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.


Condition or disease Intervention/treatment Phase
Spine Stiffness Other: 2Hz mobilisation Other: 0,5Hz mobilisation Other: Placebo Not Applicable

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.

Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Investigator, Outcomes Assessor)

Official Title: A Preliminary Investigation Into the Immediate Effects of Different Rates of Thoracic Mobilization on Pressure Pain Thresholds in Asymptomatic Individuals
Study Start Date : March 2014
Actual Primary Completion Date : July 2014
Actual Study Completion Date : July 2014

Arm Intervention/treatment
Experimental: 2Hz mobilisation
A bilateral postero-anterior mobilisation applied to the fourth thoracic vertebra, at a 2Hz frequency.
Other: 2Hz mobilisation
This intervention will be applied for 3 sets of 1 minute, with 1 minute rest period in between each set.
Other Name: Bilateral postero-anterior thoracic mobilisation

Experimental: 0,5Hz mobilisation
A bilateral postero-anterior mobilisation applied to the fourth thoracic vertebra, at a 0,5Hz frequency.
Other: 0,5Hz mobilisation
This intervention will be applied for 3 sets of 1 minute, with 1 minute rest period in between each set.
Other Name: Bilateral postero-anterior thoracic mobilisation

Placebo Comparator: Placebo
A simulation technique, that mimic the other groups, in this case only manual contact will be applied, without any oscillation.
Other: Placebo
Intervention that mimics the experimental procedures
Other Name: Manual contact without oscillation




Primary Outcome Measures :
  1. Pressure pain threshold [ Time Frame: 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
