Brief Summary

The aim of the present study is to value the effectiveness of an Eye-Cervical Re-education Program (ECRP) to decrease pain and increase mobility in the cervical area compared to a Combined Physiotherapy Protocol (CPP) in patients with chronic neck pain symptoms.

Detailed Description

Background:

In Physiotherapy there is a growing interest of authors to clarify the relationship between the visual system and the neck. Aspects such as deficiencies in eye movement during cervical rotation are common disorders in patients who have suffered whiplash trauma or have dizzy syndromes. On the other hand, deep muscle disorders of the neck are related to the decrease in cervical-ocular reflex. Furthermore, some disorders in eye movements in patients with idiopathic neck pain have been identified.

Consequently, a pragmatic approach to multimodal intervention has been recommended to address changes in sensorimotor control at the cervical level. For this purpose, head-neck sensitization exercises (joint position sense training with head relocation), oculo-motor exercises (ie, eye stability, eye-neck coordination) or balance training have been proposed. These programs lead to a sensorimotor control, reducing pain and disability in the neck. However, it is not known if this approach to treatment is a significant improvement when compared to the implementation of other physiotherapy procedures, so it is unknown if the application of training oculocervical proprioception is more advisable than other modalities of physiotherapy treatment for the improvement of CNP symptoms.

Material and method:

This research is an analytical, longitudinal, prospective, experimental, evaluator blinded study. It is controlled with two parallel groups, randomized clinical trial.

The sample consisted of patients recruited in a Physiotherapy consultation in Cadiz (Spain). These assessments were made before and after the start of program and to the end of intervention (8 months).

Patients were randomized to control or experimental group. All patients are given a Combined Physiotherapy Protocol, no apply an Eye-Cervical Re-education Program in subjects in the first group and performing an Eye-Cervical Re-education Program in the second. This program was carried out by the physiotherapist. Subjects received a total of ten sessions on alternate days.

Arm && Interventions

Group	Intervention	Description
Experimental Group	EYE-CERVICAL RE-EDUCATION PROGRAM	All patients are given a Combined Physiotherapy Protocol (CPP) consisting of: Thermotherapy (70 w continuous microwave for 10 minutes), therapeutic massage (surface rubbing for 5 minutes, 10 minutes of compression and kneading massage and 2 minutes of final surface friction), application of analgesic currents (TENS, by self-adhesive silicone electrodes 4x4 cm, symmetrical biphasic rectangular current, 200 µs width pulse, a frequency of 1 Hz for 10 minutes. The patient should notice a slight vibration, without it being painful). The ECRP developed by Revel et al.(Revel et al., 1994) was also applied to patients in the experimental group. EYE-CERVICAL RE-EDUCATION PROGRAM (ECRP) This includes a total of 10 exercises that has proprioceptive reprogramming in the cervical area
Control Group	Combined Physiotherapy Protocol	All patients are given a Combined Physiotherapy Protocol (CPP) consisting of: Thermotherapy (70 w continuous microwave for 10 minutes), therapeutic massage (surface rubbing for 5 minutes, 10 minutes of compression and kneading massage and 2 minutes of final surface friction), application of analgesic currents (TENS, by self-adhesive silicone electrodes 4x4 cm, symmetrical biphasic rectangular current, 200 µs width pulse, a frequency of 1 Hz for 10 minutes. The patient should notice a slight vibration, without it being painful).
