An exercising system and method for the treatment and rehabilitation of the paralyzed muscles of the legs. Stimulators and sensors are implanted in several of the main muscle groups of the legs. A computerized controller uses wireless signals for communications with the implanted stimulators and sensors. The person receiving the treatment sits on an exercise machine such as a stationery bicycle, a leg press, a rowing machine or other leg exercising machine. The controller determines the position of the legs and transmits a series of commands to the stimulators to provide functional electrical stimulation (FES) to the muscles of the legs, which move the legs in a cyclical or reciprocating manner, such as that needed to pedal a bicycle. Using data provided by the implanted sensors, the controller is able to adjust the stimulation commands sent to the muscles of the legs to control the amount of force exerted by the foot, to limit user fatigue and to keep the foot in a neutral position on the pedal or footrest. Users of the system who are partially paralyzed in the legs can receive an implanted EMG sensor and the controller can synchronize the stimulation of their paralyzed leg muscles with the user's own voluntary activation of their leg muscles.

A method and apparatus for the prevention of deep vein thrombosis (DVT), pulmonary embolism (PE), lower extremity edema, and other associated medical conditions by adjusting the temperature of the muscles of a foot or a leg, and / or applying vacuum or negative pressure to increase blood flow. A human extremity such as a leg is exposed to a negative pressure environment and / or a thermally controlled environment within a medical device. In one aspect, the device is portable. A thermal exchange unit and, optionally, a vacuum or negative pressure unit, are provided to increase blood flow and vasodilation. The device can be programmed by a controller in a manner to stimulate the muscles of the extremity to reduce pooling of blood therein.

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.

A mechanic's body support including first and second horizontally-oriented and spaced-apart base rails and first and second spaced-apart support rails. Each of the support rails has one end connected to a respective one of the first and second base rails. Each support rail also extends upwardly from and is in vertical alignment with the base rails for supporting a mechanic as he kneels in an elevated position over the engine compartment of a motor vehicle. A chest pad and a knee pad are mounted in spaced-apart relation between the support rails for securing the support rails in a fixed, spaced-apart relation, and for supporting the chest and knees of the mechanic while in the kneeling position, thus allowing the skeletal structure of the body to support the weight, rather than the back and leg muscles.

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.
