A mechanical diagnosis and treatment (MDT) approach for a patient with discogenic low back pain and a relevant lateral component: a case report

摘要

Patients with a lateral lumbar shift are often managed with a frontal plane, manual correction first described by McKenzie. However, there is a subset of patients that require a frontal plane correction who do not demonstrate a lateral shift. Both of these patient groups have what is termed a relevant lateral component (RLC). The subset of patients who have an RLC, without a shift, has received very little attention in the literature to date. This case report describes a patient with no shift who had a remarkable disc extrusion identified by magnetic resonance imaging (MRI). The patient responded nicely to a combination of frontal and transverse plane loading strategies in six treatments using the mechanical diagnosis and treatment (MDT) evaluation and treatment system. The case report is unique in the literature in that it describes a patient with no apparent frontal plane, lumbar deformity that had documented evidence of a large disc extrusion and who responded to a variation of McKenzie’s flexion–rotation mobilization. The centralization phenomenon was demonstrated immediately when a non-weight bearing, multiplanar, loading strategy was administered.
