Study Overview
Brief Summary
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.
Detailed 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.

- •traumatic event in the past 12 months
- •history of neck or face pain in the last 6 months
Outcomes
Primary Outcomes
Pressure pain threshold assessment
Time Frame: 5 minutes
The pressure pain threshold (PPT) is defined as the amount of pressure at which the sense of pressure first changes to pain. A digital algometer (FDX 25, Wagner Instruments, CT, USA) consisting of a rubber head (1 cm2) attached to a pressure gauge was used to measure PPTs. Force was measured in kilograms (kg); therefore, thresholds were expressed in kg/cm2. The protocol will use a sequence of three measurements, with an interval of 30 seconds between them. PPT will assess over bilateral masseter points 1 and 2, the temporalis muscles, the suboccipital muscle, the upper trapezius muscle (midway between C7 and the acromion), and the tibialis anterior muscle (upper third of the muscle belly) by an assessor blinded to the subject's condition.
