About

The purpose of this study was to evaluate the immediate mechanical hypoalgesic effect of neural mobilization in asymptomatic subjects. We also compared neural gliding versus neural stretching to see which produced greater hypoalgesic effects in asymptomatic subjects.

Full description

Asymptomatic subjects will be randomly allocated into three groups: the neural glide group; the neural stretch group; and the placebo group. Each subject will receive one treatment session. Outcome measures included bilateral pressure pain threshold measured at the trigeminal, cervical, and tibialis anterior points, which will assess pre-treatment and immediately post-treatment by a blinded assessor. Three-way repeated measures analysis of variance was used to evaluate changes in pressure pain threshold, with group (experimental or control) as the between-subjects variable and time (pre-, post-treatment) or side (dominant, nondominant) as the within-subjects variable.

Inclusion criteria

  • Asymptomatic subjects who met the inclusion criterion of being between 18 and 30 years old.

Exclusion criteria

  • rheumatologic diseases or any type of cancer, cervical surgery in the past, whiplash trauma and undergoing any type of treatment like physical therapy, manual therapy, osteopathy, chiropraxis, acupuncture during the last three months. All patients recruited for the study complained of pain localized in the neck and/or head region. Initial screening was accomplished by telephone and eligible persons attended a evaluation appointment.
  • development of systemic or degenerative diseases
  • subjects with symptoms of depression according Beck's questionnaire
  • pain in any area between the lower back and head in the last 9 months
  • traumatic event in the past 12 months
  • history of neck or face pain in the last 6 months

Neural glide
Experimental group
Description:
This technique involves two movements, initial and final. It consists of going from one to the other constantly. The therapist took the subject's head by putting his hands on the suboccipital and front region. In the initial movement, the therapist perform craniocervical flexion in the subject, while he helped with his right elbow to rectify the dorsal spine of the subject; at the same time, the subject perform dorsiflexion of the right ankle. In the final movement, the subject must increase thoracic kyphosis at the same time as perform plantarflexion in the right ankle; also, the therapist performed craniocervical extension in the subject. The session lasted 7 minutes.
Treatment:
Other: Neural stretching
Placebo
Placebo Comparator group
Description:
The model of the ultrasound (ENRAF-NONIUS, P.O. Box 12080, 3004 GB Rotterdam, The Netherlands). The subject was placed in a prone position, with arms along the body and the head in the hole of the examining couch. The therapist applied a non-therapeutic dose of ultrasound for 7 minutes with no break all over the cervical area and trapezius, in circles.
Treatment:
Other: Neural stretching
Other: Neural Glide
Neural Stretching
Active Comparator group
Description:
In the start position, the subject was supine on a couch, with knees bent with the right leg above the left, and supported with the popliteal zone. Both hands were crossed over the chest. One hand was placed on the occipital, and the other hand was placed over the crossed hands of the subject . In the final position, the therapist made the subject execute a craniocervical flexion while he pushed the subject's hands against the chest, in order to increase thoracic kyphosis. At the same time, the subject had to raise the elevated leg without separating the popliteal zone in the other knee, while maintaining dorsiflexion of the ankle and a maximum knee extension. The session lasted 7 minutes.
Treatment:
Other: Neural Glide
