A recent study investigated the proportion of patients that present with isolated extremity pain who have a spinal source of symptoms, and evaluated it’s response to spinal intervention. Using the McKenzie system of Mechanical Diagnosis and Treatment (MDT), they found over 40% responded favorably.
The authors referred to this condition Extremity Pain of Spinal Source (EXPOSS). Patients whose pain is due to a MDT classified Derangement experienced the most rapid changes in their symptoms in response to different end range spinal movements, especially a directional preference, and loading strategies. The arm/forearm were found as the most prevalent EXPOSS at over 80% occurrence, followed by the hip and thigh extremity pain with over 70% relieved from spinal treatment.
