[Purpose] The main purpose of this study was to identify the impact of rib cage joint mobilization and chest wall stretch on respiratory muscle tone and stiffness and chest expansion in stroke patients and to compare the effects of both interventions. [Subjects and Methods] Subjects were randomly assigned to a rib cage joint mobilization group (n=15) or a chest wall stretch group (n=15). Respiratory muscle tone and stiffness were measured using a myotonometer, and the chest expansion was gauged using a measuring tape. [Results] A significant difference was found on comparing the respiratory muscle tone and stiffness on the affected and sound side before intervention. Although both groups showed an increase in respiratory muscle tone and stiffness after intervention, no significant difference was found. A significant increase in chest expansion was observed; however, no significant difference was observed in the variations between the groups. [Conclusion] This study suggests that rib cage joint mobilization and chest wall stretch exercises can be used to increase chest expansion potential and respiratory muscle tone in patients with chronic stroke.
