This invention provides a mechanical lower extremity manipulation device to increase venous blood flow in lower extremities for the prevention of deep vein thrombosis (DVT), pulmonary embolism (PE), lower extremity edema, and other associated or related conditions. Foot plates pivoting on a base plate can be powered to provide a reciprocating action to the feet of a reclining patient. Straps can hold the patient's legs against the base plate so that the reciprocating action results in alternate planar flexion and dorsal flexion of the foot without movement of the leg in general. The resulting elongation and retraction of lower leg muscles can improve venous blood flow to reduce the risk of pathologies, such as DVT.

A stand-alone exercise apparatus includes a seat to support a user in a position thereon, and upper and lower body exercising assemblies which are configured for activation either sequentially of simultaneously to permit the concurrent exercising movement of his or her upper body area and lower body leg muscles, respectively, without necessitating that the user stop exercising when switching from upper body exercises to lower body exercises. The lower body exercising assembly includes a lower frame assembly which is operable to provide resistance exercise to the user's leg muscles, and which includes a selectively reciprocally movable pedal, platform or bar which is coupled to a suitable resistance mechanism and which is engageable by the user's feet and/or legs as they are moved together in unified movement to effect leg extensions or curls. The upper body exercising assembly includes one or more reciprocally movable frame members, hand pulleys or swing arms coupled to a resistance mechanism, and which are engageable by the user's hands and/or arms. The resistance mechanisms used to provide the selected resistance to the upper and lower exercising assemblies are operable independently from each other, and enable the user to select the degree of resistance to each of the upper and lower body exercising assemblies separately.

A knee rehabilitation exercise device with a right and left leg brace, a rear knee strap, an upper leg strap assembly, a lower leg strap assembly, a portable rear brace assembly and an elastic resistance band. The left and right leg brace members are each comprised of an upper member and a lower member rotatably pinned together at the area of the knee joint. The left and right leg braces are attached to the upper and lower leg strap assembly. The rear knee strap is attached to the left and right leg braces at the knee joint. When a user places the elastic band onto L hooks mounted on the upper and lower strap assembly and the rear brace assembly is placed between the rear of the user's knee and the elastic band, a resistive stretching is caused when the user straightens his leg which exercises and strengthens the user's leg muscles in the area of the knee joint.

In a method and a system of providing walking assistance and/or therapy to a person with impaired gait, electrical stimulation is applied to muscles of a leg that effect dorsiflexion and plantar flexion of the ankle of the leg. The timing of the electrical stimulation is determined from gait event signals developed from sensors under the heel and forepart of the foot of the other leg. In the method and the system, the electrical stimulation is enabled when the person is sensed to be active and is disabled when the person is sensed to be inactive. The method and the system are applicable to persons having unilateral or bilateral impairment of their walking ability.
