An orthotic apparatus for use in providing improved range of motion is provided which allows the amount of stretch to be hydraulically powered and measured by the device, but controlled by the user. Because the apparatus accurately calculates the amount of stretch, the user, together with the user's physician and therapist, can develop a rehabilitation plan based on accurate measurements. Progress is based on tangible results rather than the user's ability to tolerate pain. This knowledge provides the incentive the user needs to work toward and achieve the user's goal.

1. A device for manipulating the leg of a user, said device for use with a chair positioned atop a supporting surface such as a floor, said chair including at least two legs and an elongate cross member intermediate and connecting said two legs, said elongate cross member positioned a distance front said supporting surface when said chair is positioned atop said supporting surface, said device comprising:an elongate frame member having a longitudinal axis and a first and a second end, said first end configured to be supported by said supporting surface; a chair attachment device configured to attach said second end of said elongate frame member to said elongate cross member of said chair positioned a distance from said supporting surface, such that said elongate frame member is inclined relative to horizontal, said chair attachment device including a slot configured to accept said elongate cross member of said chair; a leg manipulating device movably and slidably attached relative to said elongate frame member along a substantially linear axis, said axis being substantially parallel to said longitudinal axis of said elongate frame member, said manipulating device including a leg supporting portion configured for selective attachment to said leg of said user, said leg supporting portion likewise configured to move along a substantially linear axis, said axis being substantially parallel to said longitudinal axis of said elongate frame member, said leg manipulating device configured to move relative to said elongate frame member while said elongate frame member has its said first end in contact with said supporting surface and said elongate frame member is stationary; and a control device operably associated with said manipulating device, said control device configured to be operated by said user while said user is sitting in said chair, such that said user may manipulate said leg while sitting in said chair by use of said control device to move said leg manipulating device relative to said elongate frame member while said elongate frame member is stationary and in contact with said support surface, but subsequently may detach said device from said chair for separate storage. 2. The device of claim 1 wherein said chair attachment device defines at least one hole configured to facilitate attachment of said attachment device to said cross member.3. A device for manipulating the leg of a user, said device for use with a chair positioned atop a supporting surface such as a floor, said device comprising:an elongate frame member having a longitudinal axis and a first and a second end, said first end configured to be supported by said supporting surface; a chair attachment device configured to attach said second end of said elongate frame member to a portion of said chair positioned a distance from said supporting surface, such that said elongate frame member is inclined relative to horizontal; a leg manipulating device movably and slidably attached relative to said elongate frame member along a substantially linear axis, said axis being substantially parallel to said longitudinal axis of said elongate frame member, said manipulating device including a leg supporting portion configured for selective attachment to said leg of said user, said leg supporting portion likewise configured to move along a substantially linear axis, said axis being substantially parallel to said longitudinal axis of said elongate frame member, said leg manipulating device configured to move relative to said elongate frame member while said elongate frame member has its said first end in contact with said supporting surface and said elongate frame member is stationary; a hydraulic pump and associated hydraulic fluid lines; and a control device operably associated with said manipulating device and including a pivoting lever operably associated with said hydraulic pump, said lever configured to be pivotably moved by the hand of said user, said control device configured to be operated by said user while said user is sitting in said chair such that pivoting of said lever by said user causes said hydraulic pump to provide a hydraulic pumping action configured to cause movement of said leg manipulating device; such that said user may manipulate said leg while sitting in said chair by use of said control device to move said leg manipulating device relative to said elongate frame member while said elongate frame member is stationary and in contact with said support surface, but subsequently may detach said device from said chair for separate storage.
