Toe joint mobilization apparatus

An apparatus for passively mobilizing and imparting plantarflexion and dorsiflexion motion to a metatarsophalangeal (MTP) joint of a single toe of a human foot, comprising:

• a substantially non-deformable cylindrical roller member having a first curved surface for facilitating the rolling of said member on a firm surface, and a second curved surface adapted to receive at least a portion of the plantar portion of a human foot including at least a portion of the ball of the foot and at least one to-be-treated toe;
• means for receiving and retaining a to-be-treated single toe attached to said second curved surface, said receiving and retaining means including a toe base block which is shaped and adapted to receive and grasp a to-be-treated single toe;
• at least one flexible toe strap positioned adjacent said receiving and retaining means to secure a to-be-treated single toe within said receiving and retaining means;
• and
• means for retaining the heel of the user to prevent sliding motion between a user's to-be-treated single toe and said cylindrical roller, said means for retaining the heel of the user being attached to said cylindrical roller;
• whereby, as said cylindrical roller member is rolled in a forward direction on its said first curved surface a single to-be-treated toe secured within said means for receiving and retaining a to-be-treated single toe is pulled downward due to the curvature of said first surface of said member to thereby impart plantarflexion motion to the MTP joint of a secured single to-be-treated toe, and as said member is rolled in a backward direction, a secured single to-be-treated toe secured to said means for receiving and retaining a to-be-treated single toe is pushed upward due to the curvature of said first surface of said member to impart dorsiflexion motion to the MTP joint of the secured single to-be-treated toe.

An apparatus for mobilizing and imparting plantarflexion and dorsiflexion motion to a metatarsophalangeal (MTP) joint of a single toe of a human foot, comprising:

• a substantially non-deformable spherical member having a first curved surface for facilitating the rolling of said member on a firm surface, and a second curved surface adapted to receive at least a portion of the plantar portion of a human foot including at least a portion of the ball of the foot and at least one to-be-treated toe, wherein said second curved surface includes a trough formed in said second surface adapted to receive a single to-be-treated toe, and wherein said second curved surface further includes a ramp, said ramp being adapted to raise a single to-be-treated toe to a selected angle relative to said second surface;
• and
• a retainer adapted to secure a single to-be-treated toe to said second surface, said retainer attached to said second surface of said member, wherein said second surface of said member includes first and second means for receiving said retainer, and wherein said retainer includes a flexible loop strap having a first end attachable to said first receiving means and a second end attachable to said second receiving means of said member, and a middle section adapted to be wrapped snugly around a single to-be-treated toe to secure such a toe to said member when said first and second ends are attached to said first and second receiving means;
• whereby, as said spherical member is rolled in a forward direction on its said first curved surface a single to-be-treated toe secured within said trough is pulled downward due to the curvature of said first surface of said member to thereby impart plantarflexion motion to the MTP joint of a secured single to-be-treated toe, and as said member is rolled in a backward direction, a secured single to-be-treated toe secured to said ramp is pushed upward due to the curvature of said first surface of said member to impart dorsiflexion motion to the MTP joint of the secured single to-be-treated toe.

An apparatus for mobilizing a metatarsophalangeal (MTP) joint of a human foot, comprising:

• a member having a first curved surface for facilitating the rolling of said member along a selected axis, and a second surface adapted to receive the plantar portion of a human foot including at least a portion of the ball of the foot and at least one toe;
• a retainer attachable to said member for securing a single to-be-treated toe to said second surface;
• a track adapted to receive said curved surface of said member for guiding said member to ensure that said member moves along said axis, said track having a first end and a second end;
• and
• an elongated heel guide having a first end and a second end, said second end of said elongated heel guide attached at an angle to said first end of said track said heel guide having a longitudinal groove formed therein for receiving and guiding the heel of the foot of a user as said member is rolled in a backward direction;
• whereby, as said member is rolled in a forward direction along said selected axis, the secured to-be-treated single toe is pulled downward due to the curvature of said first and second surfaces of said member to thereby impart plantarflexion motion to the MTP joint of the secured to-be-treated single toe, and as said member is rolled in a backward direction the secured to-be-treated single toe is pushed upward due to the curvature of said first and second surfaces of said member to impart dorsiflexion motion to the MTP joint of the secured single toe.

A method for passively exercising a metatarsophalangeal (MTP) joint of a human foot, comprising the steps of:

• providing a member having a first curved surface and a second curved surface;
• placing the forward portion of the foot including at least a portion of the ball of the foot and at least one to-be-treated toe onto said second surface;
• securing a single to-be-treated toe to said second surface using a retainer;
• and then
• selectively rolling said member in a forward direction relative to the foot to cause the secured single toe to be pulled downward due to the curvature of said first and second surfaces, thereby passively imparting plantarflexion motion to the MTP joint of the secured single toe, or selectively rolling said member in a backward direction relative to the foot to cause the secured single me to be pushed upward due to the curvature of said first and second surfaces, thereby passively imparting dorsiflexion motion to the MTP joint of the secured single toe.

An apparatus for passively mobilizing and imparting plantarflexion and dorsiflexion motion to a metatarsophalangeal (MTP) joint of a single toe of a human foot, comprising:

• a substantially non-deformable, member in the shape of a substantially cylindrical roller having a first curved surface for facilitating the rolling of said member on a firm surface, and a second substantially opposed curved surface adapted to receive at least a portion of the plantar portion of a human foot including at least a portion of the ball of the foot and at least one to-be-treated toe;
• and
• receiving and retaining means for securing a single to-be-treated toe to said second curved surface, said single to-be-treated toe receiving and retaining means attached to said second surface of said member, said means for receiving and retaining a to-be-treated single toe including a toe base block which is shaped and adapted to receive and grasp a to-be-treated single toe;
• whereby, as said member is rolled in a forward direction on its said first curved surface a secured single to-be-treated toe is pulled downward due to the curvature of said first curved surface of said member to thereby impart plantarflexion motion to the MTP joint of that secured single to-be-treated toe, and as said member is rolled in a backward direction, a secured single to-be-treated toe is pushed upward due to the curvature of said first surface of said member to impart dorsiflexion motion to the MTP joint of the secured single to-be-treated toe.
