Hypoalgesic Effect of Neural Mobilization

The Cervical Lateral Glide (CLG) is a neural tissue mobilization technique capable of achieving a hypoalgesic effect during the onset of cervicobrachial pain symptoms. This happens through a series of complex physiologic interactions which are not fully understood. The CLG Physical therapy technique consists of controlled movements of the cervical and brachial plexus neural tissue. Hypoalgesic effect produced by CLG is associated to an increase in neural tissue mobility, edema, inflammation and intraneural pressure reduction, without any known side effects when applied properly, except for a momentary worsening of symptoms (the only known side effect of CLG), which is an important contrast to the wide and sometimes severe spectrum of side effects derived from drug therapy used to treat cervicobrachial pain.

It is believed that the hypoalgesic effect offered by neural tissue mobilization is a consequence of descending nervous system pain modulation activity and an improvement in the distinct biomechanical properties of the involved neural tissue.Despite the increase in scientific interest in evidence based options to treat pain and neural tissue mobilization techniques there is a current lack of enough controlled double blind clinical trials that measure the effectiveness of neural tissue mobilization techniques such as the CLG and its specific effect over cervicobrachial pain. For this reason the present investigation consisted in the application of a treatment protocol based on CLG neural tissue mobilization in a controlled double blind clinical trial with the aim to assess its clinical effectiveness in treating pain symptoms
