When your breathing muscles are weakened from disease, surgery, or disuse, it can have a devastating impact on daily life. Impaired breathing may hamper your ability to be physically active and may make walking, climbing stairs, and even sleeping difficult. Respiratory muscle training (RMT) strengthens your respiratory muscles to help improve breathing as well as speech, swallowing, and cough strength.

Strength Training for Your Respiratory Muscles

Conditions Treated
Respiratory muscle training can help strengthen breathing, swallowing, and speech muscles affected by many conditions and treatments, including: 

Respiratory muscle training can also help improve breathing after a tracheostomy placement and, in some cases, can help wean ventilator support.

Personalized Treatment Plans
Our speech pathologists evaluate your condition and design a treatment plan that’s right for you. When appropriate, we can combine respiratory muscle training with traditional communication and swallowing therapies to ensure we provide you with the most complete care for your condition.

Treatments

Inspiratory Muscle Training

A small, handheld device provides resistance against inhalation. You inhale forcefully with the device in your mouth. Inspiratory muscle training, or IMT, is individualized to your current inspiratory strength and overall medical condition. The frequency of training, number of repetitions, and amount of resistance are adjusted as needed. 

Expiratory Muscle Training

A small, handheld device provides resistance against exhalation. You exhale forcefully into the device. As with IMT, expiratory muscle training, or EMT, is individualized to your current expiratory strength and overall medical condition. The frequency of training, number of repetitions, and amount of resistance are adjusted as needed.

Speech and/or Swallowing Therapy

We may recommend additional speech therapy and/or swallowing exercises to meet your specific needs.

Education and Counseling

We work closely with you to develop a plan that addresses your specific concerns, and we adapt the treatment plan based on your feedback.

Evaluation

Evaluations of your speech and/or swallowing will help determine whether respiratory muscle training is the right treatment for you. Evaluations may include:

Comprehensive Communication Evaluation
Speech, language, and cognition are tested with a physical examination, questionnaires, practical and functional information gathering, and standardized testing based on your individual needs.

Respiratory Pressure Manometry
Maximum inspiratory (breathing in) and expiratory (breathing out) pressures are tested by effortfully blowing and sucking into a handheld device.

Clinical Swallow Evaluation
Your provider will ask about your medical history as it relates to difficulty swallowing (dysphagia), learn more about your symptoms, and observe you swallowing foods and liquids.

Fiberoptic Endoscopic Evaluation of Swallowing
A flexible endoscope (a small camera with a light) is passed through your nose to your throat. You will swallow dyed foods and liquids while the camera is in place to show whether any food or drink enters your airway.

Videofluoroscopic Swallow Study (VFSS) or Modified Barium Swallow (MBS)
A speech-language pathologist and a radiologist administer this test to evaluate your swallowing function. Moving X-ray images of the mouth, throat, and esophagus are recorded while you try different swallowing positions and swallow a chalky liquid containing barium – a substance that makes your throat structures show up more clearly on an X-ray.
