Clinical Trial Summary

Stroke is the leading neurological disease in the world that causes long-term disability. The most common cause of disability after stroke is motor impairment resulting from brain damage which ultimately cause respiratory and functional limitation. Respiratory muscle weakness including the diaphragm leads to biomechanical change in respiration which can reduce vital capacity and total lung capacity of stroke patients. The weakness of diaphragm and abdominal muscle also leads to decrease in maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) in stroke patients.

Respiratory muscle training such as inspiratory or expiratory muscle training is commonly used to improve the respiratory muscle strength and function in stroke. However, it was reported that respiration is closely related to upper limb function because the muscle of upper extremities surrounds the dorsal muscle of trunk and in order to breath, the movement of trunk is necessary, which in turn is related to the movement of the upper limbs.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of baseline maximum inspiratory pressure	Maximum inspiratory pressure (MIP) will be measure using a hand-held mouth pressure device. Three maximal manoeuvres will perform and the highest value record. Indirect measure of respiratory (inspiratory) muscle strength, expressed in cmH20.	Baseline, Post-intervention ( 6 weeks)
Primary	Change of baseline maximum expiratory pressure	Maximum expiratory pressure (MEP) will be measure using a hand-held mouth pressure device. Three maximal manoeuvres will perform and the highest value record. Indirect measure of respiratory (expiratory) muscle strength, expressed in cmH20.	Baseline, Post-intervention ( 6 weeks)
Primary	Change from baseline ABILHAND	A questionnaire to assess active function of the upper limbs with 23 activities, rated as impossible, difficult or easy. The scale is scored through Rasch analysis, providing a total score ranging from -6 to +6, with higher scores indicating a lower degree of upper extremity impairment.	Baseline, Post-intervention ( 6 weeks)
Secondary	Change from baseline Stroke Impact Scale	A stroke-specific health status measure featuring 16 items capturing daily activities. This scale has 8 sub-scales, evaluating: strength, hand function, mobility, activities of daily living, emotion, memory, communication and social participation. Each is rated on a 0 to 100 range (100 corresponding to least impact of stroke). An overall score is also calculated (average of sub-scales).	Baseline, Post-intervention ( 6 weeks)
