, wrist and hand

Two main groups of soft-tissue disorders are identified: specific soft tissue syndromes and a non-specific disorder as yet not fully characterized. Specific soft tissue syndromes occur in joint, muscle or nerve and are associated with characteristic symptoms and physical signs. These include epicondylitis at the elbow, tendon disorders at the wrist and nerve entrapments such as carpal tunnel syndrome. The non-specific soft tissue syndrome is primarily described by symptoms of pain but may include muscular symptoms (such as weakness and cramp) or nerve symptoms (such as numbness, pins and needles, and burning). Agreed, validated diagnostic criteria for use in surveillance are urgently required. Biological markers are still sought; both muscle and nerve seem promising for future studies. The multifactorial aetiology of these disorders will be discussed, and guidelines to management will embrace the principles of this model. Treatments aimed at the pain in isolation are most often studied. Psychosocial and environmental influences on the presentation and persistence of pain need further evaluation.
