Which principle informs PT interventions in wound care and tissue healing?

• A. Age of patient
• B. Phase of healing
• C. Time of day
• D. Color of wound

Answer: (B)

Focusing on the current stage of tissue repair drives how wound care is planned. Each phase has distinct cellular activity and goals, so the interventions are chosen to support progression through that stage rather than based on static factors like age, time of day, or wound color alone.

During the inflammatory phase, the priority is protecting the wound, controlling edema, preventing infection, and avoiding mechanical disruption, with gentle debridement only as appropriate. In the proliferative phase, granulation and new tissue formation dominate, so care aims to support tissue growth and epithelialization through appropriate moisture balance, selective loading, and dressings that promote a conducive healing environment. In the maturation or remodeling phase, collagen reorganizes to improve tensile strength, so therapy focuses on gradual loading, scar management, and functional reconditioning.

Age, time of day, or wound color can provide useful clues, but they don’t alone determine the treatment plan as effectively as identifying the phase of healing. Therefore, aligning interventions with the phase of healing guides effective progression and outcomes.
