Adult and Adolescent Asthma

  • Asthma is a long-term disease that causes inflammation and swelling of the airways. This results in narrowing of the airways that carry air from the nose and mouth to the lungs.

    Asthma symptoms include trouble breathing (shortness of breath), wheezing, coughing, and tightness or pain in the chest. Symptoms can be triggered by different things for different people. Allergens, like dust or pet dander, are common triggers. Some people also develop asthma symptoms in response to certain foods or to exercise.

Chronic Cough

  • A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children.

    A chronic cough is more than just an annoyance. A chronic cough can interrupt sleep and leave those who suffer from it feeling exhausted. Severe cases of chronic cough can cause vomiting, lightheadedness, and even rib fractures.

Chronic Obstructive Pulmonary Disease (COPD)

  • Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. It's typically caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions.

    Emphysema and chronic bronchitis are the two most common conditions that contribute to COPD. These two conditions usually occur together and can vary in severity among individuals with COPD.

Sleep Apnea

  • Sleep apnea is a common sleep disorder that causes frequent pauses in breathing during sleep. Most people with sleep apnea experience symptoms such as loud snoring and daytime sleepiness. The two main types of sleep apnea are obstructive sleep apnea (OSA) and central sleep apnea (CSA).

    In OSA, a narrowing of the airway during sleep leads to breathing disruptions. In CSA, the breathing disruptions are caused by a lack of communication between the brain and the muscles involved in breathing.

    These breathing interruptions reduce the quality of sleep and, if left untreated, can lead to potentially serious health consequences.

  • You may eligible to participate if you have been diagnosed with sleep apnea and are unable to use a CPAP.

Type 2 Diabetes

  • Diabetes is a chronic condition that affects the way the body processes blood sugar (glucose). This long-term condition results in too much sugar circulating in the blood. Eventually, high blood sugar levels can lead to disorders of the circulatory, nervous, and immune systems.

    In type 2 diabetes, there are primarily two problems. First, the pancreas does not produce enough insulin — a hormone that regulates the movement of sugar into the cells. Second, cells respond poorly to insulin and take in less sugar.

  • You may be eligible to participate if you have uncontrolled type 2 diabetes and are on oral medication with cardiovascular risk.

Plantar Fasciitis

  • Plantar fasciitis is a common foot condition characterized by pain and inflammation in the plantar fascia, a thick band of tissue that runs across the bottom of your foot. It typically causes stabbing pain near the heel, especially when taking the first steps in the morning or after long periods of rest. Risk factors include repetitive stress, high-impact activities, and tight calf muscles. Treatment often involves rest, stretching exercises, orthotic devices, and occasionally, corticosteroid injections or surgery in severe cases.

  • You may be eligible to participate if you have had pain in one foot for more than 6 months, and conservative treatment has failed.
