Study Description
Brief Summary:
Physical therapists have traditionally included various forms of manual therapy among the therapeutic approaches to spinal pathologies. The aim of this study was to evaluate the effect of diaphragmatic stretching on spine and thoracic movement in healthy adults.

Condition or disease Intervention/treatment
Healthy Other: Diaphragm stretching. Other: Placebo.

Detailed Description:
Spinal pain is a well recognized condition associated with significant personal and community burdens. Recent studies estimated the prevalence between 6 and 22% in neck pain, from 4-72% in thoracic pain and from 1.0% to 58.1% in low back pain, which increases with age. During the last decades numerous researches have been conducted on stretching effects, evidencing an increased muscle control, flexibility and range of motion. The main purpose of this investigation is to examine the effects of diaphragm stretching in spine and thoracic mobility in healthy subjects in order to apply the results in a specifics pathologies in future studies.

Arms and Interventions

Arm Intervention/treatment
Experimental: Experimental group
43 people are recruited in order to the inclusion criteria for the study. They are healthy people. A diaphragm stretching technique was employed in this experimental group.
Other: Diaphragm stretching.
A manual technique of diaphragm stretching during 7 minutes. The participants were situated in a seated position.
Other Name: Manual technique
Placebo Comparator: Placebo group
37 healthy people were recruited in order to the inclusion criteria.
Other: Placebo.
Disconnected ultrasound was used for the 7 min as sham treatment
Other Name: Placebo

Outcome Measures

Primary Outcome Measures :
  1. Assessment of lumbar mobility [ Time Frame: up to 2 months ]
    Schober test is a flexion trunk test to evaluate lumbar spine mobility. During this test, while the patient is in the standing position, marks are made in the midpoint between the posterior superior iliac spines (PSISs) and 10 cm superiorly to this point.

Secondary Outcome Measures :
  1. Assessment of trunk mobility [ Time Frame: baseline, 2 months ]
    In Finger to floor test, the subjects were stood on a stool and asked to flex the trunk forward in order to reach as far as possible with both hands, without blending their knees.

  2. Cervical mobility [ Time Frame: baseline, 2 months. ]
    A Baseline Bubble Inclinometer, Fabrication Enterprises Incorporated, New York. USA, was used to measure de active range of motion of the cervical spine. The measurements were performed in two planes of movement, lateral flexion (frontal plane) the right and left side; and flexion-extension (sagittal plane)

  3. Abdominal and Thoracic Dimensions and Kinematics [ Time Frame: baseline, 2 months. ]
    Abdominal and thoracic dimensions and kinematics measurements can be used as an evaluative method for diaphragmatic breathing excursion to quantify possible alterations in thoracic capacity and abdominal and chest wall compliance as achieved by all expiratory and inspiratory muscles
