the variations thereof , but as exemplifications of the presently preferred embodiments described herein . many other ramifications and variations are possible within the scope of the concept of the first embodiment . such variations of the concept of the first embodiment could include design of shape , size , configuration , height of parallel peripheral elevations , width of channel between peripheral elevations , width and shape of peripheral elevation contact surfaces , contact surface modifications for comfort of patient , or modifications to enhance the therapeutic effect when used in conjunction with manual manipulation or manipulative surgery . even though the concept of the first embodiment stipulates intended use by a doctor educated and trained in the methods , techniques , and procedures of manual manipulation and manipulative surgery this should not be interpreted as a restriction for individual home - use or self - use by prescription for a patient as part of treatment protocol . thus the scope of the invention should be determined by the appended claims and their legal equivalents , and not by the examples given .
a portable device that provides a stable rigid platform with two parallel peripheral elevations and a channel in between that can be applied to the spine or pelvis of a patient placed in either a supine , sitting , or standing position , which the doctor uses to obtain therapeutic effects to correct spinal and pelvic disorders , conditions , and syndromes in conjunction with the application of manual manipulation and manipulative surgery beyond what can be done by using the hands alone .
