  • Patent number: 5298013
    Abstract: A therapeutic leg and foot device comprising an L-shaped member having an elongated channel-like portion adapted to fit the posterior region of the lower leg and a foot portion extending integrally at right angles therefrom. The integral connection is curved to avoid contact with the patient's heel when the device is in place. The channel shape flattens out at the curved portion and is narrowed to promote the required flexing at this point. The device is constructed of resilient transparent acrylic plastic material which is resilient under a stress load but has sufficient rigidity to maintain a bed patient's foot in properly disposed position to prevent bed sores or drop foot. However, when used in the correction of drop foot, the foot portion is flexed away from the perpendicular to an obtuse angle with the leg portion to conform to the deformity. In this position, the device exerts a 30 to 50 lb. pressure on the foot area to bias the foot back into normal position.

  • Patent number: 5112296
    Abstract: A biofeedback activated orthosis for foot-drop rehabilitation is provided including a lifting mechanism, a control circuit, a muscle activity sensing mechanism, and an electrogoniometer. The lifting mechanism lifts a foot through the swing phase of a gait cycle by way of a drive motor mechanism which pulls a cable passing between a foot brace and a shin brace. The drive motor mechanism allows the cable to unwind upon heel-strike by way of a slip coupling. The drive motor mechanism is controlled by a control circuit which assimilates and processes an incoming electromyographic (EMG) signal from the muscle activity sensing mechanism detected by EMG electrodes placed on the skin above the dorsiflexor muscles of the user. The control circuit also processes a leg position information signal obtained by a radial resistor attached to a knee brace strapped to the knee for sensing the angular position of the lower leg.
