Clinical Trial Summary

The median nerve is a mixed nerve with motor and sensory functions in the upper extremity. It is observed that the median nerve slides longitudinally during upper extremity movements. However, in entrapment neuropathies (eg, Carpal Tunnel Syndrome), longitudinal displacement of the nerve is partially limited. In addition, the presence of adhesion, fibrosis, and possible scar tissue may cause difficulties for peripheral nerve adaptation in certain positions and movements. This, in turn, can result in the limitation of nerve trunk movements with respect to the surrounding tissues and a reduction in the normal shift of nerve fibers and fascicles relative to each other and to the connective tissues. Any pathology that reduces the normal stretch and slip of the medial nerve produces abnormal tension during extremity movement and the pressure on the nerve increases. This may cause symptoms such as paresthesia, weakness, and pain in the hand. With neuromobilization exercises, the tension and pressure on the median nerve are reduced and the nerve is prevented from being compressed in the carpal tunnel.

Neuromobilization is part of manual therapy and has been reported to be an effective practice for some conditions, including low back pain and carpal tunnel syndrome. The inclusion of neuromobilization in the treatment of patients with carpal tunnel syndrome, cervicobrachial pain, and lateral epicondylitis, in particular, has been associated with a reduction in the degree of pain and disability. Recently, neuromobilization techniques have started to be used in the treatment of nerve compression. These techniques consist of a series of therapeutic active and passive movements aimed at restoring the normal mechanical properties of the nerve during limb movements.

When the literature is examined, there are not many studies that objectively reveal the effects of neuromobilization techniques on nerve elasticity. Shear Wave Elastography is a method that quantitatively reveals the elasticity of tissues by measuring the speed of shear waves formed in the tissues through non-invasive high-frequency ultrasound waves. In recent studies, Shear Wave Elastography has shown promising results in demonstrating the elasticity of peripheral nerves.

Intervention

Other:
• Neuro mobilization
For median nerve stretching, the participants' dominant forearms will be in the supination position while the shoulder will be depressed and abducted 90 degrees. In this position, while the participant's head is lateral flexed to the opposite side, the wrist and finger will be extended and median nerve stretching will be performed. After staying in this position for 30 seconds, the participants will relax by placing the wrist and head in the neutral position. Thus, a set for median nerve stretching will be completed. For median nerve gliding, the dominant side of the individuals' forearms will be in supination, while the shoulder will be placed in a depression and 90 degree abduction position. In this position, the participant will flex the wrist and fingers while lateral flexing the head to the opposite side, and extend the wrist and fingers while the head is lateral flexed to the same side.
• Sham neuro mobilization
Sham neuromobilization will be applied to the nondominant side upper extremities of the participants.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Median Nerve Tension Test	The test is performed with the participant in supine position with shoulder depression and 90 degrees abduction and external rotation, elbow 90 degrees flexion, forearm in full supination, and wrist and fingers in full extension. Maintaining this position, the elbow is passively extended to test the tension of the median nerve. The test is stopped at the point where the patient feels pain and tension, and the angle formed at the elbow will be measured with a universal goniometer and recorded. The measurement will be repeated 3 times and the average value will be recorded.	1 week
Primary	Shear Wave Ultrasound Elastography	Nerve elasticity will be measured by measuring the speed of shear waves formed in the median nerve by means of high frequency ultrasound waves.	1 week
Secondary	Range of Motion	Wrist flexion and extension will be measured bilaterally with a universal goniometer.	1 week
Secondary	Finger Grip Strength	Finger grip strength will be measured bilaterally with a pinchmeter.	1 week
