Effect of Rib Mobilization and Diaphragm Release Techniques in Patients With Non-Specific Neck Pain

The RMT, adapted from Henderson et al10 and Abdelaal et al,15 was carried out in 2 different participant positions: supine and seated. In the supine position, the therapist was placed next to the participant and positioned the last 4 fingertips of both hands at the rib angles. The therapist mobilized the costal angles in the postero anterior direction accompanying the participant's normal inspiration The movement was performed in 2 series of 10 respiratory cycles in each hemi thorax, with a 1-minute interval between sets.

The DRT was performed according to the protocol described by Rocha et al.13 In this protocol, the participant remains in the supine position so that the therapist is able to maintain manual contact with the bottom edge of the rib cage. During inspiration, the therapist exerts traction after the natural rib-cage movement, then deepens the manual contact and maintains the resistance exerted in the previous phase throughout exhalation. The technique was applied in 2 series of 10 deep respiratory cycles, with a 1-minute interval between the series, under the therapist's verbal command.
