Training Special Populations

Treating and working with individuals with specific medical or physical issues typically fall into the category of “Special Populations.”

Issues include chronic diseases such as asthma and hypertension or it may be a disability such as amputation or spinal cord injury.

Sometimes, people are considered part of a special population due to a transient condition such as pregnancy or childhood. There are instances when individuals may belong to multiple groups and consequently, designing exercise programs for these people takes an individualized approach as each person will have their own set of specific needs.

Generally, our society places a much greater emphasis on curing diseases. Those with a chronic disease that don’t have any current opportunities for a cure are often shuffled away from restorative opportunities. Health insurance programs lack coverage for palliative treatment resulting in decreased opportunities for these individuals to participate in programs that preserve function and improve well-being.

One of the challenges is that many people fit multiple categories of dysfunction and there is no empirical evidence on specific dose type and duration of the exercise.
