Goal: Walk one mile as quickly as possible. Execution: We suggest that you DO NOT attempt this test until you are routinely walking for 15 to 20 minutes several times per week. Do not perform this test on a treadmill, as it will skew your results. Warm up by walking slowly for 3-5 minutes.
Causes of Nasal Valve Collapse. Plastic surgery to the nose, or rhinoplasty, is the most common cause of nasal valve collapse. Also, a nasal valve collapse can occur after trauma to the nose or nose surgery as the result of inflammation, enlarged tissue or even scar tissue.
This happens when the supporting cartilage of the nose weakens. Airflow becomes constricted in the area where the lower and upper lateral cartilage meet, which is called the nasal valve region. It is this narrowing that causes nasal obstruction, or geriatric rhinitis, in the aging population.
