Which question assesses feasibility of delivering the modality to target tissues?

• A. Can you effectively deliver the modality to the target tissues?
• B. Are there contraindications?
• C. What is the stage of healing?
• D. What are the treatment goals?

Answer: (A)

Feasibility of delivering the modality to the target tissues is being tested. Before using a physical agent modality, you must confirm you can actually reach the tissues with the required energy and parameters without causing harm. This depends on depth and attenuation of tissues, the modality’s delivery method (for example, depth penetration and coupling requirements), equipment capabilities (power, applicator size, settings), and patient-specific factors (edema, body composition, scar tissue). If those barriers prevent delivering adequate energy to the target, the treatment isn’t practically feasible.

The other considerations deal with safety and clinical context rather than delivery practicality: contraindications identify factors that prohibit treatment due to risk, the stage of healing guides when a modality is appropriate, and treatment goals define what you’re aiming to achieve, not whether you can physically deliver the modality.
