Neural tension test and mobilization Introduction neural mobilization is a treatment technique used in relation to pathologies of the nervous system. Physiology Nervous system adapts to mechanical load by Elongation Sliding Cross sectional changes Angulation and Compression Failure of these dynamic protective mechanism leads to altered neuro dynamica Neural glides restore the dynamic balance between neural tissue movement and surrounding mechanical interface This reduces intrinsic pressure on neural tissue Thus promoting optimum physiological function Tension is applied-----reduses cross sectional area-----increase in intraneural pressure-----reduses blood supply to nerves-----affects axonal transport system Neurodynamics ---david butler Use of body movement to produce mechanical effects on the peripheral nervous system with central influence. Benefits of neural mobilization Circulation and nutrition occur optimally through movement MS tissue changes dimension and exert mechanical forces on neural structures Management of injured neural tissues should ensure that MS structures operate optimally Minimize forces on adjacent neural structures Movement of the nerve bed Should elongate and shorten the nerve Increase nerve tension and intraneural pressure Facilitate venous return Disperse edema Reduce pressure inside the perineurium Should limit fibroblastic activity Which may minimize scar formation Physical loading(tension or compression)of the nervous system can be produced by adjusting joint postion Assessment Determine if the test is positive Determine structure at fault Determine if it is irritable or nonirritable Apply appropriate grades of mobilization Patient education Document continually re-evaluate Definition Neural tension test is an established component of neruo-orthopaedic examination in which the tension in the nerves is increased thus reproducing the signs and symptoms proving neural involvement.
