AI Technical Summary

Technical Problem

Existing sit-and-reach testing equipment cannot be precisely adjusted according to individual differences in leg length among test subjects, resulting in unstable fixation and affecting the accuracy and impartiality of test results.

Method used

An adjustable pressure plate seated forward flexion testing device was designed. The pressure plate can be switched between three different states through the adjustment component. Combined with the power component and locking unit, the pressure plate can be stably positioned and flexibly adjusted to ensure that the pressure plate is always aligned with the root of the thigh.

Benefits of technology

It improves the accuracy and fairness of test data, prevents knee bending, ensures the standardization of the testing process and the credibility of the results, and enhances the applicability and ease of operation of the equipment.
