About

The main objective:

To determine changes in physiological and structural properties of upper limb muscles with spasticity in patients with acquired brain injury after applying neural mobilization improving their functional performance, their participation in society and quality of life.

Hypothesis:

Peripheral nerve mobilizations performed with neurodynamic techniques in upper limb in patients with acquired brain injury, generate changes at structural and physiological level, favoring the performance of daily life activities and improving the quality of life.

Full description

Randomized clinical trial with blinding of the subject, the evaluator and the person analyzing the data.

In the experimental group will be performed neural mobilitazion technique, while in the sham a technique to mimic neurodynamic.

The assessment will be made by a single evaluator.

Intervention group

Experimental group

Description:

The Upper Limb Neurodynamic Test (ULNT1) technique described by Butler will be performed on the affected limb. This technique consists of performing shoulder depression, 90º shoulder abduction, hand, wrist and forearm in a neutral position, external rotation of the shoulder and extension of the elbow. After positioning the limb in this position, wrist flexion-extension movements will be performed smoothly and rhythmically of 20 movements every minute, for 3 minutes, three times per session with 1 minute of rest between each series.

Treatment:

Other: Neurodynamic

Mimic group

Sham Comparator group

Description:

The protocol used by Beneciuk et al. Will be used. This intervention consists of imitating NM without stressing the nervous system. It will be carried out as follow: a neutral cervical position will be maintained (0º of cervical inclination), 45º of shoulder abduction without depression, 45º of external rotation of the shoulder combined with 45º of elbow flexion with the forearm in pronation. Afterwards, 10 wrist flexion-extension movements will be performed at a rate of 6 seconds per cycle (3 seconds of flexion and 3 seconds of extension). The resistance that you will feel will stabilize when you change motion. Once the 10 cycles of movements have been carried out, a wrist flexion will be maintained for 10 seconds.

Other: Mimic group
