CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of the following provisional application, which is hereby incorporated by reference in its entirety: U.S. Provisional Application 61/372,647, filed Aug. 11, 2010. 
    
    
     BACKGROUND 
     1. Field 
     The invention relates to methods, devices, and apparatuses for preventing and alleviating body pain and promoting body alignment. In particular, the invention provides one or more cushions adapted to be mounted to, or otherwise secured to, or in contact with a subject&#39;s body or clothing in order to facilitate proper alignment of the body including but not limited to the spine, hips, pelvis and trunk while also facilitating relaxation of the user&#39;s muscles, as well as promoting body alignment, blood circulation, and other benefits while sleeping or resting. 
     2. Description of the Related Art 
     Sleep problems and lower back pain (LBP), and body pain are serious issues. For example, patients suffering from back pain create significant health-care expenses and the economic impact of LBP is also great. Further, sleep problems such as sleep apnea, snoring and aspiration may be the result of LBP. Moreover, women who are pregnant, those suffering from or recovering from injury, the elderly and many others may experience LBP, various sleep problems, body pain, poor circulation, and various other issues. 
     There are many products and services that purport to solve these problems. Among a class of solutions for the above-mentioned issues, are body pillows. Existing body pillows, however, have various disadvantages. For example, they are unable to remain functional, i.e., engaged with the body of the user, when the user changes sleep positions, and may not provide support in needed areas. Indeed, such pillows may cause further disturbed sleep by forcing users to be consciously aware of the body pillow or not supporting the proper areas. Furthermore, traditional body pillows are generally heavy and/or bulky, thereby taking up extra space in the bed and thus encroaching upon or interfering with a user&#39;s desired sleep position once he/she changes position. 
     Thus, there is an essential need for devices, methods, and apparatuses which provide a cushion to align the spine, the lower extremities, and or the body during sleep. Further there is a need to achieve an aligned body trunk, cushioning of the knees and medial malleoli and to support important areas of the user&#39;s body. Such a body positioning aid is also needed to remain in position with the user throughout the user&#39;s sleep or resting period. Such a body positioning aid may enable users to receive various benefits of the body positioning aid.

The positioning aid may employ one cushion to be placed on a user&#39;s leg and between the user&#39;s legs or the positioning aid may be comprised of two cushions, one on each leg of the user fastened by various means. In embodiments described herein, a cushion  208  without a cushion covering  212  may be used in place of the cushion and cushion covering  102 . 
     Referring to  FIG. 6 , a user in a side sleeping position  600  may use a positioning aid comprising two cushions and cushion coverings  100 . Such a positioning aid  602  may extend from the user&#39;s upper leg region  604  down to the user&#39;s medial malleolus  508 . In embodiments, the positioning aid  602  may extend only to cover the user&#39;s ankle such that the user may walk comfortably while wearing the positioning aid  602 . In embodiments, the positioning aid may be various lengths such that it covers the entire leg or various lengths of the leg. The positioning aid may also be made to accommodate various lengths to fit children and adults of various sizes. Each cushion of the pair of cushions and coverings  100  may be the same length as the other in the pair or the lengths may differ from the other. In embodiments, the cushions of the positioning aid may be any desired thickness to accommodate various user preferences and various weights of user&#39;s extremities. Further, in embodiments, the pair of cushions and coverings  100  of positioning aid  602  may be received by leg coverings  300  via a receiving pouch  402 , various fasteners, straps and the like. In embodiments, the pair of cushions and coverings  100  of positioning aid may be received by a user&#39;s bare leg. In various embodiments described herein, one or more cushions  208  without a cushion covering  212  may be used in place of one or more cushion and cushion coverings  102 . 
     Referring to  FIG. 11 , one or more cushions  208  or cushions and cushion covering  102  may be fastened to a user&#39;s bare leg in the event the user wishes to use the positioning aid without pants  404  as described in  FIG. 4 . The cushions may be fastened to a user&#39;s bare leg  1104  via straps or bands  1102 . Such bands may be fastened with hook and loops, buttons, snaps, clips and the like. In embodiments, the straps or bands  1102  may be elastic bands capable of securing to the user&#39;s leg without additional fastening means. In embodiments, the straps or bands  1102  may be made from satin, velvet or other material. In embodiments, the user may fasten a single cushion and cushion covering  102  to each bare leg to create a positioning aid similar to that of  FIG. 6  differing only in the lack of use of leg covering. In various embodiments described herein, one or more cushions  208  without a cushion covering  212  may be used in place of one or more cushion and cushion coverings  102 . 
     In the various embodiments described here, friction, including friction between one or more cushions, the cushion and the leg covering, the cushion and the user&#39;s leg and the like, may provide extra stability and support which may enhance the apparatus&#39;s ability to decrease or eliminate lower extremities misalignment which may consequently result in aligned spine and relaxed back muscle system. In various embodiments, the cushion covering  212  may be made from any material that may cause friction such as velvet normally used for memory foam pillows or other suitable fabric that creates friction. Other materials may also be used to obtain friction including polymers, materials having a polymer coating, latex, or textured materials. Such frictional material may be provided or otherwise applied to the cushions via a bag, sleeve, or other container. Such friction may help keep the positioning aid in place throughout a user&#39;s entire night of sleep and while turning and moving during sleep. This may decrease a user&#39;s awareness of the positioning aid by allowing the user to use the aid without having to be concerned with the positioning aid being shifted from its desired position. 
     In embodiments described above and those apparent to one skilled in the art, the positioning aid may be attached to a user in a manner consistent with providing more comfortable sleep. By way of example, such positioning aid may be fastened to the user in such as way as to provide a means of keeping it in place during a full period of sleep even while the user moves about his or her various sleeping positions. In this way, the user may not be subconsciously, consciously or otherwise aware of the positioning aid and may not be concerned with keeping it in place throughout his or her sleep period which may result in a more restful period of sleep. For example after putting the positioning aid in place, the user may not need to physically reposition the positioning aid during his or her sleep. 
     Referring to  FIG. 7 , the positioning aid may provide support to the user and aid in muscular, skeletal and overall body alignment. Referring to the skeleton  700  and when used in a position such as that represented by, but not limited to position  724 , the user may experience lower extremity alignment  708 , general body and lower back alignment  712  and hips and pelvis alignment  710 . Use of such positioning aid as described herein may reduce the: impact on the hips  714 , impact on the back muscle system  718 , impact on the sacroiliac joints  720 , and the impact on the lumber vertebrae and facet joints  722 . Further, use of positioning aids as described herein may reduce the impact at the knees  704  and ankles and medial malleoli  702  of the user. 
     Referring to  FIGS. 8A and 8B , a comparison of a user&#39;s body alignment is shown with and without use of the positioning aid  602 . As shown in  FIG. 8A , the side sleeper  800  may not experience general body alignment when in a side sleeping position. Further, the user may not experience lower back alignment and hip and pelvis alignment. Conversely, as depicted in  FIG. 8B , the side sleeper  800  may experience body alignment when using a positioning aid as described herein.

