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.
