Ankle rehabilitation apparatus

Abstract

An ankle rehabilitation apparatus is disclosed. The ankle rehabilitation apparatus comprises a base, a rotary plate, a rotary plate, an actuator, a control unit, and a torque detector. The rotary plate is pivotally connected to the base to hold a user's ankle. The actuator has a driving shaft to rotate the base. The control unit is electrically connected to the actuator to control the actuator to rotate the rotary plate. The torque detector is electrically connected to the control unit to detect a torque exerted to the driving shaft, and outputting the torque signal according to the torque to the control unit.

1 . An ankle rehabilitation apparatus, comprising:
 a base having a holding frame, a first holder and a second holder, wherein the holding frame, the first holder and the second holder are adjustable corresponding to a user's bodily form, and the first holder holds the user's thigh, and the second holder holds the user's shank;   a rotary plate pivotally connected to the holding frame of the base, wherein the rotary plate has at least one holding member to hold the user's ankle;   an actuator fixedly mounted to the holding frame of the base, wherein the actuator has a driving shaft for rotating the rotary plate;   a control unit electrically connected to the actuator, wherein the control unit controls the actuator to rotate the rotary plate;   a torque detector disposed between the rotary plate and the actuator wherein the torque detector is electrically connected to the control unit to detect the torque exerted on the driving shaft and outputting a torque signal corresponding to the torque to the control unit.   
   
   
       2 . The ankle rehabilitation apparatus as claimed in  claim 1 , wherein the base has a plurality of assembly holes for assembling the holding frame and the holder on the base. 
   
   
       3 . The ankle rehabilitation apparatus as claimed in  claim 1 , wherein the holding member is a holding belt. 
   
   
       4 . The ankle rehabilitation apparatus as claimed in  claim 1 , wherein the actuator further has a motor to rotate the driving shaft. 
   
   
       5 . The ankle rehabilitation apparatus as claimed in  claim 4 , wherein the torque detector has an isolation member disposed between the motor and the torque detector to isolate the signal noise there between. 
   
   
       6 . The ankle rehabilitation apparatus as claimed in  claim 1 , further comprising:
 a reset counter to detect if the rotary plate returns to the initial status and count the number of rounds that the rotary plate rotates.   
   
   
       7 . The ankle rehabilitation apparatus as claimed in  claim 6 , wherein the reset counter includes a light breaker disposed and arranged corresponding to the user' ankle. 
   
   
       8 . The ankle rehabilitation apparatus as claimed in  claim 1 , wherein the torque detector is disposed on the outer peripheral of the driving shaft. 
   
   
       9 . The ankle rehabilitation apparatus as claimed in  claim 1 , wherein the control unit is a computer apparatus. 
   
   
       10 . The ankle rehabilitation apparatus as claimed in  claim 1 , wherein the control unit is a programmable control chip. 
   
   
       11 . The ankle rehabilitation apparatus as claimed in  claim 1 , wherein the control unit controls the actuation of the actuator according to the torque exerted on the driving shaft. 
   
   
       12 . The ankle rehabilitation apparatus as claimed in  claim 1 , further comprising;
 a display to display a trace point adapted to be tracked by a user to perform a trajectory tracking task.
