The purpose of this study is to determine if the use of a respiratory resistance trainer
will increase respiratory muscle strength, improve sleep quality and improve quality of life
in individuals with spinal cord injury.
Hypothesis: Use of the respiratory resistance trainer will improve respiratory muscle
strength, improve sleep quality, and improve quality of life among individuals with spinal
Individuals with spinal cord injury experience varying degrees of reduced muscle function.
Those individuals with high level spinal cord injury, cervical region, may experience
reduced diaphragm function. This reduction in function may affect daytime activities as well
as sleep quality. Sleep quality in people with spinal cord injury is considered to be worse
than sleep quality in the general population. The use of respiratory resistance training
devices has been shown to increase muscle strength in people with spinal cord injury. There
have been not studies to document potential improvements in sleep quality among individuals
with spinal cord injury following respiratory resistance training.
