What does the term 'plantar pressure mapping' refer to?

Plantar pressure mapping refers to a specific technology that measures how pressure is distributed across the sole of the foot during activities such as walking or running. This technique utilizes sensors placed in pressure-sensitive mats or insoles that capture real-time data as a person progresses through their gait cycle. Understanding the distribution of pressure can provide valuable insights into a person's foot mechanics and can help in diagnosing problems, designing orthotics, or customizing footwear to better support individual needs.

This process is crucial in pedorthics because it allows practitioners to identify areas of excessive pressure, which could lead to discomfort, injuries, or conditions such as diabetic foot ulcers. By analyzing this data, practitioners can develop targeted treatment plans or recommendations for footwear that alleviates pressure where it's needed most, thus enhancing comfort and function for the patient.

The other options do not accurately capture the essence of plantar pressure mapping; for example, the option relating to diagnosing arthritis does not focus on pressure distribution, while predicting foot sizes and shoe design measurements involve different areas of study without the specific focus on pressure distribution during gait assessment.
