- Abstract
- BackgroundThe respiratory cycle generates pressure gradients between chest and abdomen which help promote the circulation of venous blood, lymph, intra- and extracellular fluids. Thoracic manual therapy is widely used in osteopathic clinical practice with the aim to improve soft tissue state and joint mobility of the rib cage, thereby exerting a positive influence on chest wall mobility and pulmonary function. Whilst thoracic manipulation is often used in the context of patients presenting with chronic pulmonary disease, the use of manual therapy techniques may also be indicated in healthy individuals who are affected by postural adaptations resulting in chest wall restrictions. AimTo investigate the effect of a passive stretch technique applied to the pectoralis muscles on vital capacity of healthy individuals with protracted shoulder posture. MethodsSixteen healthy individuals (8 females, 8 males), aged 21-51 [30.5 ± 8.6, (mean ± standard deviation)] took part in a single intervention during which pre- and post-measurements of vital capacity, axillary chest expansion and acromial distance to treatment table as a measure of shoulder protraction were recorded. ResultsThe intervention resulted in a small mean increase in vital capacity across the whole sample. The increase was not statistically significant (p=0.055). An analysis by gender showed that the increase was statistically significant in male participants (p=0.023), but not in female participants (p=0.686). The intervention led to a significant reduction of acromial distance from treatment table and a significant increase in axillary chest expansion (p<0.001) in both genders. ConclusionA single application of the traction-and-hold technique has only a limited effect on vital capacity in healthy individuals. The technique leads to a significant reduction in the degree of shoulder protraction and improves chest expansion. Further studies are warranted to investigate any cumulative effects on vital capacity this technique may produce over a series of applications.
