Therapeutic exerciser with regulatable hydraulic torsional resistance
Abstract
Abstract A THERAPEUTIC EXERCISER FOR ACTIVE EXTERNAL ADDUCTIVE AND ABDUCTIVE ROTATION OF ANKLES, KNEES AND HIPS FURNISHES UNIFORM TORSIONAL RESISTANCE THROUGHOUT THE COMPLETE RANGE OF MOVEMENT THEREOF. THE EXERCOSER INCLUDES A PAIR OF FLOOR MOUNTED BASED MEMBERS AND A ROTATABLE FOOTRECEIVING MEMBER PIVOTALLY MOUNTED ON EACH BASE MEMBER. HYDRAULIC CYLINDERS MOUNTED IN EACH BASE MEMBER AND OPERATIVELY ATTACHED TO EACH FOOT-RECEIVING MEMBER SUPPLY CONSTANT TORSIONAL RESISTANCE TO EACH SUCH MEMBER THROUGHOUT THE FULL RANGE OF ADDUCTIVE AND ABDUCTIVE ROTATION THEREOF. A VALVE IS PROVIDED TO REGULATE THE AMOUNT OF RESISTANCE APPLIED BY THE CYLINDERS. THE EXERCISER FURTHER INCLUDES A SPRING OPERATED PLUNGER IN ASSOCIATION WITH EACH FOOT-RECEIVING MEMBER OPTIONALLY TO LOCK THE SAME WITH RESPECT TO ITS BASE MEMBER TO PREMIT ISOMETRIC EXERCISE OF THE LIMBS. THE DISTANCE BETWEEN BASE MEMBERS MAY BE EXTENDED SELECTIVELY TO VARY THE DISTANCE BETWEEN THE FOOT-RECEIVING MEMBERS.
