Abstract
A device for monitoring force being applied by a wearer thereof to the wearer's foot, as during walking. The device is contained within a shoe-like structure which can be worn by a recuperating injured person or a person recovering from surgery, etc. The device includes a pressure sensitive element that produces an electrical signal that is related to the force, with this signal being used to alert the wearer when a force in excess of a preselected value occurs. Further, this signal can be used as input to data recording and analysis equipment. The signal transmission can be by direct wire connections, or via radio transmission. A vibratory motion is of particular value to alert the wearer of the point where the excess force occurs. The alerting device can be contained within the shoe, or in other apparatus utilized by a patient. Through the use of this device, a recovering patient will know how much weight to place on the leg in order to achieve maximum healing value.
