PURPOSE: “Post-lift” (PL) is a manual technique which is supposed to increase tidal volume and to improve alveolar ventilation, and therefore, to alleviate dyspnea. The purpose of this study was to verify the effect of PL on tidal volume and thoracic wall mobility.
METHODS: Twenty healthy subjects (20.8 ± 0.6 years of age) were studied. PL was performed to the subjects at supine position by a trained therapist. During breathing at rest, the lower back was gently lifted up on inspiratory phase, and restore on expiratory phase for 3 minutes. During PL, tidal volume was measured using flow sensor (linear pneumotachometer-3813, Hans Rudolph Inc., U.S.A) and thoracic wall movement at the xiphoid level using a commercially available apparatus (Takei Equipment Co., Japan).
RESULTS: During PL, the tidal volume was significantly increased from 0.74 ± 0.42 L to 1.13 ± 0.68 L (p<0.05). After PL, the tidal volume returned toward the baseline, but was still kept higher (0.81 ± 0.47 L, p<0.05). The thoracic wall mobility significantly increased from 0.14 ± 0.15 cm to 0.63 ± 0.55 cm during (p<0.01). After PL, it also kept higher (0.56 ± 0.47 cm, p<0.01) than the baseline.
CONCLUSIONS: These findings confirmed the beneficial effects of the PL on tidal volume and thoracic wall mobility.
CLINICAL IMPLICATIONS: PL is a possible choice of physical therapy for patients with respiratory dysfunction. Further studies, especially PL trials on patients with diseases, are needed for the real practical use.
