How accuracy is measured:
When walking on crutches, there is a moment during which the healthy leg is completely lifted off the ground and the entire load is distributed between the crutches and the injured leg. If we know the patient's weight, then we can "count" how much weight falls on the crutches, subtract it from the patient's body weight and get the amount of load that fell on the injured leg. Example: if the patient's weight is 80 kg and during a step he transferred 60 kg to crutches, then there was a pressure of 20 kg on the sore leg.
The idea of attaching smart tips to crutches was tested with real patients and, unlike insoles, it turned out to be:
1. More durable - 2 years of use; 2. Available to consumers of any age and shoe size; 3. Easier and cheaper to implement, which means our final product will be offered at an affordable price; 4. Fit the reusable model - after one patient has rehabilitated, the smart crutch tips can be used by another patient.
