Immediate Effects of Different Rates of Thoracic Mobilization on Pressure Pain Thresholds in Asymptomatic Individuals

Not Applicable

Completed

• Conditions: Spine Stiffness
• Interventions: Other: 0,5Hz mobilisation; Other: 2Hz mobilisation; Other: Placebo

• Registration Number: NCT02163590
• Lead Sponsor: Federal University of Health Science of Porto Alegre

Brief Summary

Passive mobilizations of the spine are widely used by physiotherapists in the management of neuromusculoskeletal disorders.

There is a nascent body of work of the mechanical properties of joint mobilizations. Treatment dose is characterized by the direction of force applied, magnitude of force applied, frequency of oscillation, amplitude of displacement, repetition and time. Although the choice of better treatment dose is based on patient complaints and clinical reasoning, the comprehension of the effects of different parameters of joint mobilization will improve the decision making process. The optimal dose of treatment, however, is not already known.

The primary aim of this study is to determine whether different rates of thoracic mobilization are capable to produces hypoalgesic effects, and secondarily investigate if such effects are local or widespread.

Detailed Description

Healthy volunteers will be recruited and randomized into 3 groups. A 2Hz mobilisation group, a 0,5Hz mobilisation group and a Placebo group. The pressure pain threshold will be measured before, immediately after and 15 minutes after the intervention.

Arm && Interventions

Group	Intervention	Description
0,5Hz mobilisation	0,5Hz mobilisation	A bilateral postero-anterior mobilisation applied to the fourth thoracic vertebra, at a 0,5Hz frequency.
2Hz mobilisation	2Hz mobilisation	A bilateral postero-anterior mobilisation applied to the fourth thoracic vertebra, at a 2Hz frequency.
Placebo	Placebo	A simulation technique, that mimic the other groups, in this case only manual contact will be applied, without any oscillation.

Primary Outcome Measures

Name	Time	Method
Pressure pain threshold	Change from baseline imediately after, and 15 minutes after the intervention	Pressure pain threshold will be measured in five anatomic points on the spine, upper and lower limbs
