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.

Conditions

Spine Stiffness

Keywords

Spinal mobilisation; Pressure pain threshold; Thoracic spine

Outcome Measures

Primary Outcomes (1)

• Pressure pain threshold

  Pressure pain threshold will be measured in five anatomic points on the spine, upper and lower limbs

  Change from baseline imediately after, and 15 minutes after the intervention

Study Arms (3)

2Hz mobilisation

EXPERIMENTAL

A bilateral postero-anterior mobilisation applied to the fourth thoracic vertebra, at a 2Hz frequency.

Other: 2Hz mobilisation

0,5Hz mobilisation

EXPERIMENTAL

A bilateral postero-anterior mobilisation applied to the fourth thoracic vertebra, at a 0,5Hz frequency.

Other: 0,5Hz mobilisation

Placebo

PLACEBO COMPARATOR

A simulation technique, that mimic the other groups, in this case only manual contact will be applied, without any oscillation.

Other: Placebo

Interventions

2Hz mobilisation OTHER

This intervention will be applied for 3 sets of 1 minute, with 1 minute rest period in between each set.

Also known as: Bilateral postero-anterior thoracic mobilisation

2Hz mobilisation

0,5Hz mobilisation OTHER

This intervention will be applied for 3 sets of 1 minute, with 1 minute rest period in between each set.

Also known as: Bilateral postero-anterior thoracic mobilisation

0,5Hz mobilisation

Placebo OTHER

Intervention that mimics the experimental procedures

Also known as: Manual contact without oscillation

Placebo
