Study Notes
Introduction
- Therapeutic electrophysical agents (TEPA), or modalities, utilize physical energies like thermal, mechanical, electromagnetic, or light for therapeutic purposes.
- International Society for Electrophysical Agents in Physical Therapy (ISEAPT) defines TEPA as using electrophysical and biophysical energies for evaluating, treating, and preventing impairments, activity limitations, and participation restrictions.
Electrophysical Agents
- Classified by the type of energy delivered to soft tissues.
- Common types: thermal, electromagnetic, electrical, and mechanical.
Thermal Agents
- Conduction: Direct contact heat transfer from a higher temperature material to a lower temperature material.
- Examples: Hot packs.
- Convection: Heat transfer by movement of a fluid (air or water) from a source of heat.
- Examples: Whirlpool.
- Conversion: Changes non-thermal energy (mechanical, electrical, or chemical) into heat.
- Examples: Ultrasound therapy, diathermy.
- Radiation: Transfer of energy through electromagnetic waves without direct contact.
- Examples: Infrared lamps, microwave diathermy.
- Evaporation: Conversion of a liquid to gas or vapor as it absorbs heat.
- Examples: Vapor-coolant spray.
Contraindications and Precautions
- Contraindications: Situations where using a TEPA on a specific location or region of the body could be harmful.
- Precautions: Reflect situations where a patient has some risk of experiencing an adverse event.
- May require adjustment of treatment parameters (intensity, frequency), closer monitoring, and proactive measures to mitigate risk.
Documentation
- Treatment parameters, patient response during and between sessions, and any modifications to goals or the treatment program should be documented accurately.
Therapeutic Efficiency and Effectiveness
- Therapeutic Efficiency: Doing things correctly and following recognized standards to minimize waste of time, effort, or skill.
- Therapeutic Effectiveness: Focuses on achieving therapeutic objectives and solving problems. It emphasizes evidence-based practice (EBP) and using the best available evidence to guide clinical decision-making.
Cost-benefit and Risk-benefit Ratios
- Practitioners must analyze the effectiveness of different TEPA to determine if benefits outweigh costs and determine the overall value for the money.
- Also, analyzing the risk-benefit ratio to determine if the benefits of using a TEPA outweigh potential risks for the patient.
Using the Right Outcome Measures
- Evaluating the effectiveness of TEPA requires using appropriate measures to assess their effectiveness.
- Choosing appropriate measurement techniques linked to the correct diagnoses and stages of healing is crucial for determining the appropriateness of TEPA for each patient.
Delivery of Electrophysical Agents
- The focus has shifted from just "doing the thing right" to "doing the right thing."
- Physiotherapists are increasingly prioritizing therapeutic effectiveness while still considering therapeutic efficiency.
- It is crucial to understand the physiological and clinical reasoning behind the choice of a TEPA.
