Abstract: The invention provides a multi-dimensional broad-spectrum clinical in-situ testing equipment designed to evaluate the material properties of plantar soft tissue. The equipment comprises the following features: 1. A testing table with a designated area corresponding to the sole of the foot; 2. A vertical reciprocating stress-strain testing unit mounted on the testing table, for applying vertical tensile and compressive stresses to the plantar and measuring the stress-strain responses; 3. A shear stress-strain testing unit, mounted on the testing table, for applying shear stresses to the plantar and measuring the stress-strain responses; 4. A torque stress-strain detection unit, positioned on the testing stage, for applying torque to the plantar and measuring the stress-strain responses; 5. A lifting mechanism that facilitates the vertical movement of the three testing units.
