Which of the following is NOT one of the six classes of modalities?

• A. Cryotherapy
• B. Mechanotherapy
• C. Light therapy
• D. Aromatherapy

Answer: (D)

The main idea here is knowing the six primary classes of therapeutic modalities used in rehabilitation, which group methods by the physical mechanism they employ to influence tissue healing and function. Those six classes are typically described as cryotherapy, thermotherapy, hydrotherapy, mechanotherapy, electrotherapy, and phototherapy. Aromatherapy doesn’t fit into this framework because it relies on olfactory and psychological effects rather than a direct physical energy or mechanical modality that changes tissue properties in a measurable way. While it can provide comfort or mood benefits, it isn’t categorized as one of the core modalities used to achieve tissue-level changes, so it isn’t counted among the six.
