Effectiveness of the Neural Mobilization on Upper Limb Functionality in Patients With Acquired Brain Injury

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.

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.
