Claim 7

The combination of a foot brace to be worn inside a shoe for correcting foot deformation due to cerebral vascular impairment comprising a heel cup for closely embracing the heel and portions of the foot ahead of it and having an upper edge, a clamping means for engaging the leg region immediately above the ankle of the foot and having a lower edge, and two connecting means respectively disposed on opposite sides of the ankle, each of said connecting means including a hinge formed of a single piece of relatively stiff material having limited flexibility and having ends respectively fixedly secured to said heel cup and to said clamping means for interconnecting same so as to provide a space between said upper and lower edges to permit but limit front-to-back flexing of the ankle, whereby the resistance provided by the stiffness of said hinges intensifies the pressure of said heel cup against the portions of the foot ahead of the heel and the shoe holds said heel cup in position on the foot and said clamping means applies pressure to the leg region to enhance the wearer's feeling of angular movement between the foot and ankle as the wearer's foot travels a walking trajectory.

Claim 8

The combination of claim 5 characterized by said clamping means positioned to clamp against opposite sides of the leg and provided with adjustable means for adjusting the clamping pressure against the leg.

Claim 9

The combination of claim 5 characterized by said clamping means positioned to clamp against opposite sides of the leg and provided with adjustable means for adjusting the clamping pressure against the leg, said adjustable means comprising a flexible binder which encircles at least a portion of the clamping means and is adjustable in length to vary the clamping pressure of the clamping means against the leg.

Claim 10

The combination of claim 5 further characterized by said clamping means positioned to clamp against opposite sides of the leg and provided with adjustable means for adjusting the clamping pressure against the leg, said adjustable means comprising a flexible binder which encircles at least a portion of the clamping means and is adjustable in length to vary the clamping pressure of the clamping means against the leg and said flexible binder having locking means for locking the binder in any adjusted length.

Claim 11

The combination in a foot brace to be worn inside a shoe for correcting foot deformation due to cerebral vascular impairment comprising a heel cup having an upper edge and cast to the shape of the wearer's foot corresponding to the wearer's approximate neutral foot position as it was before the impairment for closely embracing the heel and portions of the foot ahead of it, a clamping means for engaging the leg region immediately above the ankle of the foot and having a lower edge, and two connecting means respectively disposed on opposite sides of the ankle, each of said connecting means including a hinge formed of a single piece of relatively stiff material having limited flexibility and having ends respectively fixedly secured to said heel cup and to said clamping means for interconnecting same so as to provide a space between said upper and lower edges to permit but limit front-to-back flexing of the ankle, said connecting means cooperating with said heel cup and said clamping means to resist lateral angular movement between the ankle and foot but to allow such angular movement in a front-to-back direction against the stiffness of said connecting means, whereby the shoe holds said heel cup in position on the foot and said clamping means applies pressure to the leg region to enhance the wearer's feeling of angular movement of the foot and ankle as the wearer's foot travels a walking trajectory and senses resistance to front-to-back movement of the foot provided by the stiffness of said connecting means.

Claim 12

The combination in a foot brace to be worn inside a shoe for correcting foot deformation due to cerebral vascular impairment comprising a heel cup having an upper edge and cast to the shape of the wearer's foot corresponding to the wearer's approximate neutral foot position as it was before the impairment for closely embracing the heel and portions of the foot ahead of it, a clamping means for engaging the leg region immediately above the ankle of the foot and having a lower edge, and two connecting means respectively disposed on opposite sides of the ankle, each of said connecting means including a hinge formed of a single piece of relatively stiff material having limited flexibility and having ends respectively fixedly secured to said heel cup and to said clamping means for interconnecting same so as to provide a space between said upper and lower edges to permit but limit front-to-back flexing of the ankle, said connecting means cooperating with said heel cup and said clamping means to resist lateral angular movement between the ankle and foot but to allow such angular movement in a front-to-back direction against the stiffness of said connecting means, whereby the shoe holds said heel cup in position on the foot and said clamping means applies pressure to the leg region to enhance the wearer's feeling of angular movement of the foot and ankle as the wearer's foot travels a walking trajectory and senses resistance to front-to-back movement of the foot provided by the stiffness of said connecting means.

Claim 13

The combination of claim 9 characterized by said clamping means positioned to clamp against opposite sides of the leg and provided with adjustable means for adjusting the clamping pressure against the leg.

Claim 14

The combination of claim 9 characterized by said clamping means positioned to clamp against opposite sides of the leg and provided with adjustable means for adjusting the clamping pressure against the leg, said clamping means being a strap of "VELCRO" material connected at one end to one side of said clamping means and passing through a loop connected to the other side of said clamping means, whereby said strap can be drawn through the loop and reversed upon itself as said adjustable means.

Claim 15

The combination of claim 9 characterized by said hinges being positioned in recesses in the walls of the foot brace to provide clearance between said connecting means and the wearer's ankle.

Claim 16

The combination of claim 9 characterized by said hinges being positioned forward of the rear of the foot brace and rearwardly of the front of the foot brace, whereby repeated front-to-back angular movement between said heel cup and said clamping means permits said upper edge of said heel cup and said lower edge of said clamping means to intermittently abut, and thickened pad means on each of said edges to prevent bypass of the said edges during said repeated angular movement.

Claim 17

The combination of claim 13 further characterized by said thickened pad means being of soft padding in the regions they abut in order to minimize sound when they abut.
