Abstract: The present invention describes methods and devices comprising magnetic, radio frequency burst, and light stimulation to modulate muscle contraction. The magnetic stimulation may be delivered to the muscle using one or more coils that is placed transcutaneously. The methods and devices are useful to treat a number of conditions or disease conditions, including for example, gastroesophageal cramps and sphincter leakage.

Abstract: A body surface compression device for generating cyclical or constant compressions for medical purposes. Compression is accomplished using pneumatic actuated artificial muscle in combination with a belt placed around a body part. Both artificial muscle shortening and pneumatic expansion are used for compression. A unique useful property of this system is the length-tension characteristic similar to natural muscle which reduces applied compressive force proportionally with the level of volume compression of the body part. This property as well as a uniformly applied compression over the body part allows compression to be accomplished in a way which resembles natural muscle activation and minimizes overall abnormal stress on the body part.

Abstract: Exercise apparatus wherein subject constraints such as supine position or joint stress can be accommodated to permit the maximum achievable exercise level. Provision for simulating limb muscle contraction for postural upright support is made through the use of elastic actuating members while in a non-standing position. Joint stress limitation can be accomplished by selection of the elasticity of these members. Apparatus materials and configuration can be selected to minimize interference in a magnetically sensitive enviornment to permit diagnositc biomagnetic imaging during exercise stress testing.
