An apparatus and method to be used in CPR to promote diastolic filling of the heart in cardiac arrest situations during external or internal cardiac compression. A rigid backboard provided with a tilting apparatus to incline the backboard to a desired degree. The backboard can be also provided with a tiltable segment for forward head flexion. The body of a patient victim of cardiac arrest is placed supine over the rigid backboard and the backboard is tilted by actuation of the tilting apparatus to a desired angle thus positioning the patient with feet up and chest down, so that the lower extremities are higher than the abdomen and tilted down toward the abdomen, and the abdomen higher than the chest and tilted down toward the chest. Likewise, being the head flexed forward in respect to the remainder of the body, the head is positioned higher than the heart, and tilted down toward the heart. As a result of such a positioning, the blood in the venous system of the lower extremities, of the abdomen and head will be draining down toward the heart by gravity improving diastolic filling and ultimately will improve cardiac output with internal or external cardiac compressions being carried out with the patient maintained in such position.

A gunn cut glove construction in which a pre-curvature at selected locations, preferably around the joints, in the fingers is achieved by sewing wedges of material into cut portions of the gunn section so that the shortened fingers and larger back sections easily meet at and can be joined without the need to gather or moccasin material resulting in the shape of the finger being such that it curves forward towards the palm section. Increased volume at the fingertips of a gunn cut construction glove is achieved by darting the palm side pieces of fingers proximate the fingertips. In addition, to reduce the inflexibility of gloves when curled into a fist, an elliptical piece is removed from the palm portion of the glove and the sides of the elliptical piece are sewn together along a seam.

An apparatus and a method for combiningly performing four important exercises localized to the lower back with the addition of weight resistance: a) the rotation or torsion of the lower spine and the lower back muscles; b) the bending of the spine forward and the exercising of abdominal muscles; c) the bending of the spine rearward and the exercising of the lumbar and erector muscles; d) the stretching and self-postural adjustment of the spine. The user performs the four exercises in the horizontal position with both legs in raised position. A swinging member accommodates the legs and allows the swinging, side-to-side motion of the legs.

The present invention discloses an ankle foot orthosis device that is adjustable to a patient's drop foot. The device may include, inter alia, a foot-support that is sized to fit into a corresponding patient's footwear; an elongate member that is mechanically coupled to the foot-support; and a lower leg holder that is coupled to the elongate member.

An exoskeleton includes two torque generators, two thigh links, and a supporting trunk rotatably coupled to the thigh links. When a wearer bends forward in the sagittal plane such that the supporting trunk extends beyond a predetermined angle A with respect to vertical, at least one of the torque generators imposes a resisting torque between the supporting trunk and a corresponding thigh link, thus imposing a force onto a wearer's trunk and thighs to aid in supporting the wearer in a bent position. The exoskeleton may include an active or passive means for actuating the generators. When the supporting trunk does not extend beyond the predetermined angle A, the torque generators do not impose resisting torques between the supporting trunk and the thigh links during the entire range of motion of the thigh links, thus enabling a wearer to walk, run and sit without constraint while in an upright position.
