Clinical Trial Summary

This study will compare changes in longitudinal median nerve excursion when neck flexion and ipsilateral rotation are added to the standard Median neurodynamic test1 (MNT1) position in patients with carpal tunnel syndrome (CTS) and normal controls.

Description:

Median nerve excursion will be assessed by ultrasonography during three positions: standard MNT1, neck flexion with MNT1, and ipsilateral rotation combined with MNT1. Both arms will be tested.

Arm will be held in abduction to 90° - 110° and external rotation to 90°, forearm supination, elbow extension and wrist and fingers extension using a custom made splint.

The standard MNT1 includes neck contralateral side flexion. Then, the researcher will move the neck passively into rotation and flexion. Passive range limit will be determined prior to testing using a goniometer and passive end feel. Movement order will be randomized using an excel random function.

Every position will be tested three times. A single researcher will do all movements passively. Nerve excursion will be measured in real time by the same ultrasonographer who is blinded to patients grouping.

Exclusion Criteria:

• Severe CTS.

• Symptoms referred to the neck.

• Limited neck flexion, rotation, and side bending ranges (>10%).

Intervention

Procedure:
• MNT1
Participants will in supine. Arm will be position in standard MNT1. Shoulder, elbow, wrist and fingers will be maintained in the required position using a costumed splint throughout all testing. All movements will be limited to the range where pain or other symptoms are not provoked. Passive neck flexion and rotation will be added to MNT1 and will be applied as tensioning movements at level 3. All movements will be repeated three times and an average will be calculated. Myrin goniometer will be used to assess neck flexion and rotation. The movements order will be randomized using excel random generation function. Movements will be done by a single trained therapist. The end position will be held up to 10 seconds until median nerve excursion is recorded by US. For US capturing, the transducer will be positioned perpendicularly and aligned longitudinally with the median nerve at the wrist. Assessor will be blinded to participants grouping.
