Teaching aid for spinal mobilization and manipulation therapy

摘要

A teaching aid for spinal mobilization and manipulation therapy is described which includes a first support on which is mounted a spinal model. A second support underlies the first support. A third support underlies the second support. The third support has a cavity into which the second support is telescopically received. Telescopic movement of the second support relative to the third support occurs when a force is applied to the first support. A load sensor is disposed between the first support and the second support whereby a force with which the first support is pressed toward the second support is measured. A plurality of springs are disposed between the second support and the third support to provide resistance to telescopic movement of the second support relative to the third support. A displacement sensor is secured between the second support and the third support whereby the displacement of the second support relative to the third support is measured. A microprocessor is linked to the load sensor and the displacement sensor. The microprocessor is programmed to receive signals from the load sensor and the displacement sensor, convert the signals into values, and compare the values as to the amount of displacement occurring and the amount of force being applied to a therapeutic range of values. Human readable feedback is provided as to whether the measured values for force and displacement are within the therapeutic range.
