Description

A self-contained electronic device is described for controlling the limb load exerted by a patient in partial-weight-bearing walking exercise. The device measures the limb load with two removable load transducers attached to the sole of the patient's shoe, compares the load with two presettable thresholds, and emits audible biofeedback tones. A low-frequency tone is emitted when the load falls in the desired range, and a high-frequency tone is activated when the load exceeds the maximum load allowable for the patient. The device has accuracy of ±10% in all stages of the stance phase. Experimental results which demonstrate the effectiveness of the device in controlling the limb load are also presented.
