Background Technology

[0002] As is well known, various methods of physical therapy are being performed for the treatment and rehabilitation of patients who are unable to properly move their upper or lower limbs due to abnormalities in the spinal cord or brain resulting from sequelae of various accidents or diseases.

[0003] In particular, the decline in functional motor ability of the upper limbs caused by spinal cord injury, nerve damage, stroke, etc., reduces the performance of daily activities and the range of social activities. Therefore, treatment and rehabilitation to overcome this require restoring the range of motion of the paralyzed upper limb joints and muscle usage ability to a level close to that of a normal person so that the patient can perform daily activities.

[0004] To this end, various training devices for upper limb rehabilitation have been developed and are being used in physical therapy; however, conventional exercise equipment for upper limb muscle rehabilitation is configured to allow rehabilitation training to focus primarily on upper arm movements centered on the shoulder and elbow.

[0005] However, conventional exercise equipment for the rehabilitation of upper limb muscles as described above has limitations in rehabilitating various upper limb muscles required for movements related to daily life, and thus there is a need for an upper limb rehabilitation training device that enables the rehabilitation of a wider variety of upper limb muscles.

[0030] That is, the handle (60) is configured to be movably installed on the transverse guide rail (40) via the left and right moving member (62) to provide a handle function.

[0031] A load cell (70) is installed at the bottom of the handle (60) to detect the force applied through the handle in the left-right X-axis and front-back Y-axis and transmit it to a control unit (not shown).

[0032] The above control unit is configured to be connected to the first motor (30) and the second motor (50), the load cell (70), etc., and is configured to determine the vector of the direction in which the handle (60) is to move based on information input from the load cell (70), and to control the driving of the first motor (30) and the second motor (50) accordingly.

[0033] The above control unit may be a PC equipped with a predetermined program, a separate independent terminal device, or a smartphone or tablet PC equipped with a predetermined application.

[0035] The above housing (64) is formed in a roughly rectangular shape with a through hole (65) drilled in the center and is fixedly coupled to the left and right moving member (62), and the bearing (66) is provided by being seated and installed within the through hole (65) of the housing (64).

[0036] A protrusion (64a) made of a circular frame is formed protruding to a certain height above the through hole (65) of the housing (64), and a hook (64b) is formed on the inner surface of the through hole (65) so that the bearing (66) is seated thereon.

[0037] The load cell (70) is embedded in the housing (64) and configured to detect the force in the X-axis and Y-axis directions of the force applied through the grip portion (78) of the handle.

[0041] The above-mentioned pressure member (76) is configured such that a coupling projection (76a) is formed protruding from the center of the upper surface of a roughly disc-shaped plate, and is installed on the upper side of one end of the load cell (70), bearing (66), and rotating member (72) to transmit the external force applied through the grip portion (78) to the load cell (70).

[0042] The grip portion (78) is formed in a roughly rod shape with a hole formed inside and is coupled in a manner fitted onto the coupling projection (76a) of the pressure member (76) to perform a handle function and is configured to transmit the force applied by the user to the load cell (70).

[0043] Next, the operation of the present invention as described above will be explained in detail as follows.

[0044] According to one embodiment of the present invention, a pair of longitudinal guide rails (20) are fixedly installed on the base plate (10), and a transverse guide rail (40) is installed so as to be movable in the forward and backward directions on the pair of longitudinal guide rails (20), and a handle (60) is installed so as to be movable in the left and right directions on the transverse guide rail (40), thereby configuring an upper limb rehabilitation training device, the user can place the elbow portion of the upper limb on the seating portion (74) of the handle (60) and grasp the grip portion (78) to perform a predetermined upper limb rehabilitation training.

[0045] First, in Active Assist Mode, as the user grips the grip portion (78) and applies an external force in the direction of movement, the load cell (70) embedded in the housing (64) of the handle (60) detects the force applied in the X-axis and Y-axis directions and transmits it to the control unit, and the control unit can calculate the vector of the direction of movement through the logic of a predetermined program embedded therein.

[0046] In addition, the control unit controls the operation of the first motor (30) connected to the longitudinal guide rail (20) and the second motor (50) connected to the transverse guide rail (40) based on the vector direction detected from the load cell (70). At this time, the control is performed so that the RPM of the first motor (30) and the second motor (50) are synchronized and operated in response to the strength of the force applied by the user, thereby enabling more efficient upper limb rehabilitation training through the rotation of the belts (22, 42) connected to each motor.

[0047] That is, by determining the force of the user's arm movement through the multi-axis load cell (70), upper limb rehabilitation training can be performed by moving the handle (60) provided in a modular form through the movement of the belt (22, 42) according to the driving of the first motor (30) and the second motor (50).

[0048] Meanwhile, in Active Mode, the user can perform upper limb rehabilitation training by moving the handle themselves. In other words, through a designated program, the user can freely perform upper limb rehabilitation training while tracing, filling in blanks, playing games, etc.

[0049] In addition, in Passive Mode, the first motor (30) and the second motor (50) are operated according to a set program under the control of the control unit, thereby enabling passive rehabilitation training for the upper limb of a user holding the grip portion (78) of the handle (60), and at this time, the rehabilitation therapist can adjust the range of motion and speed of the handle (60) through the control of the set program.

[0050] In addition, the range of motion can be verified and controlled by measuring the range of motion (ROM) through a predetermined control means, and the movement of the cursor within the program can also be controlled using the measured ROM value.

[0051] Meanwhile, even if modified embodiments different from those described in the present invention emerge, they should not be understood separately from the technical concept or perspective of the present invention, and are of course included within the scope of the claims attached to the present invention.
