Effects of Nervous System Mobilization

Not Applicable

Completed

• Conditions: Healthy Individuals
• Interventions: Other: Neural mobilization - tension.; Other: Neural mobilization - gliding

• Registration Number: NCT03029260
• Lead Sponsor: Aveiro University

Brief Summary

This study aims to compare the effect of tension neural mobilization versus sliding neural mobilization of the peroneal nerve on the heat and cold threshold, on pressure pain threshold and on flexibility both in the dominant lower limb (subjected to mobilization) and the non-dominant lower limb (not subjected to mobilization) in healthy young participants.

Detailed Description

Sixty young and healthy participants will be randomly allocated to receive tension neural mobilization (n=30) or sliding neural mobilization (n=30). Data on heat threshold, cold threshold, pressure pain threshold and lower limb flexibility will be collected before the intervention, immediately after the intervention and at least 24h after the intervention.

Arm && Interventions

Group	Intervention	Description
Neural mobilization - tension	Neural mobilization - tension.	It is anticipated that 30 participants will be in this group. They will receive tension type neural mobilization of the peroneal nerve in the dominant limb. This will consist of positioning the lower limb with inversion and plantar flexion of the ankle, extension of the knee and maximum flexion of the hip without pain. A physiotherapists will move the hip from this maximum position of flexion in direction to extension (for example if the participants reaches 80º of flexion the mobilization will be between 40º and 80º of flexion). Each participant will receive four series of 10 mobilizations with 1 minute rest between series.
Neural mobilization - sliding	Neural mobilization - gliding	It is anticipated that 30 participants will be in this group. They will receive sliding neural mobilization of the peroneal nerve in the dominant limb. Each participant will receive four series of 10 mobilizations with 1 minute rest between series of the following combination of movement: from ankle dorsiflexion, knee extension and hip extension to ankle plantarflexion, knee and hip flexion.

Primary Outcome Measures

Name	Time	Method
Range of motion of the Straight Leg Raising test	At least 24 hours after baseline measurements	The hip is raised to maximum flexion and the degree of flexion is measured with universal goniometer

Secondary Outcome Measures

Name	Time	Method
Cold threshold	At least 24 hours after baseline measurements	This is measured with a QSense instrument, which has thermode that is attached to the skin. The temperature in this thermode increases or decreases (as per the protocol being used) and the participants is holding a device to stop the temperature to increase/decrease when he/she first perceives it. The temperature perceived is the test result.
Heat threshold	At least 24 hours after baseline measurements	This is measured with a QSense instrument, which has thermode that is attached to the skin. The temperature in this thermode increases or decreases (as per the protocol being used) and the participants is holding a device to stop the temperature to increase/decrease when he/she first perceives it. The temperature perceived is the test result.
Pressure pain threshold	At least 24 hours after baseline measurements	This is measured using a pressure pain algometer. Pressure is made with this device against a specific body region (upper and lateral part of the dominant foot) until the participants perceives that the pressure changes to pain. The amount of pressure that the participants perceives as being painful is the test result.
