Purpose: This study investigated the effects of respiratory muscle training posture on respiratory muscle activation in stroke patients and presented appropriate posture for the respiratory muscle training.
Methods: Thirty-six stroke patients were assigned to either a neutral training posture (n = 13), habitual training posture (n = 12), or side bending training posture (n = 11) group. Respiratory muscle training was conducted using an inspiratory muscle trainer. Each group was asked to adopt either a neutral, habitual, or side-bending posture during respiratory muscle training, which was performed for 30 minutes per day, 10 sets, 3 times per week, for a total of 6 weeks. After each session, external intercostal muscles and sternocleidomastoid muscle activity were measured via surface electromyography.
Results: The paretic or non-paretic side intercostal muscle differed significantly in the three groups, and the non-paretic side intercostal muscle was significantly decreased in the neutral training group. The non-paretic side sternocleidomastoid muscle differed significantly in the three groups, and the nonparetic side sternocleidomastoid muscle was significantly increased in the habitual training group.
Conclusion: A neutral posture, where appropriate spine and trunk alignment is maintained, is a more effective posture for respiratory muscle training for improving respiratory function in stroke patients.
