Software to automatically calculate, track, document and report limb volume changes in persons treated for limb edema and lymphedema.The software was "field-tested" by experienced therapists and nurses; it got rave reviews. Also, feedback from referring physicians and other health care providers has indicated that the printed/graphic reports of their patients progress has been extremely useful. They have recommended its use as a "gold-standard" for therapy progress documentation. The NEW version (LVP4.0) has MANY added and upgraded capabilities including the ability to incorporate scientifically validated hand and foot volumes as part of the overall limb volume assessment and a capacity double that of the previous version (LVP3.0).
