Which condition is a contraindication for aquatic therapy due to safety concerns?

Uncontrolled seizures represent a significant contraindication for aquatic therapy primarily due to safety concerns. In an aquatic environment, the risk of a seizure occurring can pose a direct threat to both the person experiencing the seizure and their aquatic therapist. Seizures can lead to loss of consciousness and muscle control, which would be particularly dangerous if they occurred while in water, potentially resulting in drowning or injury.

In contrast, mild asthma, a common cold, and minor back pain typically do not present the same level of immediate risk in a pool setting. While asthma might require management during exercise, with appropriate precautions it does not inherently endanger the safety of the individual to the same degree. Similarly, common colds usually do not affect one's ability to safely participate in aquatic therapy, and minor back pain can often be managed effectively with proper aquatic therapy techniques.