In embodiments, the cushion  1000  may be shaped to accommodate fastening to a leg. 
     Use of the positioning aid may allow the cushions to accommodate or provide cushioning to pressure points on the legs, such as the knees, medial knees, and medial malleoli, which in turn provides lower extremity alignment, body-lower back alignment, and hips and pelvis alignment. With respect to the medial malleoli, the cushions may extend a distance sufficient to accommodate the medial malleoli, such distance being beyond the end of the pajama bottom or other leg covering in embodiments. The cushions may be provided in a variety of sizes to accommodate different users. 
     In embodiments, the cushions may be secured to the inside surface of clothing, e.g. pajama bottoms such that the cushions contact the inside surface of the leg or to an outside surface of the pajama or leg covering. Alternatively, as discussed herein, the cushions may be directly secured to the leg of a user such that the pair of cushions oppose each other, while each contact the inside surface of the leg to which the cushion is attached. The cushions as described herein, cushion coverings, leg coverings, and pants as may be provided with mating zipper sections, Velcro® sections, snaps, hook and loop fasteners, buttons or combinations thereof in order to secure the cushions to the user and or the leg coverings/pants. Alternatively, each cushion may also be provided with a securing device as described below in connection with one-cushion embodiments. In embodiments, one cushion may be fastened to a leg covering while the other cushion is fastened directly to the leg. Any combination of fastening to the inside surface of the leg covering, the outside surface of the leg covering, and directly to the leg for the pair of cushions is contemplated by the invention. 
     In embodiments, utilization of low-density memory foam, or memory foam enables the positioning aid to achieve mechanics necessary for alignment of the back and lower extremities. In embodiments, the cushions may be configured to space apart, at a predetermined distance, the section of a user&#39;s leg extending from the user&#39;s knees or medial knees to the user&#39;s medial malleoli. In embodiments, the distance chosen to space apart the portions of the user&#39;s legs may be optimized for providing alignment to various parts of the user&#39;s body or for alignment of the user&#39;s entire body. In embodiments, the distance achieved by the cushion between the user&#39;s knees may be 4 inches. In embodiments, the distance achieved by the cushion between the user&#39;s medial malleoli may be 4 inches. The memory foam acts also as an inter-leg cushion. Friction, including friction between the cushion, the pajamas and the cushions themselves provides extra stability and support as well as to eliminate lower extremities misalignment which and consequently results in aligned spine and relaxed back muscle system. The cushions may be provided with a material that provides friction, such as a velvet normally used for memory foam pillows or other suitable fabric. Other materials may also be used to obtain friction including polymers, materials having a polymer coating, latex, or textured materials. Such frictional material may be provided or otherwise applied to the cushions via a bag, sleeve, or other container. In embodiments using bags, containers, or sleeves, such bags, containers, or sleeves may be of a standard size that can accommodate varying sizes of the cushions.
