Abstract
At the time of a twist or a bone fracture of the ankle it is necessary after the plastering to reeducate the ankle motions. In the present invention, a footrest is fastened on a base and may pivot on the base by means of a ball-and-socket joint. Various settings allow this pivoting to be progressive and measured so that the patient or the doctor may follow the reeducation progress, day by day.
Claims20
A device for the progressive rehabilitation of the human foot after accident or malformation comprising
- a base,
- a ball-and-socket joint having a first member fixed to the base and a second member which is spherically rotatable with respect to the first member projecting upwardly therefrom,
- a footrest fixed to said second member of the ball-and-socket joint whereby the footrest is tiltably and spherically rotatably supported with respect to the base,
- a marking means supported by the footrest and extended outwardly therefrom for movement therewith relative to the base, whereby the marking means is capable of marking a curved path, and
- record support means fixed to the base for supporting a markable record in recording proximity to the marking means whereby a permanent record of non-linear, rotating movement of the footrest with respect to the base can be generated, the permanent record having at least two dimensions.

A device for the progressive rehabilitation of the human foot after accident or malformation comprising,
- a base,
- a ball-and-socket joint having a ball fixed to the base and a socket partially enveloping the ball which is movable with respect to the ball projecting upwardly therefrom,
- a footrest fixed to said socket, the socket containing a hole which extends from the footrest to the ball, and the footrest containing a circular threaded hole located above the hole in the socket, the axis of the threaded hole being perpendicular to the footrest, whereby the footrest is tiltably supported with respect to the base,
- a marking means supported by the footrest and extended outwardly therefrom,
- record support means fixed to the base for supporting a markable record in recording proximity to the marking means whereby a permanent record of movement of the footrest with respect to the base can be generated, and
- adjustable spring means internally mounted in relation to the ball-and-socket joint so as to adjust the resistance to tiltable motion of the footrest relative to the base, the adjustable spring means comprising:
- A first washer resting on the ball,
- A spiral spring resting on the first washer, the spring having an axis perpendicular to the footrest,
- A second washer resting on an upper end of the spring,
- A screw engaged in the threaded hole of the footrest, the screw having a lower end in contact with the second washer.
