Insole Diabetic and Medical Insoles 1 — Questions and Answers
Question 1: Why are diabetic insoles considered a medical device rather than just a comfort product?
- They are more expensive
- They are prescribed to prevent diabetic foot ulcers and complications that can lead to amputation (Correct answer)
- They have a special logo
- They are only available in hospitals
Correct answer: They are prescribed to prevent diabetic foot ulcers and complications that can lead to amputation
Diabetic insoles are therapeutic devices prescribed to prevent pressure ulcers, infections, and amputations by redistributing plantar pressure in people with diabetes-related neuropathy.
Question 2: What is 'total contact casting' related to in diabetic foot care?
- A full body cast
- A technique to create perfectly fitted diabetic insoles by capturing total foot surface contact (Correct answer)
- A cast for broken bones only
- A casting method for athletic insoles
Correct answer: A technique to create perfectly fitted diabetic insoles by capturing total foot surface contact
Total contact principles in diabetic insole fabrication involve capturing the entire plantar surface to distribute pressure evenly, preventing concentrated loading on any single point.
Question 3: Which material is commonly used in diabetic insoles for its pressure-distributing properties?
- Carbon fiber
- Plastazote foam (Correct answer)
- Rubber
- Hard leather
Correct answer: Plastazote foam
Plastazote foam is a cross-linked polyethylene foam widely used in diabetic insoles because it molds to the foot shape under body heat, distributing pressure very evenly.
Question 4: At what frequency should diabetic patients inspect their insoles and feet after walking?
- Once a year
- Daily — examining both feet and insoles for signs of excessive wear patterns or pressure spots (Correct answer)
- Only when pain occurs
- Weekly is sufficient
Correct answer: Daily — examining both feet and insoles for signs of excessive wear patterns or pressure spots
Diabetic patients with neuropathy must inspect their feet and insoles daily because loss of sensation means injuries can develop unnoticed, requiring visual checks to catch problems early.
Question 5: What does a high-pressure hot spot on a pressure plate scan indicate for diabetic insole design?
- The foot is healthy
- An area of concentrated pressure that must be offloaded in the custom insole design to prevent ulceration (Correct answer)
- The insole is too soft
- The scan equipment needs calibration
Correct answer: An area of concentrated pressure that must be offloaded in the custom insole design to prevent ulceration
A high-pressure hot spot indicates an area at elevated ulcer risk, guiding the orthotist to add a relief cutout or extra padding at that specific location in the custom insole.
Question 6: Which shoe characteristic is most important to pair with diabetic insoles?
- Fashionable design
- Extra-depth shoe with adequate room to accommodate the insole without creating new pressure points (Correct answer)
- High heel for posture
- Thin flexible sole
Correct answer: Extra-depth shoe with adequate room to accommodate the insole without creating new pressure points
Extra-depth diabetic shoes provide sufficient interior volume to accommodate protective insoles without compressing the foot, which is essential for preventing new pressure injuries.
