Plantar thermometry and clinical monitoring FAQ
Clear guidance on diabetic foot temperature monitoring, PodiaScan’s non-diagnostic role and the PS-CLIN-2026-V1 practice-integration framework.
What is diabetic foot temperature monitoring (plantar thermometry)?
Diabetic foot temperature monitoring, often called plantar thermometry, records skin temperatures at defined sites on both feet. Comparing matching left and right sites may help a home user and their clinician notice local skin temperature variance that warrants review. It complements visual checks and professional assessment; it does not diagnose tissue damage or predict ulceration on its own.
How does PodiaScan use the 2.2°C temperature-difference threshold?
PodiaScan compares seven matching sites on each foot. When a difference reaches 2.2°C (4.0°F), the diabetic foot temperature tracking app marks that site for attention. The result is a prompt to follow the agreed care plan and seek clinical advice where appropriate, not proof of inflammation, impending injury or a diagnosis. Any treatment or offloading decision remains with a qualified healthcare professional.
What is the PS-CLIN-2026-V1 framework?
The PS-CLIN-2026-V1 framework is PodiaScan’s proposed 12-week practice-integration pilot for evaluating how plantar thermometry software may fit into podiatry and orthotic workflows. Participating practices can introduce suitable home users to structured temperature logging, review trends and assess whether the communication process supports their existing clinical oversight. The framework does not set diagnostic thresholds or replace local clinical protocols.
Can an app help prevent diabetic foot ulcers and lower-limb amputations?
No app can guarantee that it will prevent diabetic foot ulcers or lower-limb amputations. A home foot temperature monitor for diabetes can support a regular checking routine and make recorded changes easier to share with a linked clinic. PodiaScan supports remote patient monitoring for foot-ulcer risk by organising readings and communication; clinicians remain responsible for assessment, diagnosis and treatment.
Is PodiaScan a diagnostic medical device?
PodiaScan is presented as a non-diagnostic progressive web application (PWA): a data-logging canvas and remote communication aid that complements standard clinical oversight. It organises bilateral temperature readings, trends and home-user records. It is not a diagnostic service, does not provide limb salvage data logging as a clinical determination, and must not replace examination by a qualified healthcare professional.
