Abstract: Foot Alignment Socks are a uniquely designed adaptation of regular socks used to alleviate minor foot problems. Foot Alignment Socks differ from traditional socks in that there is no covered toe assembly. Instead the socks have four separators which fit in between the toes. They are cylindrical and sturdy yet soft and yielding as they are constructed from the same fabric as the body of the sock. The separators stretch and align toes into proper position in respect to the rest of the foot. This toe alignment counters the harmful effects of daily foot compression and stress caused by tight and ill-fitting shoes as well as relieving foot pain from excess walking, standing, jogging, or strenuous sports and activities. With consistent use Foot Alignment Socks soothe and straighten crooked and deformed toes. They are ideal as an over-night foot maintenance treatment.

Abstract: An exercise device has a central grip with a first and second end. Three peripheral handles are symmetrically disposed around a central grip.

The peripheral grip portions are parallel to the central grip. The central grip has three partially flattened sides respectively facing each of the three peripheral grip portions. The junction of any two sides forms a curved edge that fits comfortably in the joint of a human finger. The peripheral distance around the central grip is two to three times the peripheral distance around a peripheral grip portion. In various exercises, users can grip a peripheral grip portion by one hand, use both hands to grasp adjacent peripheral grip portions, or grasp the central grip.

Abstract: A method and apparatus for reliably positioning a 3-segment limb, such as a leg or arm for imaging and medical analysis, which can accommodate for the patient's “natural alignment”. The apparatus positions the limb in such a way that the position of the proximal segment is controlled while an known external torque is applied at a known rate to the distal segment. The location of each of the limb's three segments is recorded using either external or internal measurement techniques, and the relative motions between the proximal and intermediate segments are used in the orthopedic evaluation of the proximal joint. Furthermore, the relative motions between the intermediate and distal segments are used in the orthopedic evaluation of the distal joint. By applying a known torque at a known rate, clinicians will be provided with valuable information related to joint range of motion, stability, laxity, and compliance.

Abstract: The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet. Elliptical cross trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical cross trainers often use excessive pedal articulation which can overwork the ankle to achieve a longer stride. The present invention is an improved elliptical exercise machine capable of extended exercise with less pedal articulation that is more ankle friendly. One end of a foot support member has a pedal following elliptical motion while the other end is guided by an orbital link to drive an alternator and flywheel. The resulting pedal motion is foot friendly. Stride length can be adjusted.

Abstract: An exercise and physical therapy device using inertia and momentum to provide both resistance training and passive assisted movement for a user's foot or feet. A foot pedal is mounted for pivoting movement in a frame. The pivoting movement of the foot pedal is translated into rotational movement of a flywheel. As a user begins pivoting motion of the foot pedal, the flywheel provide resistance to this movement. The user may continue to use the foot pedal for resistance training. Once the flywheel is in motion a user may rest a foot or feet on the foot pedal and the rotational movement of the flywheel caused by the flywheel's momentum will cause pivoting motion of the foot frame. This presents passive assisted movement to a user's foot and legs until the momentum of the flywheel is dissipated.
