Modality
A therapeutic agent or physical intervention used to achieve specific treatment goals, such as heat, cold, or electrical stimulation.
Full Definition
In physical therapy, modalities are passive treatment interventions that prepare tissues for active treatment or provide pain relief. Common modalities include thermal agents (heat/cold), electrical stimulation, ultrasound, and mechanical devices. Documentation must specify the type of modality, parameters used, duration, and patient response. Proper usage in clinical writing requires understanding that modalities supplement but do not replace active therapeutic interventions. Insurance documentation often requires justification for modality use.
Usage
Usage note: Distinguish from 'intervention' - modalities are typically passive treatments.
