Overview

Brief Summary

Question: Does manual diaphragm release change kinematics and respiratory function of elderly subjects? Design: Randomized controlled trial with concealed allocation and double-blinding.

Participants: 17 volunteers over 60 years old randomized into two groups: 09 in the Control Group (CG) and 08 in the Intervention Group (IG).

Intervention: The manual diaphragm release technique was used on the IG, in two sets of ten deep breaths, with a one minute interval between them. The CG underwent a sham protocol (light touch), with same sets and time of interval.

Outcome measures: The groups were evaluated using spirometry, manovacuometry and optoelectronic plethysmography (OEP), in that order, before and immediately after the intervention.

Outcomes

Primary Outcomes

Compartmental chest wall distribution

Time Frame: before first session

The analysis of the regional distribution of respiratory volumes was done with Optoelectronic plethysmography (BTS Bioengineering, Italy), in which 89 reflective markers were adhered to the skin of volunteers using hypoallergenic adhesives, on particular anatomical points of the chest wall and abdomen (Aliverti and Pedotti 2003). The device emitted an infrared light on the reflective markers which was captured by eight cameras around the room, allowing the spatial determination of each marker. Thus, changes in lung volumes were calculated at each of the three compartments of the rib cage: pulmonary or upper ribcage (Rc, p), abdominal or lower ribcage (Rc, a) and abdomen (Ab). After the first OEP evaluation, a nontoxic, hypoallergenic pen was used to mark the placement of the dorsal reflective markers allowing the patient to lay in supine for the manual technique or the sham. The markers were then placed at the exact same anatomical points for reevaluation.

Secondary Outcomes

  • Pulmonary Function(Before first session)
  • Maximal inspiratory and expiratory pressures(Before first session)
